Abstract
Activity schedules are visual support strategies that use visual cues, such as photographs and/or
written words, to teach a learner to engage in a sequence of tasks or activities independently.
Until recently, research on activity schedules has involved one schedule being followed by one
individual. In order to facilitate cooperation between two individuals to complete one task, and
to increase engagement between peers, cooperative activity schedules are being introduced as
interventions in educating students with autism. A multiple baseline design across three activities
was used to assess the effects of including an instructional package consisting of visual cues,
prompting, and feedback to increase cooperation within an activity schedule between two
students with autism spectrum disorder (ASD). This design was replicated across two pairs of
participants. Baseline data indicated a lack of cooperation across both of the pairs. Following
intervention, an increase in cooperation amongst both of the pairs was demonstrated. All
prompting and reinforcement systems were effectively faded out for both pairs, and 2-week and
1-month follow up probes indicated cooperation maintained in the presence of the visual cue.
Cooperative Activity Schedules in Children with Autism Spectrum Disorder
Children diagnosed with autism spectrum disorder (ASD) often present with a range of social
impairments that make it difficult to engage in cooperative behavior with others (Liebal,
Colombi, Rogers, Tomasello, & Wareken, 2008). These include deficits in imitation skills
(Rogers & Pennington, 1991; Griffith Pennington, Whener, & Rogers,1999; Sigman & Ungerer,
1984; Bryson & Smith, 1998), the use of joint attention (Jones & Carr, 2004; Bono, Daley, &
Sigman, 2004; Kasari, Sigman, Yirmiya, 1990; Sigman & Mundy, 1989), and initiating bids for
joint attention (Baron-Cohen, 1987). Imitation plays a fundamental role in the development of
coordinated acts (Liebal et al., 2009). Imitation skills provide children with visual or verbal cues
on how to socially respond in various situations, in relation to peers or others responding within
the same context. Joint attention is the shared focus of two individuals on an object. It is
achieved through eye gazing, pointing, or other verbal or non-verbal acts (Bono et al., 2004).
SPECIAL EDUCATION RESEARCH, POLICY & PRACTICE 6
Impairments in cooperation skills in children with ASD may in part be due to deficits in
imitation and joint attention along with their inability to share intentions and experiences with
others (Tomasello, Carpenter, Behne, & Moll, 2005).
Similar to joint attention, cooperation involves activities with shared goals and intentions (Liebal
et al. 2008). Shared cooperative activities have three main features that consist of cooperating
partners who are 1) mutually responsive to each other, 2) hold a shared goal, and 3) mutually
support each other in their roles in order to achieve that shared goal (Bratman, 1992).
Individuals with ASD tend to demonstrate difficulty engaging in cooperative behavior, either in
play or during social activities, thus leading to difficulties within group teaching contexts
(Spriggs Gast, & Ayres, 2007). Cooperation skills are defined as two students working together
to complete a task. This may involve turn taking and sharing responsibilities of task completion
(Betz, Higbee, & Reagon, 2008). Studies have demonstrated cooperative behavior between
typical toddlers between the ages of 18 and 24 months (Warneken, Chen, & Tomasello, 2006)
and between the ages of two and three in dyads with their respective peers (Ashley & Tomasello,
1998). The results of the above studies indicate that even before their second birthday, typically
developing toddlers are capable of forming a shared goal and then coordinating their behavior
and attention with an adult in pursuit of this common purpose (Warneken et al., 2006).
Deficits in cooperative skills in individuals with ASD can contribute to dependence on
caregivers, teachers, and supervising adults to initiate a task or activity (Copeland & Hughes,
2000). Many intervention packages rely heavily on verbal instructions, modeling, and gestures.
These stimulus prompts are often associated with reinforcement during teaching, and might,
thereby, acquire stimulus control over the target responses (MacDuff, Krantz, &, McClannahan,
1993). Consequently, learners with ASD may become prompt dependent. That is, they fail to
perform target responses independently and rely on interaction with the instructor to complete
the skill and the presence of the stimulus prompts. For example, an individual with autism might
learn a complex behavior chain, such as playing with toys, completing vocational tasks, or
engaging in functional skills, yet often fail to exhibit these responses independent of prompting
procedures (Billingsley & Romer, 1983; Sheinkopf, 2005). Thus, increasing independence in
individuals with ASD is one of the key elements in creating an effective curriculum. In order to
facilitate increased independence in both task completion and social interactions, an activity
schedule may be implemented. Research has demonstrated that activity schedules have been an
effective tool in increasing on task behavior and thereby independence (McClannahan & Krantz,
1999).
An activity schedule is a visual support strategy that uses visual cues, such as photographs and/or
written words, to facilitate following a sequence of tasks or activities independently
(McClannahan & Krantz, 1999). Visual stimuli can be presented in a variety of forms.
Photographs (MacDuff et al. 1993; Jolly, Test, & Spooner, 1993), pictures and line drawings
(Frank, Wacker, Berg, & McMahon, 1985; Pierce & Schriebman, 1994), and symbols and words
(Stromer, Mackay, McVay, & Fowler, 1998) are examples of visual stimuli that can be used
within a schedule to prompt a correct response. The visual component of the activity schedule is
likely a critical component contributing to its effectiveness across situations. The visual
components of activity schedules provide communication as to what and how much work should
be completed, and, often, for how long a duration (Bryan & Gast, 2000). The visual component
also provides a structured teaching environment which makes clear expectations and decreases
SPECIAL EDUCATION RESEARCH, POLICY & PRACTICE 7
the reliance on continuous adult prompting (Schopler, Hearsay, & Mesibov 1995). When visual
cues are used as a primary form of instruction and communication, an increase in skill
acquisition in students with ASD has been noted (Shopler et al., 1995).
Additionally, individuals with ASD often have difficulty initiating the next step in a complex
chain of behavior. As an individual learns to brush his teeth, he may not be able to complete the
steps consecutively without a prompt to initiate each specific skill within the chain (MacDuff, et
al. 1993). For example, the individual may not put the toothbrush in his mouth after putting the
toothpaste on the brush. Activity schedules mediate transitions between activities by using
visual prompts to occasion specific behavior chains. As a result, an activity schedule can
promote independence in a sequence of multiple activities, such as a self-care morning routine.
Activity Schedules and Cooperation
A specific area lacking research is the application of activity schedules to increase cooperation
between students with autism and their peers. As the prevalence of ASD in children rises, the
number of individuals requiring long-term services will also continue to increase (Center for
Disease Control and Prevention, 2012). As the projected costs of treating an individual with
ASD continue to rise as the cost of living increases yearly, the need for cost-effective
interventions that require less direct staff intervention to service larger numbers of clients is an
immediate priority (White, E., Hoffman, B., Hoch, H., & Taylor, B., 2011). Students with ASD
have difficulty functioning within group settings due to a myriad of reasons, including behavioral
concerns when in larger settings (White, et al. 2011) and, therefore, only participate in programs
with 1:1 student-teacher ratios (Harris & Handleman, 2006). In order to make group instruction
more efficient and worthwhile, individuals with ASD would require more independence in
schedule following and transitioning between activities (White et al. 2011).
When using activity schedules, students with ASD typically follow individualized schedules that
target the behavior of one individual at a time. Research that has reviewed activity schedules
and social interactions jointly has typically involved one individual with autism following an
activity that prompts interactions with a partner who is not following an activity schedule, but is
the recipient of the prompted interaction, such as that of a conversation partner (Betz, et al.
2008). In order to increase the efficiency of the technology of activity schedules, the overall
scope should be broadened to include targeting the behavior of more than one individual at a
time.
Because students with ASD have marked impairments in social skills, a cooperative activity
schedule provides the context to teach social skills, such as social interactions, in addition to the
task being targeted for completion. A cooperative activity schedule has been shown to
incorporate the addition of prompting peer engagement in activities, turn taking, and cooperative
play (Betz, et al. 2008). These activities are pertinent to social skill development and are often
neglected in classrooms due to the emphasis of academic programs within a student’s
curriculum. Cooperation within activity schedules may lead to a decrease in reliance on adult
prompts for both activity completion and social interaction, as well as a decrease in the total
duration required to complete tasks. It could also decrease the instructional support needed
within the classroom setting (White, et al. 2011). In this study, a cooperative activity schedule
SPECIAL EDUCATION RESEARCH, POLICY & PRACTICE 8
would require two students to work together to complete one task on one schedule that could be
otherwise completed alone, but would provide opportunities for students to socially interact.
Research on cooperation in activity schedules has focused on teaching pairs of students to work
towards one terminal end goal through cooperative schedules, but has highlighted different
aspects of peer interactions. Cooperative schedules have successfully demonstrated an increase
in peer engagement for students with ASD (Betz, et al. 2008) and more recently, increased
collaborative work in completing vocational tasks (White, et al. 2011).
Betz, Higbee, & Reagon (2008) focused on teaching preschool students with ASD to follow joint
activity schedules that cued both individuals to engage in interactive games with each other.
During baseline, the two children were asked to go play. Specific board games were already
selected and no activity schedules were present. During teaching, a joint activity schedule was
present. The results indicated low levels of engagement during baseline, which, following
intervention, reached or surpassed criteria, and were maintained across the maintenance phase.
Overall, joint activity schedules were effective at increasing peer engagement across all three
dyads.
The second study by White et al. (2011) that specifically looked at joint activity schedules also
demonstrated success. The tasks selected for this study included teaching three different adapted
living skills. Baseline included completing the task without prompts, reinforcers, or error
corrections. The session ended when the task was completed or when three 1-minute intervals of
non-engagement occurred. Intervention consisted of teaching and probe sessions. Teaching
sessions incorporated prompting the participants to complete only their designated portion of the
behavior chain. During probe sessions, participants were asked to complete the tasks. The results
indicated that all three groups were able to meet criterion to complete a single activity schedule
together. Overall, participants cooperatively worked together on one activity schedule to
complete tasks. The key factor in both of these studies is that selected participants were able to
fluently follow independent activity schedules, and the goal was to increase cooperative behavior
within their dyad.
These studies are important for a number of reasons. Due to increased difficulty children with
autism have with social interactions (Sheinkopf, 2005), using activity schedules to promote peer
engagement, cooperation during tasks, and cooperative play amongst children is a new area of
research to be explored. As the results indicate, following independent schedules may facilitate
the mastery of two individuals jointly following a schedule (White, et al. 2011). It should also be
noted that following an activity schedule cooperatively is a distinct skill compare with following
one independently (Betz, et al. 2008; White, et al. 2011). Currently, there is a need to replicate
these studies in order to support and build on these findings. The research question that was
investigated in this study was: Do activity schedules with embedded cues for cooperation
increase cooperative behavior in students with ASD? This study examined the effects of visual
cues, prompting, and feedback within activity schedules on increasing cooperation between pairs
of children with autism.

Method
Participants
Participants included four children diagnosed with ASD between the ages of 9 and 14 years who
were enrolled in a special education school that utilizes the principles of applied behavior
analysis. The first pair included a fifteen-year old male, Landon, and a fourteen- year old
female, Alana. The second pair included a 9 year- old male, Dennis, and 10- year old male,
Joey. Participants were selected based on their abilities to independently and accurately follow
picture activity schedules and their results from the Vineland Adapted Behavior Scale. All
participants were diagnosed with autism as toddlers by medical physicians according to DSM-IV
(2000) criteria. All participants exhibited deficits in language, socialization, adapted living,
vocational, and cooperation skills.
Setting
All sessions were conducted in the participants’ school building (a special education school for
children diagnosed with ASD), either in the classroom or the school kitchen, depending on the
activity being targeted. Sessions lasted approximately 20 minutes in duration and occurred five
times per week.
Materials
Cooperative Activity Schedules. Activity schedules for both pre-training and intervention
sessions were designed based on participant need. All materials necessary to complete the
designated vocational tasks were located within the work center (e.g., spray bottle, rags).
Activity schedules were created with word descriptions of the activity in list format (e.g., replace
the staples). Each participant was assigned to three different activities per dyad group, which
included cleaning the office, cleaning the kitchen, and putting away laundry. Participants had no
prior experience with the specified vocational tasks prior to the start of the study. All activity
schedules were printed on 8-inch by 5-inch, white laminated paper. Times new roman font was
used consistently throughout the schedules, with size 36 font for the student’s name, followed by
size 24 font for the steps to each activity. All tokens were round, blue poker chips, 1.5 inches in
diameter. A Sony Handycam 16 gigabyte camera with 3.3 pixels was used to video record all
sessions throughout the study.
Vineland Behavior Adaptive Scales. The Vineland Adaptive Behavior Scales, 2
nd
Edition
(VABS-2; Sparrow, Cicchetti, & Balla, 2005) provides a comprehensive assessment of typical
performance of the day-to-day activities required for personal or social sufficiency as perceived
by the individual(s) completing the form. Community-University Partnership evaluated the
reliability and validly of the Vineland-II (CUP, 2011). The overall Vineland is broken down into
five domains. These domains include communication, daily living skills, socialization, motor
skills, and maladaptive behavior domains. The domains focused on in this study include
communication, socialization, and daily living skills.
Dependent Variables and Measurement Procedures
Schedule Following. Data were collected on the percentage of trials with correct responding
across schedule-following components throughout all phases. Correct responding was defined as
a participant checking the schedule, crossing off the next step with a dry erase marker prior to
completing the step, completing the first or next consecutive step in the activity schedule as
SPECIAL EDUCATION RESEARCH, POLICY & PRACTICE 10
outlined by the listed photographic schedule accurately, and returning to the schedule to see the
next step not checked off. Each step was scored separately, although all steps must be completed
independently and accurately for the trial to be scored as correct. Participants were directly
observed, and data were collected by scoring a plus or minus on the data sheet during probe
sessions. Probe sessions were conducted every third session throughout the study.
Percentage of Cooperative Steps Completed. Data were collected on the percentage of
opportunities in which cooperation with a peer occurred throughout all phases. Five
opportunities for cooperation were programmed into the schedule during each session for each
dyad. Cooperation was defined as two students working together to complete one task on one
schedule. These tasks could be completed alone but provided an opportunity for students to
interact with each other. For cooperation to be scored as correct, an interaction between the two
participants to complete one portion of the task occurred, which included one participant vocally
requesting assistance from his/her peer, and then both participants completing the next step
within the chain together in its entirety. Data were collected on individual steps, but all steps had
to be independent and accurate for an opportunity of cooperation to have successfully occurred.
Following cooperation, the participant who asked for help thanked the second participant for
helping, which indicated the task was completed and that the participant could return to his/her
own schedule. Data were scored on whether the second participant returned to his/her original
task (schedule). Throughout schedule following, data were also collected on accuracy of the
participants completing the schedule of tasks. Participants were directly observed and data were
collected during probe sessions by scoring a plus or minus on the data sheet.
Frequency of Request for Help. Data were collected on the frequency of prompted requests
throughout the activity schedule for each peer. Data were also collected on spontaneous requests
for help or assistance that occurred throughout sessions in the absence of the picture cue.
Participants were prompted to respond by saying “thank you” following completion of helping to
indicate they were finished and could return to their own schedule. Participants were directly
observed, and data were collected on a frequency of prompted and independent “thank you”
responses during probe sessions.
Experimental Design and IOA
A multiple-baseline-across-activities design was used to evaluate the effects of an instructional
package which included a visual cue, prompting, and feedback, on increasing cooperative
behavior during tasks between two children with ASD. This design was replicated across two
participant dyads. Inter-observer agreement (IOA) data were obtained for 30% of all sessions
conducted across all conditions by a second trained observer. Agreement was calculated by
dividing the number of agreements by the total number of agreements plus disagreements and
multiplying by 100. An agreement was defined when both observers scored a response as either
correct or incorrect. IOA data averaged 97% agreement for schedule following and ranged
between 94% and 100%, 100% agreement for opportunities when cooperation occurred, and
100% agreement for frequency of spontaneous requests for help across baseline and training.
Procedural integrity was obtained for 30% of sessions as well. Procedural integrity was
calculated by examining the total percentage of opportunities in which the procedure was
correctly implemented across two observers. Data were collected on the following components:
use of the correct schedule, use of the correct materials, correct placement of materials, correct
SPECIAL EDUCATION RESEARCH, POLICY & PRACTICE 11
verbal instruction to begin the activity, correct dyad pairing, proper instruction and prompt
fading, and correct reinforcement schedule. Procedural integrity data averaged 100% for use of
the correct schedule, 100% for use of the correct materials, 100% for correct placement of
materials, 97% correct verbal instruction to begin the activity with a range of 93% and 100%,
100% for correct dyad pairing, 94% for proper instruction and prompt fading with a range of
91% to 100%, and 97% for correct distribution of the reinforcer with a range of 94% to 100%
across both baseline and training.
Social Validity
To assess social validity, classroom teachers of the participants were provided an anonymous
questionnaire to complete prior to the start of the study, and following the completion of the
study. The questionnaire included questions to assess: (a) if the overall outcome of the study is
meaningful to the participants’ lives, (b) the overall social acceptability of the treatment, (c) the
teacher’s satisfaction with the amount of helping going on within the classroom, and (d) the
feasibility of implementation for teachers in their own classroom. Participants were asked to
answer questions using a Likert scale, ranging from one to five, with one equaling strongly
disagree, two being disagree, three being neither agree or disagree, four being agree, and five
strongly agree. Additionally, normative data were collected on typically developing individuals
of the same age as the participants (9-14 years of age) to determine how much helping is
standard when completing such tasks.
To assess social validity, six videos were shown to four observers who were naïve to the
experimental conditions. Viewers were teachers at the school the participants attended but were
not the participants’ teachers. Videos consisted of both baseline and intervention clips. Videos
provided an array of clips, showing cooperation, no cooperation, and varying amounts of
cooperation. Viewers that were not involved in the study were asked to score cooperation
throughout the clips using a Likert scale, ranging from one to five, one equaling not cooperative,
two being not very cooperative, three being neither cooperative or not cooperative, four being
cooperative, and five being very cooperative.
Procedure
Task Selection. Tasks were selected through interviews of the participant’s teacher, direct
observation, and the Vineland Adapted Behavior Scales. The tasks selected were based on total
number of steps to completion and total duration of time required for task completion; all tasks
were similar in duration. For example, cleaning a table and making the bed are within the same
relative duration for completion and may thus be selected versus cleaning an entire room and
making the bed, which vary widely in the duration of time required to complete the task. The
duration of completion for these tasks was assessed through a competent performer. An example
of a potential schedule for cleaning the kitchen includes 10 steps to completion (see Figure 1 for
example of cleaning the kitchen schedule).
SPECIAL EDUCATION RESEARCH, POLICY & PRACTICE 12
Figure 1. Steps contained within cleaning the kitchen
Pre-training. Prior to the study, participants were trained to follow activity schedules to
complete three different tasks independently. The activity schedules consisted of cleaning the
kitchen, organizing the office, or folding laundry.
Graduated guidance with spatial fading was used to manually prompt activity schedule following
responses and task completion. Manual prompts were always delivered from behind the
participant. An unspecified prompt fading procedure was implemented, where upon moment-to-
moment decisions about prompting and fading were made based on the participant’s
demonstration of the skill. Fading started by moving from a full physical prompt to a less
intrusive prompt, until independence was achieved. Initially, hand-over-hand manual guidance
was provided, with the experimenter first guiding the participants’ hands, then elbows, and then
upper arm (White, et al. 2011). Following changing the location of the prompt, the experimenter
shadowed the participant. The experimenter followed the participants’ movement, without
touching them. The distance of shadowing was increased from one to three meters between the
participant and the experimenter (White, et al., 2011).
Participants were prompted to check the step off in the activity schedule with a dry erase marker
prior to completing the step. No verbal prompting was used and teaching continued until
participants independently achieved 100% accuracy in responding across two consecutive
sessions with the experimenter three meters away. Tokens were provided contingent on
correctly completing a step of the chain, and were exchanged for other primary or secondary
reinforcers (e.g., candy, computer games) following the completion of the task. The
experimenter approached the participants’ and showed them the actual delivery of the token in
their respective bags. Participants exchanged tokens for their self-selected reinforcers following
completion of the activity schedule. For safety purposes, the occurrence of maladaptive behavior
would have resulted in the termination of the session, however, this did not occur for either dyad
group throughout the study. This procedure was replicated across all three activities selected for
each participant during the skill assessment.
Baseline. During baseline, both participants in a dyad were present, were provided with
sufficient materials to complete a task in parallel and could, at any time, work cooperatively.

SPECIAL EDUCATION RESEARCH, POLICY & PRACTICE 13
Participants were initially instructed to follow one presented activity schedule acquired during
the pre-training phase (See Figure 2 for baseline example).
Figure 2. Steps contained within baseline schedule for doing laundry.
Both participants individually demonstrated mastery (100% independent accurate responding) of
the selected tasks prior to beginning baseline measures. Participants were set up at one work
station and had access to one schedule and the needed task materials. Throughout the baseline
condition, participants were presented with the instruction, “Let’s work together to complete
(specific activity).” No prompting, error correction, or reinforcement was provided during
baseline. Visual cues to prompt cooperation were not provided in the schedule. Sessions were
scored for percentage of independent and accurate responding, percentage of cooperation
between the two peers, and frequency of requests for help. If both participants had stopped
working for a duration longer than 3 minutes, the activity would have been ended. This did not
occur for either participant dyad group.
Intervention. The cooperative schedule incorporated visual cues for cooperation embedded
throughout the activity schedule with their assigned peer on the same task they previously had
acquired individually during pre-training (See Figure 3 for schedule with opportunities of
cooperation).
SPECIAL EDUCATION RESEARCH, POLICY & PRACTICE 14
Figure 3. Steps contained within cooperation schedule for cleaning the office.
The sequential placement of the give/take picture was consistent throughout the schedule. In
each session, five cues for cooperation were embedded into the schedule for each activity for
each dyad pair. These opportunities were indicated through a give/take picture, which depicted
a hand placing an item into another hand. The picture indicated the need for the other participant
to ask for help. Participants stopped their current activity and were vocally prompted, “I need
help,” or “Can you help me?” following sight of the picture depicted in the schedule. All vocal
prompts were faded out systematically until participants were vocally requesting for help
following just the sight of the picture. No gestures to the picture were required throughout initial
training, as the picture aligned with the task precisely. For example, a participant (1) checked the
schedule, (2) crossed off the step, (3) completed the actual step, and (4) returned to the schedule.
For specific examples of cooperation, a participant (1) checked the schedule, (2) crossed off the
step, (3) vocally asked the other participant for help, (4) completed the step with the other
participant, and (5) returned to the schedule. Manual guidance was used to facilitate helping, if
the participant that was the recipient of the request failed to help after three seconds of the
request. Prompting and fading procedures were the same as in the pre-teaching condition.
During teaching sessions, one participant was asked to begin the activity schedule and
immediately guided to check off the first item indicated. For each selected activity, five
opportunities for cooperation were identified. For example, if cleaning the kitchen was the
selected target in the 10-step task analysis, five opportunities to request for assistance from the
assigned peer were identified through a give/take picture icon. These opportunities included one
participant completing the step in the activity schedule, followed by requesting help when the
give/take picture was present, and the two participants completed the step cooperatively. The
participant who asked for help returned to the schedule and crossed out and completed the next
step in the activity schedule, while the other participant returned to the step he was completing
before helping his peer (See figure 4 for schedule example).

The order of which participant started the activity schedule was randomized so that the same
participant did not start the activity schedule daily. Manual guidance was used as needed to
prevent any errors.
Tokens were provided contingent on correctly completing a cooperation opportunity, defined as
requesting for help and the peer completing the next step in the schedule, and were cashed in
following the completion of the task. The experimenter went over to the participant and
delivered the tokens in their respective bags on their workstation. Participants later exchanged
their tokens for their self-selected reinforcers following completion of the activity schedule.
Probe sessions. Probe sessions were conducted after every third teaching session and followed
the exact same contingencies as in baseline, except the give/take picture was embedded within
the activity schedule. Teaching sessions were terminated once mastery criteria of 95%
independent and accurate responding was achieved. All subsequent sessions were probe sessions
and a proximity fading procedure was implemented. The fading procedure involved increasing
the distance between the experimenter and the participant in 1-meter increments (beginning with
immediately behind the participant and ending across the room from the participant) following
each probe session at 95% independent and accurate responding.
Generalization Sessions. Generalization sessions were conducted to assess if cooperation would
occur with a novel peer, in different settings, and with different activities. Participants were
presented with a novel activity with a novel partner in a novel setting and assessed to see if
generalization occurred from the original peer, setting and activity. During generalization
sessions “help” cues were embedded throughout the schedule. Additionally, baseline probes

were conducted every 6

picture was removed from the activity schedule.

Pre-training
The results of pre-training demonstrated steady acquisition of all three tasks by all four
participants (See Figures 5 and 6). Figures 5 and 6 depict the acquisition rate, which ranges from
4 to 7 sessions for all participants to reach mastery.

Landon demonstrated the quickest rate of mastery, averaging four sessions per activity to meet
mastery. Figures 5 and 6 also depict schedule following during pre-training. All participants
initially required prompting to check off the step prior to completing it. All participants met
mastery criteria and remained consistent with schedule following throughout all conditions.
Baseline. All four participants acquired the skill of independent schedule following during pre-
training and maintained it during baseline (see Figures 7 and 8). Throughout baseline, Landon
made one error following his schedule during the kitchen task, but maintained at 100% accuracy
for both the office and laundry (see Figure 7). Alana maintained schedule following, also
having one one error during the kitchen task (see Figure 7). Joey was the most inconsistent with
schedule following, with an error during the kitchen task, and multiple errors made during the
laundry task (see Figure 8). Dennis maintained schedule following, also having one error during
the kitchen task (see Figure 8). Throughout both baseline and intervention, participants
maintained schedule following with minimal errors that did not impede their abilities to maintain
the correct sequence of tasks. In order to be scored as a correct trial, all four parts involving
following the schedule had to be correct. Figure 9 and 10 show the percentage of independent
cooperation instances throughout baseline. During baseline, Landon and Alana engaged in
cooperation on 0% of all five presented opportunities. No spontaneous requests for help were

Figure 9 depicts the percentage of opportunities for cooperation for Landon and Alana, with
results indicating that the pair met criteria for cooperating on 100% of opportunities, maintaining
when both the proximity of the instructor and the reinforcement schedule was faded out. Two
week and one month follow up probes depict cooperation maintaining, in the absence of both the
instructor and the tokens. Landon and Alana reached criteria, 100% cooperation across all five
presented opportunities after one probe session, which was preceded by three teaching sessions.
Following 100% cooperation in the probe session, Landon and Alana remained at criteria
throughout the fading of both the proximity of the experimenter to across the room and the
removal of the reinforcement system. During baseline probe conditions when the cue for help
was removed, Landon and Alana engaged in 0% cooperation during the five-presented instances.
Two week and one month follow-up probes depict cooperation maintaining at 100% throughout
the five opportunities when the cue is present, with both the experimenter across the room and
the reinforcement system removed. Throughout intervention, no spontaneous requests for help
were made by either Landon or Alana.
The percentage of cooperation for Joey and Dennis is demonstrated in figure 10, with results
indicating the pair met criteria for cooperating on 100% of opportunities, maintaining when both
the proximity of the instructor and the reinforcement schedule was faded out. Two week and one

Landon and Alana both requested help from the novel peer assigned in their dyad in a different
classroom, with a novel activity of cleaning the classroom, 100% of the time. The novel peer did
not always reciprocate engagement in cooperative behavior. For Landon, he received the
assistance of the novel peer 100% of the time. Landon returned back to his schedule 100% of
the time, but the novel peer did not. Alana asked for help for 100% of all opportunities. She
received help from the novel peer on 66% of possible opportunities. She returned back to her
schedule accordingly on 100% of the opportunities. The novel peer did not. Joey and Dennis
also cooperated on 100% of the opportunities presented with the novel peer. Joey had 80%
assistance from the peer once requested, and returned to the schedule 100% of the time. Dennis
had 100% of cooperation from the peer, and also returned to the schedule 100% of the time.
Throughout the probe, the novel peer never asked for help when the cue was present.
Social Validity. Results of the survey given to the classroom teachers regarding the participants
indicated no change in how teachers viewed cooperation within their classrooms from pre-test to
post-test. Video clips were shown to viewers not familiar with the study to assess whether they
felt the video clip demonstrated cooperative behavior on a scale from 1-not cooperative to 5-very
cooperative. Videos 1, 4, and 6 all demonstrated instances of cooperation. Video clips 2 and 5
demonstrated no cooperation, and two participants working next to each other, but not together.
Video clip 3 showed participants cooperating on 2 out of 5 potential opportunities, demonstrating
minimal cooperation. Results of the video clips indicate that all four novel viewers agreed that
videos 1, 4, and 6 were a score of 5-very cooperative. The video clips for video 1, 4, and 6 all
demonstrated cooperation occurring. The scorers agreed 100% that videos 2 and 5 were a score
1-not cooperative. The video clips for 2 and 5 demonstrated no cooperation, and showed two
participants working parallel to each other. Video 3 was a video clip that showed participants
SPECIAL EDUCATION RESEARCH, POLICY & PRACTICE 22
minimally cooperating, on 2 out of 5 opportunities. Two of the scorers stated video 3 was a
score of 3-neither cooperative nor not cooperative and two scored it as 2-not very cooperative.
Overall, the results indicated a high level of agreement that cooperation did occur in the videos
amongst all novel viewers.
Normative data specifically geared to the participants’ ages and genders were collected on two
children, one 12-year-old male and one 13-year-old female. While cleaning the office,
cooperation occurred on 4 out of 5 tasks; during cleaning the kitchen, cooperation occurred for 3
of 5 tasks; and while doing laundry cooperation occurred during 4 of 7 tasks. The results
indicated similar results between the normative data and the participants throughout the
intervention.
Discussion
To facilitate learning and improve education for students with ASD, it is necessary to investigate
interventions that create more opportunities for students to gain independence, while moving
away from one to one instruction, as appropriate. The results of this study indicate that using an
activity schedule with a visual cue for cooperation, prompting, and feedback increases
cooperation between two students with autism. Cooperative activity schedules offer two students
the opportunity to collaborate on a task, thus increasing opportunities for social engagement and
interactions, while decreasing the duration of the task (Betz, et. al., 2008). It is feasible that long
term effects include achieving levels of independence that are necessary for improving the
quality of life for individuals with ASD.
The results of this study indicate that adding a visual help cue to signal cooperation into an
activity schedule increases cooperation among students with ASD in a classroom setting. The
results of this study aligned with the results of Betz and colleagues (2008) as well as White and
colleagues (2011) in demonstrating that cooperative activities schedules can increase cooperation
amongst participants. As the results depict, the participants in this study rapidly acquired the
skill of asking for help in the presence of a cue and maintained the skill at follow up. Both pairs
acquired the skill after only three teaching sessions, allowing for the schedule of reinforcement
to be thinned rapidly. The skill of asking for help maintained in both a two week and one-month
follow-up, indicating that the use of a visual cue with prompting and feedback could be a viable
treatment package for students with autism in classroom settings. Due to the staffing ratios in
classrooms and the push for students to spend more time working in groups, having a treatment
that is maintained once the presence of the instructor and the reinforcer is faded out is important
for the long term.
As White and colleagues (2011) describe, prerequisite skills for following activity schedules
vary from following cooperative activity schedules. Following independent activity schedules
proficiently is definitely an important pre-requisite to following cooperative ones. White and
colleagues (2011) noted the importance of the participant mastering the activities within the
schedule prior to introducing it cooperatively. Within this study, participants were required to
master the complete activity schedule individually prior to having the schedule introduced
cooperatively.
SPECIAL EDUCATION RESEARCH, POLICY & PRACTICE 23
In the current study, during baseline probes in which the visual cue was removed, instructions
alone were not sufficient to increase cooperation. Although the experimenter’s instruction at the
start of the activity was, “Let’s work together to clean the kitchen” (or other respective activity),
during these sessions, the participants did not cooperate on tasks, and instead returned to
completing the activities parallel to each other. This occurred for both dyads. Prior to prompting
participants to ask for help in the presence of the cue, the participants did not attempt to help
each other or complete the others respective tasks. With no cue present, cooperation did not
occur across either pair of participants. Additionally, neither pair spontaneously requested for
help throughout the study. A possible explanation for this is the fact that the response of
requesting help was never systematically targeted for reinforcement. Additionally, the picture
cue served as a prompt for the response, and was never faded; therefore, it is highly likely that
the picture cue acquired stimulus control, thus the participants did not request help when the
picture cue was not present.
There are limitations to this investigation. First, not knowing what specific variables(s) is
responsible for the increase in cooperation among the participants. Participants were instructed
to work together to complete a task, and the verbal directive alone was not enough to increase
cooperation. It is unknown if the total package or selected parts of the intervention package is
what increased responding. A component analysis would need to be done to fully determine
which component(s) was responsible for the change in behavior. Specific consideration should
be paid to the effect, if any, token reinforcement had on cooperation due to rapid acquisition but
lack of demonstration of the skill in the absence of the visual cue.
A second limitation is that the results did not generalize for requesting help in the absence of the
visual cue. Additionally, participants did not spontaneously request help from each other for
activities in which the picture was absent. Although following a schedule with built in
opportunities for cooperation is a skill, it is useful to look at how the skill of requesting help can
be broadened to facilitate asking for help spontaneously or in the absence of a picture prompt, or
when help is actually needed (e.g. requesting help because you want to finish sweeping faster
versus requesting help because you cannot lift something alone).
A third limitation is that the results of the teacher survey indicated no change in teacher’s
perceptions of cooperation within their classrooms following the end of the study. This may be
due to the questions not specifically representing the goal of the questionnaire effectively. The
questions may have been too vague, and did not necessarily represent the specific objectives of
the study directly. Additionally, the questionnaire did not provide the definition of cooperation
as used for this study. Thus, teachers may have defined cooperation differently and felt they had
cooperative students prior to the study. However, it should be noted that in anecdotal
discussions with the teachers following completion of the survey, they did report the students as
being more cooperative in their day-to-day activities with peers following completion of the
study.
To increase the number of spontaneous requests for help and generalization of the response in
absence of the visual cue, future studies should look at establishing contingent reinforcement for
engaging in the response of requesting for help, fading the visual cue, and increasing the
response for requesting for help when it is actually needed. As discussed in the limitations, the
response for requesting for help was never systematically targeted for reinforcement. Future
SPECIAL EDUCATION RESEARCH, POLICY & PRACTICE 24
research might consider providing reinforcement contingent on requesting for help as this might
strengthen the response in addition to providing a reinforcer at the end of the chain of
cooperative behavior.
Within this study, all opportunities to request for help were generated to encourage cooperation
between two participants, however help was not actually required to complete the activity (e.g.
moving a heavy table). Future research might look at including opportunities for participants to
ask for assistance throughout the schedule during times when it is actually needed. One of the
ways in which to address this may be to select tasks where help will be required as opposed to
instructed. This would likely increase the student’s motivation to ask for help in the moment.
In this study, the response of requesting for help was not demonstrated in the absence of the
visual cue; therefore, it is likely that the cue served as a discriminative stimulus. Future research
might consider strategies to fade the visual cue, as this would potentially serve to decrease
prompt dependency on the cue. Furthermore, it would potentially increase independent and
spontaneous requests for help since responding came under the control of the help stimulus
rather than the actual tasks.
Future research might also consider including the ability to wait as a criterion for participant
selection. White et al., (2011) mention that instructing students to wait may be an important area
to target when tasks in the schedule must be completed in a specific order. For example, if the
steps include washing the dishes and then drying the dishes, the dishes must be washed prior to
being dried. In this study, the participants who were selected all demonstrated the ability to wait
throughout the study, although this was not initially planned during participant selection.
In summary, teaching students with ASD in dyads and groups needs to become a focus of future
research. Settings for children with autism are frequently no longer supporting ratios that sustain
one to one instruction, thus, students are being expected to perform in groups without the proper
pre-requisite skills. As the number of students assigned to therapists increases, so does the need
for students to be able to work independently under lean schedules of reinforcement and without
close proximity to instructors. These findings further the research on cooperative activity
schedules, and continue to support the need for instruction to incorporate cooperation throughout
group instruction.
