Effectiveness of Social Skills Interventions Incorporating Peer Interactions for Children With Attention Deficit Hyperactivity Disorder: A Systematic Review Ashley Fox, Stephanie Dishman, Mary Valicek, Karen Ratcliff, Claudia Hilton

Importance: Few studies examining the use of peers during interventions have been published, and no systematic review has been conducted to evaluate the available literature.

Objective: To examine the effectiveness of social skills interventions incorporating peers for children with attention deficit hyperactivity disorder (ADHD) to improve social interactions.

Data Sources: A search of five databases (CINAHL, PubMed, Web of Science, Google Scholar, and PsycINFO) produced 697 articles. Sixty-one were retrieved for full-text review, and 15 articles met inclusion criteria.

Study Selection and Data Collection: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to abstract data. Inclusion criteria: Participants younger than age 18 yr with any ADHD pattern, social skills interventions with peer involvement, outcome measures within the domain of occupational therapy, written in English, and involved a peer as the sole or primary component at some point in the social skills intervention. Exclusion criteria: Studies older than 20 yr or that used participants with comorbidities or multiple conditions.

Findings: Interventions incorporating both peer categories were effective for increasing play skills, reducing undesirable social behaviors (e.g., inappropriate verbalizations, dominant behaviors, aggression), and improving communication (e.g., pragmatic language, collaboration, joint participation) and social participation. Improvements were maintained over time, as evidenced by follow-up studies.

Conclusions and Relevance: Outcomes of these studies demonstrate moderate evidence that supports the use of social skills interventions incorporating peers for children with ADHD to improve social interactions, supporting their use by occupational therapists and the need for more studies.

What This Article Adds: This article provides guidance to occupational therapy practitioners on social skills intervention options for children with ADHD.

For many people with attention deficit hyperactivity disorder (ADHD), interactions with peers can be challenging.Approximately 6.1 million children ages 2–17 yr in the United States have a diagnosis of ADHD (Centers for Disease Control and Prevention, 2018). According to the Diagnostic and Statistical Manual of Mental Disorders (5th

ed.; American Psychiatric Association [APA], 2013), ADHD is defined as a pattern of inattention, hyperactivity, or both

(i.e., combined). Inattention can lead to difficulty with maintaining attention to tasks, difficulty organizing and planning

activities, and ease of becoming distracted (APA, 2013). Hyperactivity is evident in problems such as fidgeting, leaving

the classroom at inappropriate times, having difficulty waiting for one’s turn, and interrupting others. Because of these

issues with attention and hyperactivity, children with ADHD are aversive to peers and have lower social skills necessary

for engagement in social participation than do typically developing (TD) peers (Mikami, 2010; Mrug et al., 2012;

Waschbusch, 2002; Young & Amarasinghe, 2010).

Research Article

Social Skills Deficits in Children With Attention Deficit Hyperactivity Disorder Social skills are the competencies people use to communicate, learn, get needs met in appropriate ways, get along with

others, make friends, develop healthy relationships, protect themselves, and interact with society (Dowd & Tierney,

2017). Social dysfunction is a common characteristic among children with ADHD (Hoza et al., 2005). Hodgens et al.

(2000) found that children with hyperactive or inattentive forms of ADHD can experience peer rejection in as little as a

few hours after meeting a new peer. Negative social behaviors can vary depending on the subtype of ADHD. Children

with hyperactive or combined ADHD more frequently demonstrate impulsive actions and aggressive characteristics

that are sources of annoyance to their peers. Children with the inattentive type of ADHD display socially withdrawn

behaviors and often make inappropriate social statements because of lack of awareness of the feelings of others or

difficulty managing their own emotions (Hodgens et al., 2000).

Impact of Social Skills Deficits The symptoms and social characteristics associated with ADHD often result in social dysfunction and lead to peer

rejection and less meaningful friendships (Mrug et al., 2012). Children with ADHD were found to be twice as likely as TD

children to have no friends (Hoza et al., 2005); of those who reported having friends, 56% of those friends did not

consider these children to be their friends. Even when children with ADHD have friends, the friendships tend to be of

lower quality and less stable than those of their TD peers (Hoza et al., 2005) and to last a shorter time than friendships of

TD children (Normand et al., 2011).

Social dysfunction, peer rejection, and poor friendship quality can persist over time if not resolved. Constant social

difficulties and peer rejection have been associated with adverse outcomes later in life (Mrug et al., 2012). In an 8-yr

follow-up of children with ADHD, Mrug et al. (2012) found that symptoms of ADHD were correlated with higher levels of

substance abuse and depressive symptoms. Peer rejection was positively associated with delinquency, smoking,

anxiety, and social impairment, whereas friendship was associated with lower delinquency and lower depressive

symptoms.

Need for Peer Involvement Because problems with peer relationships are likely a causal factor in persistent long-term impairments, approaches

that address peer relationships are important (Mrug et al., 2012). Of the currently accepted interventions targeted at

social skills improvement, those involving TD peers in treatment have been shown to result in improved generalization

(Ang & Hughes, 2002; DuPaul & Weyandt, 2006). This outcome was especially true when the same peers engaged in

social interactions outside of treatment sessions in an environment where practice, corrections, and reinforcement could

occur organically (Ang & Hughes, 2002; DuPaul & Weyandt, 2006). Incorporation of peers in parent training inter-

ventions also has demonstrated the potential to improve positive social behaviors and friendship development

(Antshel, 2015).

Few studies examining the use of peers during interventions have been published, and no systematic review has

been conducted to evaluate the available literature. A systematic review is warranted to clarify the effectiveness of peer

inclusion during social interventions for children with ADHD. The objective of this systematic review, therefore, was to

evaluate whether social skills interventions incorporating peers are effective in improving social skills in children with

ADHD. The knowledge gained from the studies included in this review can be implemented in practice to improve social

participation in children with ADHD while reducing peer rejection and the negative long-term outcomes resulting from

social dysfunction.

Method Search Strategy Intervention studies from peer-reviewed journals were selected for this systematic review on the basis of a topic and

search protocol agreed on by members of the research team (the authors). Databases searched were CINAHL,

PubMed, Web of Science, Google Scholar, and PsycINFO. Other sources included to ensure a comprehensive search

of the literature were reference lists from published literature and hand searches of electronic journals. The aim of our

review was to examine the effects of social skills interventions for children with ADHD that included some type of

interaction with peers and outcome measures within the domain of occupational therapy.

Selection Criteria To meet inclusion criteria, studies had to have participants younger than age 18 yr with any ADHD pattern, provide a

social skills training intervention with peer involvement, use outcome measures within the domain of occupational

therapy, and be published in English. Studies needed to use a peer as the sole or primary component at some point in

the social skills intervention (search terms are listed in Table 1). Peers were defined as TD children, children with

ADHD, playmates, schoolmates, or siblings who were similar in age to the children with ADHD. Initially, only publications

in the past 10 yr were included, yielding 10 articles, so search criteria were expanded to the past 20 yr to provide more

comprehensive coverage of the available literature, yielding 15 articles. All review databases, including the Cochrane

database, were screened for systematic reviews on social skills interventions for children with ADHD that included peers

to ensure that the systematic review had not already been completed.

Studies that addressed adults with ADHD and articles written in a language other than English were excluded.

Additionally, studies that used participants with comorbidities or multiple conditions, such as autism spectrum disorder

and conduct disorder, were excluded to prevent characteristics that were not consistent with ADHD diagnoses from

affecting the results of the interventions.

Procedure Each member of the research team performed comprehensive searches and screened the results on the basis of the

inclusion criteria. From there, the team, with the guidance of additional experienced researchers, discussed and

analyzed the full-text articles to determine which studies to include in this systematic review. Each article was reviewed

by at least two team members to ensure accuracy of data. Disagreements were addressed by involving the rest of

the research team and outside researchers until a consensus was reached (for a diagram of the flow of articles through

the selection process, see Figure 1). Finally, the data were compiled into an evidence table (Table A.1 in Appendix A)

and classified by level of evidence on the basis of the American Occupational Therapy Association’s (2017) Guidelines

for Systematic Reviews, which are based on Sackett (1989).

Results Fifteen studies met the inclusion criteria (1 Level I study, 1

Level II study, 10 Level III studies, and 3 Level IV studies).

Intervention methods were categorized as incorporating ei-

ther peers with ADHD or peers without ADHD. The methods

incorporating peers without ADHD were subcategorized as

play-based and school-based interventions. Study partici-

pants ranged in age from 5 to 16 yr, with most being between

ages 5 and 11 yr. The participants with ADHD were pre-

dominantly male, which is reflective of the population of

children with an ADHD diagnosis. In the

case of peers, more equal numbers of male

and female peers were common, and

some samples had more girls. Dosage for

the interventions ranged from one to five

times per week, for 20 min to 9 hr in each

session, over 12 days to 15 wk.

Interventions were evaluated individu-

ally to see how they affected social skills in

children with ADHD. Eleven studies pro-

duced statistically significant improvement

in social skills with peer involvement,

whereas four studies did not. Table 2 lists

the methods, peer roles, and settings used

for the interventions.

Risk of Bias We used Higgins et al.’s (2011) methods to

assess for risk of five types of bias: selection

bias, performance bias, detection bias,

attrition bias, and reporting bias (Table

A.2). Blinding of outcome assessment for

objective outcomes occurred in 7 of the 15

studies reviewed. Six studies had high risk

for attrition bias because of incomplete

outcome data. None of the studies had

high risk of selective reporting bias.

Avoiding most of these types of bias is often

impractical and problematic in studies with

Level II–IV designs. In spite of these risks,

we deemed the findings useful and valuable

to inform the use of interventions to sup-

port the social skills development of children with ADHD. Several researchers participated in multiple studies included

in this systematic review, although different participants were included in each of the studies.

Interventions Incorporating Peers Without Attention Deficit Hyperactivity Disorder Of the 15 articles, 11 involved interventions incorporating peers without ADHD. We classified these studies into two

subcategories: play-based interventions and school-based interventions.

Play-Based Interventions

Evidence from eight studies supports play-based interventions incorporating peers without ADHD. In a Level I study,

Wilkes-Gillan, Bundy, Cordier, Lincoln, and Chen (2016) used an intervention-first group and a control-first group to

evaluate a 10-wk play-based program. Children with ADHD were paired with a TD peer playmate and participated in

sessions involving video feedback, discussion of social skills, cooperative play, and therapist modeling. Parents joined

video feedback sessions, participated in discussions with

their children, observed play sessions, received training,

and delivered home modules weekly. Parents also facili-

tated four 40-min play sessions in their homes between a TD

playmate and their child with ADHD. The change in the

overall play skills of the intervention-first group after the

intervention phase was significantly greater than the change

in the overall play skills of the control-first group, t(14) =

8.02, p < .001. Test of Playfulness (Bundy, 2004) scores on

play skills items improved significantly from pre- to post-

intervention and from preintervention to 1-mo follow-up in

the intervention-first group (p < .001). Social items scores

revealed significant improvement from pre- to post-

intervention and from preintervention to 1-mo follow-up

(p < .001) but no significant difference from postintervention

to 1-mo follow-up (p > .05).

Barnes et al. (2017) conducted a Level III study using a

play-based intervention involving both home and clinic

settings for children with ADHD, TD peer playmates, and

the children’s parents. Video recordings, parent surveys

(Parenting Relationship Questionnaire, Kamphaus &

Reynolds, 2006; Social Skills Improvement System,

Gresham & Elliott, 2008), and direct observation were used

to evaluate play. Improvement in social play skills was

sustained in the home environment but not in the clinical

environment, as demonstrated by an increasing trend with a

medium effect size (d = 0.68, p = .36). Parents reported

continued use of the activities after the initial intervention,

which may have influenced maintenance of improvement demonstrated by the follow-up scores.

Wilkes-Gillan, Bundy, Cordier, and Lincoln (2016) conducted a Level III study of a 7-wk, parent-delivered, play-

based intervention for children with ADHD and TD peer playmates. Parents received 1 hr of training, administered home

modules to promote social interactions, and provided feedback to their children before, during, and after facilitated

playdates. Parents observed and discussed three clinic sessions of therapist-supported free play and promotion of

prosocial behaviors. Social play skills of children with ADHD significantly improved from pre- to postintervention (p = .03)

and 1-mo follow-up (p = .02). Additionally, social play skills of TD playmates significantly improved from pre- to

postintervention (p = .02). The long-term effectiveness of the study was evaluated in a Level III 18-mo follow-up study

by Cantrill et al. (2015). Semistructured interviews with parents and play observations revealed that play skills for both

children with ADHD and TD playmates improved, but not significantly, from postintervention to 18-mo follow-up,

demonstrating maintenance of skills (p = .07).

Three Level III studies used a 7-wk, play-based intervention program in which a TD peer playmate of similar age was

paired with a child with ADHD (Cordier et al., 2013; Docking et al., 2013; Wilkes et al., 2011). The intervention occurred

in 40-min sessions once a week in a playroom and included video feedback–feedforward and modeled play by the

therapist, peer, and child, while parents received training and education on social skills through play. Significant

improvements in play were found for both children with ADHD and their TD playmates (p < .01), and all children with

ADHD significantly improved their play skills (p < .01), whether they had language difficulty (p = .002) or not (p = .007;

Docking et al., 2013; Wilkes et al., 2011). Cordier et al. (2013) discovered significantly improved mean overall posttest

scores for pragmatic language on two outcome measures (Pragmatic Protocol, p = .006; Structured Multidimensional

Assessment Profiles, p = .001). However, Docking et al. (2013) reported that communication and pragmatic language

abilities of children with ADHD did not significantly improve over the course of the intervention (p = .528).

A Level III study by Wilkes-Gillan et al. (2014) investigated the effects of the 7-wk, play-based intervention performed

by Wilkes et al. (2011) at 18-mo follow-up through parent interviews and a 30-min clinic play session with a TD peer

playmate. The children with ADHD maintained their gains 18 mo after the intervention.

School-Based Interventions

Evidence from 3 Level IV studies supports school-based interventions incorporating peers without ADHD. Davies and

Witte (2000) examined the effect of a self-monitoring and group contingency approach to address inappropriate

verbalizations in the classroom. Peers played the roles of collaborative partner, class member, and behavior monitor.

The intervention was implemented in a third-grade classroom for 30-min sessions in two intervention periods. Ten

students were removed from the group, and the children with ADHD were rematched with TD students. Baseline

assessments were completed before each intervention period. At the initial baseline assessment, the children with

ADHD made significantly more inappropriate verbalizations (p < .05) than their TD peers. At the second baseline

assessment, the difference was no longer significant, indicating that the peer intervention had equalized the number of

inappropriate verbalizations by both groups.

Plumer and Stoner (2005) used the Classwide Peer Tutoring (CWPT) approach and peer coaching to improve

positive social behaviors of 2 fourth-grade children and 1 third-grade child with ADHD. CWPT is a teaching strategy that

may be applied with an entire class of students. In this study, CWPT was implemented using student pairs who

alternated between the roles of tutor and tutee during spelling practice. A point-reward system of reinforcement was

used to reward good performance, and in-the-moment error correction was provided. For the children with ADHD, peers

played the roles of tutor, behavior coach, and behavior monitor. An intervention stage that used only CWPT was

implemented for 20–25 min 3 days/wk for approximately 10 wk. Students reviewed goals each day and assigned

performance ratings for each. The Peer Social Behavior Code of the Systematic Screening for Behavior Disorders

(Walker & Severson, 1992) was used to measure positive social behaviors. In the academic setting, the 3 participants

increased positive social behaviors by 84%, 84%, and 87%. Generalized effects of CWPT were not found for social-

setting behaviors. In the social setting, 2 children increased positive social behaviors by 28% and 21%; 1 student’s result

was an outlier. Once peer coaching was added to the CWPT in later phases, the 3 students’ mean positive social

behaviors increased from 32% to 62%, 47% to 75%, and 69% to 90%, respectively. Comparing performance when peer

coaching was added to the CWPT-only phase suggests that peer coaching improved student outcomes in social

settings relative to CWPT alone. When using the Attention Scale of the Behavior Assessment System for Children

(Reynolds & Kamphaus, 1992) to address behavior and emotional qualities, the teacher reported improvements of

varying amounts in all 3 students.

Watkins and Wentzel (2008) examined the difference that involvement of a peer partner as a facilitator during a

planning task would make regarding social participation dynamics and problem-solving methods of children with ADHD.

Each child was provided with a shopping list and asked to plan possible routes through an imaginary town to the stores

needed to obtain the items in 25 min. Several days after the pretest, the children repeated the same task with a trained

peer partner without a time limit. Systematic observational coding of eight target behaviors during the collaborative

sessions indicated that the participants significantly increased joint participation (p < .01, d = 0.70) and collaborative

(p < .01, d = 0.60) behaviors and decreased dominance behaviors (p < .01, d = 0.83).

Interventions Incorporating Peers With Attention Deficit Hyperactivity Disorder Four studies assessed the influence of social skills interventions involving interactions with peers with ADHD in a group

therapy setting. In a Level II study, Frankel et al. (1997) explored the efficacy of a social skills training intervention that

involved role-play and coached play with a peer. Compared with the wait-list control group, the intervention group had

significantly better scores on the teacher-reported Aggression scale of the Pupil Evaluation Inventory (PEI; p < .05;

Pekarik et al., 1976) and the parent-reported Assertion and Self-Control subscales of the Social Skills Rating System

(SSRS; p < .05; Gresham & Elliott, 1990). No significant difference was found between groups in performance on the

Hyperactivity and Inattention scales of the PEI (p > .25).

In a Level III study, Corkum et al. (2010) examined the effectiveness of the Working Together Program, which

focuses on a range of social skills including making conversation, giving introductions, making positive statements to

others, speaking assertively, using courtesy words, asking for help, offering and giving help, giving and accepting

criticism, joining a play activity, and negotiating conflict. The intervention included role-play and group activities with

peers that targeted the social skills. Parent and teacher ratings of overall social skills on the SSRS improved significantly

(ps = .05 and .04, respectively). Student self-ratings at posttreatment were slightly higher than at pretreatment but did

not reach statistical significance.

Hoza et al. (2003) conducted a Level III study of the effects of a summer treatment program that consisted of a

behavioral point system, peer-oriented interventions, dyadic peer interventions, sports skills training, academic re-

mediation, participation in recreational activities, and weekly parent trainings. Each child was paired with a buddy to

promote friendship skills while participating in program activities. The buddy’s antisocial behavior was significantly

predictive of the children’s academic improvement and normalization. Children paired with a less antisocial buddy were

viewed as more normalized (p < .001), showed more improvement in academic performance, and had higher quality

friendships (p < .001). Parental compliance with the buddy system was predictive of the children’s perception of

companionship (p < .001) and was marginally predictive of positive adaptation (p < .10).

In a Level III study, Hansen et al. (2000) examined the Kids Together program, which uses play therapy, role-playing,

board games, and expressive arts to enhance social skills in a group therapy setting. Children practiced emotion

identification, nonverbal communication, self-image and others’ perceptions of them, self-monitoring and organization,

impulse control, conflict resolution, and responsibility with their peers. After the intervention, the children demonstrated

significant improvements in internalizing behavior problems (p = .008) and total behavior problems (p = .011). Ex-

ternalizing behaviors decreased, but not significantly (p = .051).

Discussion The purpose of this systematic review was to investigate existing evidence for the benefits of incorporating peer

interactions into interventions promoting social skills attainment in children with ADHD. Fifteen articles explored social

skills interventions incorporating TD peers or peers with ADHD. The children with ADHD who were paired with TD

peers showed more consistent and significant improvement in social play skills, pragmatic language, and problem

solving postintervention. Follow-up performance assessments in 5 studies indicated that children maintained im-

provements in social skills but did not demonstrate further improvement (Barnes et al., 2017; Cantrill et al., 2015;

Wilkes-Gillan et al., 2014; Wilkes-Gillan, Bundy, Cordier, & Lincoln, 2016; Wilkes-Gillan, Bundy, Cordier, Lincoln, &

Chen, 2016). However, none of the studies incorporating peers without ADHD included a follow-up assessment past

18 mo, so the long-term impact of the interventions cannot be generalized. Interventions involving peers with ADHD

focused on improving a variety of social skills in addition to reducing negative behaviors.

The considerable adult (e.g., parent, teacher, therapist) involvement in the social skills interventions of these studies

requires further discussion. The extent to which the social skills improvements can be attributed to the incorporation of

peers when adults were also part of the intervention (albeit in a different role from that of peers) is unknown. However, a

Research Article

systematic review by Storebø et al. (2019) of 25 randomized clinical trials on social skills training for children with ADHD

found no significant differences between groups that participated in social skills training and groups that received no

intervention. In that review, social skills training focused on teaching the children how to read subtle cues in social

interactions, typically with parents and teachers. Storebø et al. found that interventions primarily using parents and

teachers, rather than peers, had no significant effects on outcomes, unlike the results from studies in our review, in

which incorporating peers in the interventions produced significant improvements in most cases.

Overall, study outcomes provide moderate evidence supporting the use of social skills interventions for children with

ADHD that incorporate peers both with and without ADHD to increase play skills, reduce undesirable social behaviors,

and improve communication and social participation. The findings of this systematic review can be used in practice to

improve social skills development and ultimately social participation by children with ADHD. Occupational therapy

practitioners can use these findings to support inclusion of peers in the intervention process across multiple settings and

in a variety of roles. Regardless of intervention modalities used, studies incorporating peers were effective at improving

social skills of the children with ADHD. Targeting behaviors in the natural environment can help efforts made in therapy

generalize beyond the intervention and promote further improvements in play skills with repetition after intervention has

ceased. Improved outcomes and generalizability of skills across environments resulting from teaching and involving

parents during the intervention process were an additional practical implication of this review. However, it is important to

note that the lack of high-level studies addressing this topic limits understanding of the role that peer inclusion plays in

occupational therapy practice and how it can be used to promote generalization of social skills learned in therapy.

Strengths and Limitations Strengths of the 15 studies include statistically significant improvements after implementation of a social skills in-

tervention and promotion of interactions with peers. In addition, a majority of the studies (9 of 15) used multiple outcome

measures, providing more data to qualify results. Involvement of parents during the intervention process demonstrated

a positive influence on outcomes and increased generalizability of skills across environments. Finally, 5 studies

reported maintenance of improvements at follow-ups of previously conducted intervention studies, suggesting that

children with ADHD were able to maintain improved skills over time, even though outcomes were not always sig-

nificantly different between postintervention and follow-up assessments.

Limitations across the 15 studies included the lack of a control group (13 studies), participant dropout (6 studies),

lack of blinding of researchers scoring assessments (7 studies), small sample sizes and limited generalizability to

pediatric populations (5 studies), and insufficient evidence regarding generalizability of skills across environments and

long-term outcomes. In addition, discussion was limited regarding medication use and its effects on children’s social

interactions during interventions. Only 1 study demonstrated Level I evidence; the remaining 14 studies provided lower

evidence because randomized groups were not used, indicating that groups were not blinded to intervention, which

may have influenced performance outcomes. Finally, many studies had small sample sizes (<20 total participants).

The primary limitation of this review is that the studies did not always use peers as the primary intervention. Many

modalities were used in addition to peer involvement, making it difficult to clearly identify the incorporation of peers as

the reason for improvements in social skills. Additionally, peers were often siblings or of the opposite gender, possibly

resulting in different social expectations for the interactions. Inclusion only of studies available in English and published

in peer-reviewed journals was a limitation of the study selection process.

Future Research Further research is needed to provide additional support for incorporating peers in social skills interventions for children

with ADHD. Higher level studies are needed that strive to create specific intervention guidelines and that include control

groups, blinding of researchers, randomization of participants, and larger sample sizes. Future research should also

include longitudinal studies to track long-term outcomes.

Implications for Occupational Therapy Practice Our findings from the 15 studies indicate that social skills interventions incorporating the use of peers are beneficial for

children with ADHD, and in some cases their TD peers as well. The findings suggest the following implications for

occupational therapy practice:

• Social skills interventions incorporating the use of peers with or without ADHD are feasible and have the potential to

be an effective method for improving social interactions for children with ADHD.

• Play-based and school-based interventions that incorporate TD peers can help improve social skills of children with

ADHD.

• Social skills interventions combining multiple modalities—for example, parent involvement, video feedback, and

play—in addition to incorporating peers have the potential to result in greater improvements in social behaviors for

children with ADHD than one intervention method alone.

Conclusion Research has demonstrated that social skills interventions incorporating peers for children with ADHD can contribute to

improved social interactions and participation across multiple environments. Social skills interventions involving multiple

modalities that incorporate peers in various roles can result in improvements in social behaviors for children with

ADHD. It is important to practice social skills in natural environments to generalize skills across different contexts.

Educating parents and caregivers about supportive strategies and appropriate play can help children generalize skills to

the home environment. More research is needed to demonstrate the long-term effectiveness of interventions in-

corporating peers and generalization across environments.
