In this paper, the authors review empirical evidence on the effects of peer groups on social, emotional and behavioural functioning. The paper shows that an understanding of the ways in which peer groups can influence the development of deviance and subvert the positive effects of interventions can be exploited in the promotion of positive social and emotional functioning.The student peer group performs a powerful role influencing the quality of student behaviour in schools that, if not harnessed effectively, can have a negative impact. The main focus of this paper 1 is to examine some of the empirical evidence on the positive utilisation of peer influence in the classroom.
Peers as a negative classroom influenceThe possible negative impact of the peer group is illustrated in a study conducted by Barth et al. (2004). They studied 65 classrooms in 17 schools with a high proportion of SEBD and found that disruptive students served to promote negative behaviours, and that the classroom environment was counter-productive where these students served as role models. Dishion, McCord and Poulin (1999) showed how this negative influence has the capacity to undermine interventions designed to alleviate behavioural difficulties.This counter productive effect is illustrated in a retrospective study of two peer-oriented interventions for high-risk boys, conducted by Gottfredson (1987). Outcome measures appeared to point to the success of the interventions during the interventions; however, follow-up studies showed that both these interventions had been not only unsuccessful, but that the children who had taken part, both in the short and long term, were more likely than those in the control groups to indulge in the very high-risk behaviours which the programme had been targeting. This was particularly evident in the earlier intervention, which showed no differences in improvement between target and control group adolescents. Further, more worryingly, there appeared to be harmful long-term effects, especially on those who had been involved in the most intensive of the interventions when follow-up data about these participants were collected during their late middle age. The mechanism at work here is described as 'deviancy training', whereby the highlighting of deviant
