The conversations of 186 adolescent boys (13 to 14 years old) and thei
r friends were videotaped and analyzed to understand the processes of
influence associated with antisocial behavior. The videotaped discussi
ons were coded with a system that captured the general topics (Normati
ve vs. Rule-Breaking) as well as the reactions of the listener (Laugh
vs. Pause). Matching law analyses confirmed a linear relationship betw
een the dyadic rate of Rule-Breaking talk and contingent positive reac
tions. Sequential analyses revealed a statistically reliable reciproca
l pattern between Rule-Breaking talk and Laugh in the delinquent (both
boys arrested) dyads, whereas in the mixed (one arrested) and nondeli
nquent (neither arrested) dyads, reciprocation occurred between Normat
ive talk and Laugh. Longitudinal analyses of the boys' behavior over t
he ensuing 2 years revealed that the deviancy training sequence was pr
ognostic of increases in self-reported delinquent behavior, even after
controlling for prior levels of delinquency. It appears that discussi
ons of deviancy play a critical role in organizing positive affective
exchanges, thereby establishing problem behavior as a common ground ac
tivity that potentially exacerbates adolescent social maladjustment. T
hese findings are discussed with respect to developmental theory and i
ntervention science.
