Autobiographical memory and perceptual learning: A developmental study using picture recognition,naming latency,and perceptual identification

Memory &; Cognition - In this paper, we report four experiments aimed at extending the distinction between recognition memory and perceptual memory introduced by Jacoby and Dallas (1981). In...     

Generalized imitation within three response classes in typically developing infants

Effects of modeling and contingent praise on infant imitation of three different responses was analyzed. Generalization to nonreinforced probe models was assessed both within and across response types. Three 12- to 14-month-old infants and their mothers participated in this study. During baseline the mothers provided models only. During treatment mothers modeled and also praised contingent upon infant matching of the training models. During interspersed probe trials the mothers modeled different responses, which, if matched by the infant, produced no praise. The three responses modeled were motor-with-toy, motor-without-toy, and vocal responses. The dependent measure was the percentage of maternal models that were matched by the infant within 6 s. Nonmatching responses of the same response type were also measured. Results showed a systematic increase in the percentages of training and probe models matched by the three infants following the introduction of the model-and-praise treatment condition. Nonmatching responses did not systematically increase. Thus, imitation generalized within response class, but not across response classes.     

Societal rule evaluations: Adolescent offenders' reasoning about moral,conventional, and personal rules

This study investigated adolescent offenders' (81 felons and 83 misdemeanants) evaluations of three types of societal rules (moral, conventional, and personal) on dimensions pertaining to importance, sanctions, authority, and individual choice. In addition, participants selected the acts which should be under personal jurisdiction. Participants provided reasons (i.e., justifications) to support their evaluations. The judgment evidence suggests that the moral rules were considered the most important, the transgressions the most wrong, the violators the most deserving of punishment, and the acts the least acceptable when permitted by an authority. With regard to these same dimensions, conventional rules and violations were ranked second; whereas, the personal rules were ranked third. Offender status differences were obtained for importance ratings and for deservedness of punishment. Justifications for moral events reflected reasoning from both the moral (e.g., other's welfare) and conventional (e.g., social order) domains. Reasoning about conventions involved both conventional and personal concerns; whereas, justifications about personal issues focused on individual prerogatives. The implications of these data are discussed. © 1996 Wiley-Liss, Inc.
