This study examined the relationship between time of exposure to the human face and accurate subsequent photo line-up identification. A volunteer group of 124 undergraduate students was divided into three approximately equal sized subgroups. The three groups were then exposed to a video or a portion of a video depicting a theft. Exposure times ranged from two minutes to 30 seconds. The subjects were then given a questionnaire and shown a photo line-up of the mock perpetrator and five foils. Subjects were asked to identify the perpetrator and mark that identification on the questionnaire. Results of the experiment indicated that the longer a subject was exposed the greater the possibility of an accurate identification.

The problems that gang members create within adult correctional facilities continue to receive attention in the literature. Gang members within juvenile institutions have received far less attention from researchers, and misconduct of these juveniles, both serious and non-serious, is relatively unexplored. This study explored the institutional misconduct of 4,309 male delinquents released from the Texas Youth Commission. Youths younger at commitment, those with a higher TYC risk score, and those youths with emotional problems were found more likely to commit both serious and non-serious institutional misconduct, regardless of gang membership. This thesis concludes with suggestions for additional research on gang members within juvenile institutions and the relationship of gang membership to institutional misconduct.
