A large percentage of people recently exonerated by DNA evidence were imprisoned on the basis of faulty eyewitness identification. Many of these cases involved victims and suspects of different races. Two studies examined the recognition of Hispanic and Black target faces by Hispanic participants under nonoptimal viewing conditions. When viewing time decreased, recognition performance for same-and other-race faces systematically shifted downward. Recognition accuracy for faces of both races decreased under conditions of high negative arousal and attention load; however, recognition of same-race faces was differentially affected by attention distractors. Face recognition accuracy was not affected by a delay between initial presentation of the faces and the face recognition test. An understanding of how recognition of other-race persons differs from that of same-race persons can assist by reducing misidentifications and ensuring that the perpetrator rather than an innocent person is imprisoned.

A model of social perception is presented and tested. The model is based on cognitive neuroscience models and proposes that the right cerebral hemisphere is more efficient at processing combinations of features whereas the left hemisphere is superior at identifying single features. These processes are hypothesized to produce person and group-based representations, respectively. Individuating or personalizing experience with an outgroup member was expected to facilitate the perception of the individuating features and inhibit the perception of the group features. In the presented study, participants were asked to learn about various ingroup and outgroup targets. Later, participants demonstrated that categorization response speeds to old targets were slower in the left hemisphere than in the right, particularly for outgroup members, as predicted. These findings are discussed for their relevance to models of social perception and stereotyping.

The present study is an examination of the perception of guilt based on the number of aliases used by a defendant. Participants in Experiment 1 (N = 275) reviewed materials summarizing an actual crime in which the defendant was identified with no alias information or with 1, 5, or 9 aliases. Participants were asked to decide if the suspect was guilty and if so, what his sentence should be. Results showed that the presence of alias information influenced perceptions of guilt. However, in conditions where the defendant had more aliases, the maximum sentence was imposed less often. Relationship information linking the suspect and the victim in the materials was removed for some of the participants in Experiment 2. Participants (N = 265) were provided with either no alias information or all 9 aliases. An interaction was found in Experiment 2 demonstrating the alias advantage only when the relationship information was present. However, the relationship information had minimal effect on the attributions made toward the victim.
