This study compared effects of inversion on perceptual processing of faces with distorted components (eyes and mouths) and faces distorted by altering spatial relations between components. In a rating task, participants inversion reduced the rated grotesqueness of spatially distorted faces but not that of faces with altered components. In a comparison task, pairs of faces were shown side by side; participants judged whether they were identical or different. Inversion greatly reduced the rate at which participants responded within 3 s to pairs that differed spatially, but not pairs that differed componentially. Also, latencies for detecting spatial differences were lengthened by inversion more than latencies for detecting componential differences. Results support the hypothesis that inversion impairs encoding of spatial-relational information more than, or instead of, componential information, depending on the task.

and AMINAMEMON University ofSouthampton, Southampton, EnglandStudies of aging and face recognition show age-related increases in false recognitions of new faces. Toexplore implications of this false alarm effect, we had young and senior adults perform (1) three eyewitness identification tasks, using both target present and target absent lineups, and (2) an old/new recognition task in which a study list of faces was followed by a test including old and new faces, along with conjunctions of old faces. Compared with the young, seniors had lower accuracy and higher choosing rates on the lineups, and they also falsely recognized more new faces on the recognition test. However, after screening for perceptual processing deficits, there was no age difference in false recognition of conjunctions, or in discriminating old faces from conjunctions. We conclude that the false alarm effect generalizes to lineup identification, but does not extend to conjunction faces. The findings are consistent with age-related deficits in recollection of context and relative age invariance in perceptual integrative processes underlying the experience of familiarity.

Young (18-30 years) and older (62-79 years) adults (N = 96) engaged in a 20-min live interaction with the future target in a lineup task. One month later, participants were interviewed about the events in the prior encounter (with or without context reinstatement), and then they saw a target-present (TP) or target-absent (TA) lineup. The lineup was followed by the Benton Face Recognition Test (A. Benton, A. Sivan, K. Hamsher, N. Varney, & O. Spreen, 1994), which correlated positively with accuracy in TP, especially for young adults. False identification in TA was associated with (a) higher scores on a memory self-efficacy scale and (b) higher recall of information about the initial event, although only for seniors. Results suggested that age-related increases in false identification generalize to ecologically valid conditions and that seniors' performance on lineups is negatively related to verbal recall as well as to self-reports of satisfactory experiences with memory in life.
