Limited data are available regarding the clinical utility of the Wechsler Memory Scale-III (WMS-III) Family Pictures (FP) subtest, yet it has received much criticism in the literature. Specific problems of the subtest that have been cited include the lack of clarity regarding the neuropsychological functions that significantly influence successful performance. The current study assesses the extent to which performance on the FP I and FP II subtests can be predicted by memory, visual ability, verbal ability, and executive functioning, in 454 outpatients from a neuropsychology clinic. Data from the Family Pictures I (FPI) and Family Pictures II (FPII) subtests, in addition to scores obtained from commonly used measures of memory, verbal, visual, and executive functioning were analyzed via hierarchical multiple regression analyses, co-varying for age and education. The current study also explores the extent to which the FP's individual components of character, location, and action load on factors of general verbal and visual-spatial abilities in a sample of 193 neuropsychology clinic outpatients. Results were obtained via three separate exploratory factor analyses (one for each FP component examined). Results of the multiple regression analyses indicated that FP I and FP II performance is best predicted by a mixed visual/verbal memory factor. Furthermore, the factor analyses revealed that all three components of location, action, and character load on a mixed general visual ability and general memory factor. These findings expand upon previous research by lending greater understanding of the skills needed for successful FP performance in neuropsychologically impaired populations.

The Wechsler Memory Scale –iii is the newest version of a six-decade old neuropsychological inventory. Since its conception, the Wechsler Memory Scale has been highly utilized by practitioners to accurately assess various memory functions in adult subjects. Revisions made within this inventory include the Faces I subtest, a facial recognition scale, which was added in order to strengthen the instrument’s accuracy at measuring episodic memory. Facial recognition, both cross-race and within-race, has been researched extensively and consistent biases have been found between race of test taker and cross-racial identification. Theories of exposure/contextual interaction (environment) and biological foundations have been the subject of study in the past in order to determine from where these racial identification deficits stem. The current study focuses on revealing bias in the Faces I subtest, regarding to an unequal distribution of racially representative faces in the testing materials. Eighty-eight college students were recruited to view forty-eight pictured faces from the Faces I subtest and determine the racial category to which the pictured face belonged. The subjects’ categorical responses were the basis for calculating a percent agreement score for racial category of each face. It was determined, using the results of subjects’ responses, that the Faces I subtest contained an unequal distribution of racially representative faces in both the Target and Interference testing material. This confirmed the presence of an inherent bias within the subscale. The implications of memory accuracy for the WMS-iii are discussed as it relates to different fields of study, but none more directly than the criminal justice system. Eyewitness testimony is a pivotal evidentiary tool in the criminal justice system, and ramifications of cross-racial identification deficits and biases in the tools to accurately assess memory are increasingly bringing this once heavily relied upon tool into question.
