Barton and Cherkasova (2005) tested within-object and between-object spatial abilities of patients with prosopagnosia and concluded that prosopagnosia is the result of within-object spatial impairment. The interpretation of these findings is difficult as Barton and Cherkasova's (2005) experimental design involved a major confound of using smaller distances in the within-object task and larger distances in the between-object task. The present study used the same distances on between-object and within-object spatial discrimination tasks in an attempt to replicate the findings of Barton and Cherkasova (2005). Experiments 1 and 2 were designed to test within-object and between-object spatial processing of faces and objects, respectively, in prosopagnosia using the between-object spatial distances from Barton and Cherkasova (2005) while Experiments 3 and 4 tested these impairments using the within-object spatial distances from the original study. The experiments failed to find a difference in between-object and within-object spatial processing in a prosopagnosic.
