Description
Introduction: Previous research indicated that poor performance on some aspects of spatial ability is associated with Fragile X Syndrome (Cornish et al., 1998). Hocking et al. (2012) reported that males identified as FXS premutation carriers performed more poorly than males with normal FMR1 alleles on spatial processing tasks involving mental manipulation of shapes, and on visuospatial working memory. Females with FXS exhibited poor performance on some measures of memory for spatial location (Mazzocco et al., 2006). Our study investigated whether people with FXS also exhibit relatively poor performance in visual perspective taking (PT). Methods: Participants with FXS (n = 14) were matched on cognitive ability to typically developing (TD) counterparts (n = 14) using the Raven’s-2 Progressive Matrices (Raven et al., 2018). We administered two PT tasks: 1. Three Mountains Task (TMT) modeled after Newcombe and Huttenlocher (1992); 2. Dog Task (DT) modeled after Piaget and Inhelder (1956). Results: Groups did not differ on the DT (M = 17.36, SD = 5.72 for FXS and M = 18.50, SD = 4.36 for TD: F(26) = 0.59, p = .305, BF = 3.19). Groups also did not differ on the TMT (M = 15.79, SD = 4.81 for FXS and M = 16.00, SD = 4.77 for TD: F(26) = 0.12, p = .967, BF = 3.68). Implications: Both groups performed similarly on the PT tasks. Implications include informing future interventions relating to training spatial abilities that affect daily activities associated with independent living.
