INTRODUCTION: Visuospatial abilities encompass the perception, representation, and manipulation of spatial relationships and constitute a core domain of cognitive functioning. Although cognitive aging is well documented, the pattern of age-related changes across specific visuospatial components in healthy adults remains insufficiently defined.
AIM(S): This study aimed to provide a quantitative characterization of selected visuospatial processes and to examine their associations with age.
METHOD(S): Fifty-eight neurologically and psychiatrically healthy adults completed measures of visual search (Test of Attention and Perceptiveness; Color Trails Test 1 and 2), mental rotation (Mental Rotation Test – Version A), spatial perception (Line Orientation Recognition task), and spatial visualization (Block Design, WAIS-IV). Accuracy and completion time indices were analyzed using Spearman’s rho correlations.
RESULTS: Age was moderately and negatively associated with performance accuracy in mental rotation (rho = −0.35, p < .05) and spatial perception (rho = −0.31, p < .05), indicating increased error rates with advancing age. No significant association was observed between age and completion time in visual search tasks.
CONCLUSIONS: These findings suggest that normative aging is characterized by greater vulnerability of processes requiring manipulation and discrimination of spatial relationships, whereas processing speed in visual search appears relatively preserved. The pattern supports partial selectivity of age-related changes rather than uniform visuospatial decline. The results provide a reference framework for differentiating normative aging from pathological visuospatial impairment in clinical assessment.
