Gender differences in event-related potentials elicited by visual stimuli of increasing stimulus complexity

Introduction: Cognitive processes are differentially affected with gender such that there is generally a female superiority in verbal functions and a male superiority in visuo-spatial functions (Kolb and Whishaw, 1996). The aim of this study was to investigate electrophysiological differences between females and males in processing visual stimuli of same task relevance, but different complexity. Methods: We examined 31 healthy subjects (15 f/16m), aged 25,7±4,4 years. ERP were elicited by black and white patterns (21×16 squares) of increasing complexity: 1) regular checkerboard, 2) irregular random pattern, and…
