Content-specific activational effects of estrogen on working memory performance
This study aimed at exploring the influence of the task content and the menstrual cycle phase on working memory (WM) performance. The content-specificity of WM was addressed within the framework of evolutionary psychology, proposing a hormone-mediated adaptive design governing face perception. Two groups of healthy young women (n=66 regular menstrual cycle, and n=27 on oral contraceptives users) were tested on a WM task with adult male or infant face photographs. ANOVA showed significant interaction between task content and estrogen level: women were more efficient in solving the male faces task during high- compared to low-estrogen phase of the cycle. No differences were found in the efficacy of solving the infant faces task between different phases of the cycle. Results suggest content-specific activational effects of estrogen on the WM performance and are consistent with the notion of a hormonal mechanism underlying adaptive shifts in cognition related to the mating motivation.
