ABSTRACT
This paper discusses the organisational and activational effects of sex hormones, and their influence on cognitive functioning. Previous studies have shown gender differences in specific cognitive abilities. Women generally show an advantage in verbal fluency, perceptual speed and accuracy, as well as in fine motor skills, while men generally show an advantage in spatial and mathematical abilities. These differences in cognitive functioning are thought to occur as a result of foetal brain exposure to different levels of sex hormones during prenatal life. Additional evidence of organisational effects of sex hormones on cognitive functioning also comes from studies of subjects with genetic disorders, such as androgen insensitivity syndrome, congenital adrenal hyperplasia, and Tyrner syndrome.Furthermore, former investigations have shown that increase in female sex hormone in the late follicular and/or luteal phase of the menstrual cycle intensifies the typical female cognitive pattern of functioning with improved efficiency in tasks which are usually better performed by women. At the same time, low levels of such hormones that characterise the menstrual phase of the cycle intensify the typical male cognitive pattern of functioning with better efficiency in tasks which usually better performed by men.This paper also points to methodological differences between investigations of organizational and activational effects of sex hormones on cognitive functioning, as well a to the direction of future investigations.
