The Role Of Androgens In Life History Theories Of Attachment, Janani S. Sankar
The Role Of Androgens In Life History Theories Of Attachment, Janani S. Sankar
Electronic Thesis and Dissertation Repository
Life history theories (LHTs) of attachment address how attachments to caregivers in infancy/childhood and to romantic partners in adulthood are used to negotiate mating and reproductive choices. Greater insecure-avoidant attachment has been suggested to be associated with the adoption of a low-investment, short-term reproductive strategy. The role of sex hormones, including the androgen testosterone (T), in the development of attachment-related reproductive strategies has been speculated in some LHTs. This research tested an integrated-LHT model of early environment, attachment, and reproductive strategies in men, using structural equation modeling. Androgen-related effects were hypothesized to occur prenatally and/or in adulthood, consistent with various …
Sexual Differentiation Of The Prefrontal Cortex In Humans: Examining Behavioural Sex Differences And The Modulatory Role Of Androgens, Kelly L. Evans
Sexual Differentiation Of The Prefrontal Cortex In Humans: Examining Behavioural Sex Differences And The Modulatory Role Of Androgens, Kelly L. Evans
Electronic Thesis and Dissertation Repository
Sex hormones are important factors in the establishment of sex differences in the brain and behaviour during the prenatal developmental period and during adulthood. One brain area that has received little attention with respect to the study of sex differences is the prefrontal cortex (PFC). The PFC is involved in cognitive functions not limited to working memory, reinforcement learning, and inhibitory control. Currently, our understanding of the hormonal modulation of the PFC by sex steroids is also limited. The overall objectives of the present thesis were: to test the hypothesis that select cognitive functions known to depend on the PFC …
