Gender Differences in Risk-proneness, Gratification Delay, Self-control, Self-efficacy, Executive Functions and Their Neurophysiological and Neuroanatomical Correlates in Early Adolescents
Risk-taking in early adolescence have has been found to be normative and even formative as it
might fulfill the youth's needs to experiment different sensations, make independent
decisions and learn from their consequences. Several theoretical models have suggested that
male and female adolescents differ in risk-taking as a product of individual/contextual
factors and neocortical functioning; however, the neurophysiological and neuropsychological
correlates of those differences continue to be underexplored. Informed by Evolutionary
Neuroandrogenic Theory, the investigators examine the links between gender, risk-proneness,
gratification delay, self-control, self-efficacy, executive functions and
neurophysiological-neuroanatomical correlates in early adolescents (age 10-12 years).
Participants (N=24; 50% females) will complete behavioral measurements on study constructs
and perform neuropsychological tests using fMRI scanning (e.g., Go/NoGo continuous
performance, stop-signal reaction time, NIH Cognition Battery, delay discounting). Female and
male groups will be compared on all outcome measures.
