Document Summary

Start posting a discussion question for each class (due by 10am day of) use readings. Real world applications (these are worth 10% of your grade can miss 2 w/o penalty) **consider starting thought paper (worth 10%) one due before midterm, one due after. Organizational effects: hormone exposure early during development acts to organize the neural circuitry underlying behavior. May influence social behavior later in life (due to this prenatal exposure of testosterone) Second to forth digit ratio as an indirect marker of prenatal testosterone studies have measured fingers and their digit ratio but results are weak and inconsistent. (men generally have longer ring fingers) Activational effects: hormone concentrations later in life activate the organized brain to influence behavior (e. g. puberty) Example: measured aggressive behavior in economic game (high testosterone concentrations related to aggressive behavior) reduced activity (or deactivation) in orbitofrontal cortex (region associated with self-regulation and impulse control) Behavior and social environment can cause hormone levels to fluctuate within minutes.
