Biological Approach

Techniques to study, Localization of function (Brain and Behavior), Neuroplasticity

Maguire et al: Taxi drivers, hippocampus. Hippocampi of taxi drivers were larger than control, Volume of right posterior hippocampi correlated with amount of time spent as driver. Hippocampus change in response to environmental demands.

Neuroplasticity (Brain and Behavior)

Draganski: New skill would affect brain. MRI scan as base rate. More gray matter in mid-temporal area in both hemispheres. After no longer preforming skill, grey matter decreased.

Neurotransmitter (Brain and behavior), hormones

Morhenn: Trust game, trust game and massage, massage, massage gave higher oxytocin and gave more money

Pheromones and behavior, genetic similarities

Wedekind: Wear shirt for 3 days then women sniffed. They liked shirts of those with different genes than themselves. Androstadiene.

Genetics and behavior

Heston: Adopted children were likely to have schizophrenia if bio mom had. 10% were diagnosed.

Evolutionary explanations for behaviors

Releigh et al: Relation between social status and serotonin (depression neurotransmitter). Observed monkeys. Loss of dominance cause symptoms.
