Inquiry 3 reports due Th 11/19 or M 11/23 The Biology of Human Interactions, a Strong Inference Refresher

The nervous system allows us to perceive the environment while the brain integrates the incoming signals to determine an appropriate response.

Input to brain is filtered. What are you paying attention to?

Active seeking of info versus Subconscious scanning for threats Are humans better at detecting threats?

Coalition Membership I like orange. Hook em’. I like to wear overalls. Gig em’. Go Aggies. I like to wear chaps. I like Maroon. Go Horns. Can race be erased? Coalitional computation and social categorization (December 18, 2001) PNAS vol. 98 no. 26 pg 15387–15392

When alternate coalition membership information is introduced, race is ignored. I like orange. Hook em’. I like to wear overalls. Gig em’. Go Aggies. I like to wear chaps. I like Maroon. Go Horns.

Despite a lifetime's experience of race as a predictor of social alliance, less than 4 min of exposure to an alternate social world was enough to deflate the tendency to categorize by race. These results suggest that racism may be a volatile and eradicable construct that persists only so long as it is actively maintained through being linked to parallel systems of social alliance.
