Upper body strength and socioeconomic status can predict men’s opinions on the redistribution of wealth, according to researchers.

  • “Our results demonstrate that physically weak males are more reluctant than physically strong males to assert their self-interest—just as if disputes over national policies were a matter of direct physical confrontation among small numbers of individuals, rather than abstract electoral dynamics among millions,”

  • “This suggests that the human mind is ecologically rational and designed for small-scale societies rather than means-end rational. In short, within our modern skulls lies a brain designed for ancestral challenges.”

  • “Compared to males, ancestral human females derived fewer benefits and incurred higher costs when bargaining using physical aggression. Women can certainly be competitive, but they use more indirect forms of aggression.”

Foundational Work on “Emotions” in Fruit Flies

Standard

SUMMARY The neural circuit mechanisms underlying emotion states remain poorly understood. Drosophila offers powerful genetic approaches for dissecting neural circuit function, but whether flies exhibit emotion like behaviors has not been clear. We recently proposed that model organisms may express internal states displaying ‘‘emotion primitives,’’ which are general characteristics common to different emotions, rather than specific anthropomorphic emotions such as ‘‘fear’’ or ‘‘anxiety.’’ Continue reading

“Researchers at Northwestern University have determined that Wernicke’s area, a hotdog-shape region in the temporal lobe of the left hemisphere, may not be the seat of language comprehension, as has been scientific dogma for the past 140 years. Instead, the team suggests in a study published today (June 25) in the neurology journal Brain, understanding the meaning of words happens in the left anterior temporal lobe, while sentence comprehension is handled by a complex network of brain areas.”
