Document Summary

Lecture 10: 6 ways in which fear and anxiety can benefit and protect individuals, responses to fear: Release of epinephrine (adrenalin) from adrenal glands: aids in blood clotting. Some genes improve fitness early but have consequences later. Human evolutionary psychology and animal behaviour: evolutionary psychology is described as evolutionary informed study of human mental processes, taxonomic restriction is inappropriate for 4 reasons: Long and honorable tradition of cross-species comparison within psychology. Erecting subdisciplinary boundaries along species lines hinders the diffusion of latest evolutionary thinking into the human sciences. Even within hep, best work is conducted by animal behaviorists that treat humans like any other anima: efforts to integrate study of human psychology and behaviour into darwinian framework as hep. Goal of study: assess how common this feature is among invertebrates, estimate the fitness vvalue of anxiety. Results: enhanced prolonged sheltering in response to increasing number of electric shocks, fitness benefit, increased survval to predation risk.
