Document Summary
Perhaps food is eaten or digested faster if the body is physiologically prepared. Subjects drinking an unfamiliar drink (green peppermint) will show stronger intoxication than subjects drinking a familiar drink (favourite beer). Subjective intoxication: tracking a rapidly moving circle with a mouse, word search in a 16x16 grid of jumbled letters. Subjects associate familiar cues w/ anticipated negative effects & take (unconscious) physiological measures to counteract such effects. Learning helps animals to anticipate & prepare to body for events w/ strong physiological impacts. Suppose your friend drinks coffee occasionally. Caffeine causes the constriction of blood vessels in the brain. Physiological adaptation to caffeine = relaxation of cerebral blood vessels to counteract caffeine"s effect. Skipping your regular morning coffee = headache. Suppose your mistakenly have a decaf coffee in your regular mug & at your regular morning coffee time. There"s either no or limited social learning in many species. Individuals don"t learn from others. Social learning is important where it occurs.
