Consciousness biological rhythms and sleep: learning objectives, define consciousness, des(cid:272)ri(cid:271)e willia(cid:373) ja(cid:373)es" (cid:448)ie(cid:449) of (cid:272)o(cid:374)s(cid:272)ious(cid:374)ess, describe mind wandering and selective attention, describe automatic and controlled processes, and provide examples, describe how consciousness is measured in the brain. Biological rhythms: learning objectives, describe circadian rhythms. 2: sleep/wake cycle determined by melatonin secretion (produced in the dark, body temperature cools before sleep, no fluctuations of light & dark = longer circadian rhythms (25hrs) Jet lag: clo(cid:272)k ti(cid:373)e (cid:272)ha(cid:374)ges, (cid:271)iologi(cid:272)al ti(cid:373)e does(cid:374)"t, symptoms, sleepiness.
