selective attention
(its divided into 2 parts, we only pay attention to 1 thing)
inattention blindness
def? ex?
this stimulus is usually unexpected but fully visible

REM sleep does increases after stressful events
ex: Rats in a maze (trained maze, 1 w/ full sleep remembered maze, other woken during REM did not)
Physiological function theories
-Activation-Synthesis Theory
- during night our brainstem releases random neural activity, dreams may be a way to make sense of that activity
- more limbic system and less frontal lobe… Freud would be happy (has to do w/ id)
REM rebound
tendency for REM sleep to increase following REM sleep deprivation
don’t get good night of sleep for a week & then sleep for 10 hrs
Sleep apnea
