Selective Attention |
Driving cars with cell phones uses selective attention, we constantly switch from cell phone to driving/data that cell phone is more distractive that even talking with person in a the car. |
|
|
Selective Innatention |
We we are "blind" to. Magicians use this trick; cause us to concentrate on another aspect, while a change is made. |
|
|
Circadian Rhythm |
24 hr sleep/awake cycle Changes in temperature Taking medications |
|
|
Pineal Gland |
Produces melatonin, which helps people sleep. It is higher in the evening time. |
|
|
Rapid Eye Movement (REM) sleep |
fast, jerky eye movements; associated with dreaming |
|
|
Stages of sleep |
-Alpha waves - awake but relaxed state/in bed but not asleep -Sleep vs wake : sleep is measured in slow breathing/irregular brain patterns. - Stage 1: associated with hallucinations/out of body experiences - Stage 2: more relaxed, slower HR - Stage 3&4 - Deep sleep/Delta waves, hard to wake patients - Sage 5 - REM and dreaming |
|
|
REM Sleep |
REM priods increase as night progreses REM= Higher heart rate, rapid/irregular breathing, genitals become aroused Need for REM is biological, REM rebound if one is deprived of sleep |
|
|
Characteristics of Sleep |
Newborns: asleep 2/3 or time Adults: 1/3 of time Sleep: inc memory, concentration, mood, inc hunger, promotes immunity Repair/Restore neuronal tissue Making memory enhances creativity |
|
|
Insomnia |
Persistent problem sleeping - Sleeping Pills and Alcohol Often exacerbate sleeping problems |
|
|
Narcolepsy |
Overwhelming sleepiness, occur at unexpected times, genetic link |
|
|
Sleep apnea |
stop breathing during sleep. Often unaware of disorder associated with obesity |
|
|

Mostly in children, not dreams since they do not occur in REM sleep when dreaming happens. |
|
|
Freud and Dreams |

|

|
Depressant - Alcohol |
A. Alcohol -Disinhibition: Slowing brain activity and lowers control of judgement and inhibition Slows sympathetic nervous system Disrupts memory, supresses REM sleep Reduces awareness/supression of feeling of failure/shortcoming Correlated to risky sex |
|
|
More depressants |
Barbiturates (tranquilizers) - Mimic effect of alcohol, in combination w/ ETOH, can be deadly Opiates - opium, morphine, heroin; relaxes, short term pleasure, and causes brain to stop producing own opiates known as endorphins |
|
|
Stimulants |
Caffeine: most widely consumed in world. Withdrawal includes fatigue and headaches. Nicotine: Boosts alertness, inc heart rate/bp, relax muscles, reduces blood flow to arms and legs. |
|
|
More Stimulants |
Cocaine: Creates rush of euphoria, depletes brain supply of neurotransmitters. Ecstasy - triggers dopamine/seratonin release, flooding of "feel good" sensation. |
|
|
