What is the dual processing being revealed by today's cognitive neuroscience?
|
1. They stud the brain mechanisms underlying consciousness and cognition
2. They have discovered the two track mind, with each side having its own neural processing. 3. The difference affects our perception, memory and attitudes at an explicit and implicit level. |
|
|
How much information do we consciously attend to at once?
|
1. We selectively tend, blocking out most
2. We even display intentional blindness |
|
|
How do our biological rhythms influence our daily functioning and our sleep and dreams?
|
1. They create periodic psychological fluctuations (circadian rhythm)
|
|
|
What is the biological rhythm of our sleep?
|
Relaxed Alpha waves
1. sleep with physical sensation (20mins) 2. has sleep spindles 3.+4. slow delta waves (together last 30 mins) 5. REM -inward arousal, outward paralysis longer one sleeps the longer the REM sleep lasts (dreams) |
|
|
How does sleep loss effect us?
|
1. fatigue
2. impairs concentration, creativity, and communication |
|
|
What's sleep's function?
|
1. Evolutionarily, keeping people safe from potentially dangerous periods
2. gives brains time to heal (neurons repair) 3. stores and rebuilds memories 4. promotes good problem solving 5. encourages growth with pituitary gland secretions. |
|
|
What are the major sleep disorders?
|
1. insomnia
2. narcolepsy 3. sleep apnea 4. night terrors 5. sleepwalking and talking |
|
|
What do we dream?
|
1. Dream of ordinary events, most involving anxiety and misfortune
2. less than 10% of women dream with sexual content 3. occur during REM sleep |
|
|
What is the function of dreams?
|
1. Freudian: to provide safe valve with a censored storyline covering latent content
2. information processing to sort out and fix problems 3. brain stimulation to sustain neural pathways 4. activation-synthesis explanation, to make sense of neural static our brain tries to weave into a storyline 5. brain maturation- represent dreamers level of development, etc 6. REM rebound |
