Q

Naturalistic Observation

A

Strengths: only way to understand what individuals do day to day, don’t require much effort
weakness: behaviors occur infrequently, lots going on at once hard to determine influence on behavior and record action, time consuming, presence of observer changes behavior

Q

Structured Observation

A

Strength:test individual differences or patterns, increase the likelihood of obtaining behavior of interest
Weaknesses: participants know they’re being watched “real behavior?”

17
Q

genes/dna/chromosomes

A

gene: small segments of dan
dna: organized into 46 chromosomes
chromosomes: carries genetic info in the form of sense

18
Q

brain lateralization

A

some functions or cognitive processes tend to be more dominant in one hemisphere than the other

19
Q

corpus collosum

A

joins two hemispheres of the brain together

20
Q

occipital lobe

21
Q

parietal lobe

A

body sensations

22
Q

temporal lobe

23
Q

frontal lobe

A

planning, personality, attention

24
Q

Thallamus

A

“relay station” for most info going in and out

25
cerebellum
control movement/balance | organize sensory information, attention shifting, planning
26
medulla
vital reflexes (breathing, heart rate)
27
pons
bridge for nerves to cross brain
28
brainstem
connects cerebrum with spinal cord. motor and sensory neurons pass through
29
dendrite
receive information
30
axon
transmit information
31
myelin
insulates axons and speeds electrical transmission along axons
32
plasticity of the brain
area of brain injured, area of brain around it tries to pick up the function of the injured brain
33
how to prepare/get better sleep
make room dark, turn off electronic devices, no caffeine after lunch, light in the morning
34
effects of sleep deprivation
``` poorer memory emotional instability impaired decision making decreased leptin physical damage ```
35
consciousness
awareness of internal and external stimuli. Aware that experiences and thoughts of these experiences are unique to yourself
36
EEG
activity similar to stages when awake, although person is seemingly deeply sleeping
37
Circadian rhythm
24 hr biological cycles found in humans
38
REM sleep
irregular breathing and pulse, very relaxed muscles
39
effects of shift work
physical damage (cancer), sleep depervation, circadian rhythm
40
effects of mediation
heighten awareness, bring mental processes under voluntary control, suppression of bodily arousal
41
3 happy lives
pleasant life( as many pleasures as you can), the good life (pleasure vs flow), and the meaningful life (doing good)
