Psychology chap 4-6 Flashcards
Consciousness voluntary control; able to describe to others
Consciousness
Simultaneous without consciousness
Unconscious
Focus intently on ONE THING
Selective attention
Regular cycles of behavior
Biological rhythm
24 hour biological cycle of humans/many other species
Circadian rhythm
Seasonal affective disorder
One outcome
Falling asleep; slow alpha waves
Yawn
drowsy; theta waves
breathing, heart rate slow
muscle tension, body temperature decline
body “twitching”
N-1 (non-REM 1) (15 minutes)
“sleep spindles” ; clearly asleep
further decrease in muscle activit y
50% of nighttime sleep here
N-2 (non-REM 2) (30 minutes)
more transition; some dreaming (NOT the dream stage)
slow-wave sleep; large delta waves
sleepwalking, bedwetting, nightmares
can STILL process stimuli
N-3 (non-REM 3) (30 minutes)
REM Sleep rapid brain-wave activity
eyes dart; MAJOR DREAM
genital/vaginal arousal
muscles relax; not easily wakened
active limbic system/amygdala
REM Sleep
When does the cycle repeat?
every 90 minutes
Persistent difficulty falling OR staying asleep
Insomnia
Short periods of no breathing
Sleep apnea
Overwhelming sleepiness (not tied to time of day); genetic and neurologic reasons
Narcolepsy
Scared; recall nothing likely in REM
Sleep/night terrors
Why do we sleep?
Restore body tissue; builds immunity; sleep deprivation
Images, thoughts, sounds, emotions, while sleeping
Dreams
What do we dream?
Freud = “manifest content”
Day’s events, details
Why do we dream?
Freud = “latent content”
Hidden meaning (wishes, drives)
A chemical substance that alters perception and / or mood
Psychoactive Drug
The drugs absence results in physical pain and intense cravings
Physical dependence
Larger doses needed to achieve effect
Tolerance
Psychological need, especially for drugs that reduce stress
Psychological dependence
Negative reaction to reducing or stopping drug
Withdrawal
Compulsive drug craving and use
Addiction
__________ dependence is often harder to break than _______ dependence.
1) psychological
2) physical
SPEED UP CNS by blocking reuptake of dopamine, adrenaline, serotonin in synapses
Stimulants
Stimulant risk groups
Athletes, dieters, those desiring to stay awake
REDUCE activity of CNS
Depressants
Increase activity in certain receptor neurons in the brain and digestive system
Opioids
Most extreme alteration of consciousness; distort sensations and perceptions
Hallucinogens
Reducing stimuli to your five senses to alter consciousness
Sensory deprivation
Focuses on internal state of being
Meditation and relaxation
Erik Erikson
Interested in SOCIAL need to resolve goals and demands of each stage
Jean Piaget
Interested in COGNITIVE development - thinking
Lawrence Kohlberg
Interested in MORAL development
Fertilization of an egg by sperm; begins with ovulation
Conception
fertilized egg - conception to implantation
Zygote
Typically 2-8 weeks post-implantation
Embryo
8-40 weeks; grow, grow, grow
Fetus
Harmful agents
Terotagens
Neurons at work; “growth spurt” ; brain “plastic”
Brain development
stroke a babies cheek right after birth and they will move their head towards that side (looking for breast/bottle)
Rooting reflex
Lay a newborn down flat with their hands by their ears in tight fists; while you gently move their head to one side, their hand straightens out to the side
Tonic neck reflex
Startle response when someone picks a baby up because they are startled
Moro reflex
Mental activities associated with thinking and knowing
Cognition
“Concepts” of knowledge related to long-term memory
Schemas
Interpret experience through CURRENT schema that is already developed
Assimilation
Adjust to fit NEW information into an existing schema
Accommodation
(birth-2): coordinate senses and motor skills; no “object permanence” until - 8 months
Sensorimotor
(2-6): form mental images, but not abstract; egocentric
Preoperational
(7-11): concrete thought; more accurate concepts of time, space, numbers; still not adult logic
Concrete-operational
(12-on): abstract thought (imagination)
Formal operational
Personal knowledge worth (begins early)
Self-concept
Need for closeness to primary caregiver (body contact)
Attachment
No critical period or “imprinting” for humans
Familiarity
Capable of reproducing; hormonal changes that cause rapid physical change in the body
Puberty
Comfortable sense of “self”
Identity
Form emotionally close ties; needs identity FIRST
Intimacy
later independence, later marriage, later child-bearing
“not-yet-settled” phase of life
Weaker immune systems, but accumulate antibodies
Health
RECALL weakens; RECOGNITION intact
Memory
General knowledge (accumulate)
Crystallized intelligence
Ability to acquire information quickly abstractly (decrease)
Fluid intelligence
A relatively permanent change in behavior due to experience
Learning
We learn to associate stimuli
Classical conditioning
We learn to associate our action with stimuli
Operant conditioning
Learning by watching others
Observational learning
Stimulus that NATURALLY triggers a response
Unconditioned stimulus
UNLEARNED reaction
Unconditioned response
a previously NEUTRAL stimulus that, after association, triggers a c. conditioned response
Conditioned stimulus
LEARNED response to a conditioned stimulus
Conditioned response
US
Unconditioned stimulus
UR
Unconditioned response
CS
Conditioned stimulus
CR
Conditioned response
Gradually attain a response that is strengthened over time/exposure
Acquisition
Take away US, and CR will weaken and sipper
Extinction
Return of a CR after a brief period of nonexposure
Spontaneous recovery
Response to similar stimuli after a CR to a stimulus has occurred
Generalization
Ability to distinguish between CS and another similar but IRRELEVANT stimulus
Discrimination
The organism learns to associate a stimulus with its own voluntary behavior
Operant conditioning
B.F Skinner
Applied the science of operant conditioning to real world issues
Involves reinforcing closer and closer desired responses
Shaping
The rate of response increases
Reinforcement
The rate of response decreases
Punishment
Reward after every desired response
Continuous reinforcement
Reward after a fixed number of non-reinforced responses
Fixed-ratio
Reward after a variable number of non-reinforced responses
Variable ratio
Reward after a fixed amount of time elapses
Fixed interval
Reward after a variable amount of time elapses
Variable interval
