Q

Shepard Siegal

A

conditioned compensatory response (CCR): a classically conditioned response in which stimuli that reliably preceded the administration of a drug that disrupts the normal level of functioning elicit a psychological reaction that counteracts the drugs effects

Q

the abc’s of operant conditioning

A

a = antecedent: discriminative stimulus (child being told no)

Q

Thorndike’s Law of Effect

A
  • responses = satisfying effect = strengthened and more likely to occur again in the same situation
  • responses = dissatisfying effect = weakened and less likely to recur in the same situation

Q

contemporary views of operant conditioning

Study These Flashcards
A
  • learned helplessness
  • exposure to inescapable and uncontrollable aversive events produces passive behavior
  • seligman and maier
25
locus of control
an individuals perceptions about the underlying main cause of events in his/her life (external vs internal locus of control)
26
observational learning
learning takes place through observing the actions of others
27
continuous reinforcement
when something comes everytime
28
partial reinforcement
more resistant to extinction, when something comes only sometimes
29
fixed ratio schedule
reinforcement after a fixed number of responses (consistant) ex: paying them treats
30
variable ratio
reinforcement after an average number of responses ex: casino slots
31
fixed internal schedule
reinforcer given for first response after present time interval has elapsed ex: payed every 2 weeks no matter how many projects they do
32
variable interval schedule
reinforcement first response after average amount of time has elapsed ex: random drug test at work
33
developmental psychology
study of how people change physically, mentally, and socially throughout their lifespan
34
genetic contributions
fertilization takes place in fallopian tube
35
zygote
single cell formed at conception
36
monozygotic twins
identical twins: when cells begin to divide (mytosis), the single zygote splits in 2, basically the same genetic material
37
dizygotic twins
fraternal twins: when two egg cells are fertilized by 2 sperm cells at approximately the same time, no more genetically similar than any other sibling
38
prenatal development
germinal stage: first two weeks embryonic stage: week 3-8 (most important physiological structures) fetal period: week 9-birth
39
teratogen
harmful agent or substance that can cause abnormal developments or birth defects
40
organogenesis
new organs
41
general principles of teratogens
- a teratogen exerts it's effects largely during critical periods - each teratogen exerts certain specific effects - either maternal or fetal genotypes may counteract a teratogens effect
42
fetal alcohol syndrome
- overall physical growth deficient - cognitive impairment - distinctive facial/physical characteristics
43
the newborn: reflexes
- involuntary physical reactions to stimuli - within hours after birth preference for mothers voice over strangers voice - brain is 25% of eventual weight of adult brain ex: sucking, rooting, and grasping reflex
44
language development
motherese = infant - direct speech - talking to infants in a slow high pitched manner with exaggerated intonation - the baby understands language faster than speaking language
45
temperament
primary pattern of reacting to the environment
46
3 basic temperament patterns
easy: positive, flexible, adaptable, regular patterns - 40% difficult: negative, withdrawing, resists change, irregular patterns - 10% slow to warm up: mildly resistant, less intense, more regular than difficult temperament 35% did not fit pattern
47
attachment
- lasting emotional tie between two people - infants form attachments with loving consistent caregivers - moat researchers focus on mother child attachment
48
John Bowlby's Ethological Theory
- infants form attachments to increase their chances of survival - attachment links nurturing adults to dependent newborns - attachment figure serves as a secure base of emotional comfort for the infant
49
Harry Harlow's Research
- contact comfort is ket cement in attachment ofrmation - contradicted the theories that maintained attachment would be formed with caregiver who provided food - cloth mother provided infants with a kind of emotional security described by Boulby
50
Mary Ainsworth's Research
- strange situation test: designed to study attachment in human infants - stranger anxiety: fear of unfamiliar adults - seperation anxiety: distress shown by infant when separated from caregiver (both considered positive)
51
secure attachment
distressed when mother leaves, greet mother happily when she returns, mother is the secure base for when exploring unfamiliar environment
52
constructivism
scheme: organized pattern of action or thought - built, modified and reorganized overtime - new experience filtered through existing schema - interaction with environment essential
53
stage one of cognitive development
-sensorimotor stage (birth - 2 years) - all experiences involve sensory input and physical actions - no mental representations of object or events
54
stage two of cognitive development
pre operational thought (2 - 6/7 years) - symbolic thought - children at this age do not think with operations (pre logical thought)
55
why do children fail pre operational tasks
1 - centration: focus on only one aspect of situation at a time 2 - static end points: focus on how things looks before and after rather than considering what happened in the transformation itself 3 - lack reversibility: do not imagine what would happen if transformation was reversed
56
egocentrism
inability to take another person's perspective
57
stage 3
concrete operation stage: 6-7/11-12
