Q

discrimination (CC)

A

learning to distinguish betweeen CS + other stimuli that don’t signal US (e.g. generalized rsp to tone and wind chimes, dog learns to discriminate and rsp to tone only)

Q

In most cases of classical conditioning, how much time should elapse between presenting the NS and the US?

A

no more than half a second - the closer the better

Q

immediate vs delayed reinforcers

A

immediate works effectively for both humans and animals. delayed works with humans only, but only be up to 30 sec for any effect
cc - CS 0.5 sec before US…

24
Q

reinforcement schedules

A

patterns that define how often desired response reinforced. Fixed interval (every so often), fixed ratio (every so many), variable interval (every ?? time elapsed), variable ratio (every ?? many)

25
Why were Skinner's ideas controversial to some?
behaviorism rejected study of internal thought and mental processes (unobservable) which some disagreed with also manipulated subjects
26
biofeedback
system used to record and display physiological responses, using cognitive factors to influence physiological factors of stress helps mitigate tension headaches
27
response in cc
involuntary and automatic
28
response in oc
voluntary and based on environment
29
acquisition (OC)
association of a response and its consequences
30
extinction (OC)
response rate diminishing when reinforcement stops
31
spontaneous recovery (OC)
reappearance, after rest period, of an extinguished response
32
generalization (OC)
response learned in one situation occurring in (generalizing to) other similar situations
33
discrimination (OC)
learning that some responses, but not others, will be reinforced
34
John Garcia
psychologist who challenged idea that all associations learned equally well. noticed that rats that got sick from water developed ONLY taste aversion that didn't generalize to other senses. concluded classical conditioning is limited by genetic predispositions and adaptation (taste identifies poisoned food) ## Footnote biological limits on classical conditioning
35
What's an example of taste aversion?
Wolves fed sickening poison (US) in sheep (NS) carcass. Used to avert wolves from live sheep (CS) which they'd fear (CR), saving sheep and wolf lives.
36
instinctive drift
subjects of operant conditioning reverting to predisposed patterns even after conditioning shows that OC most easily retains behavior that reflects bio predispo and nat adaptation ## Footnote biological limits on operant conditioning
37
37
Robert Rescorla and Allen Wagner
psychologists who proved subjects can learn predictability of associations (expectancy limits classical conditioning). disagreed with behaviorist Pavlov b/c said NS cannot become CS w/o predictive value (which occurs via mental processes) ex: light + tone --> shock ... tone = better predictor, so stronger CR to the tone ## Footnote cognitive limits on classical conditioning
38
How do mental processes affect classical conditioning?
Organisms develop expectancy that CS signals arrival of CS
39
How do mental processes affect operant conditioning?
subjects develop expectancy that response reinforced/punished also exhibit latent learning without reinforcement
40
Edward Tolman
psychologist who discoered cognitive maps with rat maze runners
41
latent learning
learning that occurs but is not apparent until incentive to demonstrate
42
cognitive map
mental representation of layout of one's environment ex: maze running rats act as if they have mental layout of enviro, even w/o icentive contradict's Skinner's discounting of mental processes
43
insight learning
learning through sudden realization of a problem's solution no reinforcement ... thus, cog process involved
44
intrinsic vs extrinsic motivation
intrinsic: a desire to perform behavior for its own sake extrinsic: desire to perform behavior to receive promised rewards or avoid threatened punishment excessive rewards diminish intrinsic motivation (overjustification)
45
coping strategies
**problem-focused:** alleviating stress DIRECTLY - changing stressor + way we interact with it (higher success) **emotion-focused**: alleviating stress by ignoring/avoiding stressor (symptom management) * adaptive: good... ex, support from friends * maladaptive: scroll on tiktok instead of studying for test
46
learned helplessness
when unable to avoid repeated aversive events, hopelessness + passive resignation
47
Martin Seligman
discovered learned helplessness in dogs strapped to harness given repeated shocks w no opportunity to avoid ... when later given opp, didn't do so
48
internal vs external locus of control
internal: belief that we direct our own fate, correlated with achievement and health (holding self accountable) external: belief that outside factors mainly affect lives (like luck and other's treatment of you; not holding self accountable)
49
self-control
ability to delay gratification and control impulses. depleted through use.
50
observational learning
learning by studying/observing others
51
modeling
process of observing and imitating specific behavior (starts as early as 9 months old) likely to imitate those we perceive as similar, successful, or admirable
52
Albert Bandura
famous study on observ learning = Bobo Doll (violence modeling) kids saw adult act aggressively and hostile towards doll ... went on to model aggression and demonstrate NOVEL ACTS OF VIOLENCE (guns, stabbing, hammer) sidenote: lessons we learn as children not easily unlearned as adults
53
mirror neurons
frontal lobe neurons that fire when performing certain actions (or observe others doing so) may enable imitation, language learning, empathy
54
prosocial vs antisocial modeling
prosocial: positive, constructive, helpful behavior (ex: sweetness day @ payton, ppl model volunteering efforts) antisocial: violent, negative, unproductive behavior (ex: bobo doll)
55
violence viewing effect
the theory that viewing media violence leads to an increased expression of aggression
