Q

Ivan Petrovich Pavlov (1849-1936)

A

Russian physiologist

  • performing research on the physiology of digestion
  • measured dogs’ salivation to meat powder
  • however, the dogs became “psychic,” salivating when technician entered the room, or when they heard his footsteps
  • studied how stimuli (meat powder and footsteps) became associated with each other
    • isolated dog in a room
    • repeatedly rang bell and presented food
    • measured dog’s salivation to food
    • then measured salivation response to bell alone

A

repeated presentations of stimulus cause increase in response

e.g., your attention is captured by the sound of a dripping faucet

Q

habituation

A

repeated presentations of stimulus cause decrease in response. Effects a response but sensory adaptation effects the receptors sensitivity

e.g., you pay less attention to the sound of rain

Q

dishabituation

A

after presentation of a novel stimulus, habituated response reappears

e.g., the sound of thunder makes you aware of the sound of rain again

Q

stimulus generalization

A

tendency to produce a CR in response to a stimulus similar to CS

CS (yellow light) + UCS (air puff) → UCR (eye blink)

Orange light → CR (eye blink)

Q

stimulus discrimination

A

ability to distinguish and respond selectively to two different stimuli

CS+ is always followed by UCS

CS- is never followed by UCS

CS+ (yellow light) + UCS (air puff) → UCR (eye blink)

CS- (orange light) + no air puff → no eye blink

Q

Classical Conditioning Pros & Cons

A

PROS:

  • universal principles

CONS:
- mentalistic explanations may be required

25
universal principles
can be applied to animals from earthworms to people
26
Robert Rescorla & Allan Wagner (1972)
- goal: condition rats to fear a tone Group. A: tone + shock 20 times → fear response Group. B: tone + shock 20 times, mixed randomly with tone alone & shock alone 20 times → no fear response Conclusion: amount of pairing is not as important as expectation the UCS follows the CS. not all stimuli follow the “rules of learning”
27
Operant behaviours
Operant behaviours operate on the environment and produce consequences * What is the relevance of consequences of behaviour? * How can behaviours not naturally elicited be learned? * How do you get a chimpanzee to do karate?
28
B.F. Skinner (1904-1990)
- elaborated on E.L. Thorndike’s (1874-1949) Law of effect: reinforced behaviour is more likely to recur - created the operant conditioning chamber (or Skinner box): allows control of environmental contingencies - A-B-Cs  
29
A-B-Cs
specific antecedent signals that a certain behaviour will produce a particular consequence
30
discriminative stimulus
A discriminative stimulus signals that a response will be followed by a consequence - may be overt - may be covert
31
covert
an internal experience e.g., feeling hungry (→ eat → feel full)
32
overt
an objective stimulus e.g., hearing your phone ring (→ answer it → talk to your friend)
33
Reinforcement
strengthens or increases probability of behaviour it follows
34
positive reinforcement
behaviour followed by presentation of an appetitive stimulus; this increases the behaviour
35
 negative reinforcement
behaviour followed by removal of an aversive stimulus; this increases the behaviour
36
Punishment
weakens or decreases probability of behaviour it follows
37
 positive punishment
behaviour followed by presentation of an aversive stimulus; this decreases the behaviour
38
negative punishment
behaviour followed by removal of an appetitive stimulus; this decreases the behaviour
39
Reinforcement conditions
- primary reinforcer -  secondary (or conditioned) reinforcer - operant extinction - immediate or delayed
40
primary reinforcer
innately satisfying appetitive stimulus
41
 secondary (or conditioned) reinforcer
learned, via association with primary reinforcer
42
operant extinction
weakening and eventual disappearance of behaviour because it is no longer reinforced
43
immediate or delayed
humans respond to delayed reinforcement; but small, immediate ones may outweigh large, delayed ones
44
Walter Mischel & colleagues (1970; 1972): “The Marshmallow Test”
- participants: 4- and 5-year-olds at Bing Nursery School on Stanford University campus, starting in the 1960s - child placed in a room with no distractions - identified most desirable treat: marshmallows or pretzels - experimenter confirmed that child preferred two marshmallows to just one - child was given one marshmallow--and was promised a second marshmallow, if they waited until the experimenter returned in 15-20 minutes before eating the first one results: * 65% were able to wait, 35% were not * children’s self-distraction strategies.
45
delay of gratification
considered to be an index of self-control, one facet of personality
46
Mischel & colleagues (1989, 1990):
- tracked the children over time - found long-term differences between the groups - delay time positively correlated with: * higher SAT (Scholastic Aptitude Test) scores (by 210 points) * greater social and cognitive competence * better ability to cope with stress/frustration * increased educational attainment * longer-term marriages * higher incomes * greater career satisfaction * better health * lower incidence of drug use * more fulfilling lives - delay of gratification is a better predictor of a child’s grades in school than __
47
Schedules of reinforcement
- Continuous | - intermittent
48
Continuous
reinforcement given for each response PRO acquisition is rapid CON extinction is rapid
49
intermittent
only some responses are reinforced CON acquisition is slower PRO extinction takes longer
50
 fixed ratio (FR)
reinforcement given after a set number of responses
51
variable ratio (VR)
reinforcement after random number of responses (number deviates around a mean)
52
fixed interval (FI)
equal pause after each reinforcement
53
variable interval (VI)
variable length pause after each reinforcement (length deviates around a mean)
54
when is punishment most effective
(a) it follows every undesirable behaviour, and | (b) does so immediately after
55
operant generalization
responding to similar discriminative stimulus
56
operant discrimination
responding to one particular discriminative stimulus, but not another
57
shaping
reinforcing successive approximations of a desired target behaviour--typically, a complex one
58
chaining
reinforcing one behaviour then giving the opportunity to perform the next one to produce a sequence of behaviours
59
behaviour modification
1. identify and clearly define the behaviour you are targeting for change e. g., increase a desirable behaviour: exercise, defined as walking 2. self-monitor: record your behaviour baseline e. g., use a Fitbit to track your steps 3. set goal for your behaviour in measurable terms e. g., walk at least 10,000 steps every day 4. systematically apply behaviour change procedure e. g., positive reinforcement: only have dessert if you walk 10,000 steps 5. gradually reduce incentives e. g., switch from pie with ice cream, to fruit, to sugarless gum
60
Operant Conditioning Pros & Cons
PRO - behaviour is affected by consequences CONS - learning can take place without reinforcement or punishment. - reinforcement may not increase a given behaviour. - operant principles don't work equally on all behaviours
61
Instinctive drift
learned behaviours “drifted” back to species-typical behaviours - biological predispositions may be difficult to overcome  
62
Components of Social Learning Theory (Bandura, 1977)
- Attention - Retention - reproduction - Motivation
63
modeling
learning to reproduce behaviour exhibited by a model--not by direct reinforcement/punishment
64
Attention
how closely person pays attention to model’s behaviour | - factors: interest value, arousal, expectations
65
retention
how well person remembers model’s behaviour | - factors: memory strategies, cognitive level
66
Reproduction
how well person can reproduce model’s behaviour | - factors: complexity of behaviour, person’s physical skills
67
Motivation
how motivated person is to imitate model’s behaviour - factors: incentives, vicarious incentives
