Q

Operant Conditioning

A
  • B.F. Skinner (1938)
  • A learning process in which the likelihood of a specific behavior is increased or decreased through positive or negative reinforcement each time the behavior is exhibited, so that the subject comes to associate the pleasure or displeasure of the reinforcement with the behavior.

Q

Counterbalancing

A

Counterbalancing is a type of experimental design in which all possible orders of presenting the variables are included.

    • For example,
      • If you have two groups of participants:
        • group 1 and group 2
    • -Two levels of an independent variable
      • level 1 and level 2
      • You would present one possible order
        - group 1 gets level 1
        - group 2 gets level 2
      • Present the opposite order
        - group 1 gets level 2
        - group 2 gets level 1
  • This way you can measure the effects in all possible situations.

Failure of a stimulus that is part of a compound stimulus to become a CS.
- The stimulus is said to be overshadowed by the stimulus that does come a CS.

31
Q

Sensory Preconditioning

A

A procedure in which two neutral stimuli are paired, after which one is repeatedly paired with a US.
- If the other stimulus is then presented alone, it may elicit a CR even though it was never paired with the US.

32

Q

Watson’s 3 innate/instinctual fears

A
  • fear of falling

- fear of loud noises

36
Q

Conditioned Tolerance

A
  • Refers to those instances of tolerance where it is a consequence not only of neuronal adaptations to the effects of a drug, but also involves either:
    (1) associative learning in a classical (Pavlovian) conditioning situation.
    (2) differential tolerance arising from the impact of contingencies of reinforcement in operant conditioning procedures.
37
Q

Edward B. Twitmyer

A
  • Graduate student at University of Pa
  • 1902
  • Discovered classical conditioning in US before Pavlov’s work was known of.
  • Knee reflex testing
    ` paired a bell with release of hammer on knee to alert person blow was coming
    ` accidentally rang bell without hammer and person’s leg shot up
    ` did more with this and gave a speech about what it might mean but wasn’t paid attention to so he stopped his efforts and moved onto a different field.
38
Q

Positive Reinforcement

A

A reinforcement procedure in which a behavior is followed by the presentation of, or an increase in the intensity of, a stimulus.
- Sometimes called “reward training”, although the term “reward” is problematic.

39
Q

Negative Reinforcement

A

A reinforcement procedure in which a behavior is followed by the removal of, or a decrease in the intensity of, a stimulus.
- Sometimes called “escape training”

40
Q

Skinner Box

A
  • One wall has been cut away to show the inside of the box
  • The food magazine and other apparatus were contained in the space outside the left panel
  • Each time a rat pressed the level, it activated the good magazine, which dropped a few pellets of food into the tray
41
Q

Puzzle Box

A
  • Hungry cat
  • Placed food in plain sight but out of reach
  • Door that could be opened by a simple act (i.e., pulling a wire loop or stepping on a treadle)
  • Cat began by performing a number of ineffective acts and got more efficient after multiple trials
42
Q

Law of Effect

A
  • The statement that behavior is a function of its consequences
  • So called because the strength of a behavior depends on its past effects on the environment
  • Implicit in the law is the notion that operant learning is an active process because it is usually the behavior of the organism that, directly or indirectly, produces the effect.
43
Q

Primary reinforcers

A

Any reinforcer that is not dependent on another reinforcer for it reinforcing properties

44
Q

Secondary Reinforcers

A

Any reinforcer that has acquired its reinforcing properties through it association with other reinforcers
- also called “conditioned reinforcer”

45
Q

Dopamine

A

One of the brain’s major neurotransmitters and one source of a natural “high”
- It is thought to play an important role in reinforcement

46
Q

Rational Unified Process

A

The procedure of breaking down overall unified sequences into its component elements

47
Q

Motivating Operations

A

Anything that establishes conditions that improve the effectiveness of a reinforcer

  • Anything that makes a consequence more reinforcing necessarily changes the outcome of a reinforcement procedure
    - - with primary reinforcers that satisfy a physiological need, the greater the deprivation, the more effective its satisfying reinforcer will be
48
Q

Positive Punishment

A

A punishment procedure in which a behavior is followed by the presentation of, or an increase in the intensity of, a stimulus.
- Also called “type 1 punishment”

49
Q

Negative Punishment

A

A punishment procedure in which a behavior is followed by the removal of, or a decrease in the intensity of, a stimulus.
- Also called “type 2 punishment” or “penalty training”

50
Q

Extinction burst

A

A sudden increase in the rate of behavior during the early stages of extinction

51
Q

Variable Ration Schedule (VR)

A

A reinforcement schedule in which, on average, every nth performance of a behavior is reinforced

52
Q

Ration Strain

A

Disruption of the pattern of responding due to stretching the ratio of reinforcement too abruptly or too far

53
Q

Fixed Ration Schedule

A

A reinforcement schedule in which every nth performance of a behavior is reinforced

54
Q

Fixed Interval Schedule

A

A reinforcement schedule in which a behavior is reinforced the first time it occurs following a specified interval since the last reinforcement.

55
Q

Variable Ratio Schedule

A

A reinforcement schedule in which, on average every nth performance of a behavior is reinforced.

56
Q

Variable Interval Schedule

A

A reinforcement schedule in which a behavior is reinforced the first time it occurs following an interval since the last reinforcement, with the interval varying around a specified average.

57
Q

Satiation

A

A reduction in the effectiveness of a reinforcer due to exposure to or consumption of the reinforcer.
- food can be reinforcing when a person is hungry, but it loses some of its effectiveness with each bite

58
Q

Redundancy

A
  • Excessive repetition in expression.
  • Having additional, unnecessary structures.
  • Containing duplicate systems or equipment as backup to prevent failure.
59
Q

A

Any operant training procedure in which certain kinds of behavior are systematically reinforced and others are not

60
Q

Differential Reinforcement of High Rate (DHR)

A

A form of differential reinforcement in which a behavior is reinforced only if it occurs at least a specified number of times in a given period

61
Q

Differential Reinforcement of Low Rate (DLR)

A

A form of differential reinforcement in which a behavior is reinforced only if it occurs no more than a specified number of times in a given period.

62
Q

Differential Reinforcement of Zero Responding (DR0)

A

A form of differential reinforcement in which reinforcement is contingent on the complete absence of a behavior for a period of time.
- Also called differential reinforcement of other behavior because some other behavior is necessarily reinforced.

Q

Differential Reinforcement of Incompatible Behavior (DRI)

A

A form of differential reinforcement in which a behavior that is incompatible with an unwanted behavior is systematically reinforced.

64
Q

Discrimination Hypothesis

A

The proposal that the PRE occurs because it is harder to discriminate between intermittent reinforcement and extinction than between continuous reinforcement and extinction

65
Q

PRE

A

Partial Reinforcement Effect
- The tendency of a behavior to be more resistant to extinction following partial reinforcement than following continuous reinforcement

66
Q

Response Unit Hypothesis

A

The proposal that the PRE is due to differences in the definition of a behavior during intermittent and continuous reinforcement

67
Q

Frustration Hypothesis

A

The proposal that the PRE occurs because non-reinforcement is frustrating and during intermittent reinforcement frustration becomes an S+ for responding

68
Q

Sequential hypothesis

A

The proposal that the PRE occurs because the sequence of reinforced and non-reinforced behaviors during intermittent reinforcement becomes an S+ for responding during extinction

69
Q

Matching Law

A

The principle that, given the opportunity to respond on two or more reinforcement schedules, the rate of responding on each schedule will match the reinforcement available on each schedule.

70
Q
