Q

What is neobehaviorism?

A

Believes that the core of psychology is the study of learning. Most behavior, no matter how complex, can be accounted for by the laws of conditioning. Psychology must adopt the principle of operationism

Q

What is operationism?

A

The idea that the validity of any scientific finding is based on the validity of the methods used to arrive at that conclusion. Physical concepts must be defined precisely. Concepts that cannot be operationalized should be discarded.

Q

What was Tolman’s counter argument to the Watsonian behaviorists?

A

Measurements taken are stated in terms of changes in overt responses as a function of learning or experience. So long as measurements yield objective data, it is still in the spirit of behaviorism.

Q

What are intervening variables?

A

A set of unobservable and inferred factors within an organism that connects the stimulus and response (ex: cognitions, expectancies, purposes, appetites). Need to be operationalized (ex: hunger measured by length of time between meals)

33
Q

What are drives?

A

A state of need due to a deviation from optimal bodily conditions- arouses or activates behavior.

34
Q

What is the basis for reinforcement according to Hull?

A

Reduction of the drive.

35
Q

What is the strength of drive determined by?

A

Length of deprivation and intensity of the response behavior.

36
Q

What are primary drives?

A

Innate biological needs that are vital to survival (ex. food, water, air, sex)

37
Q

What are secondary drives?

A

Stimuli associated with the indirect reduction of primary drives (ex. desire for wealth, fear of pain-inducing stimuli)

38
Q

What is Hull’s law of primary reinforcement?

A

Learning cannot take place in the absence of reinforcement, and the reinforcement must satisfy a drive. If a stimulus-response connection produces a reduction in primary drives, then the likelihood of the same stimulus evoking the same response increases.

39
Q

What is habit strength?

A

The strength of the stimulus-response connection

40
Q

What were Hull’s contributions to psychology?

A

Many citations
Defended and expanded influence of behaviorism in the US
Trained many students including Hilgard and Mowrer
Hull’s behaviorism won over Tolman’s but lost to Skinner’s.

41
Q

Who was B. F. Skinner?

A

Came from a warm home with strict moral standards. Degree in English from Hamilton College. Wanted to become a writer but didn’t find success, considered himself a failure. Read Watson and Pavlov’s conditioning experiments which awakened a scientific interest- psychology at Harvard.

42
Q

Who has the most citations to date?

A

B. F. Skinner (the most influential psychologist of all time)

43
Q

What was Skinner’s empty organism approach?

A

A descriptive form of behaviorism. Focused efforts on describing behavior rather than explaining it. Wasn’t interested in intervening variables or drives. Believed human beings are controlled and operated by environmental forces.

44
Q

What did Skinner believe about sample sizes?

A

Wasn’t necessary to use large ones- conducted comprehensive investigations on a single subject.

45
Q

What is classical conditioning?

A

A behavior elicited by a specific observable stimulus

46
Q

What did Skinner call classical conditioning?

A

Respondent behavior

47
Q

What is operant conditioning?

A

A behavior that occurs spontaneously without an observable stimulus (operant behavior).(ex: Rat pressing lever and getting food)

48
Q

What is the law of acquisition (Skinner)

A

The strength of an operant behavior increases when it is followed by the presentation of a reinforcing stimulus. Practice can lead to more efficient behavior, but reinforcement is required to increase rate of responding

49
Q

How does operant conditioning differ from Thorndike and Hull’s positions?

A

Purely descriptive- only explains that the rat is behaving a certain way in these conditions, but does not try to explain why.

50
Q

What are schedules of reinforcement (Skinner)

A

Developed because Skinner was running low on food pellets and decided to ration and reinforce the rats once per minute (regardless of responses). Found that frequency affects extinction.

51
Q

What are the 4 interval schedules of reinforcement?

A
  1. Fixed ratio schedules
  2. Variable ratio schedules
  3. Fixed interval schedules
  4. Variable interval schedules
52
Q

What are fixed ratio schedules?

A

Food is dispensed after the rat presses the lever X number of times. Result: high and steady response rate, brief pause after dispensation.

53
Q

What are variable ratio schedules?

A

Food is dispensed after the rat presses the level 5 times, then after 10 times, 7 times etc. Result: High and steady response rate

54
Q

What is the fixed interval schedule?

A

Food is dispensed after a fixed length of time has passed since the rat first pressed the lever. Result: high rate of response nearing dispensation, slowed rate of response after.

55
Q

What is the variable interval schedule?

A

Food is dispensed after an unpredictable length of time has passed since the first lever press. Result: Slow and steady response rate.

56
Q

What is successive approximation (shaping)?

A

Reinforcement changes in successive stages as the human or animal approaches the final desired behaviour.

57
Q

What is the idea of shaping of language?

A

Infants spontaneously babble, which are reinforced by parents smiling, laughing, and talking. Stronger reinforcers are provided by parents when babbling becomes more like words. As words become more common, parental reinforcement becomes restricted, given only for correct words and pronunciation.

58
Q

What was Chomsky’s language acquisition device?

A

Humans are born with a language ability that develops

59
Q

How do we modify behavior according to Skinner?

A

Using reinforcment. Socially desirable behaviors should be reinforced with smiles, praise, and affection. Undesirable behavior should not be punished.

60
Q

What is the idea of token economies?

A

Hospitals, schools, psychiatric facilities. Behavior is reinforced through tokens, tokens exchanged for items.

61
Q

What is Applied behavior analysis?

A

Primarily used for individuals with autism spectrum disorder. One-on-one intervention using positive reinforcers.

62
Q

What are some criticisms of Skinner?

A

Extreme positivism and opposition to theory
Instinctive drift showed that reinforcement not as all powerful as Skinner claimed
Stronger evidence for Chomsky’s view of language acquisition.
Radical behaviorism with little room for cognition

63
Q

What were Skinner’s contributions?

A

World’s most famous psychologist for decades
Beyond Freedom and Dignity
Promoted behavior modification and its clinical application in hospitals, factories, schools.
Involved in the invention of an automated crib for tending infants and teaching machines
Methods still in use today.

64
Q

Who was Albert Bandura?

A

Discovered psych by accident and UBC. Regarded as one of the most influential psychologists of all time. From small town Alberta.

65
Q

What is social cognitive theory (Bandura)

A

Less extreme form of behaviorism which incorporates cognitive aspects. Believed humans were not like machines and that internal motivators influence behavior. Importance of rewards or reinforcement in acquiring and modifying behavior

66
Q

How can learning be done according to Bandura?

A

Through modelling and observation of others and through vicarious reinforcement- observing the behavior of others and it’s consequences (direct experience not necessary to learn)

67
Q

Who are people more likely to model their behavior after?

A

A person of the same sex, age, their peers, or those who have solved similar problems to their own.

68
Q

What types of behaviors are more easily imitated?

A

Simple over complex

69
Q

How effective is modelling?

A

It can vary- hostile and aggressive behaviors also tend to be strongly imitated

70
Q

How was Bandura’s approach in opposition to Skinners?

A

Criticized the use of individual, isolated subjects. No direct link between behaviour and reinforcement- link is mediated by cognitive processes

71
Q

What did Bandura believe about the schedule of reinforcement?

A

The schedule itself does not change the behavior, rather it is what the person thinks the schedule of reinforcement is.

72
Q

What is self-efficacy?

A

One’s sense of self-esteem and confidence in dealing with life’s problems- people vary in their responses to events based on this.

73
Q

What were Bandura’s contributions?

A

Principles of social cognitive theory and modelling applied to behavioral therapy. Snake example

74
Q

What is the snake example?

A

A subject who is afraid of snakes watches a model play with one from a distance. Subject is prompted to move closer, and progressively learns that the snake is harmless. Movements towards snake are reinforced through praise and encouragement, increasing self-efficacy. Eventually subject gets close enough to the snake that they can touch it and play with it.

75
Q

Who was Julian Rotter?

A

Read both Freud and Adler in his youth, financial hardship during Great Depression influenced his views on social injustice.

76
Q

What did Rotter believe about cognitive processes?

A

Promoted the inclusion of cognitive experiences in behaviorism. Emphasized that internal cognitive states, such as subjective expectations and values influence the effect of external experiences. This varies between people.

77
Q

How did Rotter believe that we learn?

A

Primarily through social experiences, critizied the isolation of subjects.

78
Q

What did Rotter believe the link between behavior and reinforcement is mediated by?

A

Cognitive processes

79
Q

What is the locus of control?

A

Something that causes people to vary in their responses to events.

80
Q

What is the internal locus of control?

A

Belief that reinforcement depends on one’s own behavior.

81
Q

What is the external locus of control?

A

The belief that reinforcement depends on outside forces.

82
Q

Which locus of control is considered to be physically and mentally healthier?

A

Internal
