35
Q

primary punisher

A

a stimulus that is naturally disliked by an organism.

36
Q

primary reinforcer

A

a stimulus that has survival value and is therefore intrinsically (naturally) rewarding.

37
Q

punishment

A

an experience that produces a decrease in a particular behaviour.

38
Q

reading disorder

A

a deficit in reading comprehension, written spelling, and word recognition.

39
Q

40
Q

secondary punisher

A

a stimulus that becomes strongly disliked when associated with a primary punisher.

41
Q

secondary reinforcer

A

a neutral stimulus that becomes rewarding when associated with a primary reinforcer.

42
Q

sensitization

A
  • a form of non-associative learning whereby a strong stimulus results in an exaggerated response to the subsequent presentation of weaker stimuli.
  • involves an increase, as opposed to a decrease, in response with learning
  • ex: after watching a horror movie you are startled by the floor creaking
43
Q

shaping

A

introducing new behaviour by reinforcing close approximations of the desired behaviour.

44
Q

spatial navigation learning

A

learning that involves forming associations among stimuli relevant to navigating in space.

45
Q

specific learning disorder

A

a disorder that interferes with the acquisition and use of one or more of the basic psychological processes involved in the development of academic skills: oral language, reading, written language, and mathematics.

46
Q

spontaneous recovery

A

re-emergence of a conditioned response sometime after extinction has occurred.

47
Q

stimulus discrimination

A

what occurs when an organism learns to emit a specific behaviour in the presence of a conditioned stimulus, but not in the presence of stimuli similar to the conditioned stimulus.

48
Q

stimulus generalization

A

what occurs when stimuli similar to the original conditioned stimulus trigger the same conditioned response.

49
Q

systematic desensitization

A

a process used to condition extinction of phobias through gradual exposure to the feared object or situation.

50
Q

unconditioned response (UR)

A

a physical response elicited by an unconditioned stimulus; it does not need to be learned.

51
Q

unconditioned stimulus (US)

A

a stimulus that on its own elicits a response.

52
Q

variable interval schedule

A

a schedule of reinforcement that occurs after varying amounts of time.

53
Q

variable ratio schedule

A

a schedule of reinforcement that occurs when the number of responses required for reinforcement is unpredictable.

54
Q

vicarious learning

A

learning that occurs when an individual observes the consequences to another’s actions and then chooses to duplicate the behaviour or refrain from doing so.

55
Q

3 definitions of learning

A
  1. Mechanisms of behaviour
  2. enduring changes
  3. results from prior behaviour
56
Q

Mechanisms of behaviour

A

• Learning Is an abstract concept
• Behaviour change is not part of definition
○ Behaviour change refers to performance
○ Learning may occur without change in performance
○ Performance may change due to factors other than learning
• Learning is inferred by change in performance

57
Q

Enduring change

A

• Behaviour change induced by learning must be “enduring”
• There are some pronounced behavioural changes that are not enduring, and are therefore not learning:
i. Fatigue
ii. Change in stimulus conditions
iii. Alteration in physiological/motivational state

58
Q

Results from prior experience

A
  • Behavioural change induced by learning must result from prior experience with those or similar stimuli
  • Even enduring changes in behaviour that do not result from experience with environmental events aren’t classified as learning (e.g., Maturation).
59
Q

2 examples of non-associative learning

A
  1. Habituation

2. Sensitization

60
Q

Pavlov did what, and what type of learning did it fall under?

A

Pavlov: recorded salivation, precisely measure it to see how much salivation and when it increased

  • develop behaviour and drive meaning
  • Associative learning
61
Q

2 examples of associative learning

A
  • pavlov (classical conditioning)

- lil albert (operant conditioning)

62
Q

schedules of reinforcement

A

a program or rule that specifies how and when a response will be followed by a reinforcer

63
Q

“simple” schedules

A
  • Single factor (e.g, time, number of responses) determines which response will be reinforced
  • Continuous reinforcement (CRF)
  • Partial or intermittent reinforcement
64
Q

classification of simple schedules

A
  • Response-based only; Ratio schedules
  • Time and response-based: Interval schedules
  • Requirement: Fixed or Varying
65
Q

concurrent schedules

A

Schedules that consist of a combination of two or more simple schedules

66
Q

Matching law

A

is a quantitative relationship that holds between the relative rates of response and the relative rates of reinforcement in concurrent schedules of reinforcement.

67
Q

4 factors affecting learning

A
  1. Timing- massed vs spaced
  2. Sleep
  3. Attention- divided attention and multitasking
  4. Context- performance improved if context is the same at as at study
68
Q

Prenatal and postnatal memory

A
  • facial imitation at birth

- classical conditioning before birth

69
Q

Learning disorders

A

○ Persist 6 + months
○ No/little improvement from intervention
○ Cannot be explained by:
§ Sensory problems
§ Intellectual impairment
§ Emotional disturbance
§ Environmental, cultural, or economic disadvantage

70
Q

Qualitative change

A

it is not just that we are bigger, faster, or more coordinated, but that we are different in some way.

71
Q

Quantitative change

A

involves gradual increases in some element, such as height or weight

72
Q

Nature vs Nurture

A

How much of our growth, personality, and development is attributed to our genetic inheritance or the environment we grow up in is still a key debate in human development.

73
Q

Factors affecting learning

A
  • environment
  • mental emotional
  • technology
  • social
  • culture
74
Q

who was Ivan Petrovich Pavlov?

A
  • discovered Classical conditioning
  • discovery of conditioned reflexes made it possible to study psychic activity objectively and led the way to a systematic investigation of associative learning in the laboratory
  • interested in understanding the role of the salivary reflex on the action of the stomach during digestion
75
Q

The research of Shepard Siegel at McMaster University on Drug dependency & its relation to classical conditioning

A

Drug dependency involves the psychological and physiological experiences that occur as the individual continues to use the drug; the body adapts to the presence of the drug and the individual experiences withdrawal if the drug is reduced or stopped.

76
Q

How is the nervous system undergoing classical conditioning with addicts? what’s the consequence of this?

A

the nervous system, due to classical conditioning, anticipates the arrival of the heroin based simply on external environmental cues (called extroceptive cues) provided by the location (e.g., the room, drug paraphernalia, or other characteristic sights and sounds) in which the addict shoots up
-without these counterbalancing effects, the addict’s system may become overwhelmed by the usual dose of heroin, suppressing respiration and killing the individual

77
Q

Fear conditioning was first studied by whom? what’s and example?

A

Watson, “lil albert”

78
Q

“Little Albert.”

A

Albert had no fear of the rat, but as he reached forward to touch it, Watson used a hammer to strike a steel bar just behind Albert’s head. This loud sound frightened Albert so much that he burst into tears (see photo). Seven pairings of the white rat (CS) with the loud noise (US) made Albert cry and avoid the rat (CR).
-ex of stimulus generalization (feared any fuzzy animal)

79
Q

why was little albert unethical?

A
  • his mother was never informed of Albert’s participation in the study
  • study was carried out without regard for the suffering caused to Albert or for the possibility that there would be lasting harmful effects on Albert’s emotional state
80
Q

Neuroimaging studies suggest that phobias involve abnormal activity in what part of the brain?

A

amygdala, a part of the brain that is active when we experience emotions, including fear

81
Q

operant conditioning, psychologist Edward Thorndike did what?

A
  • created a contraption called a “puzzle box.” This was a cage into which Thorndike placed a hungry cat.
  • He called this type of learning instrumental conditioning because the response (stepping on the pedal) was essential (instrumental) to receiving the reward (escape and food).
  • Skinner believed that organisms didn’t simply respond to the environment; instead they exerted influence (or “operated”) on the environment, so he called this form of learning operant conditioning.
