Q

Describe how a graph, showing the acquisition of a condition response, would look like

A
  • There is a learning curve which forms an Ogive

1) There is a slow but gradual increase in response strength in the first few initial trials
2) A few trials later (middle of the graph), there is a rapid increase in response
3) In the later trials, the rate of response slows down but still increases, as a result of practice/training (negative acceleration)

Q

What type of conditioning is this?

1) You salivate when there is meat
2) Meat is paired with the ringing of a bell repeatedly
3) You salivate when both meat and bell are present
4) You even salivate when the bell is present but not the meat
5) When the bell is paired with the smell of oranges you also salivate
6) When you smell the scent of oranges even without the ringing of the bell or the presence of meat, you still salivate

26
Q

What is this an example of?

1) Wolf salivates to the “Cat Shack” signboard and has officially been conditioned to respond this way once it recognises the signboard
2) However, Wolf also salivates when it sees the “Crab Shack” signboard as well as the “Tool shack” signboard because they share similarities with the “Cat Shack” sign
3) But once Wolf goes into the other shacks, it no longer salivates as there are no cats present

Q

What is Discrimination?

A

The ability to differentiate between a conditioned stimulus and other similar stimuli that have not been paired with an unconditioned stimulus

28
Q

What is this an example of?

1) In early trials, Wolf generalises to “Tool Shack” and “Crab Shack” signboards
2) Later, Wolf learns that the “Tool Shack” and “Crab Shack” do not have cats present and stops salivating to them
3) Thus, Wolf no longer salivates to other signboards other than the “Cat Shack” signboard
4) Wolf learns that tool shack with no cats/food is an inhibitor

A

Discrimination

29
Q

What is the difference between classical and operant conditioning?

A
  • Classical involves presenting CS with US to train a CR for an involuntary behaviour with stimulus
  • Operant involves presenting reinforcements (rewards) and punishments which train voluntary behaviour with consequences
30
Q

What is Conditioned Fear?

A

A state of fear/anxiety after a few pairings of a threatening stimulus with a formally neutral stimulus using classical conditioning

31
Q

What is this an example of?

1) Wolf fears getting electrocuted and stops salivating when it sees the electrocution machine
2) Wolf repeatedly hears footsteps before it gets electrocuted
3) After a few trials, when the Wolf hears the sound of footsteps, it stops salivating and expects to be electrocuted
4) Wolf suppresses salivation when it hears footsteps and feels fear instead

A

Conditioned Fear

32
Q

Who performed and introduced the Conditioned Emotional Response Procedure?

A
  • Estes and Skinner
  • Kamin
33
Q

What is this an example of? (Type of response to a stimulus)

A

Unconditioned response to the taser

34
Q

What is this an example of? (Type of response to a stimulus)

When exposed to the sound of footsteps, after being conditioned to expect being tasered afterwards, Wolf freezes and goes tense in anticipation

A

Conditioned response to the footsteps, following the taser

35
Q

How does Classical Conditioning apply to Diabetes and drug use?

A
  • Diabetic patients inject insulin to lower their blood sugar levels
  • After many injections, the sight of the needle starts to trigger an early physiological response (increase in blood sugar levels)
  • Body strives for homeostasis and conditioned response prepares for the unconditioned stimulus (compensatory reaction)

A
  • BF Skinner
  • Edward L. Thorndike
38
Q

What does Operant Conditioning explain?

A

A learning process in which the behaviour is repeated either through reinforcement or punishment

39
Q

If a dog salivates, they are rewarded with meat. What type of conditioning is this?

A

Operant conditioning

40
Q

Who believed that actions are not just reflexes, but are voluntary?

A

BF Skinner

41
Q

What term is used when:

1) A behaviour that is followed by a pleasant consequence is likely to be repeated
2) A behaviour that is followed by an unpleasant consequence is less likely to be repeated

A

Law of effect

42
Q

What does the Law of effect explain?

A

1) A behaviour that is followed by a pleasant consequence (reward) is likely to be repeated
2) A behaviour that is followed by an unpleasant consequence (punishment) is less likely to be repeated

43
Q

Which experimenter tested operant conditioning with rats?

A

BF Skinner

44
Q

What is this an example of?

1) Rats are put in a box
2) Box has a lever that drops food if pressed
3) Rat learns that if it presses the lever, food will drop and continues to repeat this response

A

Operant conditioning with positive reinforcement

45
Q

What are the conditioned response and reinforcement/punishment in this example?

1) Rats are put in a box
2) Box has a lever that drops food if pressed
3) Rat learns that if it presses the lever, food will drop and continues to repeat this response

A

CR = Pressing the lever
Reinforcement = Food

46
Q

What did Edward Tolman contribute to the research of conditioning?

A

Tolman’s Maze

47
Q

What happened in Tolman’s Maze?

A
  • Rats were left in the maze for a week
  • They were given rewards (food)
  • Findings show that rats learned to navigate around the maze quicker when given rewards than when they were not given rewards
48
Q

What is Contiguity?

A

For learning to occur, the US must occur very soon after the CS is presented, or else an association will not occur

49
Q

What term is used to describe that for learning to occur, the US must occur very soon after the CS is presented, or else an association will not occur

A

Contiguity

50
Q

What is Contingency?

A
  • Stimulus must reliably occur before the event
  • Stimulus must have a link/relationship with the event
51
Q

What term is used to describe when stimulus must RELIABLY occur before the event and must have a link/relationship with the event

A

Contingency

52
Q

Which theory argues that other types of learning are not explained by operant and classical conditioning?

A

Contingency effects theory

53
Q

Which theory argues that in order for learning to occur, a stimulus must provide the subject with information about the likelihood that a certain event will occur?

A

Contingency effects theory

54
Q

What does the Contingency effects theory explain?

A

In order for learning to occur a stimulus must provide the subject with information about the likelihood that an event will occur

55
Q

What did Rescola investigate about contingency effects?

A

Rescorla
1) Rats are exposed to tone (CS) and shock (US)
2) Tone is not always presented before the shock
3) In 2 groups of rats, tone indicated 40% chance of shock
4) Group 1 = Rats were given extra shocks without warning, tones were less used and rats learned to ignore the tone
5) Ground 2 = Rats had a much lower chance of shock and were not given a tone
6) Findings = Tone was somewhat useful as rats showed conditioning

56
Q

How do animals learn?

A
  • By surprise
  • If the result is unexpected, the animal changes their sensitivity to a situation
57
Q

Who introduced the blocking effect?

A

Leon Kamin

58
Q

What is the blocking effect?

A
  • When the conditioning to a stimulus is blocked
  • Happens when a stimulus (associated with target behaviour) is presented with a 2nd stimulus that was previously a reliable predictor (contingent) of that outcome
  • AKA if CS2 is presented at the same time as CS1 (a CS already associated with US), it is more difficult to associate between CS2 and US
59
Q

Who introduced Latent Learning?

A

Tolman and Honzik

60
Q

What is Latent Learning?

A
  • The acquisition of new knowledge without change in behaviour
  • Knowledge that is not that obvious at the time of learning but manifests later when there is a suitable motivation
61
Q

Which researchers tested Latent Learning in desert ants?

A

Harkness and Marouda

62
Q

What did Harkness and Marouda discover about Latent Learning in desert ants?

A

1) Desert ants leave nests to look for food
2) After finding food, the ants head straight back to the nest
3) Food can be as far as 50m away from the nest
6) Ant uses movement velocity to update their position to carry the food
7) Findings indicate learning without conditioning
8) The ants had subconsciously retained info without motivation or reinforcement

63
Q

Who introduced Cognitive Map theory?

A

Tolman

64
Q

What does the Cognitive Map theory suggest?

A
  • Memories of RECENTLY travelled routes are combined with memories of PREVIOUSLY travelled routes to create an integrated map of the environment
  • The reason why individuals can successfully navigate via spatial positioning is that they can use a map in their memory as a representation of space during navigation
65
Q

What explains non-result based learning?

A

Cognitive Map theory

66
Q

What type of conditioning uses the law of effect?

A

Operant conditioning

67
