Flashcards in Learning Deck (49):
1

Learning

A relatively permanent change in behaviour, knowledge, capability, or attitude to illness, injury or maturation

Doesn’t include
1. Short term changes
2. Physical changes

2

Classical learning

The most simplest

Association is learned between one stimulus and another

Also called classical conditioning or Pavlovian conditioning

3

Associative learning

We associate one thing with another, a positive or negative attitude
A name, gesture, style, manner

4

Reflexes

Involuntary responses to a particular stimulus

Include both conditioned and unconditioned

5

Unconditioned reflex

Inborn, automatic, unlearned response to a particular stimulus

Built into our nervous system

6

Conditioned reflexes

Learned reflexes, as opposed to naturally occurring ones

7

Unconditioned response

A response that is invariably elicited by the unconditioned stimulus without prior learning

8

Unconditioned stimulus

A stimulus that elicits a specific response without prior learning

9

Conditioned stimulus

A neutral stimulus that, after repeated pairing with an unconditioned stimulus, becomes associated with it and elicits a conditioned response

10

Conditioned response

A response that comes to be elicited by a conditioned stimulus as a result of its repeated pairing with an unconditioned stimulus

11

Extinction

The weakening and often eventual disappearance of a learned response

Weakened by repeated presentation of the conditioned stimulus without the unconditioned stimulus

12

Spontaneous recovery

The reappearance of am extinguished response when an organism is exposed to the original conditioned stimulus following a rest period

13

Generalization (Classical learning)

The tendency to make a conditioned response to a stimulus that is similar to the original conditioned stimulus

14

Discrimination

The learned ability to distinguish between similar stimuli so that the conditioned response occurs only to the original conditioned stimulus but not to similar stimuli

15

Higher order conditioning

Takes place when a neutral stimulus is paired with an existing conditioned stimulus, becomes associated with it, and gains the power to elicit the same conditioned response

16

What are the 4 factors that effect classical conditioning

1. The number of pairings of the conditioned stimulus and the unconditioned stimulus

2. The intensity of the unconditioned stimulus

3. How reliably the conditioned stimulus predicts the unconditioned stimulus(must always and only follow the stimulus)

4. The temporal relationship between the conditioned stimulus and the unconditioned stimulus (conditioned stimulus must occur shortly before the unconditioned stimulus, half a second)

17

Pavlov believes:

Believed that the critical element in classical conditioning was the repeated pairing of the conditioned stimulus and the unconditioned stimulus

18

Rescorla believes:

The importance factor is whether the conditioned stimulus provides information that enables the organism to reliably predict the occurrence of the unconditioned stimulus

19

Biological disposition

The degree to which genes prepare animals and humans to acquire or resist acquiring classically conditioned responses, are an important factor in the conditioning process

20

Seligman believes:
What is taste aversion?

Most fears are related to the survival of the human species
Humans and animals associate only certain stimuli with particular consequences

Taste aversion - the intense dislike an/or avoidance of a particular food that has been associated with nausea or discomfort

21

Drug tolerance

The user becomes progressively less affected by the drug and must take higher and higher doses tomaintain the same effects

22

Operant conditioning

A voluntary response

A type of learning in which the consequences of behaviour tend to modify that behaviour in the future

Behaviour that is reinforced will be repeated, if ignored or punished, less likely to be repeated

23

Reinforcer

Anything that strengthens a response or increases the probability that it will occur

24

Shaping

Gradually moulding a desired behaviour by reinforcing responses that become progressively closer to it, reinforcing successive approximations of the desired response

25

Skinner box

Invented by b.f. skinner for conducting experiments in operant conditioning

A sound proof chamber with a device for delivering food and either a bar for rats to press or for pidgeons to peck

26

Successive approximations

A series of gradual training steps, with each step becoming more like the final desired response

27

Generalization (operant learning)

The tendency to make the learned response to a stimulus that is similar to the one for which it was originally reinforced

28

Superstitious behaviour in operant learning

Occurs when an individual believes that a connection exists between an act and its consequences, with no relationship between the two

29

Discrimitive stimulus

The stimulus that signals whether a certain response or behaviour is likely to be rewarded, ignored, or punished

Emotions, people

30

Reinforcement

Any event that increases the probability of the response that it follows

31

Positive reinforcement

Any positive consequences that if applied after a response increases the probability of that response

Working hard for a promotion, bonus, good grades

32

Negative reinforcement

Involves learning a behaviour in order to make something unpleasant go away

Turning off, getting rid

33

Primary reinforcer

Fulfills a basic physical need for survival and does not depend on learning

Food, sleep, termination of pain

34

Secondary reinforcer

Acquired through learned by association with other reinforcers.
Can be exchanged at a later time for other reinforcers

Money, praise, grades, signals of approval, attention

35

Continuous reinforcement

Reinforcement that is administered after every desired or correct response

the most effective method of conditioning a new response

36

Partial reinforcement

A pattern of reinforcement in which some portion, rather than 100%, of the correct responses

37

Schedules of reinforcement

Systematic programs for administering reinforcement that have a predictable effect on behaviour

38

Fixed-ratio schedule

A schedule in which a reinforcer is administered after a fixed number of non reinforced correct responses

Number of units needed in order to be paid

39

Variable ratio schedule

A schedule in which a reinforcer is administered on the basis of an average ratio after a varying number of non-reinforced correct responses

Maintains behaviour against extinction

Gambling

40

Fixed interval schedule

A specific time interval must pass before a response is reinforced

Does not depend on the number of responses made, only on the one correct response made after the time interval has passed

Has a decline in responding immediately after each reinforcement, rapid acceleration in responding before the next reinforcement

Last minute studying

41

Variable interval schedule

Eliminate the pause after reinforcement, from fixed interval schedule

A reinforcer is administered on the basis of an average time after the first correct response following a varying time of non-reinforced responses

Low response rate since not directly tied to the number of responses made

42

form reinforcement, strongest to lowest

1. Fixed ratio
2. Variable-ratio
3. Fixed -interval
4.variable-interval

43

Partial reinforcement

The greater resistance to extinction that occurs when a portion, rather than 100%, of the correct responses have been removed

The lower the percentage of responses that are reinforced, the longer extinction will take when reinforcement is withheld

44

The 3 factors that influence operant conditioning

1. The magnitude of reinforcement
- magnitude of reinforcement increases, the rate of responding is higher, and resistance to extinction is higher

2. Immediacy of reinforcement
- responses are conditioned more effectively when reinforcement is immediate

3. Level of motivation of the learner
- more motivated=learn faster

45

Punishment

Lowers the probability of a response by the addition of an unpleasant stimulus or removal of a pleasant stimulus

Doesn’t extinguish undesirable behaviour, it suppressed the behaviour when the punishing agent is present

Indicates unacceptable behaviour, doesn’t help develop appropriate behaviours

Usually leads to aggression

46

What increases the effect of punishment

1. Punishment is most effective when it is applied during the misbehaviour or as soon afterwards as possible

2. Punishment should be last resort

3. Punishment should be consistent

4. Should not be administered in anger

47

Learned helplessness

A passive resignation to aversive conditions learned by repeated exposure to aversive events that are inescapable and unavoidable

48

Observational learning

“Modeling”

Learning that results when we observe the behaviour of others and the consequences of that behaviour

Stronger when several sessions of observation precedes attempts to perform the behaviour and are then repeated in the early stages of practicing it

We use it to acquire new responses or to strengthen/weaken existing ones

Useful when we find ourselves in unusual situations

Fears, agression(ban Duran doll), emotions are all observable

49

Model

The person who demonstrates a behaviour or whose behaviour is imitated

Effectiveness of a model is related to their status, competence, and power, age, sex, attractiveness, ethnicity
