Q

what is classical conditioning?

A

a form of associative learning

  • neutral stimulus becomes associated with a stimulus which the learner has an inborn, automatic reponse to.
  • pavlov’s dogs

Q

Pavlov’s Dogs experiment

A

began with just researching on saliva and digestion in dogs

  • discovered classic conditioning accidentley
  • put tube in dogs mouth to collect salvia then put meat powder in dog’s mouth
  • after a while noticed the dogs began to salivate when he took out the tube

Q

the two most fundamental criteria for stimulus-response conditioning?

A

1) multiple pairings of the neutral stimulus (conditioned stimulus) and the unconditioned stimulus need to happen for association to occur and for the conditioned stimulus to illciet a response
2) the unconditioned stimulus and the conditioned stimulus must be paired together very close in time in order for an association to form

Q

punishment

A

a stimulus that results in the decreased frequency of the behaviour

32
Q

postive punished

A

the addition of a stimulus that results in decreased behaviour
- spanking a child to stop bad behaviour

33
Q

negative punishment

A

decreased behaviour as a result of the removal of a stimulus

- taking away phone to decrease a childs bad behaviour

34
Q

what did BF Skinner think was more successful, reinforcement or punishment?

A

reinforcement

35
Q

What is the Skinner Box?

A

box where animal can move around
inside there is a trigger they can push where eventually they get food
- might be several pushes, depending on experiment

36
Q

Thorndike’s puzzle box?

A

box where animals needed to hit lever to get door to open to escape
only had to push lever once
resulted in faster getting out time by animals after several trials

37
Q

what did the skinner box test?

A

effort animal is willing to exirt in order to get paticular result they want
- direct measure of motivation

38
Q

elements of the modern skinner box?

A
  • lever to press to deliver food as reinforcer
  • small region of floor can be set up to deliver shock as punishment
  • enough room for animal to move around
39
Q

how do the rats figure out what the lever for food means in the first place?

A

by using process called shaping

reinforcing successful approximations of a desired behaviour

40
Q

extinction in operant conditioning?

A

extinction occurs when behaviour stops being reinforced

ex: rat stops getting food after pushing lever multiple times

41
Q

continuous reinforcement

A

reinforcing a behaviour every time it happens

ex: reward dog every time he sits

42
Q

intermittent/ partial reinforcement

A

not getting reinforced after every response

ex: call someone, they answer most times, not always

43
Q

which produces stronger behavioural responses? intermittent or continuous reinforcement?

A

intermittent

  • no predictable pattern of reinforcement
    ex: animal gets food sometimes after hitting lever, it will hit lever very often in hopes of getting more food
44
Q

category of four types of intermittent reinforcing called what

A

schedules of reinforcement

1) fixed ratio schedule
2) variable ratio schedule
3) fixed interval schedule
4) variable interval schedule

45
Q

fixed ratio schedule

A

reinforcement follows set number of responses

ex: hit lever 5 times to get supper
- fast then slow; scalloped pace as individuals know pattern

46
Q

variable ratio schedule

A

the number of responses needed for reinforcement varies

- produces steady pace of responses as individual does not know pattern

47
Q

fixed interval schedule

A

individuals get reinforcement after set amount of time after first response

  • does not matter how many responses after first, will not change time intervals
    ex: studying for exams, no matter how many times you open book to study, exam happens at same day and time
48
Q

variable interval schedule

A

reinforcement happens after variable amounts of time after first response
- usually follow for a general mean

49
Q

did skinner believe that he could teach an animal anything?

A

yes with positive reinforcement

50
Q

biological limitations/ constraints on conditioning experiment

A

skinner students did experinment

  • eventually ventured to species who had not been tested
    - pigs, raccoons, chickens ect
  • training to insert poker chips in machine
  • pigs rooted them
  • chickens peck
  • raccoons ‘washed’ hands with them
  • these behaviours became worse as time went on
51
Q

instinctive drift?

A

learned behaviour that shifts towards natural, instinctive, unlearned behaviour

52
Q

biological constraint model of learning

A

model that says some behaviours are inherently more likely to be learned than others

53
Q

why are biological contraints a thing?

A

they have helped us survive, our bodies know what works for survival and what doesn’t, it has taken millions of years to get to where we are no by learning what we have learned

54
Q

imprinting

A

the rapid and inborn learning of the characteristics of a caregiver within a very short period after birth

55
Q

ethology

A

the scientific study of animal behaviour

56
Q

explain imprinting in real life

A

baby birds learn to follow whoever they imprinted on, whoever they saw the most, they would learn to follow them and learn from them

57
Q

sensitivity period?

A

the period of time that an animal that imprints learns the most
- a period when a particular type of learning occurs easily id the animal is exposed to particular stimulus or situation

58
Q

can imprinting happen in another time in the lives?

A

learning learned during the imprinting is pernament, and imprinting cannot be relearned, unlearned or alterned in anyway

59
Q

what is latent learning?

A

learning that occurs in the absence or reinforcement and is not demonstrated until later when reinforcement occurs
rats in the maze
group one rewarded with food
group two receieved no food
group three receieved no food at first, then did

60
Q

enative learning

A

learning by doing

- in the act

61
Q

observational learning

A

learning by watching

62
Q

Albert Bandura’s social learning theory

A

theory of the kinds of learning that occurs when we model or imitate the behaviours of others

63
Q

modelling in social learning?

A

observing and imitating beaviours performed by others

ex: younger childern imitating older siblings

64
Q

social learning and reinforcement?

A

social learning also works with reinforcement

  • watch the reinforcement that happens to others when they perform a behaviour, learn from their mistakes or good acts
    ex: childern and adults hit or play nice with the inflatable doll
65
Q

Banduras inflatable doll experiment

A

the childern imitated the either good behaviour, playing nice, with the doll or the aggressive, punching the doll, behaviour they saw the adult perform with the doll
- repeated experiment, showed kids te aggresive man was punished for his behaviuor , or rewarded, based on whatever video that group was shown

  • if they saw punishment video, their behaviuor was much less aggressive,
  • if they saw the rewarded video, the childern were very aggressive with doll and eachother
66
Q

Watson’s and Skinner’s perspective on learning

A

all learning was a function or wither stimuli (classical conditioning), or consequences (operant conditioning) which both came from the outside environment

67
Q

what about genetics and behaviour?

A

Watson ignored the role of genetics, as it could not be observed
skinner acknowledged the role of genetics in behaviour

68
Q

fear conditioning

A

little albert

69
Q

common method of fear conditioning measurement?

A

freezing

animal stops all movement in repose to conditioned stimulus

70
Q

what affected freezing behaviour in animals?

A

the amygdala

the freezing behaviour happen very little with animals whose amygdala was damaged

71
Q

what else is the amygdala important in in learning?

A

associative learning to positive unconditioned stimulus such as tasty foods

72
Q

nucleus accumbens and leanring

A

reward

brain becomes activated here whenr ewarded with money

73
Q

what neurotransmitter si involved with nucleus accumbens and can effect the rats behaviuor based on its abundance?

A

dopamine plays important role

- blocking dopamine reduces rats effort in order to receive food

74
Q

how long until human babies begin using imitation to learn?

A

7 hour old babies will begin imitates simple adult facial expressions

75
Q

imitation experiment with monkeys?

A
  • accidental discovery
  • same neurons fired when monkey saw experiment grab an object as when the monkey, itself grabbed an object
  • conclusion: mirror neurons support the function of rehearsal during learning. By watching others actions, we “exercise” the areas of our brain that are involved in make those actions if we did them ourselves. Helps us perofrm behaviuors when its our turn to do so
76
Q

important: learning in essence is

A

the growth of new synapse

77
Q

learning— enriched environments help or not?

A
  • enriched or neutral environments helped rats grow more neural connections then genetically identical rates who were raised in impoverished environments
  • animals do not have to be in enriched environments since birth to benefit from them
  • longer life in enriches environments the more neural growth in hippocampus
