Q

Introspection

A
  • Referred to by Wundt as “internal perception”
  • A process by which someone examines their own conscious experience as objectively as possible.
  • The process makes the human mind like any other aspect of nature that a scientist observes

Q

An example of an experiment Wundt and his students conducted in his lab

A
  • An experiment on the variable of reaction times
  • A student would receive a stimulus such as a light, image or sound.
  • The subject would be told to push a button in response to the stimulus and their reaction time would be measured to one-thousandth of a second

Q

Problems with introspection

A
  • The data is unreliable - not very valid as most psychologists accept the claim the we have very little knowledge of the causes of and processes underlying our behaviours and attitudes challenging the value of introspective reports
  • There is little agreement between individuals
  • The process is subjective - We cannot measure a person’s responses because they are unobservable responses

Q

Nisbett and Wilson (1977)

A
  • Found that participant were remarkably unaware of factors that had influenced their choice of a consumer item
  • The problem is particularly acute in the study of implicit attitudes i.e. attitudes that are unknown to us
  • A person may be implicitly racist, which influences the way they react to members of different ethnic groups, yet because such attitudes exist outside conscious awareness, self-reports through introspection would not uncover them.

Reductionism

A

An approach that reduces a complex phenomenon such as human behaviour to the simplest explanation possible. Often, this means looking for a biological basis for behaviour.

Q

B.F. Skinner (1904-1990)

A
  • An American psychologist
  • A behaviourist
  • Concentrated on how behaviour was affected by its consequences
  • Believed that behaviour is motivated by the consequences we receive for the behaviour: the reinforcements and punishments

Q

Skinner’s research device

A
  • Skinner developed a chamber that allowed the careful study of the principles of modifying behaviour through reinforcement and punishment
  • Known as an operant conditioning chamber or a Skinner box
  • Still a crucial resource for researchers studying behaviour

Q

Bandura’s ideas

A
  • Pure behaviourism could not explain why learning can take place in the absence of external reinforcement
  • He felt that internal mental states must also have a role in learning and that observational learning involves much more than imitation
  • In imitation, a person simply copies what the model does
  • In observational learning, we learn by watching others and them imitating or modeling, what they say or do
  • The individuals performing the imitated behaviour are called models
41
Q

Bandura’s 3 models

A

Live
Verbal
Symbolic

42
Q

Live model

A

Demonstrates a behaviour in person, as when Ben stood up on his surfboard so that Julian could see how he did it.

43
Q

Verbal instructional model

A

Does not perform the behaviour, but instead explains or describes the behaviour, as when a football coach tells his young players to kick the ball with the side of the foot, not with the toe.

44
Q

Symbolic model

A

Can be fictional characters or real people who demonstrate behaviours in books, movies, television shows, video games, or internet sources

45
Q

4 necessary steps for learning

A

Attention
Retention
Reproduction
Motivation

46
Q

Step 1 (attention)

A

You must be focused on what the model is doing - you have to pay attention.

47
Q

Step 2 (retention)

A

You must be able to retain, or remember, what you observed.

48
Q

Step 3 (reproduction)

A

You must be able to perform the behaviour that you observed and committed to memory.

49
Q

Step 4 (motivation)

A

You need to want to copy the behaviour, and whether you are motivated or not depends on what happened to the model.

50
Q

Vicarious reinforcement

A

If you saw that a model was reinforced for their behaviour, you will be more motivated to copy them.

51
Q

Vicarious punishment

A

If you observed the model being punished, you would be less motivated to copy them.

52
Q

Bandura’s Bobo doll experiment

A
  • A five-foot inflatable doll that he called a Bobo doll
  • Children’s aggressive behaviour was influenced by whether or not the teacher was punished for her behaviour
  • In one scenario, a teacher acted aggressively with the doll, hitting, throwing, and even punching the doll, while a child watched
53
Q

Children’s responses (Bobo doll experiment)

A
  • When the teacher was punished for her bad behaviour, the children decreased their tendency to act as she had.
  • When the teacher was praised or ignored (not punished) the children imitated what she did and even what she said, punching, kicking and yelling at the doll.
54
Q

Conclusions of Bandura’s Bobo doll study

A

We watch and learn and this learning can have both pro social and antisocial effects.

55
Q

Prosocial effects

A
  • Prosocial (positive) models can be used to encourage socially acceptable behaviour
  • Children observe and learn from heir parents, even their parents’ morals, and children tend to copy what parents do instead of what they say.
    Many public figures such as MLK are viewed as Prosocial models who are able to inspire global social change
56
Q

Antisocial effects of observational learning

A
  • May help to explain why 30% of abused children become abusive parents
  • Abused children, who often grow up witnessing their parents deal with anger and frustration through violent and aggressive acts often learn to behave in that manner themselves
57
Q

What are the principles of classical conditioning?

A

Generalisation
Discrimination
Extinction
Spontaneous recovery
Higher order conditioning

58
Q

Watson’s Behaviourist manifesto (1913)

A
  • Behaviour is a response to environmental stimulus
  • Behaviourism is only concerned with observable stimulus-response behaviours
  • This can be studied in a systematic, objective way
59
Q

Generalisation

A

Occurs when a conditioned response (CR) is elicited by a stimulus that is similar to the conditioned stimulus (CS)

60
Q

Discrimination

A

This occurs when the person or animal learns to differentiate between similar conditioned stimuli (CS) and a conditioned response no longer occurs to a similar stimulus.

61
Q

Extinction

A

When the conditioned stimulus (CS) is no longer paired with the unconditioned stimulus (UCS), eventually the conditioned response (CR) will cease.

62
Q

Spontaneous recovery

A

After extinction, it only takes a few pairings of the UCS and CS for the CR to reappear.

63
Q

Higher order conditioning

A

Also known as second order conditioning. This occurs when a previously neutral stimulus elicits a conditioned response.

64
Q

Strengths of conditioning

A
  • Scientific approach (objective)
  • Practical applications e.g. therapies
65
Q

Limitations of conditioning

A
  • Mechanistic view of human behaviour - ignore cognition and free will
  • Environmental determinism
  • Ethics of animal experiments
  • Ethics of some therapeutic approaches to changing behaviour
  • Ignores biology (nature/nurture) - there are genetic influences that could cause different people to have different responses to conditioning
66
Q

Ivan Pavlov

A
  • Russian Physiologist
  • Interested in the digestive system
  • Came to his conclusions about how learning happens by accident
  • Performed a series of very famous experiments on dogs to investigate classical conditioning
67
Q

What responses to the environment did Pavlov realise an organism has?

A

Unconditioned responses, or reflexes
Conditioned responses

68
Q

Unconditioned responses

A

Unlearned

69
Q

Conditioned responses

A

Learned

70
Q

Unconditioned responses (UCR)

A

Also known as a reflex. A natural reaction to a stimulus e.g. a dog’s salivation response when the see food.

71
Q

Unconditioned response (UCR)

A

Also known as a reflex. A natural reaction to a stimulus.
E.g. a dog’s salivation response when they see food (it is natural)

72
Q

Unconditioned stimulus (UCS)

A

A stimulus that causes a reflexive response (a UCR) in an organism.
E.g. food that causes dogs to salivate when it is presented to them

73
Q

Neutral stimulus (NS)

A

A stimulus that does not naturally elicit a response.
E.g. a tone that would ordinarily be ignored by a dog as it has no association.

74
Q

What can a neutral stimulus be paired with to cause a response?

A

An unconditioned stimulus

75
Q

Conditioned stimulus (CS)

A

A stimulus that elicits a response after it has been paired with a UCS.
A CS was once a NS but has become a CS from having an association with a stimulus that elicits a UCR.

76
Q

Conditioned response (CR)

A

A behaviour caused by the conditioned stimulus.
E.g. a salivation response when a dog hears a tone - they anticipate being fed through learning that a tone indicates that they are about to be fed.

77
Q

How did Pavlov discover classical conditioning by accident?

A

His dogs responds to the sound of laboratory assistant’s footsteps, which they wouldn’t normally react to.

78
Q

What was the UCS in Pavlov’s experiment?

A

Meat powder

79
Q

What was the dogs’ UCR in Pavolv’s experiment?

A

Salivation

80
Q

What was the NS in Pavlov’s experiment?

A

The tone

81
Q

Summary of Pavlov’s experiment

A
  • Pavlov would sound a tone (like a ringing bell) and then give the dogs the meat powder
  • When Pavlov paired the tone with the meat powder repeatedly, the previously neutral stimulus (the tone) also made the dogs salivate
  • The neutral stimulus became the conditioned stimulus
  • Eventually the dogs began to salivate to the sound of the tone alone.
82
Q

Why did behaviourism commonly use animals in experiments?

A

Due to the assumption that what was learned using animal models could partly be applied to human behaviour.

83
Q

Real world uses of behaviourism

A
  • In behavioural and cognitive-behavioural therapy
  • In classroom settings
  • In informing research on environmental influences on human behaviour
84
Q

What is behaviourism largely responsible for?

A

Establishing psychology as a scientific discipline through its objective methods and experimentation.

85
Q

Who conducted the Little Albert study?

A

Watson and Rayner (1920)

86
Q

Summary of Little Albert study

A
  • Originally, Albert showed no fear of the white rat (CS) and played quite happily with it
  • After several pairings of the loud noise (UCS) and the white rat (CS) he displayed fear (UCR) in response just to the white rat
  • Albert had learnt to fear and avoid the white rat without the loud noise present.
  • Little Albert generalised this fear to other white fluffy things including Dr Watson wearing a white beard.
87
Q

Replicable

A

The procedure can be repeated accurately

88
Q

Standardised

A

The same thing is done/said to each participant

89
Q

Controlled

A

Other variables are removed or kept constant so that they don’t affect the results

90
Q

Reductionist

A

Breaking down human experience into more easily measurable parts

91
Q

Generalisable

A

The results can be applied generally, not just to the people who took part

92
Q

Strengths of social learning theory

A
  • Supported by research - Bandura’s Bobo doll experiment
  • Has applications to the real world e.g. the role of the media and its influence on children
  • Adds to learning theory by looking at cognitive factors
93
Q

Weaknesses of social learning theory

A
  • Relies heavily on lab based research which introduces the issue of demand characteristics and suggests a lack of ecological validity
  • Ignores biological factors in behaviour e.g. boys were more likely to be violent due to higher levels of testosterone
  • Reductionist (tries to explain all behaviour from a cause-and-effect style)
94
Q

Strengths of Skinner’s research

A
  • Carried out in lab settings with highly controlled conditions, reducing the impact of extraneous variables so that findings are reliable and have scientific credibility
  • Findings have influenced reward programmes in schools and prisons. Token economies are where individuals are rewarded for showing desirable behaviours such as completing work and using manners. These have been extremely successful in modifying behaviour
95
Q

Limitations of Skinner’s research

A
  • Ignores the role of biological and genetic factors that can shape behaviours. It ignores the interaction of innate predisposition and the impact of the environment. His work could be restrictive and not give a complete explanation of human behaviour
  • Animal studies cannot be generalised to humans
96
Q

Real life example of positive reinforcement

A

A child completing chores to receive sweets. The sweets serve as a reward, reinforcing the behaviour.

97
Q

Real world example of negative reinforcement

A

When a student talking in class is given a detention, intending to decrease the likelihood of talking during class happening again

98
Q

Strengths of the behaviourist approach

A
  • Provides explanations for a range of behaviours
  • Focus on experimental methodology
  • Provides explanations for a specified behaviour e.g. phobias
  • Contributes to the nature/nurture debate
  • Approach can be applied to behavioural problems e.g. token economy
