Q

Who established the behaviourist approach, who else contributed what was the overall assumption of the approach?

A

John B Watson established the approach in 1913 it also includes work from Ivan Pavlov (1927) and skinner (1938) - it rejected the vagueness of introspection and focuses instead on observable events and how behaviour is shaped by the environment

Q

Explain the main assumption of the behaviourist approach?

A

Environmental stimuli shape behaviour - for example a stimuli in the environment (eg a spider) will cause us to respond in a certain way (eg being scared)

Q

Explain 3 other assumptions of the behaviourist approach?

A
  • blank slate - when we are born our mind is like a ‘tabula rasa’ - what we learn through our interactions with the environment determines our behaviour
  • behaviour is learnt though conditioning - both classical and operant
  • humans and animals learn in a similar way - therefore findings on animals can be applied to predict and generalise human behaviour

Q

What is the behaviourist approaches stance on ‘nature v nurture’ debate?

A

Behaviourist falls on the ‘nurture’ side as behaviour is determined by factors external to the individual (overruling any innate or biological factors such as genes, hormones or evolution)

Q

What is the behaviourist approaches stance on determinism v free will?

A

Behaviourist approach is firmly on the deterministic side, as we are born as a blank slate shaped by the environment - as children we have little to no control over the environment

  • approach does acknowledge small contribution of free will - we are able to shape and choose our environments at times

Q

What is a problem with the behaviourist approach siding with determinism?

A

Undermines the sense of choice or free will that humans have when making designs - validates the idea we have no personal or moral responsibility for our behaviour leads to a ‘blame culture’ (for example someone may display aggressive behaviour and blame the environment rather than it as something they are responsible for)

Q

What is a strength with the behaviourist approach siding with determinism?

A

Recognising the role of determinism in behaviour means we know what factors have pre-determined a behaviour such as a persons phobia - which means we can aim to alter these factors in an attempt to change the behaviour

Q

What is a strength of the behaviourist approach being scientific?

A

Approaches that use scientific methods to investigate ideas tend to be seen as more credible due to higher quality of supporting evidence - also important as psychology as a subject aims to be scientifically recognised

Q

Explain what classical conditioning is?

A

Classical conditioning is learning through association, it was discovered by Pavlov and involves two stimuli being linked together to produce a new learned response in a person or animal

Q

Explain the work of Ivan Pavlov in 1927?

A

Investigated the salivary reflex in dogs and noticed that animals not only salivated when food was in their mouths but also when their was the presence of a food bowl or the person that fed them - led him to experiment and showed that dogs could be conditioned to salivate to a conditioned stimulus (sound of a metronome)

Q

Explain 3 things Pavlov showed or disscovered?

A
  • dogs could be conditioned to salivate to the sound of a metronome (a conditioned stimulus)
  • discovered that unlike the UCR the CR does not become a permanently established response - it can be unlearnt
  • stimulus generalisation - once the animal has been conditioned it responds to a stimuli similar to the CS

Q

Explain the neutral stimulus (NS) in Pavlov’s experiment with salivating dogs?

A

before conditioning takes place the neutral stimulus has no effect on behaviour - sound of the metronome was the neutral stimulus (did not cause the dogs to salivate)

  • becomes the conditioned stimulus

Q

Explain the unconditioned stimulus (UCS) in Pavlov’s experiment with salivating dogs?

A

stimulus that naturally and automatically triggers a response without any learning needed - the food was the unconditioned stimulus as it automatically induced salivation in the dogs

Q

Explain the conditioned stimulus (CS) in Pavlov’s experiment with salivating dogs?

A

previously neutral stimulus that after being repeatedly associated with an unconditioned stimulus comes to trigger a conditioned response - the metronome became the CS as the dog learned to associate it with food

Q

Explain the unconditioned response (UR) in Pavlov’s experiment with salivating dogs?

Q

Explain the contributions of Pavlov’s work?

A
  • showed that learning could be investigated experimentally using non-human participants (animals)
  • provided therapies for conditions such as phobias and addictions - can help us unlearn these behaviours
  • behaviour is learnt over a period of time

Q

Explain the contribution of Pavlov’s work in regard to therapy techniques?

A

Techniques based on classical conditioning, such as systematic desensitization and exposure therapy, have been developed to treat a variety of psychological disorders, including phobias and post-traumatic stress disorder (PTSD)

  • in these cases a CR (like fear) can be unlearned by changing the association between a specific stimulus and its response

Q

Explain the little Albert experiment experiment and what took place)?

A

Conducted by John B Watson and Rayner in 1920 and involved a young child being conditioned to fear a white rat - this was done by Watson making a loud noise every time Albert was presented with the rat which would make him cry

  • after repeated pairings Albert began to expect a frightening noise whenever he saw the white rat

Q

Explain how stimuli’s generalisation was observed in the little Albert experiment?

A

Watson observed that stimulus generalization had occurred - after conditioning, Albert feared not just the white rat, but a wide variety of similar white objects as well. His fear included other furry objects including a fur coat and Watson wearing a Santa Claus beard

24
Q

Explain 3 criticisms and ethical issues regarding the little Albert experiment?

A
  • The experiment has very low external validity because it isn’t generalizable to others
  • their interpretations of little Albert’s neutral and fear reactions can be heavily biased - difficult to assess whether their data is reliable
  • caused a young child a lot of stress and discomfort all while already being ill with a condition
25
Q

Explain 2 of the advantages of the little Albert experiment?

A
  • evidence that classical conditioning can occur in humans - builds on skinners work with dogs
  • plays an important role in understanding how phobias are acquired - can help treat them
26
Q

Explain the strengths of classical conditioning, reference its application to treatment of phobias/anxiety - evaluation?

A

Classical conditioning has been applied in the development for the reduction of anxiety associated with various phobias - systematic desensitisation is based on classical conditioning

  • this classical conditioning based approach has been found to be effective for a range of phobais
27
Q

Explain how systematic desensitisation works with reference to classical conditioning?

A

Is a therapy based on classical conditioning and works by eliminating the learned anxious response (CR) that is associated with a feared object or situation (CS) and replacing it with another like relaxation

  • has been found to be effective for a range of phobias
28
Q

Explain a weakness of classical conditioning, reference its appropriateness to learning - evaluation?

A

Because different species face different challenges to survive some relationships between CS and UCS are more difficult to establish

  • idea that classical conditioning may be more appropriate in learning of specific types of association like those important to survival are link to a species evolutionary history
29
Q

Explain what Seligman (1970) proposed and how it links to classical conditioning only being appropriate for some learning?

A

Seligman proposed concept of preparedness which is the idea animals are prepared to learn associations that are significant in terms of their survival needs - (eg associating smell of meat with presence of food) - unprepared to learn associations that are not significant

30
Q

Explain skinners main belief?

A

Skinner claimed that all behaviour is learnt as a result of consequences (such as gaining rewards or punishment) in our environment this is operant conditioning

  • explored this by also testing it on animals
31
Q

Define reinforcement?

A

Anything that has the fact of increasing the likelihood of a behaviour being repeated it can be positive or negative

32
Q

Explain the term positive reinforcement - give an example?

A

Anything that has the effect of increasing the likelihood of that behaviour being repeated by using consequences that are pleasant when they happen

  • eg a dog getting a treat after being commanded to sit
33
Q

Explain the term negative reinforcement - give an example?

A

Anything that has the effect of increasing the liklihood of the behaviour being repeated by removing unpleasant consequences

  • eg doing homework to avoid punishment/detention
34
Q

Define punishment?

A

Has the effect of decreasing the likelihood of the behaviour being repeated by using consequences that are unpleasant - can be positive or negative

  • eg getting a detention for not doing homework
35
Q

Explain the term positive punishment - give an example?

A

Involves applying an undesirable stimulus to weaken a behaviour

  • eg slapping a naughty child
36
Q

Explain the term negative punishment - give an example?

A

Involves taking away a desired stimulus to weaken a behaviour

  • eg taking a teenagers phone away
37
Q

Explain how positive reinforcement was investigated in skinner experiments with animals?

A

Hungry rat was placed in the Skinner box and as it moved around the box, it would accidentally knock the lever which would immediately distribute a food pellet - after a few times the rat would learn to go straight for the lever

38
Q

Explain how negative reinforcement was investigated in skinner experiments with animals?

A

A rat was placed in the Skinner box and would then be subject to unpleasant electric shocks which caused some discomfort, as it moved around the box it would accidentally knock the lever turning the electric off - rat quickly learned to go straight to the lever after a few times

39
Q

Explain 3 problems with using punishment?

A
  • punished behaviour is not forgotten, its suppressed - behaviour returns when punishment is no longer present
  • causes increased aggression
  • does not necessarily guide you toward desired behaviour, reinforcement tells you what to do, punishment only tells you not what to do
40
Q

Explain what the Skinner box is?

A

Created by B.F. skinner and is a box containing a lever or switch which would reward the animal with a food pellet or turn of an electric shock

41
Q

Explain the contribution of Edward Thorndike’s work to the behaviourist approach?

A

Thorndike’s theory of learning emphasised the significance of reinforcement and punishment in shaping behaviour

  • he believed learning occurs when there is a connection between the stimulus and the response - this connection becomes stronger with repetition
42
Q

Explain 3 of the main points of thorndikes work?

A
  • Thorndike’s experimental work with animals particularly his development of the puzzle box provided insights into the role of reinforcement in learning and behaviour
  • his theory has been instrumental in the development of applied behavioural analysis (ABA) - used to treat autism
  • states behaviour followed by a positive consequence is more likely to be repeated whilst behaviour followed by a negative consequence is less likely to be repeated
43
Q

Briefly state the main idea of Thorndike’s theory of learning?

A

states that behavior that is followed by a positive consequence is more likely to be repeated, while behavior that is followed by a negative consequence is less likely to be repeated. This theory is based on the idea that learning is a gradual process that occurs through trial and error.

44
Q

State the meaning of law of exercise?

A

Part of Thorndike’s theory and focuses on how Learning occurs through repetition and practise

45
Q

Explain two strengths of Thorndike’s work?

A
  • has influenced the development of other theories of learning such as skinner operant conditioning and Banduras social learning theory
  • principles of reinforcement and punishment central to his theory are still used in behaviour modification and therapy
46
Q

Explain what acts as the reinforcer in the skinners experiments?

A

The food pellet which is released when the rat accidentally presses the lever

47
Q

Explain how extinction occurs in the skinners experiments?

A

If the food pellets stop, the rat presses the lever a few more times and then abandons it

48
Q

Explain a strength of skinners work with reference to his method - evaluation?

A

Skinners reliance on the experimental method, using controlled conditions to discover a relationship between variables - allowed him to establish a cause-and-effect relationship between the consequences of a behaviour and the future frequency of its occurrence

49
Q

Explain how skinner was able to carefully control variables in his experiments?

A

Through his reliance on the Skinner box - by manipulating the consequences of behaviour (Independent variable) he was able to accurately measure the effects on the rats behaviour (dependent variable)

50
Q

Explain a weakness of skinners work with reference to his reliance on animials - evaluation?

A

Skinners over reliance on non-human animials in his research - means they have little relevance to humans, as humans have few will

  • skinner argues that free will is an illusion and what we believe, are behaviours chosen through free will are actually the product of external influences that guide our behaviours on a daily basis
51
Q

Explain a weakness of skinners work with reference to his limited perspective on behaviour - evaluation?

A

Behaviourists have been accused of ignoring other levels of explanation which emphasise the importance of cognitive factors or emotional states - skinner argued even complex behaviours such as our interactions with the opposite sex or pathological behaviour could be better understood by studying the reinforcement history of the individual

52
Q

Give 3 strengths of the behaviourist approach?

A
  • very scientific - uses experimental method, means it is very replicable
  • has application to real world activities - treatment of phobias (systematic desensitisation)
  • mainly quantitive data which is easy to analyse
53
Q

Give 3 limitations of the behaviourist approach?

A
  • most data obtained is from non-humans - uses rats,dogs and pigeons
  • ethical issues - research methods did not meet ethical guidelines
  • lots of learning can not be explained with classical conditioning
54
Q

Explain skinners work with pigeons for the US military, give the conditioning used?

A

Idea pigeons could be trained to guide anti-ship missiles to their targets - three pigeons in separate compartments in the cone of the missile with each compartment having a lens - the pigeons were operantly conditioned to peck at the target projected on the lens to keep the missile on target

55
Q

Give a strengths of operant conditioning with reference to behavioural treatment - evaluation?

A
  • operant conditioning has been applied to the treatment of behaviours - eg social skills training for offenders
56
Q

Define response?

A

Reaction to a stimulus - could be fear or shaking

57
Q

Define stimulus?

A

Anything internal or external that brings about a response
