2.1 - Approaches In Psychology (Set C - behaviourist approach) Flashcards
Who established the behaviourist approach, who else contributed what was the overall assumption of the approach?
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
Explain the main assumption of the behaviourist approach?
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)
Explain 3 other assumptions of the behaviourist approach?
- 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
What is the behaviourist approaches stance on ‘nature v nurture’ debate?
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)
What is the behaviourist approaches stance on determinism v free will?
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
What is a problem with the behaviourist approach siding with determinism?
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)
What is a strength with the behaviourist approach siding with determinism?
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
Is the behaviourist approach scientific?
Behaviourist uses scientific methods to investigate ideas - for example forming hypotheses and using methods like experiments - considered scientific
What is a strength of the behaviourist approach being scientific?
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
Explain what classical conditioning is?
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
Explain the work of Ivan Pavlov in 1927?
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)
Explain 3 things Pavlov showed or disscovered?
- 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
Explain the neutral stimulus (NS) in Pavlov’s experiment with salivating dogs?
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
Explain the unconditioned stimulus (UCS) in Pavlov’s experiment with salivating dogs?
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
Explain the conditioned stimulus (CS) in Pavlov’s experiment with salivating dogs?
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
Explain the conditioned response (CR) in Pavlov’s experiment with salivating dogs?
the learned response to the CS it is triggered by the CS - in this case salivating to the sound of the metronome (CS)
Explain the unconditioned response (UR) in Pavlov’s experiment with salivating dogs?
automatic, innate reaction to an unconditioned stimulus, does not require any learning - in the experiment it is dogs automatically salivating in response to food
Explain the contributions of Pavlov’s work?
- 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
What is the law of temporal contiguity?
Idea that if the time between the conditioned stimulus (bell) and the unconditioned stimulus (food) is too great then learning will not occur
Explain the contribution of Pavlov’s work in regard to therapy techniques?
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
Explain the little Albert experiment experiment and what took place)?
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
Give the 5 stimulus’s and responses in the little Albert experiment?
- Neutral stimulus - white rat
- unconditioned stimulus - loud noise
- unconditioned response - fear
- conditioned stimulus - white rat
- conditioned response - fear
