Approaches, Issues and Debates Flashcards
Define psychology
The study of mind and behaviour, originating from biology, philosophy and physiology
Define approaches and identify them
• Key stances used to explain behaviours and characteristics in humans
• Behaviourist approach
• Social Learning Theory
• Cognitive Approach
• Biological Approach
• Psychodynamic Approach
• Humanistic Approach
Explain the origins of psychology
• Psychology is thought to originate from the work of Wilhelm Wundt, who’s referred to as the father of (modern) psychology
• Wundt pioneered introspection and founded the Institute of Experimental Psychology in Leipzig in 1879 which was the first psychology lab
Outline introspection
• A technique pioneered by Wundt to gain insight into mental processes carried out in his university room
• People were trained to report on their inner experiences (feelings, thoughts and sensations) when presented with a stimulus such as a problem to solve or something to memorise
• They’d report back what they experienced/analysed using a structuralism approach. This refers to breaking thoughts down into the simplest definable components to find out how they fit together to form more complex experiences to uncover the structure of the mind
• Reports couldn’t be replicated so we’re unreliable as everyone’s experience was subjective. However, this technique allowed internal mental processes to be studied and enabled psychology to emerge as a science
Identify and define the major features of science
• Replicability: Can you repeat the setup exactly
• Objectivity: Measurable methods used
• Empiricism: Measurable, objective methods
used. Cannot be deemed unscientific
• Falsification: Can you test the hypothesis
Outline the Behaviourist approach
• Behaviourism emerged at the start of the 20th century, pioneered by John B Watson. It’s credited with developing psychology as a scientific discipline and rejected introspection as concepts were vague and immeasurable
• Key studies include Pavlov (1927), Skinner (1955) and Watson and Rayner (1928)
Identify the assumptions of the behaviourist approach
• All animals are born with a blank slate (tabula rasa) and all behaviours learnt from environmental interaction (experience)
• Not interested in mental processes, only things that can be observed and measured I.e rejection of Wundts work
• Highlighted the importance of control and objectivity (lab studies used)
• All animals learn in the same way (animal studies used)
• Two important forms of learning; operant and classical conditioning
Identify the stances of the behaviourist approach
• Environmentally Determinist
-Behaviour’s determined by stimulus-response
conditioning (CC+OC)
• Nurture perspective
-Humans are born as a blank slate (tabula rasa)
and all behaviour is learnt
• Environmentally Reductionist
-Behaviour’s reduced to stimulus-response
associations
• Nomothetic
-Creates universal laws as behaviours the result
of stimulus-response associations
• Scientific
-Uses lab studies and embraces animal studies
Outline Watson and Rayner (1928)
• Experiment to show the importance of environment and learning on behaviour
• A white rat was shown at the same time as a loud noise behind his head
• Little Albert started to cry at just the rat: the fear response was conditioned
What can Watson and Rayner (1928) be used to support (3)
• The Behaviourist approach
• Pavlov (1927)
• The Behaviourist explanation to explaining phobias including Mowrer’s (1960) two process model
Outline classical conditioning
• Proposed by Pavlov (1927)
• Learning through association (which Pavlov called signalisation) where we learn to associate a neutral stimulus with an (unconditioned) stimulus that already produces a response
• Through regular pairing, the neutral stimulus becomes associated with the unconditioned stimulus and becomes a conditioned stimulus producing a new learned (conditioned) response
Outline Pavlov (1927)
• Aimed to find out if reflex behaviour can be produced in new situations through learning and raised 35 dogs of a variety of breeds in a lab in a sealed room to prevent extraneous variables
• The dogs were strapped to harnesses and had a tube linked to its mouth that drained saliva into a measuring bottle
• Dogs salivated at meat powder and didn’t at a neutral stimulus sound (control). To condition the dog, Pavlov paired these usually 20 times until he presented the dog with the sound and no meat
• The dog started to salivate 9 seconds after hearing the sound and by 45 seconds produced 11 drops of Saliva
• The brain sees the new sound as a signal and links it to a reflex based on experiences, Eg. This explains how animals learnt to hunt and escape being hunted
What issue can be applied to Pavlov’s research
Animal studies
What can the negative EVA of animal studies be applied to
• Behaviourist approach
• Pavlov (1927) /Skinner (1955)
• Animal studies of attachment- Lorenz/Harlow
Outline operant conditioning
The idea of learning through consequences, proposed by Skinner (1938) who was influenced by Thorndike (1905)
Outline Skinner (1938)
• Aimed to administer a reward after an animal performed a desired behaviour to determine how long it would take the animal to start performing said behaviour
• ‘Skinner’s box’ contained a response lever that prompted the release of a food pellet as well as loudspeakers and lights to act as visual and auditory signals and cues.
• The floor was metal and could be electrified to administer electric shocks. Actions to avoid shocks would be negatively reinforced
• Skinner found when a rat realised it received a food pellet by pulling a leaver, the rat kept doing it due to positive reinforcement. Pressing the lever became a learned behaviour due to continuous reinforcement
• Voluntary behaviour is affected by consequences of previous behaviour
Supporting EVA for Skinner (1955) and the Behaviourist approach
• Practical Applications of Token Economy Programmes (TEPs) use positive reinforcement to modify behaviour in a closed setting (eg. Hospitals/prisons)
• Hobbs and Holt (1976) showed TEPs work to reduce antisocial behaviour in a juvenile detention centre
• TS has positive wider application to society showing the value of psychological research
Explain positive reinforcement and provide an example
• Behaviours more likely to occur due to positive consequences
• Cleaning your room as a child with the incentive of extra TV time
Explain negative reinforcement and provide an example
• Behaviours more likely to occur because of avoidance of negative consequences
• Army personnel follow strict rules to avoid disciplinary action
Explain punishment and provide an example
• Behaviours less likely to occur because of negative consequences
• Speeding down a motor way may lead to a monetary fine
Identify 7 extra types of reinforcement
- Primary reinforcement
- Secondary reinforcement
- Continuous reinforcement
- Fixed interval reinforcement
- Variable interval reinforcement
- Fixed ratio reinforcement
- Variable ration reinforcement
Briefly outline Thorndike (1905)
Thorndike put forward a ‘law of effect’ stating any behaviour followed by pleasant consequences is likely to be repeated and any followed by unpleasant consequences is likely to stop
What’s a negative of the Behaviourist approach
The use of animal studies
Outline Social Learning Theory (SLT)
• Pioneered by Albert Bandura who agreed with behaviourists in that behaviour’s learned through direct experience (CC & OC) but proposes that people also learn through observation and imitation of models
• Key research comes from Bandura (1961)
Identify the assumptions of Social Learning Theory (SLT)
• The first principle of behaviour is that all is learned from the environment
• Behaviours learned by consequence and association (OC/CC) and from observing role models through vicarious reinforcement and mediation processes
• No regard for genetics having an influence of behaviour
• SLT’s not strictly behaviourist as it considers cognitive processes as well as behaviour
Identify the stances of SLT
• Soft Determinist
-Behaviours controlled by mediational processes
however individuals can freely choose what
information they attend to
• Nurture perspective
-Behaviours learnt via operant and classical
conditioning
• Reductionist
-Shares elements of behaviourist and cognitive
approaches
• Nomothetic
-Attempts to establish general laws of behaviour
(Eg. Vicarious reinforcement)
• Mostly Scientific
-Establishes scientific methods (Eg. Bandura’s
bobo doll), however, it considers mediational
processes which can’t be directly observed
