Approaches In Psychology Flashcards
(107 cards)
what are the origins of psychology?
rene descartes- dualism=
the suggestion that the mind and body are separate from each other.
john locke- empiricism=
the suggestion that all knowledge comes from experience. this influenced the development of the behavourist approach
charles Darwin- evolution=
the suggestion that all human and animal behaviour changes over successive generations. influenced the development of the behavourist approach
what were wundt’s key contributions?
-known as the ‘father of psychology’ who moved psychology from psychological roots to controlled research
-set up the first psychology laboratory in Germany, which was designated to the scientific study of psychological enquiry under controlled conditons
-made the first attempt to analyse the nature of human consciousness and systematically study the mind under such controlled conditions. Developed the method of introspection.
what is introspection?
- a systematic analysis/ study of the mind by breaking up conscious awareness into basic structures of thoughts, images, sensations
-individuald would exam and report on their own mental processes when presented with stimuli or a task (standardised sensory events)
-individuals would then report their resctiond snd these would be analysed using the tridimensional scale of feelings
-isolating the structure of consciousness is known as structuralism
what is structuralism
investigating thoughts, images and sensations seperately
How do wundt’s contributions have practical applications?
- causes the introduction of scientific principles in research
-all introspection were recorded under strict, controlled conditions ensuring they were conducted in the same environment with the same stimulus (standardised procedure)
-experimental method helped pave the way for psychology to emerge as a science alongside the development of other approaches
How is introspection questioned by the fact that introspection relies on non-observable responses?
-participants are unable to comment on unconscious factors relating to their behaviour and are purely reporting on their thoughts, emotions etc
-cant be scientifically measured or physically observed
-makes it extremely difficult to establish general laws for human behaviour as we are purely relying on non-observable responses to draw conclusions from
How is introspection questioned by the fact thhat it relies/ produces subjective data
-is purely based on ones’ personal experiences and perspectives meaning that it heavily produce subjective data
-makes it extremely difficult to establish general rules or laws about human behaviour as each sequence of introspection can be extremely unique
what are the main assumptions of the behaviourist approach?
-suggests that all behaviour is learnt through environments and experuences
-our environmnt provides us with stimuli to which we respond to
-through experience we learn to reposnd to stimuli in particular ways
-behaviourist approach is only interested in studying behaviour that can be observed and measured
-early behavourists rejected the idea of introspection suggesting that it was too vague and difficult to measure
-they tried to maintain more control and objectivity within their research and relied on lab studies in order to achieve this
What is classical conditioning?
learning through association
what is the process of classical conditioning?
1) before conditioning
-unconditioned stimulus —-> unconditioned response
2) during conditioning
unconditioned stimulus + neutral stimulus —-> unconditioned response
3) after conditioning
conditioned stimulus —> conditioned response
what is one trial learning (classical conditioning)?
sometimes an animal/human can acquire a new behaviour in a single pairing of the neutral stimulus and unconditioned stimulus. this tends to happen when the response is severe ad failing to learn could be fatatl
what is extinction and spontaneous recovery (classical conditioning)?
-if the conditioned stimulus is repeatedly presented in the abscence of the unconditioned stimulus the strenght of the conditioned resposne gradually declines and eventually becomes extinct
-if the pairing ever occurs again then the response reappears
what is generalisation (classical conditioning)?
-the stimuli is similar to the controlled stimulus and can also trigger the controlled response
What happened in the key study of Pavlov?
Pavlov investigated classical conditioning in action with dogs: could dogs be conditioned to heavily salivate at the sound of a bell if repeatedly preseted at the same time as they were gives food.
Dogs were individually situated in a laboratory based environment secured within harnesses. A food bowl was positioned before them and a device was employed into their gums to gather saliva produced.
Before the experiment: dogs would salivate in response to the food, but not to a bell when it was rung
During the experiment: the bell was rung whenever food was presented
After many trails: the dogs would salivate to the sound of the bell alone. an association was formed
What are the strengths and weaknesses of the pavlov study?
strength:
-can easily be replicated, it is a lab experiment so a standardised procedure was used, can check for consistency of results
-high internal validity, the IV was dlly controlled by pavlov, can be sure that the DV was completely affecting the IV
weaknesses:
-lacks generalisability, was just animals (dogs) used in the study, cannot be sure if other animals/ mammals (humans) act the same way
–external validity is low, artificial environmet used due to it being a lab experiment, cannot apply to real life as it wasnt a real situation/ environment
-protection from harm, dogs harmed during processes as he was drilled into the mouth, has not fulfilled his duty of care as a psychologist
What happened in the little albert study by watson and Rayner?
-wanted to see whether humans could form phobbias through classical conditioning
-participant was 11 month old Albert whose mother was a nurse at the hospital where they worked
-albert was given a white rat to play with, initially wasnt scared of it
-a metal bar was hit whenever he reached out for the rat to make a loud noise and scare him
-was repeated several times
-albert eventually started crying and screaming when he saw the rat
-response was generalised to other stimuli such as white rabbits, white furred coat, a dog etc
what is operant conditioning?
our behaviour is shaped and maintained by its consequences
learning through consequences (positive or negative)
how does learning via operant conditioning work?
skinner suggested that we can experience reinforcement which increases the likelihood of behaviour being repeated.
POSITIVE REINFORCEMENT:
-we receive a reward for our behaviour, therefore we are more likely to repeat it
NEGATIVE REINFORCEMENT:
-our behaviour helps us avoid something unpleasant, therefore we are more likely to repeat it.
PUNISHMENT:
-we receive an unpleasant consequence of our behaviour, therefore we are less likely to repeat it.
What is behaviour shaping (operant conditioning)?
complex behaviours can be conditioned by reinforcing behaviours which closely resemble the desires response.
what is schedules of reinforcement (operant conditioning)?
a continuous reinforcement schedule (reinforcing the behaviour everytime it occurs) is most effectibe in establishing a particular response
What was the key study of skinner?
-wanted to investigate operant conditioning in action with animals- Could animals (rat or pigeon) learn through the consequences of their actions in three different ways: positive reinforcement, negative reinforcement, punishment
- a rat/ pigeon would be places in a ‘skinner box’ which is a small controlled box with several connecting features. there is a lever which could deliver a food pellet if pressed or pecked. This lever could also be connected to an eletrified grip which if pressed would result in an electric shock or pressign the lever to stop a constant electric shock.
where is positive reinforcement seen in skinners study
pressing the lever and receiving food
where is negative reinforcement seen in skinners study
pressing the lever to stop the constant electric shock
where is punishment seen in skinners study
pressing the lever and receiving a shock
