Approaches Flashcards
What does the behaviourist approach focus on
-studying behaviour that can be observed and measure
- pioneered by John B watson
- rejects introspection as concepts were too vague and unmeasurable
- tried to maintain more control and objectivity so relied on lab studies
- believe all behaviour is learned and all start with blank slate
- animals can replace humans in experiments as basic processes that govern learning are the same in all species
what are the two important forms of learning in the behaviourist approach
classical and operant conditioning
what is classical conditioning
Pavlovs research (1927)
- learning through association eg pavlovs dogs learned to associate the sound of the bell (stimulus) with the food (another stimulus). This shows the neutral stimulus so bell can be a learned conditioned response through association
Before conditioning - food=unconditioned stimulus, salivation=unconditioned response , bell= neutral stimulus , no salivation= unconditioned response
During - bell+food produces salivation = unconditioned response
After conditioning- bell=conditioned stimulus ,salivation=conditioned response
what is operant conditioning
Skinners research (1953)
-a method of learning that used punishments and rewards to modify behaviour
- skinner suggested learning is an active process whereby humans and animals operate on their environment
what is positive and negative reinforcement (with example)
positive reinforcement- receiving reward and praise when a certain behaviour is performed e.g every time rat activated a lever in the box it was rewarded with a food pellet
negative reinforcement - occurs when animal/human avoids something unpleasant and the outcome is a positive experience e.g to avoid unpleasant stimulus (electric shock) rat activated a lever
what is punishment and what does it do
unpleasant consequence of behaviour that decreases likelihood that behaviour will be repeated
what are the ethical issues with skinners research
all though skinners box allowed behaviourists to maintain high degree over their experimental subjects
- animals were housed in harsh cramped conditions
- deliberately kept below natural weight so always hungry
What is a strength of the behaviourist approach? ( well- controlled…)
P- based on well controlled research
E- behaviourists focused on observable behaviour being measured in highly controlled lab setting. They broke down behaviour into basic stimulus and response units so all extraneous variables were removed so cause and effect relationship was established
L- This suggests that behaviour experiments have scientific credibility
what is the counterpoint of the behaviourist approach being based on well controlled research?
P- behaviourists may have over- simplified this learning process
E- by reducing behaviour to simple components they may have ignored an important influence on learning which is human thought (mental processes in learning)
L- Thus suggests that learning is more complex than observable behaviour alone and private mental processes are also essential
What is another strength of the behaviourist approach
P- the principles of conditioning have been applied to real world behaviours and problems
E- e.g operant conditioning is the basis of token economy systems used successfully in institutions like prisons by rewarding appropriate behaviour with tokens that can be exchanged for privileges
L- This increase the value of the behaviourist approach as it has wide spread application
What is a limitation of the behaviourist approach
P- sees all behaviour as conditioned by past conditioning experiences
E- Skinner suggested that everything we do is a sum total of our reinforcement history. Our past conditioning history determined outcome and this ignores any possible influence free will may have on behaviour
L- This is an extreme position and ignores influence of conscious decision making processes on behaviour
Why was Wundts lab significant in the origins of psychology?
-Opened first ever lab in 1879 dedicated to psychological enquirer in a little town called Leipzig, Germany
-marked beginning of scientific psychology
-his aim was to analyze the nature of human consciousness under controlled conditions and his pioneering method became known as introspection
What is introspection?
First systematic experimental attempt to study the mind by breaking up conscious awareness into basic structures of thoughts images and sensations
What was wundts main objective?
To develop theories about mental processes eg language , perception and to do this he used standardized procedures and his co workers recorded experience of various stimuli and divided observations into thoughts,images and sensations (structuralism-isolating structure of consciousness)
What was a strength of Wundts research?
P-His methods were systematic and well controlled(scientific)
E- All introspections were recorded in a controlled lab so possible extraneous variables were not a factor. All procedures were standardised so all participants were tested in the same way.
L- Wundts research can be considered a forerunner to later scientific approaches eg behaviorist approach
