Approaches to psychology Flashcards

What were the assumptions of the behaviourist approach?
interested in studying behaviour that can be observed and measure
Why did John Watson reject introspection?
(behaviourist)
Hard to measure as it was based on processes of the mind that cannot be viewed or proved
What were the ethical issues associated with the behaviourist approach?
animals housed in harsh, cramped conditions and deliberately kept under weight
What is classical conditioning?(behaviourist)
Where a behaviour is learned through association
What is the three stage process of classical conditioning?(behaviourist)
Before conditioning
During conditioning
After conditioning
What does Pavlov’s experiment show and how was the experiment carried out?(behaviourist)
Pavlov’s experiments show how classical conditioning is applied to animals. The experiments consisted of attaching a tube to a dogs salivary glands. He would present the dogs with food(unconditioned stimulus) and ring a bell at the same time (neutral stimulus). The result was that through association when the dog would hear the bell it would salivate(conditioned stimulus) as it associates the sound of bell with food.
What does operant conditioning state?(behaviourist)
Behaviour is shaped by consequence.
What were the three aspects of operant conditioning and what they consist of?(behaviourist)
Positive reinforcement: receive reward when certain behaviour performed
Negative reinforcement: animal or human avoids something unpleasant by doing act
Punishment: unpleasant consequence of behaviour such as being yelled at
What does the skinners box test test and how is the experiment carried out? (behaviourist)
Tests operant conditioning. Rat was placed in box and by pulling lever it learned it would release a reward (food). Also discovered if lever was pulled it would avoid an unpleasant electric shock. (shows both negative and positive reinforcement)
What are positive evaluations of the behaviourist approach?
well controlled research (by breaking down behaviour into basic stimulus removed other variables creating cause and effect relationship)
Have been applied to real world behaviour problems (token economy systems used in prisons and psychiatric wards where you receive tokens for good behaviour)
What are the limitations of the behaviourist approach?
Didn’t take into account other influences on learning (“private mental processes” make things more complex)
Sees all behaviour as conditioned from past experiences (ignores free will effect on behaviour and ignores influence of conscious decisions making decisions as well as disorders -skinner suggested everything we do is the sum of our conditioned history- )
What are the assumptions of the Cognitive approach?
The internal mental processes should be studied, these processes are private and so are studied indirectly via making inferences about what’s happening inside mind (thinking, memory, perception)
How are theoretical and computer models used in the cognitive approach?
Theoretical models: are used to visualise how information goes through the brain in a sequence ( input, storage, retrieval) referencing that out brains work similarly to computers
Computer models: involve programming a computer to see if computer develops a similar response to a human
USED TO DEVELOP THINKING MACHINES AND AI
What is soft determinism?
The view that human behaviour is determined by internal and external factors with free will
What is hard determinism?
views say all our behaviour is determined by factors other than our will e.g genes, conditioning
What did Bronca discover about the brain
Realised damage to the frontal lobe (Broncas area) can alter speech production
What do FMRI’s and PET scans allow (cognitive)
allow systematic observation (allows data to be collected accurately)
What research did Buckner and Peterson carry out (cognitive)?
research involving episodic and semantic memory, saw how different types of long term memory were located on opposite sides of the prefrontal cortex as well as central executive (working memory) in similar areas
What did scanning techniques help to recognise? (cognitive)
Helped to recognise mental disorders and finding links in how they process unpleasant emotions ( OCD and Para hippocampal gyrus)
How have computer models been applied to real life situations? (cognitive)
have been designed to read the brain to create a mind mapping techniques known as brain fingerprinting
also analysis of brain waves to see if eyewitnesses lie in court
What is schema? (cognitive)
Schema is the packages of ideas and information developed through experience, acts as mental framework for interpretation of incoming information
What are positive evaluations of the cognitive approach?
+ uses objective scientific methods
uses lab studies which are highly controlled and produce reliable, objective data also the emergence of cognitive neuroscience where both biology and cognitive psychology have come together
What are the limitations of the cognitive approach?
- uses objective scientific methods- suffers from being to abstract and theoretical
relies upon the inference of mental processes rather than direct observation on behaviour and lacks external validity
-machine reductionism
What specifically were the stages of classical conditioning? (behaviourist)
Before Conditioning
Neutral Stimulus - Bell. No conditioned response
Unconditioned Stimulus - Food
Unconditioned Response - Salivation
During Conditioning
Neutral Stimulus - Bell
Unconditioned Stimulus - Food
Unconditioned Response- Salivation
After Conditioning
Conditioned Stimulus - Bell
Conditioned Response- Salivation
