THE COGNITIVE APPROACH
~BASIC ASSUMPTIONS~
Mental processes are ‘private’ and cannot be observed
Between stimulus and response, there are complex mental processes
~SCHEMAS~
A schema is a ‘packet of information’ that helps us organise and interpret information
Babies are born with simple motor schema for innate behaviours (e.g. grasping and sucking)
Schemas develop and evolve with experience. They become more detailed and sophisticated
They are useful by helping us take shortcuts in thinking
However, they can lead to faulty conclusions and unhelpful behaviours
~BUGELSKI & ALAMPAY (1962) - THE RAT MAN~
Two groups shown a sequence of pictures, either of different faces or different animals. Both were then shown an ambiguous figure.
Participants who saw a sequence of faces were more likely to perceive the figure as a man, whereas participants who were shown a sequence of animals were more likely to perceive the figure as a rat
~THEORETICAL AND COMPUTER MODELS~
One important theoretical model is the information processing approach, which suggests that information flows through the cognitive system in a sequence of stages
Cognitive processes include the input, storage and retrieval of information (similar to a computer)
Such computational models of the mind have proved useful in the development of artificial intelligence
~THE EMERGENCE OF COGNITIVE NEUROSCIENCE~
Scientific study of the influence of brain structure on mental processes
Advances in brain scanning technology means scientists have been able to describe the neurological basis of mental processing
Useful on establishing the neurological basis of some disorders
EVALUATION
→ IT ACCOUNTS FOR THE INFLUENCE OF BOTH NATURE & NURTURE ON BEHAVIOUR
One strength of this approach is that it can be praised for applying both nature and nurture to explanations of behaviour.
Nature is shown as we are born with the ability to perform mental processes (e.g. schemas). Nurture is shown as these mental processes can be shaped by the environment.
Research today argues that behaviour can best be explained using both nature and nurture together.
Therefore, as this approach focuses on the influence of both nature and nurture, it increases the ecological validity of the approach.
→ IT IS MACHINE REDUCTIONIST
Another strength of the cognitive approach is that it is reductionist, which is praised for forming the basis of scientific research.
This is due to the fact that often the investigations use scientific testing.
For example, the cognitive approach breaks human behaviour down to computer models.
These findings increase the scientific credibility of the approach, as results supporting these conclusions were produced as a result of a scientific investigation.
→ IT IS SOFTLY DETERMINISTIC
One limitation of the cognitive approach, is that it is deterministic.
For example, this approach believes that behaviour is caused by internal mental processes that have been formed in the past.
This approach can be criticised as it ignores the influence of conscious decision-making processes on behaviour.
This leads to a lack in ecological validity.
→ IT IS NOMOTHETIC
Another limitation of the cognitive approach, is that it overlooks the richness of human experience.
In this approach, research has been conducted into the multi-store model for memory.
The lab studies used to conduct this research lack external validity, which makes it difficult to generalise the findings outside of the research environment.
