areas Flashcards
whats is the main focus of the cognitive area?
the cognitive area focuses on the way our brains processes information.
the cognitive area covers many areas like memory, perception, language, thinking and attention.
what are the key assumptions of the cognitive area?
information processing affects our behaviour.
Our brains operate like a computer – they rely on input, they process information and this leads to an output (behaviour)
We can make assumptions about what is happening in our brain based on external observations of behaviour
what are strengths of the cognitive area?
Can help us understand how we think and process information
Can have useful practical application in schools, crime etc.
It favours the scientific method, so research is usually well controlled and has high internal validity.
Because research is high in internal validity and often uses quantitative data, this area of psychology is high in credibility.
what are weakness of the cognitive area?
A scientific approach can mean that some studies lack ecological validity because they take place in lab conditions
Lab experiments also increase the likelihood of demand characteristics.
Whilst there have been technological advances, there are still limits to the extent to which we can understand internal mental processes. So research is often limited methods such as self report which might lack validity.
Models of information processing aim to generalise to everyone, but are often overly reductionist.
what core studies link to the cognitive area?
Loftus and Palmer (1974) Eyewitness testimony
Grant et al. (1998) Context-dependent memory
how does Loftus and Palmer link to the cognitive area?
links to information processing because Loftus demonstrates that input –in this case he verb used to describe ‘contacted’ can affect our perception of speed travelled.
how does Grant et al. link to the cognitive area?
links to the area because Grant demonstrates that information is easier to recall when the recall conditions match the storage conditions. This shows that the way in which we input information affects our ability to retrieve information.
what is the main aim of the biological area?
To understand how physiological factors impact our behaviour
what are the key assumptions of the biological area?
Our behaviour is affected by genetics, brain structure, hormones and neurotransmission
Internal factors affect our behaviour
what are the strengths of the biological area?
This area favours scientific methods, making it high in internal validity, reliability etc. It is also possible to identify a cause and effect relationship between variables.
The scientific method give the biological area increased credibility
It is easy to test or replicate, which is a key feature of scientific enquiry.
Research in this area is benefitting from new technology so we are developing a greater understanding of how our brain actually works. Neuroscience is one of the most rapidly advancing areas of psychology
what the weaknesses of the biological area?
Whilst there have been technological advances, there are still limits to the extent to which we can understand biological influences on behaviour. A great deal of biological research is correlational so cause and effect relationships can only be inferred, reducing the validity of the area.
Biological variables are difficult to isolate from the effects of nurture and environment, so this can affect the internal validity of research.
Explanations from the biological perspective are often theoretically reductionist in that they only consider biological factors. This makes them too simplistic.
what core studies link to the biological area?
Sperry (1968) Split brain study
Casey et al. (2011) Neural correlates of delay of gratification
how does Sperry’s study link to the biological area?
researched brain function. Brains function is central to the biological approach. Sperry found that each hemisphere of the brain is responsible for different function. He also focused on contralateral function and the role of the corps callosum.
how does Casey’s study link to the biological area?
linked to brain function. Casey found that specific structures in the brain are responsible for delay gratification – ventral striatum & Inferior frontal gyrus
what is the main aim of the developmental area?
To understand how our behaviour/cognition changes as we age and develop over time
