approaches Flashcards
what are the assumptions of the cognitive approach?
cognitive processes shape behaviour
Human minds and computers process information similarly
Theoretical models explain how information is processed
Schema can affect the way information is processed
what do cognitive psychologists believe?
that internal mental processes can and should be scientifically tested/
what is an inference ?
an act of drawing conclusions from evidence and reasoning to assume how something is working
what the evaluation for inferences
One issue is that the inference may not be correct
Possible low ecological validity tasks given may not reflect normal mental process functioning because it is carefully measured in Lab environments
Often relies on self reporting-can lack reliability and validity as people may lie or inaccurately record their processes accurately
what is a schema
A mental structure that represents an aspect of the world
what is the computer analogy
Cognitive psychologists often compare the human brain to a computer. It compares how we take information from our senses (input) store or change it (process it) and then behave a certain way (output).
what are theoretical models?
models that depict a series of stages and explain the process of a mental process
what is the evaluation for theoretical models?
Theoretical models are strengthened that certain stages and aspects can be tested individually and examined in detail through inferences
However, inferences are never 100% accurate
what are examples of brain scans
fMRI (function magnetic resonance imaging)
PET (positron Emission Tomography
what does brain scans involve
Involves scanning the brains of “normal” individuals and comparing them to people who have brain damage. They are usually asked to do a task during the scan. This enables inference to be made about how mental processes work.
what are the evaluation for brain scans
Tulving found using MRI that different types of long term memory may be located at different.
what are the strengths of the cognitive approach
Is highly controlled and rigorous in its methods. Uses lab experiments which makes it credible and scientific. However, we have to make inferences which cannot be 100% trusted. Strength
Is very applicable to every day life. There is lots of real life application for memory so this could be expanded to other thought processes which the cognitive psychology approach studies
However, there are many artificial tasks used, this lacks external validity.
Can be used for AI technology as the discoveries made can be important for AI research
Less determinist
determinist (can find a cause for every behaviour)
They believe that aspects of the brain guide as in the right decision
what are the weaknesses of the cognitive approach
Machine reductionist: it reduces the brain to a more simpler computer. It is too simple to include all aspects of the brain. Won’t have a full understanding of the brain.
what is the biological approach
The biological approach combines biology and psychology.
what do biological psychologists believe
in giving physiological reasons to behaviour
what are the assumptions of the psychological approach
Everything psychological is biological first
Neural structures and neurochemistry shape behaviour
Genes and hormones also shave behaviour
The mind lives in the brain.
what are genes?
Are a set of instruction for the growth and development of every cell in the body
We get them from parents
Are packaged in bundles called chromosomes
what is a phenotype?
They way genes are expressed
