Psychology Assumptions
PY1: Approaches to psychology Revision
Biological approach
Outline two assumption of the biological approach. [4]
One assumption of the biological approach is that the behaviour can be explained in terms of different areas of the brain. This is because many different areas of the human brain have been identified as certain functions. The cerebral cortex is divided into four lobes. The most important is the frontal cortex/lobe, as this is responsible for fine motor movement and thinking. Another lobe is the occipital lobe which is responsible for processing sensory information. For example, if someone was about to be poked in the eye, the occipital lobe will sense and send the information to the brain through the central nervous system(CNS) telling it to react by closing your eyes immediately. Another assumption is that behaviour can be explained in terms of the neurotransmitters. They are different types of nerves (neurone) in our system which carries information throughout our body and brain. They do so through synapses, this is where the message is relayed by chemical messages. For example, when you take painkillers the morphine will follow the bodies’ normal pain relievers. The nerve cell communicates with each other from across the synapse using the chemical messengers (neurotransmitters). The serotonin (NT) will then take effect which will change our mood and feeling.
Describe Selye’s GAS model. [8]
Hans Selye research, such as the study of ‘the facing page’ led him to conclude that when animals are exposed to stressful situation, they display a universal response to all stressor. He called this general adaptation syndrome (GAS). To prove his theory, Selye’s came up with three stages that’s leads to illness, thus leading stress to illness- stress can result in a decrease of physiological resource, which lowers the organism’s resistant to infection. First stage Selye’s proposed, was the alarm reaction. This is when the stressor recognised and response
