Outline principle P of PACT
- Patterns of behaviour can be inherited because there are genetically based.
- - This means that behaviour can be explained by genetic inheritance, although this is rarely the full explenation since genetic inheritance should be seen as genetic predisposition which can be affected by environmental factors.
Outline principle A of PACT
- Animal research can provide insight into human behaviour
- - This means that researchers use animals to study physiological processes because it is assumed that most biological processes in non-human animals are the same as in humans. One important reason for using animals is that there is a lot of research where humans cannot be used for ethical reasons.
Outline principle C of PACT
- Cognitions, emotions and behaviours are products of the endocrine system and the nervous system.
- - This means that our cognitions (mental actions), emotions and behaviours are products of the anatomy and physiology of our nervous system and endocrine system.
Outline T of PACT
- There are biological correlates of behaviour.
- - This means that there are physiological origins of behaviour such as neurotransmitters, hormones, specialized brain areas, and genes.
What is localization of function?
- Localization of function is that different parts of the brain do different things.
- The main principle of localization of function is that psychological functions are located in specialized areas and therefore damage to the relevant areas cause drastic losses of the functions.
What are the two main hemispheres functions?
- Left – logic, problem solving, maths, and language, controls RHS of body
- Right – creativity, emotion, beliefs controls LHS of body
What are the functions of the four lobes?
- Occipital – vision
- Parietal – higher senses and language functions
- Frontal – reasoning, problem solving, judgement and creativity
- Temporal – perception, hearing (sound recognition), memory and meaning.
