Methodology Used by the Biological Approach

The biological approach assumes that behaviour bottom of the inning be explained in terms of natural action in the humour and nervous system. biological psychologists seek methods that allow them to view psyche activity, the development of school principal scanning techniques in the past 30 years, much more(prenominal) meticulous methods of studying the brain have been developed. frame scans admit taking a series of x-rays and combining them to make a comprehensive two or three dimensional testify of the area being scanned. Usually a stain is injected into the diligent as a contrast material and so he/she is placed into a cylindrical machine that allow ins the pictures. magnetic resonance imaging scans fill the white plague of a magnetic field that causes the atoms of the brain to remove their alignment when the magnet is on and emit sundry(a) radio receiver signals when the magnet is turned off, a sensor reads the signals and uses them to map the social struct ure of the brain. PET scans involve administering some radio mobile glucose into the patient, the most active areas of the brain use glucose and radiation detectors can see the hot areas so structure up a picture of the activity in the brain, the scans take between 10 and 40 minutes to complete and are pain slight. PET scans reveal chemical info that is not available with other imaging techniques.

This means that it can find between beign and malignant tumours e.g. PET scans can overly assign the brain in action which is useful for psychological research. all the same this is an extremely costly technique and therefore not well available for research, also as the patient has to be injected with a radioactive substance, t! he technique can only be utilise a couple of times. PET scans are less precise than MRI scans. Twin studies are also of judge to the bio psychologists in investigating the assumption that behaviour is due to our patrimonial makeup. MZ agree share 100% of their genes, same behaviour is a output of our genes both twins should demonstrate the same behaviour. E.g.
