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 outlook and nervous system. biological psychologists seek methods that allow them to view mind activity, the development of idea scanning techniques in the past 30 years, much more(prenominal) microscopic methods of studying the brain have been developed. hurtle scans admit taking a series of x-rays and combining them to seduce a comprehensive two or three dimensional testify of the area being scanned. Usually a discolour is injected into the diligent as a contrast material and indeed he/she is placed into a cylindrical machine that supports the pictures. magnetic resonance imaging scans fill the hold of a magnetic field that causes the atoms of the brain to remove their alignment when the magnet is on and emit motley radio receiver signals when the magnet is turned off, a detector reads the signals and uses them to map the social structure of the b rain. PET scans involve administering somewhat radio mobile glucose into the patient, the most active areas of the brain use glucose and radiation detectors can see the hot areas so create 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 remove between beign and malignant tumours e.g. PET scans can overly presentation the brain in action which is useful for psychological research. stock-still this is an extremely costly technique and therefore not advantag eously available for research, also as the p! atient has to be injected with a radioactive substance, the technique can only be apply 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 fit share 100% of their genes, same behaviour is a result of our genes both twins should demonstrate the same behaviour. E.g.
