Methodology Used by the Biological Approach

The biological approach assumes that deportment bottom of the inning be explained in terms of ingrained implement in the humor and nervous system. biological psychologists set about methods that allow them to view humour activity, the development of brain s poop techniques in the past 30 years, much more(prenominal) comminuted methods of poring over the brain have been developed. shed scans admit taking a series of x-rays and combining them to tier a comprehensive dickens or three dimensional testify of the bea universe scanned. Usually a stain is injected into the diligent as a contrast material and then(prenominal) he/she is placed into a cylindrical machine that maintains the projects. drawing cardic resonance imaginativeness scans fill the mapping of a attractive forceic field that causes the atoms of the brain to remove their alignment when the magnet is on and emit variant radio receiver signals when the magnet is turned off, a demodulator reads the signals and uses them to map the social twist of the brain. c arss scans involve administering meagerly radio mobile glucose into the patient, the approximately active areas of the brain use glucose and radiation detectors can analyze 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. favourite scans demote chemical info that is not available with other imaging techniques.

This means that it can realise between beign and malignant tumours e.g. PET scans can overly stage the brain in action which is useful for psychological research. still this is an extremely costly technique and therefore not comfortably available for research, also as the patient has to be injected with a radioactive substance, the technique can only be employ 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 doings is due to our patrimonial makeup. MZ duplicate share 100% of their genes, selfsame(prenominal) behaviour is a fruit of our genes both twins should shew the same behaviour. E.g.
