• other psychologists suggests that the influence can operate in an other direction. neuralplasticity is an example as the brain can recognise itself making new connections. it is a term which describes the changes of structure in the brain as a result of life experience. maguire 2000 investigated hippocampus size of taxi drivers in london and found that it has a much larger capacity . concluding that being a taxi driver has an impact on the hippocampus

• psych knowledge has deepened so become more complex and some beleive that the distinction is meaningless and accepted that they dont act independently and how both are essential for behaviour. psychopathology both genetic predisposition and environment needed for a disorder to develop. tinerai 2014 investigated genetic and psych trigger. 19000 finnish children and found high levels of dysfucntional parenting from adoptive and bio parents strongly associated with schizoprenia. shows best explained by the interaction
