the thress assumptions of the biological approach:
evolutionary influences
localisation of brain function
neurotransmitters
the evolutionary theory explains how our mind and behaviour has changed over time as we adapt to our environment
evolutionary influences= Darwins theory of natural selection and genetically determined behaviour which enhances the chance of survival and reproduction will be naturally selected and passed on
evolutionary influences= mate selection to maximise passing on our genes, we seek relationships with individuals with certain traits to enhance successful reproduction
localisation of brain function= certain areas of the brain are responsible for different functions
the cerebral cortex is the outer layer and divided into four regions or 'lobes'
the lobes:
frontal lobe
pariental lobe
temporal lobe
occipital lobe
frontal lobes are involved with thinking
parietal lobes recieve sensory information
temporal lobes are responsible for memory and auditory information processing
occipital lobes are concerned with visual information
specific areas of the brain are linked with aggressive behaviour
