Biological Approach Assumptions Assumption 1: Evolutionary influences • theory of evolution has been used to explain how the human mind and behaviour have Changed over millions of years. • This is so that people are adapted to the demands of our individual environments Theory of natural Selection • The idea that any genetically determined behaviour that enhances an individuals chance of survival and reproduction will be naturally selected (ie the genes will be passed onto the next generation) EEA environment of evolutionary adaptiveness • The environment to which any species is adapted and the selective pressures that exist at that time • evolutionary psychologists dont assume that all forms of behaviour are adaptive, the only ones the survival in that individuals. ensure that will assume Particular environment. Assumption 2: Localisation of Brain function. • the principle that certain areas of the brain are responsible for different functions. Cerebal cortex covers the brain and is responsible for higher order cognitive functions. Four lobes ● • Cerebal cortex is divided into 4 regions. frontas, parietal, temporal and occipital frontal lobes 0 thinking and creativity, have been linked to Personalities Parietal lobes. • Sensory infe (pain, temperature, touch) Temporal lobes O memory processing + auditory processing. Occipital lobes • visual processing, recieve info from eyes directly. Localisation of Language 0 Specific areas of the brain are linked to the processing of language Assumption 3: Neurotransmitters Neurons • eletrically excitable cells. ● form the basis of the nervous system • branches at the...

end of each neuron (dendrites) allow each neuron to connect with many others. • A neuron communicates with another neuron at where synapse which is the message is relayed by chemical messengers (neurotransmitters) neurotransmitters are released from presynaptic. vesscles in one neuron and Stimulate or may Inhibit receptors at the post-synaptic receptor in the other neuron. Neurotransmitters and health Play a significant role. Example : too little seretonin is linked to depression, antidepressant medication therefore works by increasing the availability of seretonin at the post-Synaptic receptors High levels of the dopamine neurotransmitter has been associated with schitza phrenia to stop this the drug blocks dopamine activity
