Biological Assumptions Flashcards
(19 cards)
What is the first assumption of the Biological approach?
Evolutionarily influences
What does evolutionary influences claim their theory is?
That we change or adapt to the demands of the environment in order to enhance the chance or survival
What is natural selection?
Natural selection is when genetical behaviours help increase the chance of survival so are then passed down to the next generation
What is an example of natural selection?
Alltrustic behaviour is where a parent will risk their lives if their offspring is in danger in order to save them. This is adaptive behaviour because it has been genetically passed down to increase chance of survival
What is an example in phycology of evolutionary influences?
Aggression is used to gain power, status and resources when you haven’t got any. This increases the chance of survival and therefore is passed to the next generation
What is EEA
Environment of evolutionary adaptiveness
What is the explanation for the evolvement of the brain according to EEA
The brain has evolved and adapted due to the social complex of today allowing us to form better relationships and have a higher chance of survival
What is the second assumption of the biological approach?
Localisation of brain functions
What does localisation of the brain claim their theory is?
The way we behave and act is due to the areas of the brain. The cerebral cortex covers the brain. The cerebral cortex has four lobes that are responsible for the higher order
What are the four lobes of the cerebral cortex called?
Frontal
Temperol
Pariental
Occupational
What is the frontal lobe responsible for?
Creativity and thinking which is linked to our personality
What is the occupational lobe responsible for?
Visual information directly from the eye
What is the pariental lobe responsible for?
Sensory information e.g. Temperature and pain
What is the temporal lobe responsible for?
Storing memory information
Give an example in psychology for localisation of the brain.
Broca studied 8 patients who suffered with speech production and discovered there was a damage to the brain in a specific area now known as the broca area in the left hemisphere this is in the frontal lobe and is responsible for speech production
What is the third assumption of the biological approach?
Neurotransmitters
What does the neurotransmitters assumption claim their theory is?
Neurons are based in the nervous system. They connect all together with the help of dendrites. They relay a message using a chemical message known as neurotransmitters which are in the pre-synaptic veischles. They stimulate or inhabit one Neuron through the other neuron it’s connected to
Using the example of depression explain how the neurotransmitters effect this.
Depression is caused by low levels of seretonin to change this you block up the uptake of seretonin to increase the amount of seretonin in the synapse
Using the example of schizophrenia explain how neurotransmitters effects this.
Schizophrenia is found to occur with high levels of dopamine which means to prevent this we must bind and stimulate temporarily the receptors using medication in order to disassociate the transmission and lower the levels of dopamine to reduce the symptoms.
