unit 1 Flashcards
What does the frontal lobe do?
Problem solving
What does the partietal lobe do?
Sensory processes like pain
What does the temporal lobe do?
Responsible for auditory information
What does the occipital lobe do?
Interpreting visual stimuli
Assumptions of biological approach
Evolutionary influences, localisation of brain function, neurotransmitters.
What does the evolutionary influences assumption state?
-Explain human behaviour based on Charles Darwin’s theory of evolution which states species survive through natural selection.
Evolutionary influences biological example
- TRIVERS claimed that the formation of romantic is driven by how each sex has a different level of investment in ensuring their offspring’s survival.
- Females carry offspring so look for male with shelter and high earning capacity.
- Males look for fertile, youthful women to have a baby with.
Localisation of brain function biological assumption
Cerebral cortex can be divided into frontal lobe, parietal lobe, occipital lobe, and temporal lobe. And each part has a specific function
Localisation of brain function biological example.
Wernicke’s Aphasia disorder. Occurs when Wernicke’s area of temporal lobe is damaged. Causes the person to talk in phrases that lack meaning. This is because the temporal lobe is responsible for auditory information.
Neurotransmitters biological assumption
-Neurotransmitters are chemical messengers passed from the presynaptic neuron to post synaptic neuron of a synapse.
- Each neurotransmitter has a different function e.g dopamine controls emotional responses.
Neurotransmitters psychological example
ARON ET AL concluded that dopamine plays a significant role in the formation of romantic relationships because it activates the reward centres of the brain and amplified effect of sex hormones. Shows powerful impact that meeting an attractive mate can have.
Application of evolutionary influences to relationships
TRIVERS claimed formation of romantic relationships driven by how each sex has a different level of investment in ensuring offspring survives. Females look for shelter and money. Men look for youth and fertility
Application of localisation of brain function to relationships
OFC located in the frontal lobe and is involved in impulse control and response inhibition. OFC decided if it’s a benefit for individuals to act on a sexual stimulus depending on rewards given. LITTLE ET AL found that observing beauty raised OFC action
Application of neurotransmitters to relationships
Oxytocin is a hormone which acts as a chemical messenger in the brain. Linked to pregnancy and birth behaviours. Females with high levels of oxytocin are more nurturing to their offspring.
