The Biological Assumptions Flashcards
Localisation of brain function, Neurotransmitters, Evolutionary influences
Name the three biological assumptions
Localisation of brain function, neurotransmitters, evolutionary influences
Name the four lobes
Frontal, temporal, parietal, occipital
Key terms: frontal lobe
Personality, reasoning, problem solving, planning, impulse control, Broca’s area = language, thought to speech
Key terms: temporal lobe
Memory formation and retrieval, auditory processing, facial recognition, Wernicke’s area = language, understanding and producing speech
Key terms: parietal lobe
Somatosensory processing = touch, pain, temperature, body position. Spacial awareness
Key terms: occipital lobe
Visual processing, distance and depth perception, colour determination, object and shape recognition
Psychological example(s) for localisation of brain function
Phineas Gage and HM
Which lobe did Phineas Gage damage and how?
Frontal lobe, iron rod through head
Which lobe did HM damage and how?
Temporal lobe, surgically removed due to epileptic seizures
What are neurotransmitters?
Chemical messengers that diffuse across a synapse
Describe how neurotransmitters work
Neurotransmitters are electrical impulses released from the presynaptic neuron, converted to chemical messengers and diffuse across synapse, converted back to electrical impulses at postsynaptic neuron
Psychological example for neurotransmitters
Excess levels of dopamine can lead to schizophrenic behaviour
Psychological example(s) for evolutionary influences
Phobia of the dark and mate selection
Who found that mate selection was universal and a result of evolutionary influences?
Buss
