Biological approach Flashcards
What are the main assumptions of the Biological approach?
Human behaviour is made up of our genetic makeup, an understanding of brain structures can explain behaviour, and humans have biologically evolved but still share common features with animals.
What are monozygotic twins?
Identical, come from one (mono) egg.
What are dizygotic twins?
Fraternal, come from two (di) eggs.
Define concordance rate.
The amount of twin pairs or other genetically related people who show a certain feature or illness.
Define genotype.
Genes present within each of the cells.
Define phenotype.
The actual characteristic a person displays.
How does a genotype develop into a phenotype?
Environmental influence.
Give some examples of psychological characteristics influenced by genetic factors.
Intelligence, Schizophrenia, OCD etc.
State the purpose of excitatory neurotransmitters.
Trigger nerve pulses in receiving neuron and stimulate action in the brain.
State the purpose of inhibitory neurotransmitters.
Inhibit nerve impulses in order to calm the brain and balance moods.
Order these by size largest first: Hemispheres, Lobes, Cerebrum, Cerebral cortex.
Cerebrum, Cerebral cortex, Hemispheres, Lobes.
State the function of the Parietal lobe.
Sensory information - Touch, Temperature, Pain.
State the function of the Occipital lobe.
Visual information processing.
State the function of the Temporal lobe.
Hearing and memory.
State the function of the Frontal lobe.
Speech, thought and learning.
What makes up the endocrine system?
Hormones and glands.
Order these steps: Endocrine glands, Release hormones, Target cells, Brain, Bloodstream, Physiological response, Receptors.
Brain, Endocrine glands, Release hormones, Bloodstream, Target cells, Receptors, Physiological response.
What was Buss’ study?
Buss studied 37 different cultures and found universal similarities in human mate choice. Women wanted mates who could provide for their offspring. Men wanted mates that were young and attractive which is an indication of fertility and reproductive value.
