Psych - Biological
The biological approach - key assumptions
| Question | Answer |
|---|---|
| What is behaviour a result of? | physical parts of your body, e.g. your CNS genes and neurochemistry |
| What affects your body structure? | the genes you inherit |
| What controls your behaviour? | your CNS |
| What is your genetic information a result of? | evolution |
| Over time, genetics create an adaptive advantage which means that those genes gave people characteristics that increased what? | their chances of survival |
| Why is the biological approach scientific? | it examines parts of the body that can be measured e.g. the brain through brain scans |
| How is understanding the brain and the body helpful? | developing treatments for mental illnesses e.g. drugs to treat depression |
| How does the biological approach see influences on behaviour | it states we have no free will over our behaviour and the environment doesn't influence our behaviour |
| How many chromosomes do humans have? | 23 |
| What chromosomes do females have? | XX |
| What chromosomes do males have? | XY |
| What is neuroanatomy? | the physical structure of the brain |
| How many lobes does the brain have? | 4 |
| How many hemispheres does the brain have? | 2 |
| Which lobe of the brain is associated with aggression? | frontal |
| Which hemisphere of the brain is associated with language? | left |
| Which part of the brain is involved with processing memory and emotional information? | the limbic system |
| What is your 'fight or flight' system? | it detects threat and sends a signal to your body to react ( fight or run away) |
| What is neurochemistry? | changes in chemicals in your body that can result in a change in your behaviour through neurotransmitters or hormones |
| Which hormones is linked to stress? | cortisol |
| Which hormone is linked to aggression and male development? | testosterone |
| Which neurotransmitter is linked with mood and low levels of it can lead to depression? | Seretonin |
| What is sexual selection? | people with good genes are more appealing and attractive and more likely to pass genetics to the next generation |
| What are the 2 biological assumptions | Behaviour is influenced by central nervous system (CNS), genes and neurochemistry. Behaviour is a product of evolution. |
