Biological

Question 1

Evolutionary influences

Answer 1

-Evolution explains our change in behaviour by saying we have adapted to the demands of our environment over millions of years.
-Darwins theory of natural selection claims that behaviour that increases our chance of survival and reproduction will be naturally seleected and passed on to future generations.

Question 2

Mate selection

Answer 2

-Natural selection explains this by claiming males seek females who look fertile, e.g, young and attractive.
-Women seek males who can provide for them during pregnancy and raising a child, e.g, income.

Question 3

Localisation of brain function

Answer 3

-Different areas of our brain have been identified to have a different function, such as our cerebral cortex, which is the outer layer and is divided into 4 regions.
-E.g, frontal lobe, partietal lobe, occipital lobe, and temporal lobe.

Question 4

Pre-frontal cortex

Answer 4

-The pre-frontal cortex has been linked with aggressive behaviour as it is responsible for helping control our impulsive and aggressive behaviour triggered by the amygdala.
- If it is less active, we may be prone to aggressive and violent outbursts.

Question 5

Neurotransmitters

Answer 5

-States that human behaviour is down to the influence of neurotransmitters.
-The chemical messangers are transmitted via electrical impulses through our nervous system.
-They take action by being released into a synapse as a chemical messagr and stimulating the next neuron by landing on its receptor sites before being released into that neuron.

Question 6

Neurotransmitters

Answer 6

-States that human behaviour is down to the influence of neurotransmitters.
-The chemical messangers are transmitted via electrical impulses through our nervous system.
-They take action by being released into a synapse as a chemical messagr and stimulating the next neuron by landing on its receptor sites before being released into that neuron.

Question 7

Schizophrenia

Answer 7

-Too much or too little of a neurotransmitters can affect our mood and behaviour.
-For example, too much dopaminr is associated with some symptoms of schizophrenia such as hallucinations.
-Antipsychotic medication works by blocking the dopamine receptor sites to lower the amount of dopamine active in the nervous system.
