- Biological Assumptions
- Neurotransmitters
- Cells that are electrically excitable and form the basis of the nervous system. One neuron communicates with another neuron at the synapse, where a message is passed by a chemical messenger; a neurotransmitter. They either stimulate or inhibit the receptors of the other neuron
- Examples of neurotransmitters; Serotonin- controls mood, apatite and sleep, low levels found in people with depression. dopamine- involved in pleasure, movement and memory, high levels can contribute to schizophrenia.

- Localisation of Brain Function
- Refers to the abilities such as producing and understanding language that are controlled by specific areas of the brain. e.g. Frontal lobe- executive function; money, maths thinking. Occipital lobe- visual cortex. Parietal lobe- sensory cortex, sensory information.
- Phineas Gage; Tamping iron through left side of cheek, suffered damage to the left side of his frontal lobe. Became increasingly aggressive and violent after the accident, became a drunk unable to hold down a job.

- Evolutionary Influences
- Evolution is a process in which it is believes that different kinds of living organisms are said to have developed from different forms during the history of the earth.
- Charles Darwin's Theory of Natural Selection
- Said that characteristics that give the animal a greater chance of survival and reproduction are adaptive.
- Environment of Evolutionary Adaptiveness
- Psychologists arge that humans are adapted to face the environment that out ancestors would have faced.
