Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    State the central assumption of the biological area.

    Model answer

    Everything psychological is at first biological, so behaviour and experience can be explained by the body's physical structures and processes.

  2. 2

    Name four biological factors used to explain behaviour in this area.

    Model answer

    Genes, brain structure, neurotransmitters and hormones.

  3. 3

    Why does the biological area make heavy use of animals?

    Model answer

    Animals share physiological systems with humans and can be studied under invasive conditions that could never be used with people.

  4. 4

    What is meant by localisation of function?

    Model answer

    The idea that particular psychological functions are carried out by particular regions of the brain.

  5. 5

    Define brain plasticity.

    Model answer

    The brain's capacity to change its structure and function in response to experience.

  6. 6

    Why is the biological area described as determinist?

    Model answer

    It treats behaviour as the inevitable outcome of physical processes such as genes and neural activity, which leaves little room for choice.
