Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What two factors does the nature-nurture debate concern when explaining behaviour?

    Model answer

    The relative importance of heredity (genetic inheritance) and environment (experience and learning) in determining behaviour.

  2. 2

    Define 'nature' in the context of the nature-nurture debate.

    Model answer

    Nature refers to the influence of inherited genetic factors on behaviour, including genes, hormones, and neuroanatomy.

  3. 3

    How does heredity transmit characteristics from one generation to the next?

    Model answer

    Heredity transmits characteristics from parents to offspring through genes, providing the biological basis for traits and predispositions.

  4. 4

    What does 'environment' encompass in the nature-nurture debate?

    Model answer

    All external influences after conception, including prenatal environment, family, peers, education, and culture.

  5. 5

    What does the nativist position argue about the causes of behaviour?

    Model answer

    That behaviour is primarily determined by innate, inherited factors.

  6. 6

    What does the empiricist position argue about the causes of behaviour?

    Model answer

    That behaviour is primarily shaped by experience and environmental influences.
