The Biological Approach: assumptions of the approach and applying the assumptions to the formation of relationships

  • 3 things to know
  • AS Unit 1

Overview

The three biological assumptions, evolution, localisation of function and neurotransmitters, and how each explains who we are attracted to and how relationships form.

Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    Name the three assumptions of the biological approach.

    Model answer

    Evolutionary influences, localisation of brain function, and the action of neurotransmitters.

  2. 2

    Explain what is meant by an evolutionary influence on behaviour.

    Model answer

    A behaviour that helped ancestors survive and reproduce was passed on genetically, so it persists today as an inherited adaptation.

  3. 3

    Whose theory of natural selection underpins the evolutionary assumption, and in what year was it published?

    Model answer

    Charles Darwin's, in On the Origin of Species in 1859.

  4. 4

    Why does the evolutionary assumption treat a widespread fear of snakes and spiders as adaptive?

    Model answer

    Ancestors who avoided venomous animals were more likely to survive long enough to reproduce, so a readiness to fear them was inherited.

  5. 5

    Define localisation of function.

    Model answer

    The principle that specific areas of the brain are responsible for specific behaviours and mental processes.

  6. 6

    Which brain area is associated with the production of speech, and where is it found?

    Model answer

    Broca's area, in the left frontal lobe.
