THE BIOLOGICAL APPROACH – KEY ASSUMPTIONS

STARTER � What things do you have in common with your parents? Write down a few ideas on your handout. � Looking at what you have written down, are these things due to biological influences, or the environment? � Highlight in two different colours

WHAT IS THE BIOLOGICAL APPROACH? � The biological approach combines psychology and biology to provide physiological explanations for human behaviour. � Biological psychology tries to explain how we think, feel and behave in terms of physical factors within the body.

NATURE VS. NURTURE With regards to the nature vs. nurture debate, the biological approach falls on the side of ______. VS.

WHAT IS THE BIOLOGICAL APPROACH? The biological approach explains human behaviour in terms of neurotransmitters, hormones, genes and brain structures. What do you already know about these four things? BRAINSTORM

THE STRUCTURE AND FUNCTION OF NEURONS Using your textbook, find 3 types of neurotransmitters and what they are associated with. Write this onto your handout.

OUTLINE 2 ASSUMPTIONS OF THE BIOLOGIAL APPROACH. (4 MARKS) One assumption of the biological approach is the……. . Explain how it works……. Give an example…….

GENETIC EXPLANATIONS Genes interact with one another to produce an effect on behaviour. Genes however, do not control all human characteristics because the environment also has a part to play. We inherit 23 chromosomes from each parent, and it is thought that our genes can account for many of the similarities between family members.

GENETIC EXPLANATIONS �Can you think of a family where many of the members have something in common? �It could be a physical trait (hair, eye colour, height etc) or a personality trait or talent (music, running, annoying laugh etc).

GENETIC EXPLANATIONS Do you think the similarities you have mentioned above are due to genetic or environmental factors? How could genes and environment interact to produce a person who is good at football? What about someone who suffers from depression?
