• What does the "nature" side of the debate argue?

  Behavior results from innate biological influences
• What does the "nurture" side of the debate argue?

  Behavior is shaped by environmental factors
• What is the interactionist approach in the nature-nurture debate?

  Both genetic and environmental factors influence behavior
• What is meant by a heritability coefficient?

  Numerical value indicating genetic trait influence
• What role do twin studies play in the nature-nurture debate?

  Compare concordance rates to estimate genetic influence
• Give an example of a theory that supports the "nature" side.

  biological approach, such as genetic explanations of mental illness (e.g., schizophrenia linked to genes).
• Give an example of a theory that supports the "nurture" side.

  behaviorist approach, such as classical and operant conditioning, which explains behaviour through learning.
• What is an example of an interactionist explanation in psychology?
