AP Psychology Practice Test

What is the focus of behavior genetics?

1. Investigating animal behaviors in natural habitats

2. Understanding chemical imbalances in the brain

3. Examining the influence of genetics and environment on individual differences

4. Studying the structure of the brain and its functions

The correct answer is: Examining the influence of genetics and environment on individual differences

The focus of behavior genetics is primarily on examining how both genetics and environmental factors contribute to the variations observed in individual behaviors and traits. This area of study seeks to understand the interactions between an individual's genetic makeup and the surrounding environment, which together influence a wide array of psychological characteristics and behaviors. By analyzing these components, behavior genetics helps to shed light on the heritability of traits and the extent to which they are shaped by environmental influences, allowing for a more comprehensive understanding of human behavior. In contrast, the other options address different areas of psychology that do not center on the interplay of genetics and environment. Investigating animal behaviors in natural habitats pertains more to ethology, while understanding chemical imbalances is related to neuropsychology and psychiatric conditions. Studying the structure of the brain and its functions aligns more closely with neuroscience. Each of these fields contributes valuable insights but does not specifically focus on the genetic and environmental influences that behavior genetics investigates.
