Understanding the Biological Basis of Behavior

The biological approach in psychology looks at how our genes, brain structure, hormones, and nervous system shape our thoughts, feelings, and actions. It argues that much of human behavior is rooted in our biology.

Key Concepts

• Neurotransmitters: Chemicals like dopamine and serotonin influence mood and behavior.
• Brain Structure: Specific regions of the brain, such as the amygdala or hippocampus, play roles in emotion and memory.
• Genes and Heredity: Genetic inheritance can affect traits like intelligence and susceptibility to mental disorders.

Real-World Impact

Understanding the biological approach helps explain why some people may be more prone to anxiety or why medication can help balance mood disorders.

Why Does This Matter?

By connecting biology with behavior, psychologists can develop treatments for mental health issues and understand the physical roots of psychological phenomena.
