Overview
This lecture introduces biological psychology, exploring its definition, key concepts, and how biology influences human thought and behavior.
Introduction to Biological Psychology
- Biological psychology studies the connection between biological processes and psychological behavior.
- It examines how the brain, neurotransmitters, and genetics affect behaviors, feelings, and thoughts.
- This field is also known as biopsychology or psychobiology.
Key Areas of Study
- Focuses on how the nervous system and brain structure influence behavior.
- Explores the role of hormones and neurotransmitters in mood and action.
- Studies genetic influences on psychological traits and disorders.
Methods in Biological Psychology
- Uses experiments, brain imaging, and case studies to link biology with behavior.
- Employs techniques like EEG, fMRI, and PET scans to study brain activity.
Importance and Applications
- Helps explain mental health disorders through biological causes.
- Informs drug development and therapeutic interventions by targeting brain chemistry.
- Bridges psychology with other sciences like biology, neurology, and genetics.
Key Terms & Definitions
- Biological Psychology — the study of how biological processes affect psychological functions and behavior.
- Neurotransmitter — a chemical that transmits signals across synapses between neurons.
- Nervous System — a network of cells that carries information to and from all parts of the body.
- Hormones — chemicals produced by glands that influence behavior and bodily processes.
Action Items / Next Steps
- Review course textbook chapters on biological psychology.
- Familiarize yourself with main brain structures and their functions.
- Prepare for a quiz on key biological terms and methods.
