Is your personality written in your DNA and neurons?
In short: This video explores the biological approach to psychology, examining how our most complex behaviors and mental processes are rooted in physical systems. It moves beyond mere observation to look at the underlying mechanics of the human body.
The biological approach operates on the core assumption that human behavior and mental processes have a fundamental biological basis. This perspective contrasts with behaviorism, which focuses on external stimuli, and cognitive psychology, which prioritizes internal mental processing. By looking at the 'hardware' of the human experience, this field investigates how inherited genes influence traits such as intelligence, personality, and mental health, often utilizing twin studies to measure heritability.
The video further breaks down the physical drivers of behavior into three categories: brain structure, where specific areas manage distinct functions (localization of function); neurochemistry, specifically how neurotransmitters regulate mood; and the endocrine system, which uses hormones like adrenaline and oxytocin to influence our responses.
