Understanding the Dual Systems Model

Front

What is the Dual Systems Model?

Back

A psychological theory that explains decision-making as a result of two systems: the emotional limbic system and the rational prefrontal cortex.

Front

What role does the limbic system play in decision-making?

Back

The limbic system drives emotional responses and is particularly responsive to rewards, influencing risk-taking behavior.

Front

How does the prefrontal cortex contribute to decision-making?

Back

The prefrontal cortex is responsible for rational thinking, planning, and self-control, helping to regulate impulses from the limbic system.

Front

What is gray matter and why is it important?

Back

Gray matter consists of neuronal cell bodies and is crucial for processing information in the brain, including during development.

Front

How does brain development differ between teenagers and adults?

Back

Teenagers have a more developed limbic system, leading to heightened emotions, while their prefrontal cortex is still maturing, affecting decision-making.

Front

What is the significance of Phineas Gage's case in psychology?

Back

Phineas Gage's accident provided early evidence of the relationship between brain function and personality, highlighting the role of the frontal lobe.

Front

What does it mean for a theory to be 'localized' in brain science?

Back

Localized theories suggest that specific brain areas are responsible for particular functions or behaviors.

Front

What is the importance of understanding brain maturity in adolescents?

Back

Understanding brain maturity helps explain why teenagers may engage in risky behaviors and how their decision-making processes differ from adults.

Front

What is the relationship between the limbic system and emotions?

Back

The limbic system is closely linked to emotional responses, influencing how individuals react to various stimuli.

Front

Why is it important to study both early and modern theories in brain science?

Back

Studying both provides a comprehensive understanding of how brain science has evolved and how past theories contribute to current knowledge.
