Question

Elaborate on physiological correlates of emotions.

Hint:

Polygraph (lie detector) tests don't actually detect lies; they measure these physiological correlates (sweat, heart rate) associated with the stress of lying.

Answer 1

Step 1: Understanding the Concept:
Emotions are not just "feelings"; they are bodily states. When we experience intense emotion, our body prepares for action through physiological changes.
Step 2: Detailed Explanation:
1. Autonomic Nervous System (ANS): - Sympathetic Division: Activated during fear or anger (Fight or Flight). It increases heart rate, dilates pupils, and stops digestion. - Parasympathetic Division: Restores the body to a calm state after the emotional event has passed.
2. Specific Correlates: - Galvanic Skin Response (GSR): Increased sweating leads to better electrical conductivity on the skin. - Hormonal Changes: Adrenal glands release epinephrine (adrenaline) and norepinephrine. - Blood Pressure and Heart Rate: Both rise significantly during intense emotional arousal. - Respiration: Breathing becomes faster and shallower.
Step 3: Final Answer:
These physiological changes provide the energy and physical readiness required to react to emotional stimuli in the environment.
