Anxious Personality Traits: Perspectives from Basic Emotions and Neurotransmitters.

Area of Science:

• Psychology
• Neuroscience
• Psychiatry

Background:

• Rising prevalence of emotional diseases like anxiety and depression.
• Potential link between personality traits and the development of mental illness.
• Personality theories and dimensional emotional theory require further investigation.

Purpose of the Study:

• Review personality and emotional theories.
• Compare emotional and personality dimensions.
• Investigate neural mechanisms linking personality traits, emotions, and neurotransmitters.

Main Methods:

• Literature review of personality and emotional theories.
• Comparative analysis of emotional and personality dimensions.
• Investigation of neuromodulators for anxiety-related personality traits.

Main Results:

• Emotional and personality dimensions show correlations (e.g., extroversion-hedonia, neuroticism-arousal).
• Personality traits are linked to basic emotions (e.g., self-centeredness-disgust, instability-anger/fear).
• Neural correlates identified: dopamine (extroversion), serotonin (introversion), norepinephrine (neuroticism).

Conclusions:

• Personality traits and emotions are correlated and depend on monoamine neurotransmitters.
• Emotional and neurotransmitter regulation offers a pathway for treating personality disorders.
• Findings provide a new perspective on personality traits, emotional diseases, and clinical applications.
