Core components of emotional impulsivity: A mouse-cursor tracking study.

Area of Science:

• Psychology
• Cognitive Neuroscience
• Behavioral Science

Background:

• Impulsive individuals display altered reward processing (impulsive choice, IC) and impaired action inhibition (impulsive action, IA).
• Emotions significantly influence both impulsive choice and impulsive action, but their precise impact on these behaviors is debated.
• Existing theories propose emotions exacerbate impulsive action or disrupt attention (attentional impulsivity, AImp), but empirical evidence is inconsistent, especially in nonclinical populations.

Purpose of the Study:

• To investigate the interplay between emotions, impulsive action (IA), attentional impulsivity (AImp), and impulsive choice (IC) in a nonclinical population.
• To determine how experimentally elicited positive and negative emotions affect behavioral indices of impulsivity.
• To clarify the role of emotions in modulating attentional control and impulsive behaviors.

Main Methods:

• Two studies were conducted using a nonclinical sample.
• Emotional states were elicited using standardized sets of emotional pictures (positive and negative valence).
• Behavioral measures of impulsivity, including impulsive action (IA), attentional impulsivity (AImp), and impulsive choice (IC), were assessed, potentially using mouse-cursor tracking.

Main Results:

• Elicited emotions significantly altered behavioral measures of impulsivity in the nonclinical participants.
• Emotions were found to exacerbate impulsive behavior primarily by disrupting attentional control.
• Positive Urgency emerged as a key factor influencing inhibitory control.

Conclusions:

• In nonclinical individuals, emotions enhance impulsive behavior through impaired attentional control.
• Emotional impulsivity, particularly Positive Urgency, plays a critical role in regulating inhibitory control.
• Findings contribute to understanding the complex relationship between emotion regulation and impulsive behaviors.
