The emotion-elicited late positive potential is stable across five testing sessions

Area of Science:

• Cognitive Neuroscience
• Affective Science
• Psychophysiology

Background:

• Cross-sectional studies limit understanding of attention to emotion's trait-like nature.
• Longitudinal investigation of neural and behavioral markers is crucial.

Purpose of the Study:

• To examine the stability and trajectory of attention to emotional stimuli.
• To assess the influence of daily affective fluctuations on attention markers.
• To determine if attention markers predict behavior.

Main Methods:

• Used the Emotional Interrupt paradigm across five weekly sessions in 86 individuals.
• Measured behavioral responses (reaction time) and neural responses (Late Positive Potential - LPP).
• Assessed daily positive and negative affect.

Main Results:

• LPP magnitude decreased, but emotional differentiation remained stable or increased.
• Behavioral responses demonstrated stability across sessions.
• Daily affect did not significantly impact LPP or behavior; LPP predicted reaction time.

Conclusions:

• Neural and behavioral markers of attention to motivationally salient cues appear trait-like.
• These stable markers may indicate vulnerability for psychopathology.
• Future research can utilize these markers in studying mental health conditions.
