Individual differences in alexithymia modulate cognition-emotion interactions in daily life ongoing experiences

Area of Science:

• Psychology
• Cognitive Neuroscience
• Affective Science

Background:

• Individual differences significantly influence thoughts and emotions.
• The interplay between thought and emotion in daily life is not well understood.
• Alexithymia, characterized by atypical emotional awareness, serves as a valuable trait for studying these interactions.

Purpose of the Study:

• To investigate the dynamic relationship between thought patterns and affective states in naturalistic settings.
• To examine how alexithymia modulates the connection between thoughts and emotions.
• To identify distinct dimensions of thought and their association with emotional experiences.

Main Methods:

• Utilized multi-dimensional experience sampling via smartphones to collect real-time data.
• Recruited 190 undergraduate students (ages 18-36, 159 female).
• Employed Principal Component Analysis and Linear Mixed Models to analyze thought patterns and affective states (valence, arousal, stress).

Main Results:

• Identified four key thought dimensions: future-self orientation, intrusive distraction, sensory engagement, and task-focus.
• Discovered that alexithymia influences these thought-emotion relationships.
• High alexithymia was linked to reduced future-self orientation and increased sensory engagement variability; difficulty identifying feelings specifically decreased future-self orientation during sadness; externally oriented thinking reduced sensitivity to affective context.

Conclusions:

• Mapped affective experiences onto specific thought dimensions, revealing cognitive pathways influencing emotional well-being.
• Established a scalable framework for understanding variations in human affective experiences.
• Highlighted the role of alexithymia in modulating the dynamic interplay between cognition and emotion.
