ASSOCIATIONS OF ALEXITHYMIA WITH ANTERIOR AND POSTERIOR ACTIVATION ASYMMETRIES DURING EVOKED EMOTIONS: EEG EVIDENCE OF RIGHT HEMISPHERE "ELECTROCORTICAL EFFORT"
Bibliographic record
Abstract
The objective of the study was to examine alexithymia influence on regional cortical activity in nonpatient individuals during evoked emotions. The 62-channels EEG was recorded in non-alexithymic (n = 27) and alexithymic (n = 17) participants viewing emotional film clips. Effects of alexithymia were found in the upper theta, low and upper alpha frequency bands; in all the bands the alexithymics exhibited greater reactivity of the right hemisphere, suggesting enhanced avoidance motivational tendencies, negative affect, and autonomic arousal. Such a right-hemispheric "electrocortical effort" in alexithymia could reflect difficulties in symbolization of emotion resulting from impaired right-hemispheric analogical and global nonverbal emotional representation.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
