Effect of Comorbid Post-Traumatic Stress Disorder and Panic Disorder on Defensive Responding
Bibliographic record
Abstract
Abstract. Although panic disorder (PD) and post-traumatic stress disorder (PTSD) are characterized by heightened sensitivity to threat, no study to date has examined the effect of comorbid PD and PTSD on defensive responding. The present study probed startle eyeblink response to an acoustic probe in three groups of participants recruited from the community: (1) healthy individuals (n = 63), (2) individuals with PD without PTSD (n = 62), and (3) individuals with comorbid PD and PTSD (n = 24). Results indicated that PD individuals without PTSD exhibited greater sensitivity to threat relative to controls, and comorbid individuals displayed attenuated sensitivity to threat relative to PD individuals without PTSD (both ps < .05). The results are discussed in the context of the anxiety disorder spectrum, which postulates that anxiety disorders exist on a continuum spanning from specific/simple fear to broad distress, with defensive responding decreasing as distress increases.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
