Executive Functions in Relation to Impulsivity Following Traumatic Brain Injury
Bibliographic record
Abstract
Impulsivity is a common and debilitating sequela following traumatic brain injury (TBI) and should be assessed during the rehabilitation process. It is now accepted that impulsivity is a multidimensional construct and such a distinction may help in understanding the mechanisms underlying impulsivity and facilitate assessment. The goal of this study is to examine the link between impulsive behaviors and their underlying mechanisms in a TBI sample. Twenty-five TBI patients and twenty-four matched controls were administered performance tasks measuring prepotent response inhibition, resistance to proactive interference, and decision-making. Group comparisons show weaker performance on measures of inhibition and decision-making by the TBI participants. Finally, performance on the Modified Six Elements Task was associated with impulsive behaviors in everyday life as observed by treating clinicians. This study sheds light on the associations between executive functions and impulsivity in an acute rehabilitation setting.

How this classification was reachedexpand
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.
