Abstract
Research increasingly shows links between trauma exposure, posttraumatic stress symptoms, and cognitive functioning. We know relatively little about the long-term cognitive correlates of exposure to trauma, especially in civilian populations exposed to war and political violence. OBJECTIVE: Our goal was to examined short-term memory (STM) and executive function 20 years after the 1994 genocide of the Tutsis in Rwanda. We hypothesized that performance on these tasks would be negatively related to trauma exposure and to posttraumatic stress disorder (PTSD) symptoms. METHOD: In two studies, 470 Rwandan participants answered questionnaires measuring the severity of experiences that occurred during the 1994 genocide and current levels of PTSD symptoms. In both studies, we tested STM using a forward digit span task. In the second study, we also measured executive function using a semantic fluency task. RESULTS: There were modest but significant negative links between the severity of experiences during the genocide and STM function more than 20 years after. Current levels of PTSD symptoms were also related to STM and executive function. CONCLUSIONS: This study reveals the important link between exposure to highly emotional events and cognitive function and highlights the need to attend not only to the mental health but also to the cognitive health of populations exposed to political violence.

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 it
