An examination of the relative contribution of saturation and selective attention to memory deficits in patients with recent-onset schizophrenia and their unaffected parents.
Bibliographic record
Abstract
Cognitive dysfunctions in patients suffering from schizophrenia (SZ) are also found in their unaffected parents though to a lesser degree. According to several researchers, short-term memory (STM) deficits are a potential marker of vulnerability to SZ. However, the cognitive processes underlying the observed STM deficits remain underspecified in SZ (Lee & Park, 2005). In the present study, our goal was to pinpoint those processes at play in the manifestation of STM deficits by using the paradigm of the sandwich effect (e.g., Hitch, 1975) to manipulate information load (5 vs. 7 to-be-remembered items) and distraction (control vs. sandwich) in the verbal domain. Our study comprises four groups: patients with SZ (n = 25), their unaffected parents (n = 25), and their respective healthy controls. The pattern of results indicates a generalized dysfunction of STM in patients with SZ characterized by saturation and an increased susceptibility to distraction. The impact of saturation and distraction was also observed in unaffected parents of patients with SZ to a lesser degree. The methodological strategy adopted here allowed us to show that the dysfunction of STM is genuine, can be aggravated by deficits in selective attention, and is a good candidate for further research on genetic epidemiology.

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.
