Effect of manipulation and irrelevant noise on working memory capacity of patients with Alzheimer's dementia.
Bibliographic record
Abstract
The effect of manipulation and distracting noise on immediate serial recall was measured in patients with dementia of the Alzheimer type (DAT), normal elderly individuals and young subjects.Experiment 1 compared serial word recall to word recall in alphabetical order.Alphabetical recall requires the active manipulation of the contents of working memory.Findings indicated that patients were severely impaired in the alphabetical recall task whereas performance of normal elderly subjects was comparable to young subjects.Experiment 2 investigated the effect of different irrelevant auditory backgrounds on immediate digit recall.In this task, both normal elderly subjects and DAT patients performed similarly to the group of young subjects, indicating comparable efficacy to resist auditory distraction.Heterogeneity of performance was assessed in the DAT patients, revealing that the alphabetical tasks yielded particularly heterogeneous performance levels.Finally, the absence of any systematic relationship between the two tasks suggests that they reflect different aspects of working memory.

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.
