Investigating interruptions in the context of computerised cognitive testing for older adults
Bibliographic record
Abstract
Interruptions in the home pose a threat to the validity of self-administered computerised cognitive testing. We report the findings of a laboratory experiment investigating the effects of increased interruption workload demand on older adults' computerised cognitive test performance. Related work has reported interruptions having a range of inhibitory and facilitatory effects on primary task performance. Cognitive ageing literature suggests that increased interruption workload demand should have greater detrimental effects on older adults' performance, when compared to younger adults. With 36 participants from 3 age groups (20-54, 55-69, 70+), we found divergent effects of increased interruption demand on two primary tasks. Results suggest that older and younger adults experience interruptions differently, but at no age is test performance compromised by demanding interruptions. This finding is reassuring with respect to the success of a self-administered computerised cognitive assessment test, and is likely to be useful for other applications used by older adults.

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.
