Perception and Emotional Judgments of Music in Dementia of the Alzheimer Type: A Short Case Study
Bibliographic record
Abstract
dementia of the alzheimer type (ad) can affect emotional judgments of facial expression and prosody. Spared emotional judgments of music have been observed in early AD (Gagnon, Peretz, & Fülöp, 2009). The AD case study of Cuddy and Duffin (2005) showed relatively spared perception and memory for music. Through the single case study of MD, we again address the question of whether early AD might leave these abilities intact. The first experiment examined her musical emotional judgments in relation to mode and tempo. Overall results replicated the finding of a preserved response to changes in these structural properties. In a second experiment, we examined MD's recognition of musical and facial emotional expressions. She demonstrated a deficit only for the recognition of the facial expression of anger. Her performance adds to other empirical demonstrations that in early AD music perception and memory, as well as musical emotional judgments, may be relatively preserved.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
