2025 Tell-Tale Eye

The dataset comprises eye-tracking and galvanic skin response (GSR) recordings from 37 older adults in Taiwan, stratified by Clinical Dementia Rating (CDR 0, 0.5, 1), during reminiscence therapy using self-selected autobiographical photos. It captures pupil–GSR synchrony patterns in response to early-life (≥30 years) and recent (<5 years) family-centered images, providing physiological indicators of residual ocular and emotional–attentional function.
