Background: As Taiwan enters a super-aged society, the prevalence of dementia continues to rise, highlighting the need for scalable, noninvasive approaches to identify behavioral alterations associated with cognitive decline. AI-based analysis of spontaneous affective facial responses has emerged as a potential digital phenotyping tool, but its #feasibility for assessing cognitive performance remains underexplored. Objective: This study aimed to examine the #feasibility of using AI-derived spontaneous affective facial response metrics, including affective expression congruency and onset latency, to characterize differences across cognitive performance levels in older adults with healthy cognition (HC), mild cognitive impairment (MCI), or dementia. Methods: A total of 60 participants (HC, MCI, and dementia; 20 per group) were presented with positive and negative emotion-eliciting videos and completed Mini-Mental State Examination (MMSE) recall and calculation tasks. Facial expressions were video-recorded and analyzed using a convolutional neural network–based AI system. AI-derived metrics included affective expression congruency, categorized as congruent, neutral, or incongruent according to the detected facial response, and affective expression onset latency, defined as the time from stimulus presentation to the emergence of a nonneutral facial expression detected by the AI model. Group differences were analyzed using 1-way ANOVA, Pearson chi-square or Fisher-Freeman-Halton exact tests, Bonferroni-adjusted pairwise post hoc comparisons, analysis of covariance adjusting for age and education, and exploratory receiver operating characteristic analyses. Results: Affectively congruent responses were generally less frequent among participants with lower cognitive performance. During the 14-second positive stimulus, congruent positive expressions were observed in 65% (13/20) of HC participants, 20% (4/20) of MCI participants, and 0% (0/20) of participants with dementia. During the 48-second negative stimulus, congruent negative expressions were observed in 60% (12/20) of HC participants compared with 5% (1/20) of both MCI and dementia participants. Onset latency differed significantly across groups for the 14-second positive stimulus (F2,57=19.63; P

Why do we see red, feel blue, or turn green with envy? Join our one-day online seminar with Dr Domicele Jonauskaite (Institute of Psychology, University of Lausanne) to explore the fascinating intersection of colour perception, emotion, language, and culture. Designed for PhD students, post-docs, professors, and research professionals, this workshop will synthesize evidence from a recent systematic review and large-scale research spanning 73 countries and 46 languages, examining which colour–emotion associations may be universal and which are shaped by cultural, geographic, and linguistic context. Participants will gain insight into cross-cultural research design, reproducible and quantitative methods, and mechanistic evidence from colour-blind and blind populations, with opportunities to discuss collaborative projects, preregistration, and publication strategies. The seminar will be held via Zoom, with recordings, slides, materials, and a monitored Q&A forum available for 30 days afterward, and participants will receive an official Instats certificate of completion. #AffectiveScience #CognitivePsychology #CulturalStudies #Psychology #QuantitativeMethods #Statistics #Anthropology #Linguistics #CognitiveScience #Research #ResearchTraining #Instats

Why do we “see red,” “feel blue,” or “turn green with envy”? Join Dr Domicele Jonauskaite (Institute of Psychology, University of Lausanne) for a one-day online workshop exploring the fascinating intersection of colour, emotion, perception, language, and culture. Designed for PhD students, post-docs, professors, and professional researchers, this seminar synthesizes evidence from a recent systematic review and large-scale empirical work across 73 countries and 46 languages to examine which colour–emotion associations may be universal and which are shaped by cultural, linguistic, and geographic factors. Participants will gain insight into rigorous cross-cultural research methods, mechanistic evidence from colour-blind and blind populations, and practical considerations for studying affective phenomena across diverse populations. The seminar includes live Zoom access, 30-day access to recordings and materials, an online Q&A forum, and an official Instats certificate of completion, with ECTS Equivalent points available where applicable. #AffectiveScience #CognitivePsychology #CulturalStudies #Psychology #QuantitativeMethods #Statistics #Anthropology #Linguistics #CognitiveScience #Research #ResearchTraining #Instats

Why do we see red, feel blue, or turn green with envy? Join Dr Domicele Jonauskaite (University of Lausanne) for a one-day, research-focused workshop that synthesizes a systematic review and a large-scale empirical study spanning 73 countries to unpack universalities and cultural specificities in colour–emotion correspondences. Designed for PhD students, post‑docs, and research professionals, the seminar covers empirical evidence and statistical frameworks, mechanisms (including data from colour‑blind and blind participants), cross‑cultural patterns explained by geography and language, and best practices for reproducible, open, quantitative cross‑cultural affective research (stimulus selection, translation, sampling, preregistration, and publication strategies). All sessions are livestreamed via Zoom with recordings, slides, data, and a monitored Q&A forum available for 30 days after the seminar; participants receive an Instats certificate of completion (ECTS‑equivalent points shown where applicable).
