Vector Auto-Regression Model of Temporal Perceptual and Affective Responses Towards Food

摘要

Although human perceptual and affective responses triggered by the exposure to sensory experiences are dynamic, their temporal evolution has not been intensively investigated. In this study, we aimed to construct a mathematical model of such dynamics. The perceptual and affective responses while eating strawberries were measured using the temporal dominance of sensations method. We modeled them with a vector auto-regression (VAR) model based on Granger causality between perceptual and affective responses.
