Structural Modeling of Temporal Dominance Responses Using Covariances of Contemporary Changes in Subjective Qualities

抄録

The establishment of methods for recording and analyzing the dynamic changes in the human affective responses is important for understanding and utilizing affective dynamics. This study analyzes the structure of sensory and affective responses recorded through the temporal dominance (TD) method, which is an effective dynamic sensory appraisal approach. Temporal evolution is modeled by state-space local-level equations, and the structure of the responses is estimated based on the covariance matrix of the disturbances of the state variables. This approach is applied to the TD responses for strawberries recorded in a previous study, and its validity is examined.
