The problem of the measurement of emotion is a widely debated one. In this article we propose an instrument, the Homogenization of Classification Functions Measure (HOCFUN), designed for assessing the influence of emotional arousal on a rating task consisting of the evaluation of a sequence of images. The instrument defines an indicator (κ) that measures the degree of homogenization of the ratings given over 2 rating scales (pleasant–unpleasant and relevant– irrelevant). Such a degree of homogenization is interpreted as the effect of emotional arousal on thinking and therefore lends itself to be used as a marker of emotional arousal. A preliminary study of validation was implemented. The association of the κ indicator with 3 additional indicators was analyzed. Consistently with the hypotheses, the κ indicator proved to be associated, even if weakly and nonlinearly, with a marker of the homogenization of classification functions derived from a separate rating task and with 2 indirect indicators of emotional activation: the speed of performance on the HOCFUN task and an indicator of mood intensity. Taken as a whole, such results provide initial evidence supporting the HOCFUN construct validity.

Abstract
The problem of the measurement of emotion is a widely debated one. In this article we propose an instrument, the Homogenization of Classification Functions Measure (HOCFUN), designed for assessing the influence of emotional arousal on a rating task consisting of the evaluation of a sequence of images. The instrument defines an indicator (κ) that measures the degree of homogenization of the ratings given over 2 rating scales (pleasant–unpleasant and relevant– irrelevant). Such a degree of homogenization is interpreted as the effect of emotional arousal on thinking and therefore lends itself to be used as a marker of emotional arousal. A preliminary study of validation was implemented. The association of the κ indicator with 3 additional indicators was analyzed. Consistently with the hypotheses, the κ indicator proved to be associated, even if weakly and nonlinearly, with a marker of the homogenization of classification functions derived from a separate rating task and with 2 indirect indicators of emotional activation: the speed of performance on the HOCFUN task and an indicator of mood intensity. Taken as a whole, such results provide initial evidence supporting the HOCFUN construct validity.File | Dimensione | Formato | |
