Gestural and Postural Reactions to Stressful Event: Design of a Haptic Stressful Stimulus

Previous studies about kinesthetic expressions of emotions are mainly based on acted expressions of affective states, which might be quite different from spontaneous expressions. In a previous study, we proposed a task to collect haptic expressions of a spontaneous stress. In this paper, we explore the effectiveness of this task to induce a spontaneous stress in two ways: a subjective feedback, and a more objective approach-avoidance behavior.
