Databases of spontaneous multimodal expressions of affective states occurring during a task are few. This paper presents a protocol for eliciting stress in a public speaking task. Behaviors of 19 participants were recorded via a multimodal setup including speech, video of the facial expressions and body movements, balance via a force plate, and(More)
OBJECTIVES Alexithymia is a personality trait characterized by difficulties in identifying, describing and communicating one's own emotions. Recent studies have associated specific effects of this trait and its subfactors with hypothalamo-pituitary-adrenal (HPA) axis markers during stress. The aim of this study was to analyze the association between(More)
Postural control is a dynamical process that has been extensively studied in motor control research. Recent experimental work shows a direct impact of affects on human balance. However, few studies on the automatic recognition of affects in full body expressions consider balance variables such as center of gravity displacements. Force plates enable the(More)
