How emotions are perceived in the absence of vision
How emotions are perceived in the absence of vision
Facial expressions reveal people's emotional states. From happiness and surprise to fear and disgust, interpretation relies on detecting salient information. This is a task chiefly accomplished through vision. Affective signals are conveyed through nonverbal communication and can be experienced and perceived exclusively through sight. In this context, the EU-funded LEAS project investigates how emotions are perceived in the absence of vision. To find the answers, LEAS studies how much the representation of emotional bodily sensations depends on sight and whether the stream of affect is differently encoded in the brain of sighted and blind individuals.

Using semi-structured interviews and computational linguistics, we explore whether early, late blind and sighted share the same semantic representation of positive and negative feelings

Using a naturalistic haptic task, we investigate whether visually impaired and sighted subjects retain different somatotopic maps of bodily sensations of emotions

Using neuroimaging and naturalistic stimulation, we assess whether different brain networks are involved in the coding of affective experiences across visually impaired and sighted individuals
