The API group aims to explore the interplay between mind and body, focusing on interoception processes and bodily representations in the social and affective domains. Through psychophysiological measurements (e.g., skin conductance, heart rate, body temperature) and behavioral techniques, we investigate how emotions influence physiological responses and bodily sensations.

Affect in the dark: Navigating the complex landscape of social cognition in blindness
Domenici, Collignon, LettieriProgress in Brain Research, 2025. DOI: 10.1016/bs.pbr.2025.02.002ABSTRACT: Research on the consequence of blindness has primarily focused on how visual experience influences basic sensory abilities, mainly overlooking the intricate world of social cognition. However, social cognition abilities are crucial as they enable individuals to navigate complex interactions, understand others’ perspectives, regulate emotions, and establish meaningful connections, all essential for successful adaptation and integration into society. Emotional and social signals are frequently conveyed through nonverbal visual cues, and understanding the foundational role vision plays in shaping everyday affective experiences is fundamental. Here, we aim to summarize existing research on social cognition in individuals with blindness. By doing so, we strive to offer a comprehensive overview of social processing in sensory deprivation while pinpointing areas that are still largely unexplored. By identifying gaps in current knowledge, this review paves the way for future investigations to reveal how visual experience shapes the development of emotional and social cognition in the mind and the brain.
Visual experience shapes bodily representation of emotion
Lettieri, Calce, Giraudet, CollignonEMOTION, 2024. DOI: 10.1037/emo0001440ABSTRACT: Philosophers and experimentalists have long debated whether bodily representation of emotion is grounded in our sensory experience. Indeed, we are used to observe emotional reactions expressed through the bodies of others, yet it is still unknown whether this observation influences how we experience affective states in our own bodies. To delve into this question, we developed a naturalistic haptic task and asked a group of early (n=20) and late (n=20) blind, as well as sighted individuals (n=20) to indicate where in the body they perceive changes associated with affective states. Our results show that visual experience shapes bodily representation of emotion. Blind and sighted individuals attribute different importance to body regions in relation to specific emotional states, as sighted people focus more on visceral sensations, while blind report as more relevant the mouth and the hand areas. We also observe differences in the coherence of bodily maps of specific emotions, such as aggressiveness, for which early and late blind are homogenous in reporting the mouth, while sighted subjects demonstrate a scattered pattern of activation across the body. Finally, our findings show that blind people rely on a different organization of affect, as only sighted categorize bodily maps of emotion through the valence and arousal dimensions. In summary, we demonstrate that sensory experience impacts the bodily representation of affect by modulating the relevance that different body parts have in emotional reactions, by modifying the weights attributed to interoceptive and exteroceptive signals, and by changing how emotions are conceptualized in the body.
Dissecting abstract, modality-specific and experience-dependent coding of affect in the human brain
Lettieri, Handjaras, Cappello, Setti, Bottari, Bruno, Diano, Leo, Tinti, Garbarini, Pietrini, Ricciardi, CecchettiScience Advances, 2024. DOI: 10.1126/sciadv.adk6840ABSTRACT: Emotion and perception are tightly intertwined, as affective experiences often arise from the appraisal of sensory information. Nonetheless, whether the brain encodes emotional instances using a sensory-specific code or in a more abstract manner is unclear. Here, we answer this question by measuring the association between emotion ratings collected during a unisensory or multisensory presentation of a full-length movie and brain activity recorded in typically developed, congenitally blind and congenitally deaf participants. Emotional instances are encoded in a vast network encompassing sensory, prefrontal, and temporal cortices. Within this network, the ventromedial prefrontal cortex stores a categorical representation of emotion independent of modality and previous sensory experience, and the posterior superior temporal cortex maps the valence dimension using an abstract code. Sensory experience more than modality affects how the brain organizes emotional information outside supramodal regions, suggesting the existence of a scaffold for the representation of emotional states where sensory inputs during development shape its functioning.

HABEMO: an innovative haptic tool for investigating the bodily representation of mental states in individuals with visual impairments
Our novel haptic paradigm allows the mapping of emotions in the body in an intuitive way, offering a more inclusive and versatile method for exploring how people connect their emotions to their physical experiences. The haptic version of our task holds particular promise for investigating how individuals with limited or no visual capability maintain representations of emotional and cognitive states within their bodies. In addition to its profound implications for understanding emotions, this innovative tool holds promise for exploring a wide variety of research questions beyond the realm of affective states, thereby broadening its utility as a versatile instrument for investigating various aspects of human perception, cognition, and embodiment particularly within the context of visual impairment.
