Right-handed women diagnosed with obesity are consecutively recruited during their rehabilitative treatment at the Istituto Auxologico Italiano, IRCCS, San Giuseppe Hospital (Italy). Concurrent neurological, neurodevelopmental (e.g., autism), motor, somatosensory and/or psychiatric disorders are exclusion criteria.

Age-matched, right-handed, healthy women (i.e., with no history of eating disorders) are recruited outside the hospital through personal contacts of the researchers and word-of-mouth.

Two main sensory tasks performed together:

1. the visual task, in which participants are requested to monitor visual stimuli presented on a computer screen and to detect the "deviant" target" as soon as possible. The target changes across blocks: in half of the trials, participants will have to respond to food stimuli presented together with irrelevant non-food stimuli (food target condition); in the other half conditions, participants will have to respond to non-food stimuli presented together with irrelevant food stimuli (non-food target condition). For each participant, we will collect the Reaction Time in milliseconds only for the valid responses, and the level of Accuracy in percentage.

2) The interoceptive task, in which participants are requested to monitor their heartbeat presented through headphones and registered through pulse oximetry. Participants will judge the level of asynchrony between their heartbeat and the auditory cue.

Reaction Time in milliseconds only for the valid responses in the visual task

Individual's judgement from 0 (no synchronicity) to 100 (maximum synchronicity) between between the auditory stimulus and own heartbeat in the heartbeat detection task

Percentage of the correct answers in the "No-Go" trials in the visual task.
