Overview
Successfully perceiving the flow of interoceptive cues and integrating them with exteroceptive information are fundamental aspects of countering the body's inherent instability and guaranteeing homeostatic regulation. This process deeply affects cognitive/emotional functioning and general health. Recently, it has been suggested that an important signature underpinning obesity might be an interoceptive dysfunction in perceiving internal body signals and/or integrating them with information from the external environment. There is evidence that interoceptive deficits correlate with Body Mass Index (BMI), but it is still largely unclear how different measures and facets of interoception are related to high BMI and eating behaviour. Within this framework, it is mandatory to understand the role of interoception in obesity at perceptual, cognitive, and emotional levels. One open issue regards the relationships between interoceptive signals and the reactivity to external food cues.
Interventions
- Behavioral The crossmodal dual-task
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 togethe
Primary outcome measures
- Visual detection velocity [Time frame: At the moment of the experiment]
- Interoceptive judgement [Time frame: At the moment of the experiment]
Secondary outcome measures (1)
- Visual detection accuracy [Time frame: At the moment of the experiment]
