The Sense of Small and Inhibition in Obesity

Investigating the Relationship Between the Sense of Smell and Cognitive Inhibition in Obesity: a Behavioural Experiment.

The aim of this research is to verify whether inhibitory control ability is different between a group of individuals with obesity and a group of individuals with normal weight in the presence of olfactory stimuli, different for valence, edibility (food versus no-food), and caloric density (high-calorie vs low-calorie content) of foods associated with odours.

Inclusion criteria:

• Right-handed
• diagnosis of obesity (i.e., the level of body mass index (BMI) higher or equal to 30).

Exclusion criteria:

• Concurrent neurological, neurodevelopmental (e.g., autism), motor, somatosensory and/or psychiatric disorders.
