- Lead Sponsor
- University Hospital, Grenoble
- Brief Summary
This fMRI study evaluated the cognitive mechanisms and the cerebral substrate of decision making when evaluating the healthiness of food products with nutritional information displayed either with a Traffic Light system, a colored nutritional label, and a Guideline Daily Amount system, a numeric label.
- Detailed Description
The investigators postulated that Traffic Light label would recruit emotion processes and activation of subjacent cerebral networks.
On the contrary, the nutritional information presented in a Guideline Daily Amount label, would recruit, due to its numeric format and higher complexity, supplementary cognitive processes and activation of related brain regions.
