Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main study parameters/endpoints are (1) the difference in brain activation between an anticipatory reward and a consummatory reward and (2) the difference in brain activation between a consummatory reward labeled as light versus labeled as regular. | — |
Secondary
| Measure | Time frame |
|---|---|
| The 1st secondary study parameter/endpoint is the correlation between brain activation in response to exposure to an anticipatory or a consummatory reward and reaction times and errors (push/pull measure). In addition, two groups will be made based on the product choice outcome and anticipatory reward responses and consummatory reward responses are compared between those groups (i.e. there is looked at the group*reward response interaction). The 2nd secondary study parameter/endpoint is the correlation between brain activation in response to exposure to an anticipatory or a consummatory reward and subject characteristics like reward sensitivity, delayed discounting, impulsivity, health attitude, stress, executive functioning and food neophobia. | — |
