Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Measured at a single time point: 1. Implicit motivation assessed by reaction time (ms) using the Manikin task: The reaction time (RT) will be measured from the onset of a stimulus until the first key press. Trials with errors as well as RTs below 200 ms and above 1500 ms will be excluded from the RT analysis. 2. Food choice assessed using the food choice task: Two hypothetical food selection tasks will be completed. The selection will comprise eight items, including the four chocolate bars and four healthier snacks. Participants will be shown the selection and asked to select the food product they would most like to eat now | — |
Secondary
| Measure | Time frame |
|---|---|
| Measured at a single time point: 1. Implicit motivation measured by counting errors and reaction time (ms) in the Go, No-go task : The number of commission errors (falsely pressing the space bar in no-go trials), omission errors (falsely not pressing the space bar in go trials) and mean RTs for correct go responses will be calculated for the chocolate bars and the stationery items in each condition. Implicit motivation will be assessed by an approach bias towards the stimuli. A higher number of commission errors, a lower number of omission errors and a lower (therefore faster) RT indicate an approach bias, which in turn is indicative of a higher implicit motivation towards the stimuli. 2. Explicit liking and wanting will be assessed using a 100mm visual analogue scale to two questions Liking: “How much do you like this chocolate bar generally?” Wanting: “How much do you want one of these chocolate bars right now?” For control stimuli the questions will read: “How much do you like this product generally?” and “How much do you want this product right now?”. A mean liking and wanting score will be calculated for the chocolate bars and the control stimuli | — |
