Primary

MeasureTime frame
Proportion of participants taking any of either snack food, measured as any difference in bowl weight from before to after the participant is exposed to the snacks.

Secondary

MeasureTime frame
1. Mean amount of each snack food consumed is measured as the difference in bowl weight from before to after the participant is exposed to the snacks 2. Executive function, measured using the Stroop task (Stroop, 1935) before exposure to the snack food 3. Ratings of perceived effort to obtain the snacks and salience of the snacks, collected using a questionnaire following exposure to the snack food 4. The proximity effect is measured by the difference in intake of the snacks at each given distance after the relaxation break. This difference in intake is compared before and after excluding participants who move the bowl.
