Summary

Overweight and obese individuals will be randomly assigned to a food-specific or generic inhibitory control training. Food intake, weight, and neural indices of inhibitory control will be assessed prior, immediately after the 4-week intervention, and 12-weeks after intervention completion to assess the effectiveness of a mobile inhibitory control training intervention over time for health outcomes.

Detailed description

All participants will report to the lab for a baseline session, where their weight, average food intake for three days (using the Automated Self-Administer 24-hour Dietary Recall \[ASA24\] system), neural indices of inhibitory control (as assessed by the N2 event-related potential component during a food and genetic go/no-go task), appetitive drive toward food (as measured by the Power of Food Scale) and basic demographic information will be assessed. Based off their gender and baseline levels of inhibitory control (indicated by the N2), participants will be assigned to a four week food-specific inhibitory control training or a generic inhibitory control training. Trainings are administered on a mobile device via an app and participants select four our of five business days to complete the trainings on. Immediately after the four weeks, participants will come in for a follow-up session where their weight, food intake, N2, and appetitive drive to food will be assessed again. Finally, participants will have a 12-week waiting period where they do not complete the trainings. After the 12 weeks, they will come in for a final lab visit where their weight, food intake, N2, and appetitive drive to food will be assessed one last time.

Conditions

• Overweight and Obesity

Interventions

Type	Name	Description
BEHAVIORAL	Inhibitory Control Training	Computerized go/no-go task where individuals make responses to certain items (go trials) and withhold responses from certain items (no-go trials, in this case, trials surrounded by a black box). Intervention is designed to target and improve inhibitory control cognitive mechanisms in general (generic arm) or towards high-calorie foods specifically (food arm).
