요약Why are some people successful at regulating their urges and cravings whereas others are more likely to give in to them? People use a variety of different self-regulation tools to achieve success. How these strategies change the way our brain processes information about food is not well understood. A goal of this research is to understand how different self-regulation strategies change the brain's response to food, which may help us understand why some people are good at controlling their eating behavior and others struggle with it. First, we generate a high quality image set suitable for use in a multivariate fMRI context (Chapter 2). Then, we investigate how shifting attention to different food attributes (Chapter 3) and how taking the perspective of a successful and unsuccessful self-regulator (Chapter 4) changes how the brain encodes important features of food like taste and health, and what areas support these changes. In addition to recording brain responses, we measure how often people make unhealthy or healthy food choices over the course of a week by texting them to complete short surveys on their smartphones. We find that changing one's attentional focus changes the dominant features that are represented in the brain's reward system. Further, we find that similarity towards a health-focused mindset predicts healthier food decisions in day-to-day-life. Mental simulation is found to change the way food information is organized, both cognitively and neurally. Additionally, we find that regions related to social cognition support these differences in representation. In so doing, this work provides some evidence of how the brain encodes the tastiness and healthiness of foods, and the regions supporting this representation, to help clarify good strategies for dietary self-control and ultimately to help populations that struggle with in this domain.
