The role of food-cue exposure and negative affect in the experience of thought-shape fusion.
Thought-shape fusion (TSF) is a cognitive distortion that can be induced by imagining eating high-caloric foods, and involves increased guilt, feelings of fatness, and perceptions of weight gain and moral wrong-doing. Two studies were conducted to further elucidate this phenomenon. Study 1 investigated whether merely being exposed to fattening foods (without being asked to think about these foods) could induce a TSF-like experience. Study 2 investigated the relationship between negative affect and TSF-like experiences. The results suggested that TSF is specific to thinking about eating fattening foods, as mere exposure to high-caloric foods did not increase state TSF scores in healthy females relative to a neutral control condition. Furthermore, susceptibility to TSF is associated with negative affect. Healthy females with low levels of negative affect appear to be protected against TSF, medium negative affect is associated with susceptibility to TSF inductions, while those with high levels of negative affect appear to be particularly vulnerable to TSF-like experiences (even after imagining a neutral situation). Overall, the studies suggest that negative affect is associated with a TSF-like experience, and that TSF is a phenomenon that is experienced (to at least some extent) by females in the general population.
