Self-regulation of intention formation is pivotal for achieving behavior change. Fantasy realization theory (Oettingen, 2000) assumes that mentally contrasting a desired positive future with present negative reality turns high expectations of success into strong intentions to realize the desired future, while indulging in the positive future fails to do so. The present study tests the theory s process assumption that mental contrasting is a cognitively demanding, purposeful problem-solving strategy involving working and episodic memory, whereas indulging is a mindless daydreaming strategy involving the free flow of thought, by investigating the neural correlates of the two strategies via continuous magnetoencephalographic (MEG) activity. We observed greater activity during mental contrasting (but not indulging) compared to resting in prefrontal, frontal, parietal, and temporal areas, indicating that mental contrasting involves strong intention formation, working memory, and episodic memory. In addition, heightened activity of occipital areas was observed during mental contrasting compared to resting and indulging, suggesting that mental contrasting, more than indulging and resting, entails purposefully creating mental images. Taken together, these findings indicate that mental contrasting is indeed a purposeful problem-solving strategy based on past performance history, whereas indulging is a purposeless daydreaming strategy that is oblivious to past experiences.

Forming an implementation intention or "if-then plan" promotes the attainment of different types of goals (Gollwitzer, 1999; Gollwitzer & Sheeran, 2006). So far, research on implementation intentions has focused on on the initiation of goal striving, whereas the issue of shielding of ongoing goal striving has been largely neglected. In two field experiments concerned with dieting (Study 1) and athletic goals (Study 2), goal shielding was supported by implementation intentions geared at controlling potentially interfering inner states (i.e., cravings for junk food in Study 1, and disruptive thoughts, feelings, and physiological states in Study 2). In both experiments, forming if-then plans enhanced the rate of goal attainment. Thus, implementation intention formation can be used to promote the realization of desired outcomes not only by facilitating getting started with goal striving but also by preventing goal striving from straying off course.

Forming implementation intentions ( If I encounter cue X, then I will perform behavior Y! ) is postulated to trigger action initiation without further conscious intent once the specified cue is encountered (Gollwitzer, 1999). In two experiments using an injustice paradigm or a categorization task, critical situations (specified in the if-component) were subliminally presented and it was tested whether these situations influenced the preparation (Study 1) and initiation (Study 2) of the planned goal-directed behavior (specified in the then-component). After the subliminal presentation of the critical situations, implementation intention participants showed stronger action preparation and a faster action initiation, as compared to control participants (Study 1) who had not formed any goal intention at all, and compared to participants (Studies 1 and 2) who had only formed goal intentions. These findings suggest that forming implementation intentions leads to automatic action initiation without further conscious intent.
