In the current research we conducted two experiments, designed to investigate different theoretical assumptions of the self control strength model (Baumeister et al.,2006; Muraven & Baumeister, 2000; Muraven, Tice, & Baumeister, 1998). The first experiment in this research utilized a smoking cessation program, in order to delve into the mechanisms implicated in one of the most popular self-control exercise manipulations, the upright posture. Results indicated that a reminder regime works as well as the self-control exercise manipulation. We hypothesize that these results implicate reminders as confound in the self-control manipulation. Additionally, we found an effect for motivation, such that self-reported motivation for entering the program had a significant strong negative correlation (r= -0.648, p<0.001) with the ratio of cigarettes still consumed at the end of the program. The second experiment was aimed at investigating the concept of ego-depletion in a decision making task; the Haifa Gambling Task (Agay, Yechiam, Carmel & Levkovitz, 2010). Following Muraven et al., (1998) and Baumeister et al. (1998), we depleted participants’ ego by instructing them to suppress or enhance negative affect while watching an upsetting movie. The results offer partial support for the ego-depletion hypothesis, as well as raise interesting questions regarding the differences between emotional suppression and emotional enhancement.
