Abstract

In the current research we examined how resolve-based reminders affect long-term choice adherence as a function of its distinct features, specifically the number of self justifications embedded in the reminders. Additionally, we sought to assess the unique role of individual differences on choice adherence, as manifested in working memory capacity and decision making style. For this purpose we developed an experimental weight loss program using reminders while varying the number of self-generated textual justifications. Volunteer participants were sixty over-eaters who resolved to lose weight. All participants used a reminder of their resolve to modify their eating habits. In the three experimental conditions, this reminder included either a single or multiple self-generated textual justifications, or did not include a textual reminder. Weight loss was assessed after one month of treatment and in an additional follow-up after two months. An ANOVA analysis revealed that weight loss was higher for reminders with multiple compared to single self justifications. Also, an interaction was found between working memory capacity and decision making style on weight loss that partially supports the role of working memory in choice adherence. Overall the results extend the knowledge on behavioral modification utilizing the justification aspects of reminders, while emphasizing the need for further examination of reminders' features and of the interacting role of working memory and decision making in choice adherence in real-life settings.
