Understanding dieting: A social cognitive analysis of hedonic processes in self-regulation

The present paper introduces a novel approach to understanding failures of self-regulation in chronic dieters. Traditional approaches to this problem have focused on consciously controlled processes of eating regulation, such as the realisation that one has overeaten, or the experience of food cravings. We argue, however, that dieters' problem might rather lie in their sensitivity to the hedonic aspects of food and the resulting inhibition of their dieting goal. We present a goal-conflict model that integrates recent findings on hedonic sensitivity in eating regulation with social cognition research on nonconscious goal pursuit. We show that the perception of attractive food triggers hedonic thoughts about food in chronic dieters and leads to the inhibition of their dieting goal. These processes make subsequent overeating more likely, while bypassing dieters' conscious awareness. We discuss how our model can accommodate earlier research findings in this area, and we consider its implications for dieting behaviour and for our attempts to resist temptations more generally.     

A new perspective on human reward research: How consciously and unconsciously perceived reward information influences performance

The question of how human performance can be improved through rewards is a recurrent topic of interest in psychology and neuroscience. Traditional, cognitive approaches to this topic have focused solely on consciously communicated rewards. Recently, a largely neuroscience-inspired perspective has emerged to examine the potential role of conscious awareness of reward information in effective reward pursuit. The present article reviews research employing a newly developed monetary-reward-priming paradigm that allows for a systematic investigation of this perspective. We analyze this research to identify similarities and differences in how consciously and unconsciously perceived rewards impact three distinct aspects relevant to performance: decision making, task preparation, and task execution. We further discuss whether conscious awareness, in modulating the effects of reward information, plays a role similar to its role in modulating the effects of other affective information. Implications of these insights for understanding the role of consciousness in modulating goal-directed behavior more generally are discussed.     

Psychologists’ Evaluation of Bariatric Surgery Candidates Influenced by Patients’ Attachment Representations and Symptoms of Depression and Anxiety

This study examines whether patients self-reported attachment representations and levels of depression and anxiety influenced psychologists’ evaluations of morbidly obese patients applying for bariatric surgery. A sample of 250 patients (mean age 44, 84 % female) who were referred for bariatric surgery completed questionnaires to measure adult attachment and levels of depression and anxiety. Psychologists rated patients’ suitability for bariatric surgery using the Cleveland Clinic Behavioural Rating System (CCBRS), unaware of the results of the completed questionnaires. Attachment anxiety (OR = 2.50, p = .01) and attachment avoidance (OR = 3.13, p = .001) were found to be associated with less positive evaluations on the CCBRS by the psychologists, and symptoms of depression and anxiety mediated this association. This study strongly supports the notion that patients’ attachment representations influence a psychologist’s evaluation in an indirect way by influencing the symptoms of depression and anxiety patients report during an assessment interview. The clinical implications of these findings are discussed.     

Using stop signals to inhibit chronic dieters' responses toward palatable foods

Palatable foods in the environment can unintentionally trigger reactions to obtain them, which may interfere with dieting attempts. We tested a strategy to facilitate dieting behavior that makes use of behavioral stop signals that should instantly inhibit chronic dieters’ responses toward palatable foods. Participants performed a go/no-go task in which go cues and no-go cues (i.e., the behavioral stop signals) were presented with pictures of palatable foods and control objects. In Study 1, we tested the immediate behavioral effect of presenting stop signals near palatable foods in a reaction time paradigm. In Study 2 we assessed consumption of palatable food that had either consistently been associated with no-go cues, or not. Results show that no-go cues instantly inhibited responses toward palatable foods especially among chronic dieters. Moreover, across a one day period chronic dieters consumed less of a food that had consistently been associated with no-go cues. Stop signals thus appear a promising tool for chronic dieters to control behavior to palatable foods, and we discuss the merits and potential applications of this tool for facilitating dieting behavior.     

Implementation intentions as goal primes: Boosting self‐control in tempting environments

People often forget their long‐term strivings because their environment confronts them with attractive temptations. Previous research suggests that self‐control failures can be prevented by reminding people of their higher‐order goal. Therefore, we hypothesized that using implementation intentions as a tool to directly re‐activate people's higher‐order goal in tempting situations would effectively enhance self‐control. We tested this in the domain of dieting behavior. Results demonstrated that this specific planning strategy activated the dieting goal for unsuccessful dieters when exposed to tempting food cues (Study 1) and reduced their consumption of calorically dense food across 2 weeks (Study 2) compared to those in control conditions. This suggests that preparing people to think of their higher‐order goal when tempted can be used to protect ongoing goal striving. Appealing to higher‐order goals potentially makes implementation intentions flexible instruments of self‐regulation as this should trigger motivated behavior to reach goals and initiate various goal‐instrumental actions.

Hot or not: visceral influences on coping planning for weight loss attempts

The current studies aimed to examine how either or not being hungry (hot vs. cold state) affects uninformed (i.e. without specific instructions) coping planning for maintaining goal-directed behaviour in weight loss attempts. We hypothesised that being hungry is beneficial both for (1) increasing awareness of potentially challenging situations and for (2) planning how to cope with these situations. The first hypothesis was supported, whereas the second was not, as it was found that satiated participants constructed better quality coping plans than hungry participants. It appears that awareness of potentially challenging situations when hungry does not necessarily translate into better coping planning. Although coping planning appears to be a promising strategy for maintaining goal-directed behaviour, future research should focus on visceral states to improve its use.
