Together or apart: when goals and temptations complement versus compete

This research examined how the presentation of items related to goals and temptations influences the dynamic of self-regulation, as reflected in evaluation and choice. The authors found that when items, such as healthy and unhealthy foods or academic and leisure activities, are presented together in a unified choice set (e.g., in 1 image) and seem to complement each other, people express a positive evaluation of and a preference for tempting items. Conversely, when the items are presented apart from each other in 2 choice sets (e.g., 2 images) and seem to compete with each other, people express a positive evaluation of and preference for goal items.     

Unsure what the future will bring? You may overindulge: Uncertainty increases the appeal of wants over shoulds

This paper examines the effect of uncertainty about the future on whether individuals select want options (e.g., junk foods, lowbrow films) or instead exert self-control and select should options (e.g., healthy foods, highbrow films). Consistent with the ego-depletion literature, which suggests that self-control resembles an exhaustible muscle, coping with uncertainty about what the future may bring reduces self-control resources and increases individuals’ tendency to favor want options over should options. These results persist when real uncertainty is induced, when the salience of naturally-arising uncertainty is heightened and when individuals are able to make choices contingent upon the outcomes of uncertain events. Overall, this work suggests that reducing uncertainty in a decision maker’s environment may have important spillover effects, leading to less impulsive choices.     

Reduce temptation or resist it? Experienced temptation mediates the relationship between implicit evaluations of unhealthy snack foods and subsequent intake

A more negative implicit evaluation of unhealthy food stimuli and a more positive implicit evaluation of a weight-management goal have been shown to predict lower consumption of unhealthy food. However, the associations between these evaluations, temptation to indulge and consumption of unhealthy food remain unclear. The current study investigated whether temptation would mediate the relationship between implicit food and goal evaluations and consumption (resembling an antecedent-focused route to self-control of eating), or whether those evaluations would moderate the relationship between temptation and consumption (resembling a response-focused route). A sample of 156 women (17–25 years), who tried to manage their weight through healthy eating, completed two implicit association tasks assessing implicit food and goal evaluations, respectively. Intake of four energy-dense snack foods was measured in a task disguised as a taste test, and participants reported the strength of experienced temptation to indulge in the snacks offered. Negative implicit food evaluation was associated with lower snack intake, and temptation mediated this relationship. Implicit goal evaluation was unrelated to both temptation strength and snack consumption. The findings contribute to an understanding of how negative implicit unhealthy food evaluation relates to lower consumption, namely through the mediation of temptation to indulge in those foods.     

Implicit identification of irrelevant local objects interacts with global/local processing of hierarchical stimuli

This work aimed at studying interactions between automatic object identification and global/local perceptual processing. We designed a paradigm in which participants were presented with pairs of hierarchically organized items, composed of global forms made up of local forms. Both global and local forms could represent either objects or non-objects. Subjects were instructed to detect whether the two hierarchical items composing a pair were identical or different. In a dissimilar pair, items differed at one level (target level), the other level, made of similar forms on both sides, was irrelevant to perform the task. We hypothesized that the automatic identification of object could affect the global precedence principle defined by Navon. In agreement with our hypothesis, we found that when the irrelevant level was made of objects, the global precedence effect was reversed. In contrast, the irrelevant level had no effect when the target level included only objects, or when the irrelevant level was made of non-object, the global precedence principle was being preserved in these cases. This interaction is compatible with the existence of two distinct processes working in parallel, namely automatic identification and structural analysis, that could either interfere or act together for the detection of differences.     

A variable mapping task produces symmetrical interference between global information and local information

When processing global and local aspects of compound visual figures, a robust finding is that global targets are detected faster and more accurately than local targets. Moreover, unidirectional interference is often observed. Despite the convincing evidence that global information and local information are available together, when attention is focused on the global level, items from the local level often have very little, if any, effect on behavior. If local information is available with global information, then why is global dominance so often observed under such a wide range of conditions? This paper is concerned with the fate of the ignored, and apparently ineffective, local distractors. In our experiments, at least one critical factor was stimulus-response (S-R) mapping. We compared a consistent S-R task, which facilitated a speed advantage for global, with a variable S-R task, which required a higher degree of semantic analysis for each stimulus. The two tasks produced large differences in behavior, showing unidirectional interference in the consistent S-R task, and strong bidirectional interference in the variable S-R task. Thus, the identity of ignored local distractors was available, even under conditions that favored focused attention to global information. The results provide support for a model in which global processing proceeds more quickly at early perceptual stages and in which local processing can catch up if processing demands are increased at later stages.     

Tracing Attitude Expressions: An Eye‐Tracking Study

Attitudes represent object evaluations, comprising complex underlying cognitive and affective knowledge structures. When people are asked to judge an object, they can use their primary response (i.e., the immediate object‐evaluation linkage) or underlying affective and cognitive knowledge structures. In many situations, a primary response satisfices, but if not, more elaboration is required. Both processes are fundamentally different but may lead to the same attitude. For monitoring underlying processes during attitude expression, we developed an innovative eye‐tracking procedure using eye‐gaze on response scale options. This procedure was applied in three studies to identify the extent to which elaboration differs for attitude objects with weak or strong, univalent or mixed object evaluations (i.e., univalent, neutral and ambivalent). In Study 1, the overall judgment preceded processing of more specific affective and cognitive linkage evaluations. In Studies 2 and 3, the order was reversed, and affective and cognitive bases were assessed prior to overall attitude outcomes. For attitude objects with strong univalent or strong mixed object evaluations, we found similar outcomes on underlying processes. For weak object evaluations, cognition was found to be more predictive and easily accessible if an overall judgment was required first; affect for these objects was more predictive if people had to elaborate on affect and cognition first. We concluded that both affective and cognitive attitudes may require substantial elaboration, albeit in different situations. Copyright © 2015 John Wiley & Sons, Ltd.

Global and local evaluations of public speaking performance in social anxiety

Differences in the relative use of global and local information (seeing the forest vs. the trees) may explain why people with social anxiety often do not benefit from corrective feedback, even though they pay close attention to details in social situations. In the current study, participants high (n = 43) or low (n = 47) in social anxiety symptoms gave a series of brief speeches, and then self-rated their speaking performance on items reflecting global and local performance indicators (self-assessment) and also received standardized performance feedback from an experimenter. Participants then completed a questionnaire asking how they thought the experimenter would rate their performance based on the feedback provided (experimenter assessment). Participants completed the self- and experimenter assessments again after 3 days, in addition to a measure of postevent processing (repetitive negative thinking) about their speech performance. Results showed that, as hypothesized, the High SA group rated their performance more negatively than the Low SA group. Moreover, the High SA group's ratings of global aspects of their performance became relatively more negative over time, compared to their ratings of local aspects and the Low SA group's ratings. As expected, postevent processing mediated the relationship between social anxiety group status and worsening global performance evaluations. These findings point to a pattern of progressively more negative global evaluations over time for persons high in social anxiety.     

In the trenches of real-world self-control: neural correlates of breaking the link between craving and smoking

Successful goal pursuit involves repeatedly engaging self-control against temptations or distractions that arise along the way. Laboratory studies have identified the brain systems recruited during isolated instances of self-control, and ecological studies have linked self-control capacity to goal outcomes. However, no study has identified the neural systems of everyday self-control during long-term goal pursuit. The present study integrated neuroimaging and experience-sampling methods to investigate the brain systems of successful self-control among smokers attempting to quit. A sample of 27 cigarette smokers completed a go/no-go task during functional magnetic resonance imaging before they attempted to quit smoking and then reported everyday self-control using experience sampling eight times daily for 3 weeks while they attempted to quit. Increased activation in right inferior frontal gyrus, pre-supplementary motor area, and basal ganglia regions of interest during response inhibition at baseline was associated with an attenuated association between cravings and subsequent smoking. These findings support the ecological validity of neurocognitive tasks as indices of everyday response inhibition.     

Lateralized goal framing: How health messages are influenced by valence and contextual/analytic processing

The effectiveness of health messages has been shown to vary due to the positive or negative framing of information, often known as goal framing. In two experiments we altered, the strength of the goal framing manipulation by selectively activating the processing style of the left or right hemisphere (RH). In Experiment 1, we found support for the contextual/analytic perspective; a significant goal framing effect was observed when the contextual processing style of the RH – but not the analytic processing style of the left hemisphere (LH) – was initially activated. In Experiment 2, support for the valence hypothesis was found when a message that had a higher level of personal involvement was used than that in Experiment 1. When the LH was initially activated, there was an advantage for the gain- vs. loss-framed message; however, an opposite pattern – an advantage for the loss-framed message – was obtained when the RH was activated. These are the first framing results that support the valence hypothesis. We discuss the theoretical and applied implications of these experiments.     

Construal levels and self-control

The authors propose that self-control involves making decisions and behaving in a manner consistent with high-level versus low-level construals of a situation. Activation of high-level construals (which capture global, superordinate, primary features of an event) should lead to greater self-control than activation of low-level construals (which capture local, subordinate, secondary features). In 6 experiments using 3 different techniques, the authors manipulated construal levels and assessed their effects on self-control and underlying psychological processes. High-level construals led to decreased preferences for immediate over delayed outcomes, greater physical endurance, stronger intentions to exert self-control, and less positive evaluations of temptations that undermine self-control. These results support a construal-level analysis of self-control.     

Injustice impairs self-regulation and affects food choice

Overweight and obesity are risk factors for a range of chronic diseases, many of them caused by excessive consumption of unhealthy foods and insufficient consumption of healthy foods. The present study aims to experimentally test the effect of being exposed to injustice on the intention to consume healthy and unhealthy foods, through self-regulation. We predicted that injustice decreases self-regulation which in turn increases the intention to consume unhealthy foods and decreases the intention to consume healthy foods. Undergraduate students (N = 175; 89% women; M_age = 24.28, SD = 7.36) were randomly exposed to a scenario describing an unjust or a just academic situation. In a subsequent allegedly unrelated task, participants were asked to indicate their intention to consume each of 26 food items (half depicting unhealthy foods and half healthy foods, random order) during the subsequent week. As expected, injustice decreased self-regulation which in turn increased the intention to consume unhealthy foods and decreased the intention to consume healthy foods. These results highlight the central importance of justice perceptions in the study of consumption and contribute to frame it in the study of the consequences of economic inequalities for nutrition.     

解释水平对自我控制的影响

解释水平理论认为自我控制是人们依据对事件整体的高解释水平方式而非局部的低解释水平方式做出决策和完成任务。对时间折扣、坚持和健康行为以及前瞻性自我控制的研究表明高解释水平会促进自我控制。高解释水平是通过改变对诱惑的加工(包含对诱惑的态度和诱惑的激活模式)来促进自我控制, 但这种促进作用会受到目标和任务属性(重要性、难度、效价、完成时间和呈现方式)以及解释水平线索属性(外显和内隐)的调节。解释水平理论视角下的自我控制研究可以拓宽自我控制双系统理论和资源理论的视野, 如提供可能的边界条件和认知机制。未来研究还需要深入挖掘解释水平影响自我控制的内在机制和生理基础, 重视心理距离的影响以及加强对自控能力的长期追踪研究。     

Serotonin enhances the impact of health information on food choice

Serotonin has been implicated in promoting self-control, regulation of hunger and physiological homeostasis, and regulation of caloric intake. However, it remains unclear whether the effects of serotonin on caloric intake reflect purely homeostatic mechanisms, or whether serotonin also modulates cognitive processes involved in dietary decision making. We investigated the effects of an acute dose of the serotonin reuptake inhibitor citalopram on choices between food items that differed along taste and health attributes, compared with placebo and the noradrenaline reuptake inhibitor atomoxetine. Twenty-seven participants attended three sessions and received single doses of atomoxetine, citalopram, and placebo in a double-blind randomised cross-over design. Relative to placebo, citalopram increased choices of more healthy foods over less healthy foods. Citalopram also increased the emphasis on health considerations in decisions. Atomoxetine did not affect decision making relative to placebo. The results support the hypothesis that serotonin may influence food choice by enhancing a focus on long-term goals. The findings are relevant for understanding decisions about food consumption and also for treating health conditions such as eating disorders and obesity.     

Modulation of taxonomic (versus thematic) similarity judgments and product choices by inducing local and global processing

Perceived similarity is influenced by both taxonomic and thematic relations. Assessing taxonomic relations requires comparing individual features of objects whereas assessing thematic relations requires exploring how objects functionally interact. These processes appear to relate to different thinking styles: abstract thinking and a global focus may be required to explore functional interactions whereas attention to detail and a local focus may be required to compare specific features. In four experiments we explored this idea by assessing whether a preference for taxonomic or thematic relations could be created by inducing a local or global perceptual processing style. Experiments 1–3 primed processing style via a perceptual task and used a choice task to examine preference for taxonomic (versus thematic) relations. Experiment 4 induced processing style and examined the effect on similarity ratings for pairs of taxonomic and thematically related items. In all cases processing style influenced preference for taxonomic/thematic relations.     

“I deserve a treat”: Exercise motivation as a predictor of post-exercise dietary licensing beliefs and implicit associations toward unhealthy snacks

ObjectiveTo explore whether exercise motivation predicted two of the potential mechanisms that may explain why individuals engage in unhealthy compensatory snack consumption following exercise; specifically (a) post-exercise conscious licensing beliefs, and (b) post-exercise implicit attitudes toward unhealthy snacks.DesignObservational study.MethodOne hundred and nineteen healthy participants completed a 40-min session of moderate intensity stationary cycling, and subsequently completed measures of explicit licensing and implicit associations toward unhealthy snack foods and drinks.ResultsIndividuals driven by more controlled (relative to autonomous) forms of exercise motivation reported greater compensatory licensing beliefs (Est = −0.08, p < 0.001) even after accounting for a number of relevant covariates. No significant relationship emerged between exercise motivation and implicit associations toward unhealthy snacks (Est = 0.12, p = 0.81).ConclusionThe findings demonstrate that exercise motivation may predict conscious licensing beliefs toward unhealthy snack foods and drinks post-exercise. Understanding the modifiable factors – such as exercise motivation – that predict post-exercise dietary beliefs is important for supporting individuals’ weight loss and health goals.     

Autism: Hard to Switch from Details to the Whole

It has long been proposed that individuals with autism exhibit a superior processing of details at the expense of an impaired global processing. This theory has received some empirical support, but results are mixed. In this research we have studied local and global processing in ASD and Typically Developing children, with an adaptation of the Navon task, designed to measure congruency effects between local and global stimuli and switching cost between local and global tasks. ASD children showed preserved global processing; however, compared to Typically Developing children, they exhibited more facilitation from congruent local stimuli when they performed the global task. In addition, children with ASD had more switching cost than Typically Developing children only when they switched from the local to the global task, reflecting a specific difficulty to disengage from local stimuli. Together, results suggest that ASD is characterized by a tendency to process local details, they benefit from the processing of local stimuli at the expense of increasing cost to disengage from local stimuli when global processing is needed. Thus, this work demonstrates experimentally the advantages and disadvantages of the increased local processing in children with ASD.     

Resisting temptation of unhealthy food: interaction between temptation-elicited goal activation and self-control

Counteractive control theory suggests that the cognitive accessibility of a goal in response to a temptation cue predicts self-regulation of behaviour consistent with that goal. The current study provided a novel test of this effect in the eating domain, exploring the moderating role of trait self-control. A sample of 124 women (18–25 years) completed a lexical decision task to assess cognitive accessibility of the weight-management goal after food temptation priming. Eating self-regulation was operationalised as unhealthy snack food intake measured in a task disguised as a taste-test. Participants completed trait self-control and temptation experience intensity measures. Cognitive accessibility predicted lower food intake, but only among high self-control participants. The relationship was mediated by temptation experience intensity: participants with high cognitive accessibility felt less tempted, and subsequently ate less food. Results suggest that changing the processes underlying the temptation experience, rather than the cognitive accessibility of a goal may more effectively enhance self-regulation among low self-control individuals.     

Statistical regularities guide the spatial scale of attention

Visual scenes contain information on both a local scale (e.g., a tree) and a global scale (e.g., a forest). The question of whether the visual system prioritizes local or global elements has been debated for over a century. Given that visual scenes often contain distinct individual objects, here we examine how regularities between individual objects prioritize local or global processing. Participants viewed Navon-like figures consisting of small local objects making up a global object, and were asked to identify either the shape of the local objects or the shape of the global object, as fast and accurately as possible. Unbeknown to the participants, local regularities (i.e., triplets) or global regularities (i.e., quadruples) were embedded among the objects. We found that the identification of the local shape was faster when individual objects reliably co-occurred immediately next to each other as triplets (local regularities, Experiment 1). This result suggested that local regularities draw attention to the local scale. Moreover, the identification of the global shape was faster when objects co-occurred at the global scale as quadruples (global regularities, Experiment 2). This result suggested that global regularities draw attention to the global scale. No participant was explicitly aware of the regularities in the experiments. The results suggest that statistical regularities can determine whether attention is directed to the individual objects or to the entire scene. The findings provide evidence that regularities guide the spatial scale of attention in the absence of explicit awareness.     

Where there is a way, is there a will? The effect of future choices on self-control

Choices often involve self-control conflicts such that options that are immediately appealing are less desirable in the long run. In the current research, the authors examine how viewing such a choice as one of a series of similar future choices rather than as an isolated decision decreases the preference for items requiring self-control. The authors show that (a) in a choice between a vice and a virtue, the share choosing vice increases when the decision is presented as one of a series of similar future choices versus when the same choice is viewed in isolation, and (b) the overall share choosing a vice increases when decisions are seen in connection with similar future choices. The findings contrast with the general wisdom that broader choice frames lead to the exercise of greater self-control. The authors propose that the context of similar future choices allows people to optimistically believe that they will choose a virtue in the future choice and hence provides them with a guilt-reducing justification to not exercise self-control in the present.
