Manipulating affective state influences conditioned appetitive responses

Affective states influence how individuals process information and behave. Some theories predict emotional congruency effects (e.g. preferential processing of negative information in negative affective states). Emotional congruency should theoretically obstruct the learning of reward associations (appetitive learning) and their ability to guide behaviour under negative mood. Two studies tested the effects of the induction of a negative affective state on appetitive Pavlovian learning, in which neutral stimuli were associated with chocolate (Experiment 1) or alcohol (Experiment 2) rewards. In both experiments, participants showed enhanced approach tendencies towards predictors of reward after a negative relative to a positive performance feedback manipulation. This increase was related to a reduction in positive affect in Experiment 1 only. No effects of the manipulation on conditioned reward expectancies, craving, or consumption were observed. Overall, our findings support the idea of counter-regulation, rather than emotional congruency effects. Negative affective states might therefore serve as a vulnerability factor for addiction, through increasing conditioned approach tendencies.     

Impact of Low Social Preference on the Development of Depressive and Aggressive Symptoms: Buffering by Children’s Prosocial Behavior

Holding a low social position among peers has been widely demonstrated to be associated with the development of depressive and aggressive symptoms in children. However, little is known about potential protective factors in this association. The present study examined whether increases in children’s prosocial behavior can buffer the association between their low social preference among peers and the development of depressive and aggressive symptoms in the first few school years. We followed 324 children over 1.5 years with three assessments across kindergarten and first grade elementary school. Children rated the (dis)likability of each of their classroom peers and teachers rated each child’s prosocial behavior, depressive and aggressive symptoms. Results showed that low social preference at the start of kindergarten predicted persistent low social preference at the start of first grade in elementary school, which in turn predicted increases in both depressive and aggressive symptoms at the end of first grade. However, the indirect pathways were moderated by change in prosocial behavior. Specifically, for children whose prosocial behavior increased during kindergarten, low social preference in first grade elementary school no longer predicted increases in depressive and aggressive symptoms. In contrast, for children whose prosocial behavior did not increase, their low social preference in first grade elementary school continued to predict increases in both depressive and aggressive symptoms. These results suggest that improving prosocial behavior in children with low social preference as early as kindergarten may reduce subsequent risk of developing depressive and aggressive symptom.     

Are space and time automatically integrated in episodic memory?

The aim of the present study was to determine to what extent spatial and temporal features are automatically integrated during encoding in episodic memory. Both nameable and non-nameable stimuli were presented sequentially at different locations on a computer screen. Mixed and pure blocks of trials were used. In the mixed blocks participants were instructed to focus either on the spatial or the temporal order of the objects, as on the majority of the trials recall of this feature was tested (expected trials). However, on a few trials participants had to reproduce the other feature (unexpected trials). In the pure blocks either the spatial or the temporal order of the objects was tested on all trials. More errors were made on unexpected than on expected trials of the mixed blocks. Moreover, no primacy or recency effects were found when performance on the spatial task was plotted as a function of the temporal position. These results suggest that spatial information and temporal order information rely on separate encoding processes.     

The effectiveness of a proactive coping intervention targeting self-management in diabetes patients

Objective: The study’s aim was to investigate psychological, behavioral and medical long-term outcomes of an existing self-management intervention targeting the development of proactive coping skills (e.g. goal setting and identifying barriers) in type 2 diabetes patients. The study aimed to replicate prior research showing the intervention’s effectiveness, and to extend it by (a) adding booster sessions and (b) prolonging the period of follow-up measurement to capture long-term effects.

Design/outcome measures: A total of 141 type 2 diabetes patients were included in the intervention. The intervention employed a 5-step approach to target proactive coping skills. Psychological (e.g. proactive coping and self-efficacy) and behavioural variables (e.g. self-care, diet and physical activity) were assessed at baseline (T1), after the initial phase of the intervention (T2), after the booster phase (T3) and at follow-up (T4), comprising a total period of 15 months. Medical variables were assessed at T1 and T4.

Results: Employing piecewise Latent Growth Curve Modelling, results showed that participants improved on all psychological and behavioural variables during the initial phase and maintained these improvements over 12 months. The booster phase yielded no further improvements. Mixed findings were obtained on medical outcomes.

Conclusion: The original intervention is effective, but the added value of the booster sessions is uncertain.     

Identifying the ‘if’ for ‘if-then’ plans: Combining implementation intentions with cue-monitoring targeting unhealthy snacking behaviour

Implementation intentions aimed at changing unwanted habits require the identification of personally relevant cues triggering the habitual response in order to be effective. To facilitate successful implementation intention formation, in the present study, planning was combined with cue-monitoring, a novel way to gain insight into triggers for unhealthy snacking. It was tested whether keeping a cue-monitoring diary and tailoring implementation intentions accordingly improves plan effectiveness. A 2 Monitoring (cue-monitoring, control)?×?2 Planning (implementation intention, goal intention) between subjects design was adopted. Participants (N = 161) monitored their unhealthy snacking behaviour for a week using either a cue-monitoring or a control diary. Participants then formulated a goal intention or an implementation intention tailored to their personal cue. Snacking frequency and caloric intake from unhealthy snacks were examined using a seven-day snack diary. The results did not indicate an interaction but yielded a main effect of Monitoring. Cue-monitoring either or not combined with implementation intentions reduced unhealthy snacking behaviour compared with control. Findings emphasise the effectiveness of cue-monitoring, suggesting that on the short term, cue-monitoring suffices to decrease unhealthy snacking, without additional benefit from planning. Future research should examine whether supplementing cue-monitoring with implementation intentions is required to establish long-term behaviour change maintenance.     

Feminism as Revolutionary Practice: From Justice and the Politics of Recognition to Freedom

In the 1980s extra‐parliamentary social movements and critical theories of race, class, and gender added a new sociocultural understanding of justice—recognition—to the much older socioeconomic one. The best‐known form of the struggle for recognition is the identity politics of disadvantaged groups. I argue that there is still another option to conceptualize their predicament, neglected in recent political philosophy, which understands exclusion not in terms of injustice, more particularly a lack of sociocultural recognition, but in terms of a lack of freedom. I draw my inspiration from Hannah Arendt's model of political action. Arendt diagnoses exclusion not solely as a mode of injustice, but as a lack of participation and public freedom. Consequently, she advocates a struggle for participation, political equality, and freedom as a strategy for emancipation or empowerment. Arendt could help feminists see that collective empowerment is made possible not by a shared identity (the target of poststructuralist critics) but by common action in the service of a particular worldly issue or common end. In other words, feminists would do well to appreciate the revolutionary quality and heritage of the feminist movement better, that is, its character as a set of practices of freedom.     

Affect-congruent approach and withdrawal movements of happy and angry faces facilitate affective categorisation

Increasing evidence indicates that evaluation of affective stimuli facilitates the execution of affect-congruent approach and avoidance responses, and vice versa. These effects are proposed to be mediated by increases or decreases in the relative distance to the stimulus, due to the participant's action. In a series of experiments we investigated whether stimulus categorisation is similarly influenced when changes in this relative distance are due to movement of the stimulus instead of movements by the participant. Participants responded to happy and angry faces that appeared to approach (move towards) or withdraw (move away) from them. In line with previous findings, affective categorisation was facilitated when the movement was congruent with stimulus valence, resulting in faster and more correct responses to approaching happy and withdrawing angry faces. These findings suggest that relative distance indeed plays a crucial role in approach–avoidance congruency effects, and that these effects do not depend on the execution of movements by the participant.     

Fitting decisions: Mood and intuitive versus deliberative decision strategies

We investigated the influence of the compatibility between mood and decision strategies on the subjective value of a decision outcome. Several studies have provided evidence for the idea that a sad mood induces people to analyse information carefully, probably fitting well with a deliberative decision strategy. In a happy mood, people tend to act more strongly on their feelings, probably fitting well with an intuitive decision strategy. However, sometimes the situation demands the use of decision strategies that seem incompatible with mood states. We expected that decision makers would value a decision outcome higher in the case of a fit between mood and decision strategy than in the case of a non-fit. After a mood manipulation, participants were instructed to decide either based on their first affective reaction or after deliberation. Results confirmed our expectations: fitting decisions enhanced the subjective value of a decision outcome.     

"Instant success": turning temptations into cues for goal-directed behavior

Contrary to lay intuition, counteractive control theory posits that tempting food cues can help individuals to act in accordance with their long-term dieting goal. However, studies have shown that temptations trigger goal-directed behavior only in successful but not in unsuccessful self-regulators. The aim of the present study was to test whether it is possible to create facilitated temptation-goal associations in unsuccessful dieters using implementation intentions (e.g., "If I see or smell chocolate then I will follow my goal to diet") and whether this indeed stimulates more successful self-regulation. It was found that implementation intentions linking a temptation to a dieting goal lead to self-perceived improved resistance to (Study 1) as well as reduced consumption (Study 2) of tempting snacks compared to a control condition. Moreover, Study 2 revealed that the reduced snack consumption was indeed related to facilitated temptation-goal associations in participants who had formed implementation intentions.     

Disrupting reconsolidation: pharmacological and behavioral manipulations

We previously demonstrated that disrupting reconsolidation by pharmacological manipulations "deleted" the emotional expression of a fear memory in humans. If we are to target reconsolidation in patients with anxiety disorders, the disruption of reconsolidation should produce content-limited modifications. At the same time, the fear-erasing effects should not be restricted to the feared cue itself considering that fear generalization is a main characteristic of anxiety disorders. In Experiment I and Experiment I(b), we addressed these issues using a within-subject differential startle fear conditioning paradigm and a test of fear generalization. In Experiment II, we tested whether a behavioral approach targeting the reconsolidation through extinction learning was also effective in weakening the original fear memory. A behavioral procedure is evidently preferred over drug manipulations provided that similar effects can be obtained. Here, the extinction procedure subsequent to retrieval did not "erase" the emotional expression of the fear memory as the retrieval techniques (i.e., reminder shocks and reacquisition) unveiled a return of the startle fear response to the fear-relevant stimuli. In contrast, β-adrenergic receptor blockade during reconsolidation selectively deleted the fear-arousing aspects of the memory (i.e., startle fear response) along with its category-related information. The pharmacological manipulation rendered the core memory trace too weak to observe fear generalization after successful reacquisition. Hence, relearning following the disruption of reconsolidation seems to be qualitatively different from initial learning. Our findings demonstrate that disrupting reconsolidation by pharmacological manipulations, although selective, undermines the generalization of fear, a key feature of anxiety disorders.
