Higher order influences on evaluative priming: Processing styles moderate congruity effects

A growing body of research challenges the automaticity of evaluative priming (EP). The present research adds to this literature by suggesting that EP is sensitive to processing styles. We relied on previous research showing that EP is determined by the extent to which the prime and the target events on a given trial are processed as a unified compound. Here, we further hypothesised that processing styles encouraging the inclusion of the prime to the target episode support congruity effects, whereas processing styles that enhance the exclusion of the prime from the target episode interrupt (or reverse) these effects. In Experiment 1, a preceding similarity search task produced a congruity effect, whereas a dissimilarity search task eliminated and (non-significantly) reversed this effect. In Experiments 2 and 3, we replicated and extended these findings using a global/local processing manipulation. Overall, these findings confirm that EP is flexible, open to top-down influences and strategic regulation.     

Masked emotional priming: A double dissociation between direct and indirect effects reveals non-conscious processing of emotional information beyond valence

We demonstrate non-conscious processing beyond valence by employing the masked emotional priming paradigm (Rohr, Degner, & Wentura, 2012) with a stimulus-onset asynchrony (SOA) variation. Emotional faces were briefly presented and directly masked, followed by the target face, using a SOA of either 43 ms or 143 ms. Targets were categorized as happy, angry, fearful, or sad. With short SOA, we replicated the differentiated priming effect within the negative domain (i.e., angry differentiate from fearful/sad). A direct test of prime awareness indicated that primes could not be discriminated consciously in this condition. With long SOA, however, we did not observe the priming effect whereas the direct test indicated some degree of conscious processing. Thus, indirect effects dissociated from direct effects in our study, an indication for non-conscious processing. Thereby, the present study provides evidence for non-conscious processing of emotional information beyond a simple positive-negative differentiation.     

Testosterone facilitates the sense of agency

Sense of agency (SoA) refers to feelings of being in control of one’s actions. Evidence suggests that SoA might contribute towards higher-order feelings of personal control – a key attribute of powerful individuals. Whether testosterone, a steroid hormone linked to power in dominance hierarchies, also influences the SoA is not yet established. In a repeated-measures design, 26 females participated in a double-blind, placebo-controlled trial to test the effects of 0.5 mg testosterone on SoA, using an implicit measure based upon perceived shifts in time between a voluntary action and its outcome. Illusions of control, as operationalized by optimism in affective forecasting, were also assessed. Testosterone increased action binding but there was no significant effect on tone binding. Affective forecasting was found to be significantly more positive on testosterone. SoA and optimistic expectations are basic manifestations of power which may contribute to feelings of infallibility often associated with dominance and testosterone.     

More efficient,perhaps, but at what price? Pleasure and enjoyment responses to high-intensity interval exercise in low-active women with obesity

ObjectivesFewer than 1.5% of women with obesity in the USA are physically active at recommended levels. High-intensity interval exercise (HIIE) has been proposed as a possible solution to the problem of low activity, based on the dual promise of accelerating the accrual of benefits while reducing the time commitment. However, concerns have been raised about the appeal and sustainability of HIIE. The purpose of this study was to compare during-exercise affective valence and post-exercise enjoyment in response to a bout of HIIE and a longer, isocaloric bout of moderate-intensity continuous exercise (MICE).DesignWithin-subjects experiment.MethodsLow-active women with obesity (N = 24) completed one bout of HIIE (3-min warm-up, four 3-min intervals of recumbent cycling at 115% of Watts at the ventilatory threshold, four 2-min periods of active recovery at 85% of Watts at the ventilatory threshold, 5-min cool-down) and one bout of MICE (3-min warm-up, 25 min of recumbent cycling at 90% of Watts at the ventilatory threshold, 5-min cool-down) in counterbalanced order. The Feeling Scale (FS) was administered during exercise and the Physical Activity Enjoyment Scale (PACES) was administered after cool-down.ResultsDifferences were found for both FS (condition by time interaction: p < 0.001, η² = 0.27) and PACES (p = 0.04, d = −0.38), with both outcomes favoring MICE.ConclusionsThe lower pleasure and enjoyment associated with HIIE compared to MICE underscore the importance of considering not only physiological adaptations but also the appeal and sustainability of HIIE for low-active women with obesity.     

Post-training infusion of glutamate into the bed nucleus of the stria terminalis enhanced inhibitory avoidance memory: An effect involving norepinephrine

This study examined an interaction between glutamate and norepinephrine in the bed nucleus of the stria terminalis (BNST) in modulating affective memory formation. Male Wistar rats with indwelling cannulae in the BNST were trained on a one-trial step-through inhibitory avoidance task and received pre- or post-training intra-BNST infusion of glutamate, norepinephrine or their antagonists. Results of the 1-day test indicated that post-training intra-BNST infusion of dl-2-amino-5-phosphonovaleric acid (APV) impaired retention in a dose- and time-dependent manner, while infusion of glutamate had an opposite effect. Co-infusion of 0.2 μg glutamate and 0.02 μg norepinephrine resulted in marked retention enhancement by summating non-apparent effects of the two drugs given at a sub-enhancing dose. The amnesic effect of 5.0 μg APV was ameliorated by 0.02 μg norepinephrine, while the memory enhancing effect of 1.0 μg glutamate was attenuated by 5.0 μg propranolol. These findings suggest that training on an inhibitory avoidance task may alter glutamate neurotransmission, which by activating NMDA receptors releases norepinephrine to modulate memory formation via β adrenoceptors in the BNST.     

季节性情感障碍存在记忆损伤吗？

季节性情感障碍(Seasonal Affective Disorder, SAD)与轻度到中度的临床抑郁有类似的症状,它通常发生于季节性日照不足的地区。造成该障碍的一个可能原因是褪黑素分泌不足。与非季节性抑郁相比, 季节性抑郁的记忆损伤尚未得到充分研究。以往的研究也发现了一些类似于非季节性抑郁的记忆损伤, 但通常很少达到统计的显著性, 且其采用的测验任务也缺乏分辨力, 未能对损伤进行足够的细节描述。这里对有关文献做一个综述。     

Young children's affective decision-making in a gambling task: Does difficulty in learning the gain/loss schedule matter?

This research investigated the development of affective decision-making (ADM) during early childhood, in particular role of difficulty in learning a gain/loss schedule. In Experiment 1, we administrated the Children's Gambling Task (CGT) to 60 Chinese children aged 3 and 4, replicating the results obtained by Kerr and Zelazo [Kerr, A., & Zelazo, P. D. (2004). Development of “hot” executive function: The Children's Gambling Task. Brain and Cognition, 55, 148–157]. In Experiment 2, the CGT was modified to make it easier for young children to learn the gain/loss schedule by increasing delayed loss frequency and magnitude in the disadvantageous deck, and a larger sample (181 children aged 3–5) was assessed. Age-differences between 3- and 4-year-olds, rather than 4- and 5-year-olds, showed that ADM develops rapidly between 3 and 4 years. The reduction of the difficulty in learning the gain/loss schedule provides the basis for an account of the development of young children's AMD.     

Psychophysiological evidence of response conflict and strategic control of responses in affective priming

This experiment investigated the role of conflict in the response and evaluative categorization systems in the affective congruency effect using event-related brain potentials (ERPs). Participants completed a primed evaluative decision task in which the proportion of congruent to incongruent trials was manipulated. The size of the affective congruency effect increased along with the proportion of congruent trials. ERP data identified the locus of this effect in the response system: the lateralized readiness potential (LRP) showed that preferential response activation occurred in motor cortex following prime onset, and the fronto-central N2 (conflict monitoring) component indicated that conflict occurred when the response activated by the prime differed from the target response, irrespective of the affective congruency of the prime and target. The extent of this conflict covaried with strategic processing of primes, as participants directed less attention to primes that were likely to elicit conflict. These data support a response conflict account of affective congruency effects in the evaluative decision task and indicate that strategic control of attention is important in determining the extent to which conflict occurs.     

Neuroticism, negative affect, and negative affect instability: Establishing convergent and discriminant validity using ecological momentary assessment

Few investigations have examined the role of affective instability within a broad model of general personality functioning. The present study employed self-report and ecological momentary assessments (EMA) to examine the relations between self-reported Five-Factor Model Neuroticism, EMA average negative affect, and EMA negative affect instability. Results suggest that Neuroticism and negative affect instability are related yet distinct constructs, and that Neuroticism better represents average negative affect across time. Results also suggest that negative affect instability is related to low Agreeableness and specific externalizing facets of Neuroticism, such as Angry Hostility and Impulsiveness. The implications of these findings and potential areas for future research are discussed.     

Organizational Justice,Change Anxiety,and Acceptance of Downsizing: Preliminary Tests of an AET-Based Model

This study tested an AET-based model that integrates cognitions (justice perceptions) and emotions (change anxiety) to explain the effects of change program characteristics on employees' acceptance of downsizing and other work attitudes. Seventy-one employees from an organization that was undergoing downsizing participated in the study. Path analyses and a Q index of .992 offered preliminary support for the proposed model by showing that procedural justice and change anxiety explained the effects of change management procedures on acceptance of downsizing, while interactional justice and change anxiety explained the effects of the quality of change communications on trust in the change managers. Although distributive justice did not have the predicted direct effect on employee morale, it helped explain the effects of procedures on acceptance of change and morale by helping reduce anxiety about the change. Together, these findings support the utility of an AET-based framework in helping understand employee responses to downsizing.
