Exercise based interventions for alcohol use disorder: A comment on motivational aspects of participation

Exercise based treatment for alcohol use disorders have shown an impact on mental health (e.g., depression or anxiety), and alcohol outcomes (e.g., craving or abstinence). However, there is a lack of information on the role of motivational aspects of participation in the process of designing exercise interventions for alcohol use disorder. This study aims to examine: (1) whether motivational aspects are taken into account when the type and delivery method of exercise interventions are chosen; (2) whether motivational aspects are taken into account post intervention; and (3) whether there are different traditions regarding payment for participants. A systematic search was conducted to identify eligible studies in order to investigate the impact of motivational aspects including payment for participation. Twelve samples including ten to 620 participants were investigated. Participants were predominantly male and in their 40s, ranging from 20 to 69 years. Aerobic exercise (running, walking, fitness) either in a group or individual condition is the most frequently used exercise form. Two studies included ball games or cycling, while only one study offered the opportunity to choose between a wide range of sports. Motivational aspects are mentioned explicitly in half of the studies, mostly with regard to adherence to participation and social integration as the reason for using a group condition. Achievement is mentioned in two studies but not explicitly with regard to planning the intervention design. Five studies include payment for participation in exercise. Findings of the present study identify that motivational aspects for participation are rarely involved in the planning of an exercise intervention. With regard to the specific psychosocial vulnerability of an alcohol use disorder population, this should be an important aspect of further research studies.     

Seasonal Variations in Color Preference

We investigated how color preferences vary according to season and whether those changes could be explained by the ecological valence theory (EVT). To do so, we assessed the same participants’ preferences for the same colors during fall, winter, spring, and summer in the northeastern United States, where there are large seasonal changes in environmental colors. Seasonal differences were most pronounced between fall and the other three seasons. Participants liked fall‐associated dark‐warm colors—for example, dark‐red, dark‐orange (brown), dark‐yellow (olive), and dark‐chartreuse—more during fall than other seasons. The EVT could explain these changes with a modified version of Palmer and Schloss’ (2010) weighted affective valence estimate (WAVE) procedure that added an activation term to the WAVE equation. The results indicate that color preferences change according to season, as color‐associated objects become more/less activated in the observer. These seasonal changes in color preferences could not be characterized by overall shifts in weights along cone‐contrast axes.     

Emotion and false memory: How goal-irrelevance can be relevant for what people remember

Elaborating on misleading information concerning emotional events can lead people to form false memories. The present experiment compared participants’ susceptibility to false memories when they elaborated on information associated with positive versus negative emotion and pregoal versus postgoal emotion. Pregoal emotion reflects appraisals that goal attainment or failure is anticipated but has not yet occurred (e.g., hope and fear). Postgoal emotion reflects appraisals that goal attainment or failure has already occurred (e.g., happiness and devastation). Participants watched a slideshow depicting an interaction between a couple and were asked to empathise with the protagonist's feelings of hope (positive pregoal), happiness (positive postgoal), fear (negative pregoal), or devastation (negative postgoal); in control conditions, no emotion was mentioned. Participants were then asked to reflect on details of the interaction that had occurred (true) or had not occurred (false), and that were relevant or irrelevant to the protagonist's goal. Irrespective of emotional valence, participants in the pregoal conditions were more susceptible to false memories concerning goal-irrelevant details than were participants in the other conditions. These findings support the view that pregoal emotions narrow attention to information relevant to goal pursuit, increasing susceptibility to false memories for irrelevant information.     

Why are negative behaviours likely to be immediately invoked traits? The effects of valence and frequency on spontaneous trait inferences

People make trait inferences immediately when observing others’ behaviours. Previous studies reported that this spontaneous trait inference (STI) occurs more strongly from negative behaviours than from positive behaviours. However, what is responsible for this negativity bias in STI is unclear. In this study, two experiments investigated the effects of valence (an event's affective positivity or negativity) and frequency (how frequently the behaviour is observed in everyday life) on the occurrence of STI using an adapted version of a savings‐in‐relearning paradigm. Experiment 1 revealed that only valence affected the frequent occurrence of STI. In addition, the instructions to suppress impression formation or to focus attention on an actor's face made no difference to the results. In Experiment 2, the negativity bias in STIs was shown a week after exposure to the behavioural stimuli. These results suggest that the negativity bias in STIs occurs robustly, and the negative valence of observed behaviour is mostly responsible for the negativity bias in STI. The importance of immediate categorization of negative stimuli is discussed in terms of ecological priority.     

调节聚焦对期限效果的影响

结合调节聚焦探讨了期限的时长、结果框架及效价对期限效果的影响。结果表明,防御聚焦个体认为期限的阻碍效果更大,且调节聚焦对前述变量与期限效果的关系具有调节作用:4分钟期限中防御聚焦组认为期限的阻碍效果更大,8分钟期限中则相反,12和16分钟期限中均无显著差异;收益框架下促进聚焦组认为期限对任务表现的阻碍作用更大,促进聚焦组在正效价条件下认为收益框架下期限对策略使用的阻碍作用更大,但在负效价条件下则相反。     

情绪效价和唤醒对熟悉性和回想的不同影响

本研究检验了情绪的效价和唤醒对记忆提取阶段熟悉性过程和回想过程的影响及其心理机制。结果发现,编码阶段无分心任务时,积极图片的高、低自信再认准确率均高于消极图片,而唤醒对于高自信再认准确率的影响只限于消极图片;在编码阶段设置分心任务时,发现积极和消极的高唤醒图片的高自信再认准确率显著高于低唤醒图片。这些结果说明情绪的效价影响了熟悉性和回想两类记忆过程,而唤醒只影响回想过程,效价效应是编码阶段被试调用认知资源对积极图片进行精细加工的结果,而唤醒对回想过程的影响是自动编码高唤醒刺激细节的结果。     

催产素对情绪识别的影响及其机制

催产素(oxytocin)被称为“社会键(social bonds)荷尔蒙”, 时刻影响着社会行为和认知, 其中包括情绪识别。目前, 关于催产素对情绪识别的影响主要有3种观点：(1)催产素选择性地促进个体对积极情绪的识别、减慢对消极情绪的识别; (2)催产素选择性地增强对消极情绪的识别; (3)催产素提高对所有情绪的识别, 与情绪效价无关。催产素影响情绪识别神经机制的研究主要集中在3个方面：情绪效价、性别差异和精神疾病。此外, 还运用社会显著假说解释催产素对情绪识别的作用。催产素可能对情绪识别障碍类精神疾病有潜在的治疗效果, 未来的研究应深入探究催产素与情绪效价的关系, 考虑性别等个体因素的影响, 进一步探讨催产素的临床应用并拓展研究范围。

未来时间距离对自我行为表征的影响：评价内容效价的作用

先前研究表明,对于自我行为,相对于近期过去,个体对远期过去正性行为的表征更倾向于特质性和抽象性,但对负性行为的表征未获得明确的类似效应（申之美等,2010）。本研究以特质性和行动性行为描述句子为实验材料,通过两个实验考察了未来时间距离对自我正性行为和负性行为的表征特征的影响,以进一步探讨评价内容的效价特性对于建构水平的心理距离效应的调节作用。实验结果发现,相对于近期未来,被试对远期未来自我的正性行为更倾向于抽象的特质性表征,但在负性行为上未获得类似效应。个体对未来自我行为的正性期待和负性回避倾向可能是自我行为表征缺乏距离效应的心理机制。     

Oral kinematics: examining the role of edibility and valence in the in-out effect

Previous research has revealed a stable preference for words with inward consonantal-articulation patterns (from the front to the back of the mouth; e.g. BENOKA), over outward-words (from the back to the front; e.g. KENOBA). Following the oral approach-avoidance account suggesting that the in–out effect is due to the resemblance between consonantal-articulations patterns and ingestion/expectoration, recent findings have shown that when judging inward-outward names for objects with particular oral functions, valence did not modulate the effect while the oral function did. To replicate and examine further the role of edibility and valence in shaping the in–out effect, we asked participants (N?=?545) to rate inward and outward names for edible and non-edible products while controlling for valence. Results revealed that the motor-to-affect link was only observed for edible products, regardless of valence.
