Relationship Trajectories: A Meta-Theoretical Framework and Theoretical Applications

This article introduces a metatheoretical framework—the Relationship Trajectories Framework—that conceptualizes how human mating relationships develop across their complete time span, from the moment two people meet until the relationship ends. The framework depicts relationships as arc-shaped evaluative trajectories that vary on five dimensions: shape (which includes ascent, peak, and descent), fluctuation, threshold, composition, and density. The framework can depict single trajectories in isolation or two partners’ trajectories with respect to each other (dyadic trajectories). Two theoretical models demonstrate the generative power of the framework—the relationship coordination and strategic timing (ReCAST) model and the sociosexuality trajectory model—both of which integrate close relationships and evolutionary psychological perspectives on mating. Finally, additional examples illustrate how the framework can generate new research questions about core relationships topics.     

Quality home visits: Activities to promote meaningful interactions

Examination of and support for specific practices that promote high-quality home visiting are essential as family support programs continue to expand across the country. The current study used direct observation of 91 home visits across 41 home visitors to examine relations among interaction partners, content of the interactions, the home-visitors’ activities, and quality of home-visitors’ practices and family-members’ engagement within programs funded by the Maternal, Infant, and Early Childhood Home Visiting program. More time spent in triadic interactions focused on child-related content, as measured by the Home Visit Rating Scale-Revised, was related to higher quality of family engagement in home visits, as measured with the Home Visit Observation Rating Scales. Time spent in adult-focused interactions and administrative tasks, however, was related to lower quality of home-visiting practices and family engagement. Implications for research and practice are discussed.     

员工负性情绪对情绪劳动策略的影响

情绪劳动指的是员工在工作中按照组织的要求来调节自己的情绪感受和表达, 是服务行业普遍关注的问题。本研究基于自我调节理论(Self-Regulation Theory), 探讨了员工个体内负性情绪对情绪劳动策略的影响效应, 以及个体间水平上员工工作年限和情绪智力对该效应的跨层次调节作用。通过分析收集自210名呼叫中心员工14个工作日的追踪数据, 本研究发现员工每天的负性情绪显著抑制了深层动作; 工作年限和情绪智力显著调节了个体内负性情绪对情绪劳动策略的影响效应。数据分析结果支持了情绪劳动的研究中自我调节理论的作用, 本研究也据此讨论了理论意义和实践应用价值。     

If it is easy to remember,then it is not secure: Metacognitive beliefs affect password selection

In this research, we applied current theories of metacognition to study computer security and tested the idea that users' password selection is affected by the metacognitive belief that if a password is memorable, then it is not secure. In two experiments, different types of eight‐character passwords and longer, more secure sentences were presented. Participants rated perceived memorability and perceived security of the passwords and indicated whether they would use them in a critical and in a noncritical service. The results confirmed the belief. Sentences that are in fact highly secure and perceived as highly memorable were also perceived as weak passwords. The belief strongly affected password selection for critical services, but it had no effect on noncritical services. In sum, long sentences are a particularly interesting type of password because they meet both security and memorability criteria, but their use is limited by a false belief.     

Doing Despite Disliking: Self‐regulatory Strategies in Everyday Aversive Activities

We investigated the self‐regulatory strategies people spontaneously use in their everyday lives to regulate their persistence during aversive activities. In pilot studies (pooled N = 794), we identified self‐regulatory strategies from self‐reports and generated hypotheses about individual differences in trait self‐control predicting their use. Next, deploying ambulatory assessment (N = 264, 1940 reports of aversive/challenging activities), we investigated predictors of the strategies' self‐reported use and effectiveness (trait self‐control and demand types). The popularity of strategies varied across demands. In addition, people higher in trait self‐control were more likely to focus on the positive consequences of a given activity, set goals, and use emotion regulation. Focusing on positive consequences, focusing on negative consequences (of not performing the activity), thinking of the near finish, and emotion regulation increased perceived self‐regulatory success across demands, whereas distracting oneself from the aversive activity decreased it. None of these strategies, however, accounted for the beneficial effects of trait self‐control on perceived self‐regulatory success. Hence, trait self‐control and strategy use appear to represent separate routes to good self‐regulation. By considering trait‐ and process‐approaches these findings promote a more comprehensive understanding of self‐regulatory success and failure during people's daily attempts to regulate their persistence. © 2018 European Association of Personality Psychology     

Metacognitive myopia and the overutilization of misleading advice

Previous research on advice taking has explained the failure to exploit collective wisdom in terms of the egocentric underweighting of advice provided by independent others. The present research is concerned with an opposite and more radical source of irrational advice taking, namely, the failure to critically assess the validity of advice due to metacognitive myopia. Participants could use the advice of one or two experts when estimating health risks. They read sketches of the study samples that experts had drawn to estimate conditional probabilities (e.g., of HIV‐given drug addiction). Whether samples were valid or seriously biased, subsequent judgments were strongly affected by any advice (Experiment 1). Uncritical reliance on any advice persisted when participants were sensitized to the contrast of valid and invalid advice in a repeated measures design (Experiment 2), when participants themselves believed advice not to be valid (Experiment 3), and even after full debriefing about invalid advice (Experiment 4). Lay advice exerted a similar influence as expert advice (Experiment 5). Although these provocative results are independent of numeracy and consensus (Experiment 6), they highlight the impact of metacognitive myopia as an impediment of social rationality.     

临床麻醉中常用中效肌肉松弛剂的比较

为了更准确在临床麻醉过程中使用中效肌肉松弛剂,用比较治疗学的理念及方法对目前国内报道的中效肌肉松弛剂阿曲库铵、顺式阿曲库铵、维库溴铵、罗库溴铵的应用方法进行比较和分析。结果发现：插管起效时间罗库溴铵最短,临床时效顺式阿曲库铵最长,阿曲库铵有组胺释放的作用,阿曲库铵和顺式阿曲库铵药物代谢主要是霍夫曼消除。比较治疗学方法有助于临床麻醉肌松剂的抉择。     

Using selection,optimization, and compensation to reduce job/family stressors: effective when it matters

Previous research has demonstrated that the use of general behaviors specified by a life-management strategy entitled Selection, Optimization, and Compensation (SOC) reduces, if only to a small extent, the perceived amounts of the main antecedents (i.e., job/family stressors) of work-family conflict. The results of the current study demonstrate that several variables that impact the amount of resources demanded of, or resources available to, an individual (e.g., supervisor support) moderate the relationship between SOC behaviors and job/family stressors. Specifically, SOC strategies are more effective than previously thought at reducing job/family stressors for precisely those individuals in the most demanding situations.     

肺保护策略机械通气的再评价

通常认为急性肺损伤/急性呼吸窘迫综合征(ALI/ARDS)患者应用肺保护策略机械通气可降低病死率,主要由于潮气量的降低。对已发表的随机对照研究再次分析,发现平台压与患者病死率明显相关。平台压低于30cmH2O时,潮气量可以在一定范围内增加,不影响患者预后。但选择小潮气量可能对病人有害。随机对照研究在试验设计、统计学分析、病人同质性等方面依然存在很多问题。从现有资料看,潮气量和平台压都很重要。
