生命意义的缺失与追寻

生命意义(Meaning in life)指人们对自己生命中的目的、目标的认识和追求,主要包括意义存在(Presence of Meaning)和意义追求(Search for Meaning)两个维度。生命意义缺失(Absence of Meaning)指个体缺乏生活的目标、对自身存在价值和意义感的感知。意义缺失的体验一方面会带来焦虑、抑郁等消极影响,另一方面将激发起个体强烈的重构意义的动机,引导人们进行意义追求。未来研究应增加对生命意义的获取和提升、意义缺失的原因、含义与结构、意义追求的动机和效果的研究。     

Attentional biases to threat in social anxiety disorder: time to focus our attention elsewhere?

Background: Cognitive models propose that attentional biases to threat contribute to the maintenance of social anxiety disorder (SAD). However, the specific characteristics of such biases are still object to debate.

Objectives: The current study aimed to disentangle effects of trait and state social anxiety on attention allocation towards social stimuli.

Methods: Participants with SAD (n?=?67) and healthy controls (n?=?62) completed three visual search tasks while their eye movements were recorded. Half of the participants in each group were randomly assigned to a state anxiety induction.

Results: Contrary to our predictions, neither trait nor state social anxiety was associated with a facilitated attention to or a delayed disengagement from threat. However, participants with SAD did show reduced fixation durations for threatening stimuli, indicating an avoidance of threat. Induction of state anxiety led to an increased distractibility by threat.

Conclusions: We suggest that attention allocation in SAD is characterized by an avoidant rather than a vigilant attentional bias. Accordingly, our results contradict previous results that associate SAD with facilitated attention to threat and existing approaches to modify attentional biases, that aim to decrease attention towards threatening stimuli.     

The relationship between visual search and categorization of own- and other-age faces

Young adult participants are faster to detect young adult faces in crowds of infant and child faces than vice versa. These findings have been interpreted as evidence for more efficient attentional capture by own-age than other-age faces, but could alternatively reflect faster rejection of other-age than own-age distractors, consistent with the previously reported other-age categorization advantage: faster categorization of other-age than own-age faces. Participants searched for own-age faces in other-age backgrounds or vice versa. Extending the finding to different other-age groups, young adult participants were faster to detect young adult faces in both early adolescent (Experiment 1) and older adult backgrounds (Experiment 2). To investigate whether the own-age detection advantage could be explained by faster categorization and rejection of other-age background faces, participants in experiments 3 and 4 also completed an age categorization task. Relatively faster categorization of other-age faces was related to relatively faster search through other-age backgrounds on target absent trials but not target present trials. These results confirm that other-age faces are more quickly categorized and searched through and that categorization and search processes are related; however, this correlational approach could not confirm or reject the contribution of background face processing to the own-age detection advantage.     

The longitudinal association between internalizing symptoms and academic achievement among immigrant and non‐immigrant children in Norway

The aim of this study was to explore the longitudinal relation between internalizing symptoms and academic achievement, as two processes of children and youth development, among children in Norway, and whether having an immigrant background moderated this association. Data collected from 4,458 students in Norway in four waves over three years were analyzed with multi‐group latent growth curve modeling (LGM ). Results showed that internalizing symptoms level remained unchanged over time both for immigrant and non‐immigrant children, while levels of academic achievement increased only for children of immigrants with both parents born outside of Norway. Further analyses supported a reciprocal relation between internalizing symptoms and academic achievement and revealed that the initial level of academic achievement predicted the rate of change in internalizing symptoms over time, but not vice versa. Moreover, immigrant background did not moderate the associations in the model, however, children of immigrants with both parents born abroad initially had lower levels of academic achievement, but showed an increase in academic achievement, compared to their non‐immigrant peers as well as to peers with one native‐born parent after controlling for gender and their grade at the first observation. The implications for policy and practice were discussed.     

Investigating Individual Differences in Toddler Search with Mixture Models

Children's performance on cognitive tasks is often described in categorical terms in that a child is described as either passing or failing a test, or knowing or not knowing some concept. We used binomial mixture models to determine whether individual children could be classified as passing or failing two search tasks, the DeLoache model room task and the Berthier et al. door task. The data support categorical classification of the children and suggest that the increase in average proportion correct with age is the result of an increasing proportion of children who can solve the tasks. Performance on the two tasks was concordant, and improving performance could be due to advances in a single psychological ability, such as cognitive control.

Job search self-efficacy: Reconceptualizing the construct and its measurement

Job search self-efficacy (JSSE) is one of the most studied variables in the job search literature and an important component of the theory of planned behavior and self-regulation theory which have both been used to explain the job search process. However, even though JSSE has been a part of job search research for thirty years, the measurement of JSSE has varied from study to study. This questions both the validity of the measures used and the findings from each study that used a different measure. In this paper, we propose and test a two dimensional measure of JSSE that corresponds to job search behavior (JSSE-B) and job search outcomes (JSSE-O). The results of a longitudinal study of employed and unemployed job seekers support a two-factor model corresponding to the two dimensions of JSSE. We also found differential relationships between each dimension of JSSE and several antecedents and consequences. Among the antecedents, environmental exploration and self-exploration were stronger predictors of JSSE-B while career planning was a stronger predictor of JSSE-O. In terms of consequences, JSSE-B was a stronger predictor of job search intention and behavior while JSSE-O was a stronger predictor of the number of job offers received. These findings provide support for two dimensions of JSSE and have important implications for job search research and practice.     

Redundant food searches by capuchin monkeys (Cebus apella): a failure of metacognition?

This study investigated capuchin monkeys' understanding of their own visual search behavior as a means to gather information. Five monkeys were presented with three tubes that could be visually searched to determine the location of a bait. The bait's visibility was experimentally manipulated, and the monkeys' spontaneous visual searches before tube selection were analyzed. In Experiment 1, three monkeys selected the baited tube significantly above chance; however, the monkeys also searched transparent tubes. In Experiment 2, a bent tube in which food was never visible was introduced. When the bent tube was baited, the monkeys failed to deduce the bait location and responded randomly. They also continued to look into the bent tube despite not gaining any pertinent information from it. The capuchin monkeys' behavior contrasts with the efficient employment of visual search behavior reported in humans, apes and macaques. This difference is consistent with species-related variations in metacognitive abilities, although other explanations are also possible.     

登机牌信息要素及其布局研究

随着民航行业的快速发展,飞机登机牌的使用率越来越高,而不同航空公司所采用的登机牌在信息内容和布局设计等方面均缺乏相关的设计规范,因此有必要从可用性角度对登机牌进行系统的研究.首先,采用KANO问卷法对登机牌上的文字信息要素进行研究,并基于研究结果设计出新登机牌;然后,从搜索绩效和主观偏好两个方面对新旧登机牌进行比较评价研究.结果显示：①登机牌上必须呈现的信息主要包括登机时间、登机口、航班号、座位号、姓名、日期和目的地七项必要信息,以及可提高旅客使用体验的预计飞行时间信息,但登机牌上不能呈现旅客身份证号码等个人隐私信息;②基于信息要素研究结果重新布局设计的新登机牌在搜索绩效和主观偏好方面均显著优于现有登机牌.本研究结果可为将来的登机牌设计提供科学依据.
