Intertrial temporal contextual cuing: association across successive visual search trials guides spatial attention

Contextual cuing refers to the facilitation of performance in visual search due to the repetition of the same displays. Whereas previous studies have focused on contextual cuing within single-search trials, this study tested whether 1 trial facilitates visual search of the next trial. Participants searched for a T among Ls. In the training phase, the spatial layout on trial N=1 was predictive of the target location on trial N. In the testing phase, the predictive value was removed. Results revealed an intertrial temporal contextual cuing effect: Search speed became progressively shorter in the training phase, but it significantly lengthened during testing. The authors conclude that the visual system is capable of retaining spatial contextual memory established earlier to facilitate perception.     

What is learned in spatial contextual cuing--configuration or individual locations?

With the use of spatial contextual cuing, we tested whether subjects learned to associate target locations with overall configurations of distractors or with individual locations of distractors. In Experiment 1, subjects were trained on 36 visual search displays that contained 36 sets of distractor locations and 18 target locations. Each target location was paired with two sets of distractor locations on separate trials. After training, the subjects showed perfect transfer to recombined displays, which were created by combining half of one trained distractor set with half of another trained distractor set. This result suggests that individual distractor locations were sufficient to cue the target location. In Experiment 2, the subjects showed good transfer from trained displays to rescaled, displaced, and perceptually regrouped displays, suggesting that the relative locations among items were also learned. Thus, both individual target-distractor associations and configural associations are learned in contextual cuing.     

由上博简《诗说》的体例论其定名与作者

上博简《诗说》中出现的六次“孔子日”以及以“曷”字形式出现的孔子言论,实际上都是《诗说》作者引述孔子的言论来支持自己的《诗》学观点。由这一体例可以肯定,《诗说》的作者不是孔子;而应该是孔子的门徒或再传弟子。据有关材料判断,这个门徒最有可能是子夏。因此,《上海博物馆藏战国楚竹书》中所定名的《孔子诗论》,若更名为《诗说》更符合竹简内容,也切合周秦古书的定名规律。     

Implicit,long-term spatial contextual memory

Learning and memory of novel spatial configurations aids behaviors such as visual search through an implicit process called contextual cuing (M. M. Chun & Y. Jiang, 1998). The present study provides rigorous tests of the implicit nature ofcontextual cuing. Experiment 1 used a recognition test that closely matched the learning task, confirming that memory traces of predictive spatial context were not accessible to conscious retrieval. Experiment 2 gave explicit instructions to encode visual context during learning, but learning was not improved and conscious memory remained undetectable. Experiment 3 illustrates that memory traces for spatial context may persist for at least 1 week, suggesting along-term component of contextual cuing. These experiments indicate that the learning and memory of spatial context in the contextual cuing task are indeed implicit. The results have implications for understanding the neural substrate of spatial contextual learning, which may depend on an intact medial temporal lobe system that includes the hippocampus (Mi. M. Chun & E. A. Phelps, 1999).     

Regional grey matter volume in the posterior cingulate cortex predicts positive risk-taking: A moderation model

Positive risk-taking is a crucial element of individual creativity and social development. However, little is known regarding the relation between individual neural differences and positive risk-taking. In addition, critical thinking (CT) and gender have been proven to be two important individual-specific factors associated with risk-taking behaviour, and different levels of CT and gender may have diverse effects on the relationship between brain structure and positive risk-taking. The present study examined the relationship between positive risk-taking and regional grey matter volume (rGMV) in 292 healthy participants. The results showed that positive risk-taking was significantly positively associated with the rGMV of the posterior cingulate cortex (PCC). In addition, this study investigated individual differences in critical thinking and found that it moderated the relationship between rGMV and positive risk-taking. Individuals with lower CT had a stronger association between rGMV and positive risk-taking. Further analysis showed that for males, a greater rGMV was significantly linked to higher positive risk-taking tendency. These findings suggest that PCC evaluates risk and serves as a behavioural adaptation hub for positive risk-taking. This study thereby contributes to the literature on individual differences in brain structure and risk-taking by elucidating the moderating effects of CT and gender in healthy adults.     

The potential mediating role of anxiety sensitivity in the impact of mindfulness training on anxiety and depression severity and impairment: A randomized controlled trial

The benefits of mindfulness-based interventions to alleviate anxiety and depression have been supported by many studies. Given the effectiveness of mindfulness-based interventions on anxiety and depression, the underlying mechanisms need to be explored. Using a randomized waitlist-controlled design, this study investigated whether anxiety sensitivity was a potential mechanism for the impact of mindfulness training on anxiety and depression. Participants with high psychological distress were randomly assigned to an eight-week mindfulness intervention (N = 35) or a wait-list control group (N = 34). Before and after the intervention or corresponding waitlist period, participants completed measures of anxiety and depression severity and impairment and anxiety sensitivity. Separate mixed ANOVA demonstrated significant group (intervention vs. control group) × time (pre- vs. post-test) interactions for anxiety sensitivity and overall anxiety severity and impairment and marginally significant interaction for overall depression severity and impairment. Moreover, simple mediation models showed that reductions of anxiety sensitivity from pre- to post-test mediated the impact of mindfulness training on changes in anxiety and depression severity and impairment. The findings suggest that anxiety sensitivity is a potential mechanism underlying the effect of mindfulness training on anxiety and depression, which provides a new perspective for the study of processes of change of mindfulness-based interventions.     

Career proactivity: A bibliometric literature review and a future research agenda

Individuals often need to be proactive in order to successfully navigate their career development journeys. To what extent one is vocationally proactive has critical implications for his or her attitudes, behaviors, and other outcomes in career and work-related settings. However, research in career proactivity has been accumulating from divergent perspectives, resulting in a substantially fragmented literature that has not been comprehensively, objectively synthesized to guide the field to move forward. To advance the domain of career proactivity, this paper synthesizes theoretical and empirical literatures using two major bibliometric analyses. We first analyze the intellectual basis of the career proactivity literature by performing document citation analysis. We then review the developmental trends of main conceptual themes in career proactivity literature using a temporal co-word analysis. Informed by these bibliometric findings, we propose a roadmap for future research highlighting the need to clear up concepts, account for context, develop new meso-level theories, and bridge the domains of organizational behavior and vocational development.     

How does workplace ostracism hurt employee creativity? Thriving at work as a mediator and organization-based self-esteem as a moderator

Drawing on the socially embedded model of thriving and conservation of resources theory, we explore the negative effect of workplace ostracism on employee thriving. We model organization-based self-esteem (OBSE) as a moderator and extend our examination to the downstream implications of thriving for employee creativity. Using a scenario-based experiment (Study 1) with 387 working adults, we find that workplace ostracism is more likely to prevent workers with higher levels of OBSE from thriving at work. This finding is verified in Study 2, in which we use multiwave, multisource data collected from 207 employees and their supervisors to test the proposed model. The results further show that for employees with higher levels of OBSE, thriving at work is more likely to mediate the relationship between workplace ostracism and employee creativity. These findings provide important practical implications for fostering employee thriving and promoting creativity in the workplace by managing workplace ostracism.     

Examining college students' food security coping strategies and experiences during the COVID-19 pandemic

College students' food situations may have been disrupted by the COVID-19 pandemic, which could have affected their health and well-being. However, little is known about how the pandemic impacted students' food experiences and how students coped with food-related disruptions, particularly from the student's own perspective. This study reviews data from 571 undergraduates who attended public colleges during Fall 2021 and Spring 2022 and wrote a narrative about the pandemic's impact on their food experiences. Most students indicated they experienced a wide range of food difficulties and adapted new food practices. Despite these challenges, students emphasized proactive coping strategies and positive pandemic outcomes rather than difficulties and negative outcomes. These findings have implications for students' long-term health and well-being.
