Why are Extraverts more Satisfied? Personality,Social Experiences,and Subjective Well‐being in College

It is widely appreciated that extraversion is associated with greater subjective well‐being. What is not yet clear is what mechanisms relate the two. In two longitudinal studies, we explored whether extraversion is prospectively associated with higher levels of satisfaction during college through influencing college social experiences using longitudinal cross‐lagged mediation models. In both studies, students' extraversion at the beginning of college predicted their subjective well‐being 4 years later. In both studies, extraversion at the beginning of college predicted a variety of self‐reported and peer‐reported social experiences (e.g. feelings of belonging and size of social network). We tested whether qualitative or quantitative aspects of social experiences explained the association between extraversion and subjective well‐being. In the first study, neither type of social experience explained the effect of extraversion on satisfaction. Only qualitative social experiences in the second study were instrumental in explaining this effect. The results suggest that extraversion's ability to create better social experiences can play a role in extraverts' greater subjective well‐being, but these experiences are not the only reason extraverts are happier and more satisfied.

Internet Safety and the Silver Surfer: The Relationship Between Gist Reasoning and Adults' Risky Online Behavior

Currently, fewer older adults are online compared with younger generations. However, with many new initiatives aiming to significantly increase the number of older internet users, they will increasingly be exposed to potential victimisation from internet fraud, a fundamental issue affecting all adult internet users. Despite this, little research has examined online risk‐taking across the adult lifespan or adults' reasoning about risky online behaviors. Using fuzzy trace theory, we investigated adults' online risk‐taking behavior and intentions, and whether these behaviors were related to different ways of reasoning about risk, namely, gist reasoning (using qualitative, intuitive knowledge) and verbatim reasoning (using quantitative, specific knowledge). Participants (326 adults, 18–79 years old, M_age = 49.54 years) reported their past risk‐taking behavior, future online risk intentions, gist and verbatim reasoning about online risk, sensation seeking, and time spent online. Age was negatively correlated with past risk‐taking, time online, future risk intentions, and sensation seeking. However, time spent online was positively related to future risk intentions, suggesting that spending more time using the internet could lead individuals to take more risks. Increased verbatim reasoning predicted increased intentions to take online risks, while gist reasoning predicted reduced intentions to take risks online. Our findings extend online risk research applying fuzzy trace theory to adolescents and young adults and suggest that online safety training incorporating gist‐based reasoning strategies could benefit all adults and, in particular, older generations.

Development of a Behavioral Activation–Based Intervention for Cigarette-Smoking Young Adults

Quitting smoking during young adulthood can substantially reduce tobacco-related morbidity and mortality later in life. Depressive symptomatology is prevalent among smokers and increases risk for poor smoking cessation outcomes. However, few integrated behavioral interventions simultaneously target smoking and depressive symptoms and rarely have young smokers been included in the development of these interventions. In this paper we describe an 8-session behavioral activation–based treatment for smoking (BATS; MacPherson et al., 2010) adapted for youth. We conducted a series of focus groups with young adult smokers with depressive symptoms in order to modify treatment manuals to be developmentally appropriate. Subsequently, we completed a small pilot group (n = 5) of the intervention to provide preliminary data on feasibility, acceptability, and outcomes. We provide a case series of the participants in order to provide clinical illustrations of how the modified BATS treatment was implemented among young adults. Most pilot study participants exhibited smoking abstinence and smoking reductions at the end of treatment, as well as improvement in depressive symptoms and maintenance of levels of activation and environmental reward. Participants provided positive qualitative constructive feedback regarding the intervention.     

流调中心抑郁量表在老年人群中的因素结构

本研究使用4903名老年人组成的全国样本,系统地检验了流调中心抑郁量表的因素结构。结果表明,Radloff的四因素结构、Guarnaccia等和Yen等的三因素结构对当前样本数据的拟合较好,但信度分析和相关分析显示积极情绪因素降低了总量表信度,并且与其他因素之间不支持共同的高阶因素（抑郁）,基于此,在使用量表合成总分的背景下,4个积极情绪项目不适合包含在CES-D量表中。随后,本研究检验了剔除积极情绪项目后量表各因素结构的拟合情况,发现积极情绪因素对量表因素结构的拟合水平贡献不大。结合拟合指数和Radloff对量表的界定,16项目的三因素结构最适合于我国老年人群,并且,这一因素结构在老年人群中具有跨性别的恒等性。     

Regional differences in brain volume predict the acquisition of skill in a complex real-time strategy videogame

Previous studies have found that differences in brain volume among older adults predict performance in laboratory tasks of executive control, memory, and motor learning. In the present study we asked whether regional differences in brain volume as assessed by the application of a voxel-based morphometry technique on high resolution MRI would also be useful in predicting the acquisition of skill in complex tasks, such as strategy-based video games. Twenty older adults were trained for over 20 h to play Rise of Nations, a complex real-time strategy game. These adults showed substantial improvements over the training period in game performance. MRI scans obtained prior to training revealed that the volume of a number of brain regions, which have been previously associated with subsets of the trained skills, predicted a substantial amount of variance in learning on the complex game. Thus, regional differences in brain volume can predict learning in complex tasks that entail the use of a variety of perceptual, cognitive and motor processes.     

Trajectory of risky decision making for potential gains and losses from ages 5 to 85

The ability to make advantageous decisions in the face of uncertainty is an essential human skill, yet the development of such abilities over the lifespan is still not well understood. In the current study, from childhood through older adulthood, we tracked the developmental trajectory of risk taking for gains and losses, and expected value (EV) sensitivity in risky choices. In the gain domain, risk‐taking decreased consistently across the lifespan. In the loss domain, risk‐taking was relatively constant across ages, a result we attribute to the pervasiveness of loss aversion. EV sensitivity showed an inverted‐U‐shaped function, increasing from childhood to adulthood but then decreasing for the elderly, which occurred for both risky gains and risky losses. This finding is consistent with neuropsychological and neuroanatomical evidence concerning the role of the frontal lobe in decision making, which is relatively late to develop during childhood but may degrade earlier in the later years.

The Stationary-Gaze Task Should Not Be Systematically Used as the Control Task in Studies of Postural Control

In studies of postural control, a control task is often used to understand significant effects obtained with experimental manipulations. This task should be the easiest task and (therefore) engage the lowest behavioral variability and cognitive workload. Since 1983, the stationary-gaze task is considered as the most relevant control task. Instead, the authors expected that free looking at small targets (white paper or images; visual angle: 12°) could be an easier task. To verify this assumption, 16 young individuals performed stationary-gaze, white-panel, and free-viewing 12° tasks in steady and relaxed stances. The stationary-gaze task led to significantly higher cognitive workload (mean score in the National Aeronotics and Space Administration Task Load Index questionnaire), higher interindividual body (head, neck, and lower back) linear variability, and higher interindividual body angular variability—not systematically yet—than both other tasks. There was more cognitive workload in steady than relaxed stances. The authors also tested if a free-viewing 24° task could lead to greater angular displacement, and hence greater body sway, than could the other tasks in relaxed stance. Unexpectedly, the participants mostly moved their eyes and not their body in this task. In the discussion, the authors explain why the stationary-gaze task may not be an ideal control task and how to choose this neutral task.     

Assessing motor proficiency in young adults: The Bruininks Oseretsky Test-2 Short Form and the McCarron Assessment of Neuromuscular Development

Currently, only two motor tests have norms extending into young adulthood – the McCarron Assessment of Neuromuscular Development (MAND, McCarron 1997) and the Bruininks Oseretsky Test of Motor Proficiency-2 (BOT-2, Bruininks & Bruininks, 2005). Research into the motor difficulties in early adulthood and health outcomes has been impeded because there is no agreed gold standard motor test for this group. The purposes of this study were to compare the discrimination accuracy, classification agreement, and predictive values, and gender distribution and prevalence of each test in identifying motor impairment (MI) in relation to DSM-V diagnostic criteria for DCD. Ninety-one young, healthy adults (M = 21.4 years, SD = 3.3) were recruited. Those classified as MI by each test scored at one standard deviation or more below the overall mean standard score. Small, statistically significant correlations were found between the MAND and BOT-2 SF tests for score rank (r = 0.370, p = 0.01) and standard score values (r = 0.404; p = 0.01). The overall decision agreement for non-MI cases was relatively high at 85% but very low for MI cases (4.4%). Unexpectedly, gender was balanced in MI cases. BOT-2 SF identified twice as many MI cases than MAND (13.2% vs 6.6%), yet overall comparative test specificity was high (89%). Predictive values for MAND, compared against BOT-2 SF as the standard, indicated broad independence between these tests and overall, the decision statistics indicated that the two tests identified different adult cohorts with MI. Objective classification of adult motor proficiency using a gold standard assessment tool including complex and ecologically valid tasks is still elusive.     

Functional Synergy Between Postural and Visual Behaviors When Performing a Difficult Precise Visual Task in Upright Stance

Previous works usually report greater postural stability in precise visual tasks (e.g., gaze‐shift tasks) than in stationary‐gaze tasks. However, existing cognitive models do not fully support these results as they assume that performing an attention‐demanding task while standing would alter postural stability because of the competition of attention between the tasks. Contrary to these cognitive models, attentional resources may increase to create a synergy between visual and postural brain processes to perform precise oculomotor behaviors. To test this hypothesis, we investigated a difficult searching task and a control free‐viewing task. The precise visual task required the 16 young participants to find a target in densely furnished images. The free‐viewing task consisted of looking at similar images without searching anything. As expected, the participants exhibited significantly lower body displacements (linear, angular) and a significantly higher cognitive workload in the precise visual task than in the free‐viewing task. Most important, our exploration showed functional synergies between visual and postural processes in the searching task, that is, significant negative relationships showing lower head and neck displacements to reach more expended zones of fixation. These functional synergies seemed to involve a greater attentional demand because they were not significant anymore when the cognitive workload was controlled (partial correlations). In the free‐viewing task, only significant positive relationships were found and they did not involve any change in cognitive workload. An alternative cognitive model and its potential subtended neuroscientific circuit are proposed to explain the supposedly cognitively grounded functional nature of vision–posture synergies in precise visual tasks.
