A social-cognitive framework for understanding serious lies: Activation-decision-construction-action theory

Little is known about the cognition of deception (Gombos, 2006). We propose a cognitive account of serious lying (i.e., deception involving high stakes) in response to a solicitation of a truth: Activation-Decision-Construction-Action Theory (ADCAT). Built on the Activation-Decision-Construction Model of answering questions deceptively (Walczyk, Roper, Seeman, & Humphrey, 2003), the theory elaborates on the roles of executive processes, theory of mind, emotions, motivation, specifies cognitive processing thoroughly, and considers the rehearsal of lies. ADCAT's four processing components are (a) activation of the truth, the (b) decision whether and how to alter deceptively the information shared, (c) construction of a deception, and (d) action [acting sincere while delivering a lie]. Core constructs are “theory of mind” and “cognitive resources”. Specifically, throughout serious deception, individuals are inferring the current or potential mental states of targets and taking steps to minimize the allocation of cognitive resources during delivery to appear honest and lie well.     

The association between team‐level social capital and individual‐level work engagement: Differences between subtypes of social capital and the impact of intra‐team agreement

The study explored the association between team‐level social capital and individual‐level work engagement. Questionnaire data were collected from six companies in the dairy industry. Seven hundred seventy‐two participants divided into 65 teams were included. In confirmatory factor analyses, we found a superior model fit to a four dimensional model of social capital: bonding social capital, bridging social capital and two types of linking social capital. The results showed a positive association between all subtypes of social capital at the team level and work engagement at the individual level. However, this association only remained significant for linking social capital in relation the workplace as a whole when we adjusted for psychosocial working conditions. The level of intra‐team agreement in social capital score did not moderate the association between social capital and work engagement. In conclusion, the results provide further support for previous findings suggesting a positive association between social capital and work engagement. They add to the existing knowledge by suggesting that linking social capital in relation to the workplace is the most important explanatory variable for work engagement, thus emphasizing the need to distinguish between subtypes of social capital in research and practice.     

Natural Disasters in Indonesia: Relationships Among Posttraumatic Stress,Resource Loss,Depression, Social Support,and Posttraumatic Growth

ABSTRACT

Indonesia is at significant risk for catastrophic natural disasters, including earthquakes, volcanic eruptions, and tsunamis. Few studies have examined psychological functioning following disaster exposure in Indonesia, the fourth most populous country in the world. This study assesses variables associated with posttraumatic stress and posttraumatic growth following a devastating earthquake in Central Java that ranks as one of the costliest in Indonesia. The participants were 85 men and women living in rural farming villages. Almost all (95%) experienced major home damage or total home destruction. Posttraumatic stress symptoms were associated with resource loss, depression, and concerns about future earthquakes. Participants reported moderate posttraumatic growth. Posttraumatic growth was associated with energy resource loss and social support. The findings support conservation of resources stress theory. The implications of the findings for intervention and recovery programs are discussed.     

资源多寡对大学生择偶线索偏好的影响

本研究采用分配择偶币的范式考察资源多寡对大学生择偶线索偏好的影响。结果发现：1）择偶资源多寡影响大学生的择偶线索偏好,低资源条件下人们更看重忠贞、健康等“必需品”（necessities）,高资源条件下则会增加对创造力等“奢侈品”（luxuries）的考虑。2）择偶线索偏好存在性别差异,当自身资源较少时,女性比男性更看重长期伴侣的社会经济地位,而男性比女性更看重伴侣的忠贞;当自身具备高资源时,性别差异不显著。本研究发现择偶线索中的“奢侈品”和国外研究结果类似,而“必需品”和国外研究差异较大。研究结果表明,择偶线索偏好可能受到进化和社会文化因素的共同影响。

Attention is required for maintenance of feature binding in visual working memory

Working memory and attention are intimately connected. However, understanding the relationship between the two is challenging. Currently, there is an important controversy about whether objects in working memory are maintained automatically or require resources that are also deployed for visual or auditory attention. Here we investigated the effects of loading attention resources on precision of visual working memory, specifically on correct maintenance of feature-bound objects, using a dual-task paradigm. Participants were presented with a memory array and were asked to remember either direction of motion of random dot kinematograms of different colour, or orientation of coloured bars. During the maintenance period, they performed a secondary visual or auditory task, with varying levels of load. Following a retention period, they adjusted a coloured probe to match either the motion direction or orientation of stimuli with the same colour in the memory array. This allowed us to examine the effects of an attention-demanding task performed during maintenance on precision of recall on the concurrent working memory task. Systematic increase in attention load during maintenance resulted in a significant decrease in overall working memory performance. Changes in overall performance were specifically accompanied by an increase in feature misbinding errors: erroneous reporting of nontarget motion or orientation. Thus in trials where attention resources were taxed, participants were more likely to respond with nontarget values rather than simply making random responses. Our findings suggest that resources used during attention-demanding visual or auditory tasks also contribute to maintaining feature-bound representations in visual working memory—but not necessarily other aspects of working memory.     

Are trait self-control and self-control resources mediators of relations between executive functions and health behaviors?

This study investigated associations between executive functions (i.e., inhibition, working memory, cognitive flexibility) and individual differences in self-control and health behaviors. We examined whether executive functions predict physical activity, sedentary activity, and healthy and unhealthy diets, and whether trait self-control and self-control resources mediate these associations. Three hundred and eighty-five participants completed a questionnaire assessing trait self-control and self-control resources, physical activity, sedentary activity, and healthy and unhealthy diets. They also performed three randomly ordered cognitive tasks, a stop-signal task (i.e., inhibition), a letter memory task (i.e., updating), and a number-letter task (i.e., switching). Structural equation modeling revealed that self-control resources predicted positively physical activity (R² = 0.08), negatively sedentary activity (R² = 0.03) and positively healthy diet (R² = 10). Moreover, trait self-control predicted positively healthy diet (R² = 0.10) and negatively unhealthy diet (R² = 0.19). Moreover, analyses revealed that switching significantly predicted self-control resources, and highlighted three totally mediated relations between this executive function and physical activity, sedentary activity and healthy diet. However, no evidence was found supporting associations between inhibition and updating, and health behaviors, or relations mediated by self-control for these executive functions. The findings suggest the importance of trait self-control and self-control resources for health behavior adoption and pave the way for studies exploring the role of the executive functions in an affective context.

Gender Differences in Problem Drinking and Depression: Different “Vulnerabilities?”

This study examines the relationship between stressors and resources and the functioning of a sample of 515 men and women who had a drinking problem. At a one-year follow-up, both women and men had improved on three functioning measures: alcohol consumption, days intoxicated, and depression. There were no gender differences at Time 2 on alcohol consumption, but men had more days intoxicated and women had more symptoms of depression. The impact of stressors and resources varied by life domain, functioning criterion, and gender. Although the predictors varied, the amount of variance in depression accounted for was the same for women and men. The most striking gender difference was the stronger impact of friendships for women on all aspects of functioning. This study provides support for reconsideration of the stress vulnerability of women and men.
