Characteristics of ADHD Related to Executive Function: Differential Predictions for Creativity-Related Traits

Although the relationship between creativity and ADHD is uncertain, recent studies examining how dimensionally assessed characteristics of ADHD relate to creativity and divergent thinking in adults suggest an occasional positive, linear relationship between the constructs. However, the executive functions proposed to underlie characteristics of ADHD have not been examined in relation to creativity. This study was conducted to determine how different characteristics of ADHD related to executive functioning (as assessed by the Brown ADD Scales) predict different components of figural divergent thinking, intellectual risk-taking, and creative self-efficacy. Undergraduate engineering students (N = 60) completed the Brown ADD Scales, a figural divergent thinking task, and self-report measures of intellectual risk-taking and creative self-efficacy. A series of multivariate regression models demonstrated that several components of divergent thinking (i.e., fluency, originality, and resistance to closure) were predicted by different characteristics of ADHD. Although fluency was predicted by affect only and originality was predicted by activation only, resistance to closure was predicted by activation, effort, and attention. Additionally, intellectual risk-taking was predicted by memory, effort, and activation, whereas creative self-efficacy was predicted by effort. The implications of these results relating to the relationship between ADHD and creativity, as well as for engineering undergraduate education are discussed.     

Are choices based on conditional or conjunctive probabilities in a sequential risk-taking task?

In this study, we examined participants' choice behavior in a sequential risk-taking task. We were especially interested in the extent to which participants focus on the immediate next choice or consider the entire choice sequence. To do so, we inspected whether decisions were either based on conditional probabilities (e.g., being successful on the immediate next trial) or on conjunctive probabilities (of being successful several times in a row). The results of five experiments with a simplified nine-card Columbia Card Task and a CPT-model analysis show that participants' choice behavior can be described best by a mixture of the two probability types. Specifically, for their first choice, the participants relied on conditional probabilities, whereas subsequent choices were based on conjunctive probabilities. This strategy occurred across different start conditions in which more or less cards were already presented face up. Consequently, the proportion of risky choices was substantially higher when participants started from a state with some cards facing up, compared with when they arrived at that state starting from the very beginning. The results, alternative accounts, and implications are discussed.     

Take a risk or proceed with caution: Prevention motivation moderates responses to near-loss events

A persistently pressing issue identified in the decision-making literature is that people not only fail to recognize the risks entailed in a near-loss event but also subsequently engage in further risk-taking. We contend in this paper that prevention motivation critically regulates decision-makers' responses to a near-loss. Across three studies, we found that high prevention-focused individuals perceive greater risks in a near-loss event and are subsequently less likely to take risks, compared with low prevention-focused individuals. This finding highlights the significance of applying a motivational perspective to studying decision-making and risk.     

Risk-Taking by Young People in Late Adolescence Increases When They Perceive the Possibility of Their Peer “Observing Someday”

This experimental study on risk-taking by young people in their late adolescence was carried out from the perspective of peer effect. A gambling task was administered to 42 young people under the following experiment conditions: with or without the possibility that the experiment results would be disclosed at some time to their peers and information about their peers being more or less risk-oriented. The results showed that when it was suggested that the experiment results would be disclosed in some time and when the peer was perceived as more risk-oriented, there was a peer effect. However, when the peer was perceived as less risk-oriented, no peer effect occurred. The findings of this study confirmed that, while there is some room for further testing, when it was suggested that the experiment result might be disclosed to the peer, even under a condition in which only a single participant was involved, there was a peer effect, unlike in previous studies.     

领导者对员工主动行为的心理与行为反应

员工主动行为因有利于个人和组织的长远发展而受到学界和业界的广泛关注。以往的研究主要关注主动行为对员工本人的人际内影响,而较少考虑对领导者的人际间影响;同时,考虑到员工在领导过程中扮演的重要角色,对员工的主动行为如何影响领导的心理与行为反应做理论性整理将极大丰富对员工主动行为的认识。学界基于归因理论、内隐追随理论、自我-他人评价一致性理论等对上述自下而上的影响过程进行了初步探索,发现领导者对员工主动行为的态度评价和行为反应受到多重边界条件的影响。未来研究可具体化员工主动行为所诱发的领导者心理与行为反应,探索员工主动行为与领导方式的循环关系,以及深挖主动行为与绩效评价之间的内在机理。     

群体关系与问责对信息共享意愿及谈判行为的影响研究

本研究就国人的群体关系与问责对谈判者行为及信息共享意愿进行考察,试图探讨文化对谈判者的影响。通过对128名在校大学生的模拟谈判实验,发现谈判者在群内谈判比在群际谈判时有更高的信息共享意愿和更少的强硬行为,群体关系和问责对信息共享意愿及主观利益冲突有交互效应。具体而言,高度问责时,谈判者在群内谈判比群际谈判时有更多的信息共享意愿;低度问责时,谈判者在群内谈判比群际谈判时有更少的主观利益冲突。     

Counterproductive Behaviors and Psychological Well-being: The Moderating Effect of Task Interdependence

Purpose  The purpose of this study was to investigate the relationship between counterproductive behaviors (CPBs) and psychological well-being in a teamwork setting. Moreover, we examined the moderating effect of task interdependence. CPBs are considered in light of four dimensions, namely parasitism, interpersonal aggression, boastfulness, and misuse of resources. Design/Methodology/Approach  Data were collected from a sample of 249 individuals working in a Canadian prison. The study was based on two measurement times. Findings  The results reveal that the four dimensions of CPBs are negatively related to psychological well-being and that relationships involving interpersonal aggression and boastfulness are moderated by task interdependence. Implications  This study highlights the importance for managers to identify the presence of CPBs in their team as soon as possible so as to be able to remedy them before they affect team members’ psychological well-being. Moreover, interpersonal aggression and boastfulness may be particularly detrimental in a context of high interdependence. Originality/Value  This study further extends the nomological network of CPBs. Indeed, the results indicate that the presence of CPBs may harm employees’ mental health. Furthermore, this study shows that a contextual characteristic (i.e., task interdependence) may amplify the detrimental effect of some CPBs.

Do health behaviors explain the effect of neuroticism on mortality? Longitudinal findings from the VA Normative Aging Study

Studies have shown that higher levels of neuroticism are associated with greater risk of mortality. Yet what accounts for this association? One major theoretical position holds that persons higher in neuroticism engage in poorer health behaviors, such as smoking and excessive drinking, thus leading to earlier death. We tested this hypothesis using 30-year mortality in 1788 men from the VA Normative Aging Study. Using proportional hazards (Cox) models we found that one health behavior, smoking, attenuated the effect of neuroticism on mortality by 40%. However, 60% remained unexplained, suggesting that the effects of other pathways (e.g., biological) also influence the relationship between neuroticism and mortality.     

Fluid intelligence is independently associated with all-cause mortality over 17 years in an elderly community sample: An investigation of potential mechanisms

The long-term relationship between lower intelligence and mortality risk in later life is well established, even when controlling for a range of health and sociodemographic measures. However, there is some evidence for differential effects in various domains of cognitive performance. Specifically, tests of fluid intelligence may have a stronger association with mortality than do tests of crystallized intelligence. The present study examines the relationship between intelligence and mortality in a sample of 896 Australian community-dwelling males and females, aged 70–97 at recruitment and followed for up to 17 years. There were 687 deaths during the follow-up period. Cox proportional hazard regression models examined whether the relationship between intelligence and mortality might be mediated by socioeconomic status, by health behaviors, by health status, or a combination of these. Higher fluid intelligence — as measured by the Symbol–Letter Modalities Test — was strongly associated with lower mortality rates (Hazard ratio = 0.80; 95% confidence interval = 0.72–0.88), even after accounting for any combination of potential mediators and confounders. A significant association between crystallized intelligence, as measured by the National Adult Reading Test, and mortality (HR = 0.89; 95% CI = 0.80–0.99) was attenuated by the inclusion of socioeconomic, health status measures, and health behavior measures and when deaths from the first four years of the study were excluded. The findings show little support for the hypothesized mechanisms of the intelligence–mortality relationship.
