Research suggests that the temporal distance from decision outcomes leads to divergent decisions for the near and the distal future. As such, high‐level idealistic concerns and values dominate decisions for the distant future, whereas low‐level pragmatic concerns play a greater role in decisions for the near future. We examined how individual differences in future time orientation are related to decisions vis‐à‐vis the near versus the distal future. The results of three studies, with participants with varying levels of expertise—students (Studies 2 and 3), teachers (Study 1), and school principals (Study 2)—show that principals tend to be overall more idealistic in their choices. Yet discrepancies between decisions for the near versus the distal future exist among all three levels of expertise. However, this dominance of idealistic over pragmatic concerns for more distant future decisions effect was smaller the higher the future time orientation was (whether measured or manipulated). Implications for educational and managerial decision making and training are discussed. Copyright © 2017 John Wiley & Sons, Ltd. 相似文献

Hailed as the gold standard, the randomized controlled trial (RCT) occupies a hegemonic position at the top of evidence-based medicine’s hierarchy of knowledge. It is testament to the methodology’s capacity for standardization that it can so readily be spoken of in the singular: the RCT. Under what conditions, then, is it possible to speak of change in the gold standard? Since the 1950s, alternative versions of the RCT have been advocated for under the banner of ‘adaptive design’. Adaptive designs allow investigators to make pre-planned changes to a trial on the basis of accruing information while the experiment is ongoing. Initially a niche topic of methodological debate among biostatisticians, the approach is becoming widespread in mainstream drug development. A genealogical analysis exposes the discursive moves used to justify and popularize adaptation, from a focus on patient well-being and the greater good in the 1960s and 1970s, to efficiency and virtualism in the 1990s and 2000s. Changing discourses of time and patienthood have facilitated a move away from standardization as the singular logic of trials towards an appreciation of flexibility, undergirded by probabilistic methodologies. Adams et al.’s [(2009). Anticipation: Technoscience, life, affect, temporality, Subjectivity, 28, pp. 246–265] conceptual framework of anticipation illuminates this evolving moral economy of medical research, in which modes of knowledge production which claim to know the future are supplanting the traditional certainties of fixed and standardized experimental designs. Predictable uncertainty is the currency of this emerging economy, which capitalizes on computer simulation and ever more sophisticated tools of prediction to leverage credibility. 相似文献

The study behaviours of students can be assessed from several perspectives, such as what study strategies are used, the total number of hours of study, and the distribution of studying over time. Here, we present the results of a survey study that considered each of these perspectives by asking students to report the what, how much, and when of their study behaviours over the course of a semester. As important, to better understand students’ use of study strategies, we also had students report at the beginning of the semester how they intended to study and their beliefs about the effectiveness of a variety of common strategies. Our results indicate that during the semester, students rely on relatively ineffective strategies and mass their studying the day or two before an exam. However, students intended to begin studying earlier and to use a mix of effective and ineffective study habits. Despite their use of some ineffective strategies, they did have a relatively accurate assessment of which strategies were less versus more effective. Taken together, our results suggest that students have some excellent intentions but may falter because massing study the evening before an exam limits their use of more effective study strategies. 相似文献

In this paper, I develop and defend the ‘Justified Decision Perspective’ (JDP) in answer to the question of when we should regret the things we have done. I claim that one should not regret a past decision one has made so long as it was justified in relation to the kind of person one was at the time of acting. On this time-indexing account, judging a decision to be justified – at least for the purposes of assessing one’s regrets – is a matter of identifying the practical reasons that were epistemically available to the agent when she was deliberating about what to do. Accordingly, when responding to her regrets, an agent should not invoke (a) reasons that existed but were epistemically unavailable to her when she was deliberating; or (b) reasons that only came into existence after she acted. The JDP has important implications for prospective regret. In particular, it implies we should worry less about experiencing regret in the future than many of us do. Thus, my overall aim is to show that we often have reason to reject our regrets, which means that regret should play a less prominent and painful role in our lives than it does currently. 相似文献

Childhood abuse, anger, drug-related problems, and self-harm are commonly seen among incarcerated individuals. Forty-three young incarcerated males from an Istanbul prison were assessed for childhood abuse, anger, drug use, self-harming behavior, and executive function (EF). Further, 58% of the sample was using drugs, and 60.5% showed self-harming behavior. Performing a backward stepwise binary logistic regression model, it was found that the likelihood of using drugs was determined by EF measured by the Trail Making Test form A, childhood abuse, anger, and self-harm. On the other hand, self-harm was determined by childhood abuse, anger, and drug use. 相似文献

IntroductionCannabis is the most commonly used illicit drug with the highest prevalence reported among 15- to 24-year-olds. This specific period of emerging adulthood constitutes a critical age for substance use and for future consumption. Cannabis use patterns change during college or university and the post-college transition; users are at greater risk of adverse health outcomes (especially if they start or maintain a pattern of frequent use).ObjectivesThe overall aim of this study was to highlight psychological and relational factors that might be associated with changes (including cessation and fluctuation) in cannabis use during this specific period, separately for males and females.MethodsThe subjects were 682 first-year college students (69.94% of female), aged between 18 and 25 years (M = 18.59 years, SD = 1.56). Four groups were formed according to cannabis consumption: “non-users” (54.64%), “desisting users” (14.04%), “fluctuating users” (16.23%), and “persistent users” (15.07%). A self-report questionnaire was administered to evaluate prevalence, frequency and trajectory of use, number of peer cannabis users, alcohol use, impulsivity, anxiety (trait and social) and depression.ResultsFemales appear more sensitive to the romantic partner's consumption than males. For both sexes, having more friends who use cannabis appears to be a determinant. Depression and anxiety were not related to changes in cannabis use. Impulsivity is a significant factor for the maintenance of cannabis use in emerging adulthood, with higher lack of premeditation for males and higher sensation seeking for females among fluctuating and persistent users.ConclusionsResults are discussed in terms of maintenance of use and the spiral of consumption, including clinical implications for prevention and interventions. 相似文献

Theories relating to time perception and motor performance predict very different temporal distortions depending on the synchronisation or succession of temporal processing and motor behaviour. However, our knowledge about the temporal difference between motor preparation and execution is still scarce. In order to expand on prior studies, two different time reproduction tasks were utilised to measure motor preparation and motor execution. We found that motor preparation of a planned action allows participants to complete the time reproduction task more accurately and, in short duration trials, less variably than for motor execution. Furthermore, under-reproduction was found in motor preparation compared to motor execution, which may be caused by increased temporal information processing. According to the attentional gate theory, more attention allocated to time processing and reduced motor distraction leads to less temporal distortion in the motor preparation. The findings are also important for designing to study consciousness, temporal and visual processing. 相似文献

通过2个实验, 考察了空间隐喻和形状变化对物体内隐时间概念加工的影响。实验1通过对隐含时间关系的词对的语义相关判断发现, 形状变化物体隐含的“先前/后来”的时间概念与“左/右”的空间概念存在着对应关系, 断裂式变化(形状变化大)的物体比渐进式变化(形状变化小)的物体激发了更加明显的时间变化感, 但物体形状变化类型并未明显地影响对词对语义相关判断的速度和准确性。实验2通过对隐含时间关系的物体图片对的语义相关判断发现, 物体形状变化隐含的“先前/后来”的时间概念与“左/右”的空间概念亦存在着对应关系, 而且物体形状变化类型影响对物体图片对语义相关判断的速度和准确性, 被试对渐进式变化物体的语义相关判断显著快于对断裂式变化物体的语义相关判断, 错误率亦低。整个研究表明, 在物体形状变化内隐时间概念的表征中, 既存在着抽象的符号表征, 又存在着具体的形状知觉表征。研究结果支持概念双加工理论的预言。 相似文献

Language has been linked to spatial representation and behavior in humans, but the nature of this effect is debated. Here, we test whether simple verbal expressions improve 4-year-old children’s performance in a disoriented search task in a small rectangular room with a single red landmark wall. Disoriented children’s landmark-guided search for a hidden object was dramatically enhanced when the experimenter used certain verbal expressions to designate the landmark during the hiding event. Both a spatial expression (“I’m hiding the sticker at the red/white wall”) and a non-spatial but task-relevant expression (“The red/white wall can help you get the sticker”) enhanced children’s search, relative to uncued controls. By contrast, a verbal expression that drew attention to the landmark in a task-irrelevant manner (“Look at this pretty red/white wall”) produced no such enhancement. These findings provide further evidence that language changes spatial behavior in children and illuminate one mechanism through which language exerts its effect: by helping children understand the relevance of landmarks for encoding locations. 相似文献
