Along with an increasing interest in the plasticity and role of personality across the adult lifespan comes the need for a diverse set of innovative statistical approaches to study it. With this paper, we set out to illustrate some of the possibilities and challenges in modelling age‐related differences and time‐related changes in personality psychology by means of dynamic panel models. To this end, we first distinguish between the study of age‐related differences and time‐related changes and demonstrate how the treatment of age and time as either discrete or continuous variables implies important modelling choices. Second, we present a selection of four example cases that address the topic of age moderation in diverse matters and with different objectives. Based on our cross‐tabulation of age and time as discrete and continuous variables, the first two example cases represent fairly well‐established models (cases A and B), whereas the remaining cases are used to illustrate current developments in the field (cases C and D). We close the paper with some final remarks on current limitation and future research directions. © 2019 European Association of Personality Psychology 相似文献

Two experiments investigated whether individuals' forecasts of the demand for products and a stock market index assuming a best or worst case scenario depend on whether they have seen a single scenario in isolation or whether they have also seen a second scenario presenting an opposing view of the future. Normatively, scenarios should be regarded as belonging to different plausible future worlds so that the judged implications of one scenario should not be affected when other scenarios are available. However, the results provided evidence of contrast effects in that the presentation of a second “opposite” scenario led to more extreme forecasts consistent with the polarity of the original scenario. In addition, people were more confident about their forecasts based on a given scenario when two opposing scenarios were available. We examine the implications of our findings for the elicitation of point forecasts and judgmental prediction intervals and the biases that are often associated with them. 相似文献

Research on the mental representation of time (‘subjective time’) has provided broad insights into the nature of time perception and temporal processing. As the field comprises different scientific disciplines, such as psychology, philosophy, and neuroscience, studies differ with regard to the basic terms and concepts used. For this reason, research on subjective time lacks a coherent conceptual system. We argue that research in the field of subjective time should aim at establishing such a system, i.e., a more standardized terminology, in order to strengthen its theoretical basis and to support an efficient communication of results. Based on key empirical findings and concepts that are commonly (but inconsistently) used in the literature, we argue for a conceptual framework for the study of subjective time that differentiates between three types of mental representations of time: basic temporal processing, time perception in terms of passage, and time perception in terms of duration. 相似文献

成瘾行为给个体和社会带来了严重的危害。对成瘾人群时间洞察力的研究成为探讨成瘾行为产生和发展的一个新的视角。过去消极、现在享乐和现在宿命时间洞察力取向的个体更可能出现成瘾行为, 而未来时间洞察力取向则是成瘾行为的一个保护性因素, 它不仅可以减少成瘾行为的发生, 也有利于成瘾行为的康复。从自我调节, 冲动性决策等行为机制和前额叶的神经机制方面可以帮助我们深入理解时间洞察力对成瘾行为的影响。未来研究可以进一步探讨不同成瘾行为者时间洞察力的一致性与特异性; 采用纵向研究方法探讨成瘾者时间洞察力的动态变化过程; 对成瘾者的洞察力进行干预, 增加成瘾者的未来时间洞察力, 减少其过去消极和现在时间洞察力取向来帮助成瘾者实现时间洞察力的平衡, 从而提高其戒断效果。 相似文献

摘要
为了考察预期想象对不同拖延水平个体拖延行为的影响,本研究采用一般拖延量表(General Procrastination Scale)选取高拖延被试和低拖延被试,要求被试在进行模拟现实的拖延任务之前分别对任务过程和任务结果进行预期想象,比较不同拖延水平的被试在预期想象作用下拖延行为的变化。结果表明:(1)在两组被试中,相比于无想象条件下的拖延行为,对任务过程的预期想象增强拖延行为,对任务结果的预期想象削弱拖延行为;(2)对任务不同成分的预期想象所引发的情绪与拖延行为的变化相关显著。这说明情绪和预期想象是影响拖延的重要因素,合理地操纵对任务不同成分的预期想象可以有效干预拖延行为。 相似文献

在视觉工作记忆加工过程中, 对记忆项目的维持及操作需要将转瞬即逝的感觉输入转换为稳定的记忆表征, 这一加工过程被定义为视觉工作记忆巩固。鉴于巩固在视觉工作记忆中所起到的“门控”作用, 研究者们已经发展出多种研究范式对其可能涉及的运作机制进行探讨。然而, 在不同范式下所观察到的巩固时程存在较大差异, 其所遵循的巩固模式也尚不清晰。此外, 对于巩固所涉及的理论及神经机制亦存在不同的观点。通过对比不同范式的差异性及梳理各方的观点, 可以有效推动这些问题的解决。未来研究除了可以在多种范式下对巩固模式进行验证, 还可以探究注意在巩固中的作用, 以及项目熟悉性等因素会对巩固加工产生何种影响。 相似文献

This study used a dual task with participants of different levels of cognitive capacities, assessed with neuropsychological tests, to examine the attentional cost on time judgment of processing concurrent temporal and non-temporal information. Children and adults performed a temporal reproduction task with either an interfering temporal or non-temporal discrimination task. The results showed an underestimation of time in the dual task compared to the single task, the extent of which was directly linked to individual attentional capacities. However, the non-temporal task interfered more than the temporal task on the reproduced durations. Nonetheless, the temporal reproduction task equally affected performance in the non-temporal and the temporal discrimination task. These results reveal the predominant role of the cost of dual-tasking in interference effects on time judgment, and the lesser role of concurrent information, especially of temporal information. This suggests a lack of competition for attentional resources in the processing of multiple durations. 相似文献

情节式未来思考是个体将自我投射到未来以预先经历某事件的能力,个人目标加工在情节式未来思考中发挥着重要作用。目前对情节式未来思考中目标加工的行为学研究通常将其划分为目标过程模拟和目标结果模拟两种类型,以探究其对执行意图的影响为主;脑机制神经影像学研究则聚焦于默认网络的内侧前额叶和后扣带的重要作用,以及默认网络、额顶控制网络和奖赏区的协同作用。未来研究应进一步探讨情节式未来思考目标加工的形式、年龄差异及其与时间距离的关系。 相似文献

Humans show a systematic tendency to perceive the future as psychologically closer than the past. Based on the clinical hypothesis that anxiety would be associated more with future threat life events, whereas depression with past loss events, here we explored whether people with anxiety- and depression-related personality traits perceive differently the psychological distance of temporal events. Results showed that the common tendency to perceive the future as psychologically closer than the past is exaggerated in individuals with anxiety-related personality traits, whereas this asymmetry drastically shrinks in individuals with depression-related personality traits. Beyond substantiating the hypothesis that the past and the future are differently faced by people with depression- and anxiety-related personality traits, the present findings suggest that temporal orientation of one’s self may be greatly altered in anxiety and depression. 相似文献
