In the widely used Corsi Block Test and Wechsler Spatial Span Tests, participants must reproduce sequences of blocks in the order touched by the examiner until two trials are missed at the same sequence length. The examiner records either the maximum number of blocks correctly reported or the total number of correct lists. Here, we describe a computerized spatial span test (C-SST) that uses psychophysical procedures to quantify visuospatial mean span (MnS) with sub-digit precision. Results from 187 participants ranging in age from 18 to 82 years showed that accuracy declined gradually with list length around the MnS (by ~30% per item). Simulation studies revealed high variance and biases in CBT and Wechsler measures, and demonstrated that the C-SST provided the most accurate estimate of true span (i.e., the sequence length producing 50% correct). MnS declined more rapidly with age than mean digit span (MnDS) measured in the same participants. Response times correlated with both MnS and MnDS scores. Error analysis showed that omission and transposition errors predominated, with weaker primacy and recency effects in spatial span than digit span testing. The C-SST improves the precision of spatial span testing and reveals significant differences between visuospatial and verbal working memory. 相似文献

While many thoughts and mental images that people form about their personal future refer to emotionally significant events, there is still little empirical data on the frequency and nature of emotional future-oriented thoughts (EmoFTs) that occur in natural settings. In the present study, participants recorded EmoFTs occurring in daily life and rated their characteristics, emotional properties, and perceived functions. The results showed that EmoFTs are frequent, occur in various contexts, and are perceived to fulfil important functions, mostly related to goal pursuit and emotion regulation. When distinguishing between anticipatory and anticipated emotions (i.e., emotions experienced in the present versus emotions expected to occur in the future), a positivity bias in the frequency of EmoFTs was found to be restricted to anticipated emotions. The representational format and perceived function of EmoFTs varied according to their affective valence, and the intensity of anticipatory and anticipated emotions were influenced by the personal importance and amount of visual imagery of EmoFTs. Mood states preceding EmoFTs influenced their emotional components, which, in turn, impacted ensuing mood states. Overall, these findings shed further light on the emotional properties of future-oriented thoughts that are experienced in daily life. 相似文献

According to the constructive episodic simulation hypothesis, remembering and episodic future thinking are supported by a common set of constructive processes. In the present study, we directly addressed this assertion in the context of third-person perspectives that arise during remembering and episodic future thought. Specifically, we examined the frequency with which participants remembered past events or imagined future events from third-person perspectives. We also examined the different viewpoints from which third-person perspective events were remembered or imagined. Although future events were somewhat more likely to be imagined from a third-person perspective, the spatial viewpoint distributions of third-person perspectives characterizing remembered and imagined events were highly similar. These results suggest that a similar constructive mechanism may be at work when people remember events from a perspective that could not have been experienced in the past and when they imagine events from a perspective that could not be experienced in the future. The findings are discussed in terms of their consistency with—and as extensions of—the constructive episodic simulation hypothesis. 相似文献

The Persuasive Effects of Emotive Visual Imagery: Superficial Manipulation or the Product of Passionate Reason? 总被引:1,自引:0,他引:1
This study reevaluates the persuasive impact of emotional visual appeals within politics and examines two different explanations for their effects. One possibility is that the effects of emotive visual images are essentially superficial in nature, consistent with the view that feelings aroused by an affective image are transferred somewhat mechanically to a political candidate or cause with which it is paired. This transfer-of-affect explanation suggests that emotional appeals may work best among the least informed voters or those paying the least attention to a persuasive political message. The second possibility is that emotional appeals work via passionate reason, in which affective responses to an emotive image are integrated with, and potentially bias, reasoned thought about the accompanying message. This integrated approach leads to the counterintuitive prediction that individuals who are most highly involved in an issue (and who know the most about it) are most influenced by emotional imagery. This prediction arises from growing evidence that people highly involved in value-laden social issues generate the strongest emotional responses to issue-related persuasive appeals. These two models were tested in a study in which undergraduate students were presented with a picture of a cute or an ugly animal and a flyer from an organization advocating a pro- or anti-environment stance with respect to preserving the animal's habitat. The responses showed that emotive imagery was most persuasive among the most involved environment supporters, providing clear evidence of passionate reasoning. 相似文献

近年来,社会变迁导致的文化、心理与行为变化及其相互建构已经成为心理学的研究热点。社会变迁研究通常涉及和变迁相关的时间效应、时代效应以及和变迁无关的年龄效应。在考察变迁趋势及其影响因素时,常用的研究设计有跨时间比较、跨代际比较、跨地区比较(历史重构)等方法;常用的分析方法有传统的相关和回归分析和现代的时间序列分析(比如交叉滞后相关和格兰杰因果检验)等。由于每一种设计都有其优点和不足,在具体研究中,研究者要根据研究的问题和可操作性选择合适的方法;如果可能,最好同时采用多种方法,以寻求基于不同方法的聚合证据。 相似文献

In order to improve the distribution system for the Nordic countries the BASF AG considered 13 alternative scenarios to the existing system. These involved the construction of warehouses at various locations. For every scenario the transportation, storage, and handling cost incurred was to be as low as possible, where restrictions on the delivery time were given. The scenarios were evaluated according to (minimal) total cost and weighted average delivery time. The results led to a restriction to only three cases involving only one new warehouse each. For these, a more accurate model for the cost was developed and evaluated, yielding results similar to a simple linear model. Since there were no clear preferences between cost and delivery time, the final decision was chosen to represent a compromise between the two criteria. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

相对稳定的负性认知特征会使个体容易发生抑郁,被称为抑郁认知易感性.文章总结并对比当前关于抑郁认知易感性的稳定性与可变性的观点,提出从儿童发展早期开始研究认知易感性因素的必要性.接着回顾消极归因方式、功能失调态度和冗思这三种认知易感性因素在儿童期的表现及其前期心理特征,试图找到抑郁认知易感性在个体发展中的连续性.建议今后探讨认知易感性因素在不同年龄的发展特点,关注发展早期认知易感性因素的测量. 相似文献

In investigations into perception-action systems, variability of observable behavior may be considered to (a) interfere with inquiry, (b) be neither detrimental nor particularly useful to inquiry, or (c) play a crucial role in inquiry. The authors underscore recent suggestions that alternative (c) is a preferred strategy for the study of many motor behaviors. In tutorial fashion, the authors review the concepts of variability and determinism with respect to postural and rhythmic movements. Study of the variability of those behaviors has revealed crucial features suggestive of underlying mechanisms and control, such as particular blends of noise and determinism (piecewise determinism). It has also revealed general lessons (for example, more variable does not mean more random and more controllable does not mean more deterministic) that may extend to other classes of perceptual-motor behavior. 相似文献
