采用图文相继呈现、文本逐句阅读的范式,通过反应时技术与出声思维的方法考察了组织型插图对不同认知方式个体说明性文本阅读过程与阅读结果的影响,结果发现,与单一文本相比,场独立个体在有插图条件下的阅读成绩显著提高,而阅读时间没有增加,并产生了更多的推理、细化和提问策略;而场依存个体在有插图条件下的阅读成绩显著提高,阅读时间也显著增多,而理解策略没有变化。这说明组织型插图对两种认知方式个体说明性文本的阅读均起到促进作用,但场独立个体没有因为增加组织型插图而付出更多的加工努力,而是通过调整理解策略的方式来提高阅读效果;而场依存个体在阅读过程中没有根据组织型插图调整理解策略,阅读效果的提高是以付出更多的加工努力为代价的。 相似文献

Within the scientific study of spirituality there are substantial ambiguities and uncertainties about relevant concepts, terms, evidences, methods, and relationships. Different disciplinary approaches reveal or emphasize different aspects of spirituality, such as outcomes, behaviors, skills, ambitions, and beliefs. I argue that these aspects interdepend in a way that constitutes a “systems model of spirituality.” This model enables a more holistic understanding of the nature of spirituality, and suggests a new definition that disambiguates spirituality from related concepts such as religion, cultural sophistication, and prosocial behavior in animals. It also exposes important open questions about the nature of spirituality. To support the emerging scientific approach to the study of spirituality, I propose the development of a “philosophy of spirituality” that can clarify the conceptual terrain, identify important research directions, and facilitate a comprehensive and interdisciplinary investigation into the nature, validity, and implications of spirituality's conceptual and practical entailments. 相似文献

To explore how model building adapts to changing environments, we had participants play “rock‐paper‐scissors” against a computer that played a frequency bias or a player‐dependent bias and then switched. Participants demonstrated their use of prior experience in how quickly they recognized and exploited changes in the computer's play strategy; in general, the more similar the strategies, the more efficient the updating. These findings inform our understanding of previously reported updating impairments in right‐brain damaged patients. 相似文献

The original version and an evaluatively neutralized version (with items rephrased to reduce popularity) of a personality inventory were compared. The results revealed (i) similar criterion validity across three different sets of self‐rated behaviours, (ii) stronger relations to the rated social desirability of criteria for the original version and (iii) less correlation between factors for the neutralized version. We take the results to indicate that evaluative neutralization is a viable technique for reducing social desirability in self‐ratings. Implications for test construction are discussed.

自身免疫性胰腺炎(AIP)是一种特殊类型的慢性胰腺炎,以胰腺肿大及胰管不规则狭窄为特征.AIP分两个亚型:Ⅰ型AIP好发于亚洲老年人,为淋巴浆细胞硬化性胰腺炎;Ⅱ型AIP多见于西方人,为导管中心型胰腺炎.AIP缺乏特异性血清标志物,诊断主要依赖于其特征性改变.依据AIP诊断标准国际共识,AIP的诊断包括影像学、血清学、胰腺外器官受累、组织病理学和诊断性激素治疗5个方面.糖皮质激素是AIP的首选治疗方法,但复发率高,免疫调节剂对维持AIP的持续缓解具有一定作用.AIP总体预后良好,胰管结石和癌变是其潜在的并发症,但发生率极低. 相似文献

Diagnostic work is the reflexive work of figuring out what issues are at stake and determining the scope for action. This work is not generally accommodated by evidence-based guidelines, which generally promote a uniform, predefined approach to solving healthcare problems that risk narrowing the opportunities for diagnostic work in healthcare practice. Consequently, guidelines are often criticised as too general to solve situated, individual healthcare problems and gaps between guidelines and their implementation are often reported. The Netherlands has developed a guideline for problem behaviour in elderly care, explicitly designed for diagnostic work, thus stimulating a situated approach. Relational problem behaviour is highly embedded in its context. The guideline stimulates diagnostic work, which helps to unravel problem behaviour and is opening alternatives in elderly care. Diagnostic work does not transfer guideline development problems to healthcare practice, but simply structures the decision-making process without giving a predefined answer. Diagnostic work is thus important to consider in order to avoid a gap between guideline development and implementation. 相似文献

On the Decision to Explore New Alternatives: The Coexistence of Under‐ and Over‐exploration 下载免费PDF全文
The decision whether to explore new alternatives or to choose from familiar ones is implicit in many of our daily activities. How is this decision made? When will deviation from optimal exploration be observed? The current paper examines exploration decisions in the context of a multi‐alternative “decisions from experience” task. In each trial, participants could choose a familiar option (the status quo) or a new alternative (risky exploration). The observed exploration rates were more sensitive to the frequent outcome from choosing new alternatives than to the average outcome. That is, the implicit decision whether to explore a new alternative reflects underweighting of rare events: Over‐exploration was documented in “Rare Disasters” environments, and insufficient exploration was evident in “Rare Treasures” environments. In addition, the results reveal a decrease in exploration of new alternatives over time even when it is always optimal and some exploration even when it is never reinforcing. These results can be captured with models that share a distinction between “data collection” and “outcome‐driven” decision modes. Under the data collection mode, the decision maker collects information about the environment, to be used in future choices. Under the outcome‐driven mode, the decision maker relies on small samples of previous experiences with familiar versus unfamiliar alternatives, before the selection of a specific alternative. The predictive value of a two‐parameter “explorative sampler” quantification of these assumptions is demonstrated. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

Social comparison (i.e., body, eating, exercise) and body surveillance were tested as mediators of the thin-ideal internalization-body dissatisfaction relationship in the context of an elaborated sociocultural model of disordered eating. Participants were 219 college women who completed two questionnaire sessions 3 months apart. The cross-sectional elaborated sociocultural model (i.e., including social comparison and body surveillance as mediators of the thin-ideal internalization-body dissatisfaction relation) provided a good fit to the data, and the total indirect effect from thin-ideal internalization to body dissatisfaction through the mediators was significant. Social comparison emerged as a significant specific mediator while body surveillance did not. The mediation model did not hold prospectively; however, social comparison accounted for unique variance in body dissatisfaction and disordered eating 3 months later. Results suggest that thin-ideal internalization may not be “automatically” associated with body dissatisfaction and that it may be especially important to target comparison in prevention and intervention efforts. 相似文献
