顿悟的原型启发效应机制探索

以中国传统的字谜作为实验材料,采用"多个原型字谜学习-多个目标字谜测试"两阶段实验范式,对顿悟过程的原型启发机制进行了探讨.考察了原型启发效应是否会受第一阶段学习的原型字谜的数量以及启发量大小的影响,结果发现:学习的原型字谜的数量对原型启发效应的大小没有显著影响;启发量高低对原型启发效应的大小有显著影响.这一结果支持了"原型字谜的激活是一种自动加工、原型字谜中所隐含的关键启发信息的激活是一种控制加工"的观点.     

Topic-relevant cognition and empathic accuracy in laboratory discussions of safer sex

Abstract

The present study sought to identify some of the mechanisms that make safer sex such a difficult topic to talk about. Fifty six dating couples participated in a laboratory study in which the opposite-sex members of two pairs of couples engaged in two discussions of safer sex (or a control topic), each time with a different opposite-sex partner (their own dating partner or an opposite-sex stranger). The results indicated that discussions of safer sex evoke in dating partners a high level of perceived goal-incompatibility, difficulty maintaining one's focus on the topic, and difficulty in reading the other partner's thoughts and feelings. These reactions did not occur in response to the control topic. This initial demonstration study is important with respect to the processes it implicates, but further clarification is needed regarding the specific real-life conditions in which these processes do, and do not, occur.     

From a single-level analysis to a multilevel analysis of single-case experimental designs

Multilevel modeling provides one approach to synthesizing single-case experimental design data. In this study, we present the multilevel model (the two-level and the three-level models) for summarizing single-case results over cases, over studies, or both. In addition to the basic multilevel models, we elaborate on several plausible alternative models. We apply the proposed models to real datasets and investigate to what extent the estimated treatment effect is dependent on the modeling specifications and the underlying assumptions. By considering a range of plausible models and assumptions, researchers can determine the degree to which the effect estimates and conclusions are sensitive to the specific assumptions made. If the same conclusions are reached across a range of plausible assumptions, confidence in the conclusions can be enhanced. We advise researchers not to focus on one model but conduct multiple plausible multilevel analyses and investigate whether the results depend on the modeling options.     

Enumeration versus multiple object tracking: the case of action video game players

Here, we demonstrate that action video game play enhances subjects' ability in two tasks thought to indicate the number of items that can be apprehended. Using an enumeration task, in which participants have to determine the number of quickly flashed squares, accuracy measures showed a near ceiling performance for low numerosities and a sharp drop in performance once a critical number of squares was reached. Importantly, this critical number was higher by about two items in video game players (VGPs) than in non-video game players (NVGPs). A following control study indicated that this improvement was not due to an enhanced ability to instantly apprehend the numerosity of the display, a process known as subitizing, but rather due to an enhancement in the slower more serial process of counting. To confirm that video game play facilitates the processing of multiple objects at once, we compared VGPs and NVGPs on the multiple object tracking task (MOT), which requires the allocation of attention to several items over time. VGPs were able to successfully track approximately two more items than NVGPs. Furthermore, NVGPs trained on an action video game established the causal effect of game playing in the enhanced performance on the two tasks. Together, these studies confirm the view that playing action video games enhances the number of objects that can be apprehended and suggest that this enhancement is mediated by changes in visual short-term memory skills.     

Discussions Quinton’s Neglected Argument for Scientific Realism

Summary  This paper discusses an argument for scientific realism put forward by Anthony Quinton in The Nature of Things. The argument – here called the controlled continuity argument – seems to have received no attention in the literature, apparently because it may easily be mistaken for a better-known argument, Grover Maxwell’s “argument from the continuum”. It is argued here that, in point of fact, the two are quite distinct and that Quinton’s argument has several advantages over Maxwell’s. The controlled continuity argument is also compared to Ian Hacking’s “argument from coincidence”. It is pointed out that both arguments are to a large extent independent from considerations about high-level scientific theories, and that both are abductive arguments at the core. But these similarities do not dilute an important difference related to the fact that Quinton’s argument cleverly seeks to anchor belief in unobservable entities in realism about ordinary objects, which is a position shared by most contemporary scientific anti-realists.     

The Effects of Leader Support for Creativity and Leader Gender on Subordinate Creative Problem-Solving Performance

Ample correlational research shows that leader support for creativity is related to subordinate creativity, yet research examining the causality of this relationship experimentally is scant. Furthermore, most studies that demonstrate support for this relationship have used relatively subjective creativity measures that do not tap as effectively into the creative problem-solving process. Thus, we experimentally examined whether leader support for creativity affects subordinate creative problem-solving performance. We also examined whether this relationship depends on leader gender. We used experimental vignette methodology and a sample of 247 working adults to test these relationships. We found that high (vs. low) leader support for creativity resulted in a significantly higher number of ideas generated. Additionally, posthoc analyses showed that high (vs. low) leader support for creativity resulted in a significantly higher number of original ideas and higher number of quality ideas generated. We also found that when the leader was a woman (vs. man), average originality of ideas was significantly higher. We found no significant interactive effects of leader support for creativity and leader gender. We discuss how this study further elucidates our understanding of leader support for creativity, as well as avenues for future creativity research involving leader gender.     

意识和无意识的关系--实证的视角

意识和无意识的相互关系曾经是纯粹的哲学问题,科学心理学的诞生促进了对这一问题的实证视角考察。实证取向认为,意识和无意识同属人类心理的机能,并能够在外在的任务操作中表现出来。现代认知心理学发现了对应意识机能的外显过程和对应无意识机能的内隐过程,两者相对独立又共生共存。任何认知过程都是意识和无意识共同作用的产物,两者之间存在复杂的相互作用,并表现出权衡的特点。神经生理学的研究揭示了意识和无意识在发生学意义上可能的先后关系。无意识在心理过程中起的作用是普遍的、抽象的、抗干扰的,而意识则建筑在无意识的基础之上,有着更大的变异性。     

The influence of the Chinese sport system and Chinese cultural characteristics on Olympic sport psychology services

ObjectivesThe purpose of this study was to investigate the influence of sociocultural factors on Chinese Olympic sport psychology services.Design and methodsFifteen sport psychology consultants (SPCs), who served Chinese national teams for the 2008 Beijing Olympic Games, participated in this study after the Olympics. Semi-structured interviews were conducted within three months of the closing of the Olympics, followed by a hybrid approach to inductive and deductive thematic analyses.ResultsTwo general dimensions of sociocultural influence on Chinese Olympic sport psychology services were identified: (a) the Whole-Nation System and (b) Chinese cultural characteristics. They consisted of eight higher order themes, which comprised 26 lower order themes. This study revealed that Chinese sport psychology services were enhanced by recognizing the features of the Whole-Nation System (e.g., resource centralization and top-down management) and the successful blending of these features with Chinese cultural characteristics (e.g., holistic thinking style, keeping face and interpersonal order) into the psychological service.ConclusionsSociocultural factors had a marked influence on Chinese Olympic sport psychology services, which enabled Chinese SPCs to provide a culturally competent service (e.g., prioritizing collective interests, respecting the authority of administrative officials and coaches, and keeping face with others) for the Beijing Olympic Games.     

Philosophical Expertise and Philosophical Methodology

In recent years a new discussion on the nature of philosophical expertise has emerged: whether philosophers possess a special kind of expertise, what such expertise would entail, how to measure it, and related concerns. The aim of the present article is to clarify certain related points across these debates in the hope of paving a clearer path forward, by addressing the following. (1) The expertise defense, which seems central to many discussions on methodology and expertise, has been misconstrued at times. (2) Questions of expertise and methodology could be separated more clearly. (3) The study of expertise may be important in its own right; however, there may be good reasons to give priority to methodological concerns. (4) Finally, when viewed in light of methodological concerns, a new project emerges when engaging with recent contributions to the expertise debate. The present article attempts a brief outline of this project.
