该文对Rips提出的“证明心理学理论”做了综合述评。这一理论主要包含三方面的内容:对推理过程与人类记忆相互关系的解释;(2)根据逻辑学中的“自然推理规则”进行修正后用于解释人类推理过程的推理规则;(3)关于如何控制推理过程的论述。Rips认为他于1983年设计并实施的以“自然推理系统”所含各推理规则为实验材料的实验结果支持该理论的基本观点。 相似文献

A group ethos permeates the two Special Issues of Group dedicated to the future of group psychotherapy in the 21st century. This ethos is elaborated through a parable, an integration of authors' conclusions, and a brief exploration of the myths and basic assumptions about group leadership and followership that characterized the 20th century. A new basic assumption is proposed for the 21st. BaC suggests that members are drawn to groups for the unconscious collaboration necessary to discover something between them, as yet untold—something that may hold the key to their own fates and to the human condition. 相似文献

We present a new prefixed tableau system for verification of validity in modal logic . The system is deterministic, it uniquely generates exactly one proof tree for each clausal representation of formulas, and, moreover, it uses some syntactic reductions of prefixes. is defined in the original methodology of tableau systems, without any external technique such as backtracking, backjumping, etc. Since all the necessary bookkeeping is built into the rules, the system is not only a basis for a validity algorithm, but is itself a decision procedure. We present also a deterministic tableau decision procedure which is an extension of and can be used for the global assumptions problem. 相似文献

ABSTRACT— Effective managers recognize both positive and negative changes in employee performance and take appropriate remedial action when required. Managers' assumptions about the rigidity or malleability of personal attributes (e.g., ability and personality) affect their performance of these critical personnel management tasks. To the extent that managers assume that personal attributes are fixed traits that are largely stable over time, they tend to inadequately recognize actual changes in employee performance and are disinclined to coach employees regarding how to improve their performance. However, a growth-mindset intervention can lead managers to relinquish their fixed mindset and subsequently provide more accurate performance appraisals and helpful employee coaching. Implications for performance evaluation procedures and avenues for future research are outlined. 相似文献

ObjectiveThe current study aimed to provide a subcultural analysis of mental toughness in a high-performance context in sport.DesignUsing Schein's (1990) framework of organisational culture, an exploratory qualitative analysis, employing focus group and individual interviews, was used to investigate mental toughness in an Australian Football League club.MethodNine senior coaches and players participated in focus group and individual interviews. Photo elicitation was used as a method to capture mental toughness through the identification of prominent club artefacts. Participants were considered to have significant subcultural knowledge of their football club and were willing to describe personal experiences and perceptions of mental toughness through this cultural lens. Deductive and inductive analyses were conducted to capture the core themes of mental toughness across the disparate levels of Schein's organisational framework.ResultsMental toughness was found to be a socially derived term marked by unrelenting standards and sacrificial displays. These acts were underpinned by subcultural values emphasising a desire for constant improvement, a team first ethos, relentless effort, and the maintenance of an infallible image. At its core, mental toughness was assumed to be an internal concept, epitomised an idealised form of masculinity, elitist values, and was rhetorically depicted through metaphors of war.ConclusionsIt may be difficult to understand mental toughness without giving attention to the contextual norms related to the term. Appreciating how people promote, instil, and internalise prized ideals coveted as mental toughness could be intriguing for future research in sport psychology. 相似文献

After more then 50 years of probabilistic choice modeling in economics, marketing, political science, psychology, and related disciplines, theoretical and computational advances give scholars access to a sophisticated array of modeling and inference resources. We review some important, but perhaps often overlooked, properties of major classes of probabilistic choice models. For within‐respondent applications, we discuss which models require repeated choices by an individual to be independent and response probabilities to be stationary. We show how some model classes, but not others, are invariant over variable preferences, variable utilities, or variable choice probabilities. These models, but not others, accommodate pooling of responses or averaging of choice proportions within participant when underlying parameters vary across observations. These, but not others, permit pooling/averaging across respondents in the presence of individual differences. We also review the role of independence and stationarity in statistical inference, including for probabilistic choice models that, themselves, do not require those properties.

Trust is a critical component of research: trust in the work of co-workers and colleagues within the scientific community;
trust in the work of research scientists by the non-research community. A wide range of factors, including internally and
externally generated pressures and practical and personal limitations, affect the research process. The extent to which these
factors are understood and appreciated influence the development of trust in scientific research findings. 相似文献

Data cleaning has long been shown to be an essential step in data analysis but its application is not systematic and varies between researchers. The aim of the present article is to study the effect of the different elements of data cleaning and to give recommendations. The steps considered are normality, outliers and missing values. Firstly, we advise a close examination of the data and its normality with a view to transformation. Secondly, we look at outliers and their treatment (trimming and winsorizing). Lastly, we turn our attention to missing values and how to deal with them depending on their randomness. We also cover the importance of visualizing data before analysis. Finally, we illustrate the effect of these data cleaning practices on a real data set. We show that data cleaning can lead to a significant result becoming non-significant and therefore demonstrate the importance of these steps before starting data analysis. 相似文献
