IN PRAISE OF A LOGIC OF DEFINITIONS THAT TOLERATES Ω‐INCONSISTENCY

I argue that a general logic of definitions must tolerate ω‐inconsistency. I present a semantical scheme, , under which some definitions imply ω‐inconsistent sets of sentences. I draw attention to attractive features of this scheme, and I argue that yields the minimal general logic of definitions. I conclude that any acceptable general logic should permit definitions that generate ω‐inconsistency. This conclusion gains support from the application of to the theory of truth.     

To Brexit or not to Brexit: The roles of Islamophobia,conspiracist beliefs,and integrated threat in voting intentions for the United Kingdom European Union membership referendum

We used an identities approach to examine voting intentions in the June 2016 UK referendum on membership of the European Union (EU). In April 2016, 303 British adults (58.7% women, age M = 34.73) indicated their voting intentions for the referendum and completed measures of identification with the national in-group, perceived threat from Muslim immigrants, belief in Islamophobic conspiracy narratives, Islamophobia, general conspiracist beliefs, ambiguity tolerance, and belief in a clash of civilizations. Path and mediation analyses indicated that greater belief in Islamophobic conspiracy theories mediated the link between Islamophobia and intention to vote to leave. Islamophobia and Islamophobic conspiracist beliefs also mediated the effects of perceived threat from Muslims on voting intentions. Other variables acted as antecedents of perceived threat or Islamophobic conspiracy narratives. These findings highlight the role that identity-based cognitions may have played in shaping voting intentions for the UK EU referendum.     

Direct remembering,mediated remembering,and atypical forgetting functions

Atypical forgetting functions have been demonstrated in several recent studies of delayed matching to sample, in which experimental conditions are altered partway through the retention interval. The forgetting functions are atypical in that accuracy or discriminability is not always a negatively accelerated monotonic function of increasing retention interval duration, but may increase at later times in the retention interval. Atypical forgetting functions reflect changes in levels of discrimination. A switch from a lower level to a higher level of discrimination, or vice versa, can occur at any time in the retention interval. The behavioral theories of remembering proposed by Nevin, Davison, Odum, and Shahan (2007), and White and Brown (2014), offer quantitative predictions of forgetting functions that differ in intercept or slope. Both theories are able to account for atypical forgetting functions, by assuming time‐independent changes in the mediating effect of attending to sample and comparison stimuli (in Nevin et al.'s model) or in the direct effect of the context of reinforcement of the conditional discrimination (in White & Brown's model). Despite differences in their main assumptions, the theories have an edge over any theory that assumes that forgetting is time‐dependent.     

Understanding the prevalence and correlates of implicit theories of weight in the United States: Insights from a nationally representative sample

Objectives: The primary aim of this research is to understand how mindsets about weight controllability in the United States relate to population health. We examined the distribution of people’s implicit theories of weight, from an incremental (controllable) to an entity (not controllable) mindset, in a nationally representative sample, as well as their relation to: sociodemographic factors, beliefs about behaviour and genetics as causes of obesity and engagement in weight management-relevant behaviours.

Methods: We report data from the National Cancer Institute’s Health Information National Trends Survey 4.

Results: A majority of respondents endorsed an incremental mindset of body weight, but endorsement of this mindset was stronger among younger, white respondents, and those with a higher income and more educational attainment. A stronger incremental mindset was related to stronger behaviour and weaker genetic causal beliefs about obesity, as well as a tendency to report increased engagement in weight management-relevant behaviours.

Conclusions: Our research provides evidence that although incremental mindsets are more common overall and associated with engagement in health behaviours that can contribute to or detract from population health, incremental mindsets are less common among individuals from more marginalised groups.     

Our Followers Are Lions,Theirs Are Sheep: How Social Identity Shapes Theories About Followership and Social Influence

Two studies examine how self‐categorization theory can be used to refine our understanding of people's implicit theories about followership and social influence. Results from Study 1 show that perceivers regard followers of a group they themselves identify strongly with (rather than not at all) to be more representative of the prototype of effective followers (displaying enthusiasm, industry, good citizenship) and to be less representative of the antiprototype of effective followers (displaying conformity, incompetence, and insubordination). Results are replicated in a second experiment in which we compare the views of those self‐categorizing as either Republican or Democrat responding to followers of the Republican and Democratic Party. Results of Study 2 replicate those of Study 1 and also reveal qualitative differences in the preferred influence strategy for dealing with followers. Specifically, respondents seek to engage in persuasion when trying to change the behavior of ingroup followers, while resorting to coercion when trying to change the behavior of outgroup followers. Our results are the first to provide evidence that perceivers' theories about what followers are like and how they are influenced most effectively are structured by perceivers' identification (and dis‐identification) with the particular groups that leaders are championing.     

Are Teachers' Implicit Theories of Creativity Related to the Recognition of Their Students' Creativity?

We examine the structure of implicit theories of creativity among Polish high schools teachers and the role those theories play for the accuracy of teachers' assessment of their students' creativity. Latent class analysis revealed the existence of four classes of teachers, whose perception of a creative student differed: two of these classes defined a creative student incoherently with the existing theories of creativity, and the other two classes did that in accordance with Kirton's (1976) theory of creativity styles, that is, as adaptors or innovators. Teachers who perceived a creative student as an adaptor tended to more accurately assess the creativity of females, whereas teachers perceiving a creative student as an innovator more accurately assessed the creativity of males. We discuss the theoretical and practical consequences of these findings.     

内隐人格观对他人知觉的影响

以大学生为被试,采用投射测验法分离出两类不同性质的内隐人格观,然后通过效价匹配实验和错觉关联实验,初步探讨了内隐人格观对他人知觉的信息加工模式的影响。研究结果表明:(1)跨性格、能力等不同人格属性有共通一致的内隐观;(2)固存观的反面就是渐变观,它们是同一维度的两极;(3)与渐变观者相比,固存观者更易以一种评价性方式知觉他人信息;同时,渐变观者不像固存观者那样对他人特质作出静态判断,而是集中注意力于理解他人行为发生的动态过程。     

Ideology,inquiry, and antiquity: a critical notice of Lloyd's The Ideals of Inquiry: An Ancient History

A discussion of Lloyd's Tarner Lectures at Trinity College. The importance of Lloyd's previous scholarship is characterized and these sweeping, erudite lectures are placed in the context of that scholarship. In the broadest terms, the lectures are a call to culturally and historically comparative study of human reasoning. At their heart is a comparative history of scientific theorizing from the ancients through to modern science. Lloyd rejects the positivist picture, and the view of modern and ancient science as discontinuous; he urges scholars to undertake comparative work on the ancient sciences in different traditions. This critical notice evaluates Lloyd's view and raises several questions for further reflection.     

An essentialism perspective on intercultural processes

Essentialist theories are the beliefs that there are immutable essences underlying observed differences between social groups (e.g. racial group, cultural group). This paper reviews the intergroup dynamics and intrapersonal processes associated with essentialism. It also explores the interplay between the two. By explicating the intricate relationship between these psychological processes, the current paper aims to advance our understanding of intergroup relations and identify their implications for the study of multiculturalism. We posit that although the commonly observed negative intergroup outcomes, such as prejudices and biases, can be the byproducts of basic cognitive processes associated with essentialist theories, the social power dynamics in a given society also play important roles in shaping the relationships between essentialism and intergroup outcomes. We then discuss the implications of this understanding to our increasingly multicultural world.     

Do People Use Their Implicit Theories of Creativity as General Theories?

This study examines whether people use the general implicit theories of creativity or not when applying them to themselves and others. On the basis of the actor–observer asymmetry theory, the authors propose that conception of creativity would be differently constructed depending on the targets of attention: general, self, and other. Three studies attempted to examine this hypothesis. In the preliminary study, a measure was developed to assess the characteristics that describe general creativity. In Study 1, exploratory and confirmatory factor analyses found the conceptual factors of general creativity. In Study 2, the common and specific factors of general, self, and others’ creativity concepts were compared through invariance tests. As a result, it was revealed that the invariance test failed, which means that the general conception of creativity may not be applicable to monitor self and others’ creativity in a consistent way. Implications and limitations of this study are discussed at the end of the study.
