Novel Labels Increase Category Coherence,But Only When People Have the Goal to Coordinate

From infancy, we recognize that labels denote category membership and help us to identify the critical features that objects within a category share. Labels not only reflect how we categorize, but also allow us to communicate and share categories with others. Given the special status of labels as markers of category membership, do novel labels (i.e., non‐words) affect the way in which adults select dimensions for categorization in unsupervised settings? Additionally, is the purpose of this effect primarily coordinative (i.e., do labels promote shared understanding of how we categorize objects)? To address this, we conducted two experiments in which participants individually categorized images of mountains with or without novel labels, and with or without a goal of coordination, within a non‐communicative paradigm. People who sorted items with novel labels had more similar categories than people who sorted without labels only when they were told that their categories should make sense to other people, and not otherwise. We argue that sorters' goals determine whether novel labels promote the development of socially coherent categories.     

Are Perfectionism Dimensions Vulnerability Factors for Depressive Symptoms After Controlling for Neuroticism? A Meta‐analysis of 10 Longitudinal Studies

Extensive evidence suggests neuroticism is a higher‐order personality trait that overlaps substantially with perfectionism dimensions and depressive symptoms. Such evidence raises an important question: Which perfectionism dimensions are vulnerability factors for depressive symptoms after controlling for neuroticism? To address this, a meta‐analysis of research testing whether socially prescribed perfectionism, concern over mistakes, doubts about actions, personal standards, perfectionistic attitudes, self‐criticism and self‐oriented perfectionism predict change in depressive symptoms, after controlling for baseline depression and neuroticism, was conducted. A literature search yielded 10 relevant studies (N = 1,758). Meta‐analysis using random‐effects models revealed that all seven perfectionism dimensions had small positive relationships with follow‐up depressive symptoms beyond baseline depression and neuroticism. Perfectionism dimensions appear neither redundant with nor captured by neuroticism. Results lend credence and coherence to theoretical accounts and empirical studies suggesting perfectionism dimensions are part of the premorbid personality of people vulnerable to depressive symptoms.

Fichte's Creuzer review and the transformation of the free will problem

Fichte's early review of C. A. L. Creuzer's neglected and idiosyncratic skeptical book on free will posed a serious challenge to what at the time was emerging as a consensus Kantian position on the role of free choice (Willkür) in the generation of imputable action. Fichte's review was directed as much against Reinhold's important (and only recently published) letter on freedom of the will as it was against Creuzer himself. In the course of his brief review, Fichte suggests an important recasting of the strategy of the Kantian postulates of rational faith; he poses a dilemma for the Reinholdian understanding of the relationship among an autonomous practical will, a free power of choice, and the actions of natural human organisms; and he hints at a radical reappropriation of the rationalist doctrine of pre‐established harmony in re‐orienting the search for a defensible reconstruction of a broadly Kantian position on the problem of free will.     

GENDER DIFFERENCES IN SALARY EXPECTATIONS WHEN CURRENT SALARY INFORMATION IS PROVIDED

It was hypothesized that current gender differences in salary expectations arise from women's lack of accurate salary information. Current salary information was provided for a sample of upcoming university graduates. Contrary to expectations, large gender differences in salary expectations continued in spite of subjects' knowledge of current salary data. Alternative explanations are discussed.     

Self-Explanations: How Students Study and Use Examples in Learning to Solve Problems

The present paper analyzes the self-generated explanations (from talk-aloud protocols) that “Good” and “Poor” students produce while studying worked-out examples of mechanics problems, and their subsequent reliance on examples during problem solving. We find that “Good” students learn with understanding: They generate many explanations which refine and expand the conditions for the action parts of the example solutions, and relate these actions to principles in the text. These self-explanations are guided by accurate monitoring of their own understanding and misunderstanding. Such learning results in example-independent knowledge and in a better understanding of the principles presented in the text. “Poor” students do not generate sufficient self-explanations, monitor their learning inaccurately, and subsequently rely heavily on examples. We then discuss the role of self-explanations in facilitating problem solving, as well as the adequacy of current AI models of explanation-based learning to account for these psychological findings.
