幼儿心理理论表现的任务特异性分析

研究以90名3～5岁幼儿为被试,采用相同材料和标准评估幼儿外表-事实的区分和错误信念认识,考察幼儿表现的任务特异性及材料刺激的影响。结果表明;幼儿的表现仍存在任务特异性,并且实验材料对儿童的外表-事实区分和错误信念认识具有重要影响。在解释这些结果时,特殊领域知识习得观似乎优于表征缺失理论。     

Global and local evaluations of public speaking performance in social anxiety

Differences in the relative use of global and local information (seeing the forest vs. the trees) may explain why people with social anxiety often do not benefit from corrective feedback, even though they pay close attention to details in social situations. In the current study, participants high (n = 43) or low (n = 47) in social anxiety symptoms gave a series of brief speeches, and then self-rated their speaking performance on items reflecting global and local performance indicators (self-assessment) and also received standardized performance feedback from an experimenter. Participants then completed a questionnaire asking how they thought the experimenter would rate their performance based on the feedback provided (experimenter assessment). Participants completed the self- and experimenter assessments again after 3 days, in addition to a measure of postevent processing (repetitive negative thinking) about their speech performance. Results showed that, as hypothesized, the High SA group rated their performance more negatively than the Low SA group. Moreover, the High SA group's ratings of global aspects of their performance became relatively more negative over time, compared to their ratings of local aspects and the Low SA group's ratings. As expected, postevent processing mediated the relationship between social anxiety group status and worsening global performance evaluations. These findings point to a pattern of progressively more negative global evaluations over time for persons high in social anxiety.     

Suspicion in the workplace: Organizational conspiracy theories and work‐related outcomes

Belief in conspiracy theories about societal events is widespread and has important consequences for political, health, and environmental behaviour. Little is known, however, about how conspiracy theorizing affects people's everyday working lives. In the present research, we predicted that belief in conspiracy theories about the workplace would be associated with increased turnover intentions. We further hypothesized that belief in these organizational conspiracy theories would predict decreased organizational commitment and job satisfaction. Finally, we hypothesized that these factors would mediate the relationship between organizational conspiracy theories and turnover intentions. In three studies (one correlational and two experiments, Ns = 209, 119, 202), we found support for these hypotheses. The current studies therefore demonstrate the potentially adverse consequences of conspiracy theorizing for the workplace. We argue that managers and employees should be careful not to dismiss conspiracy theorizing as harmless rumour or gossip.     

Effects of the good behavior game across classroom contexts

The Good Behavior Game (GBG), a well‐researched classroom group contingency, is typically played for brief periods of time, which raises questions about the effects on subsequent contexts. This study used a multiple baseline design and showed that when the GBG was implemented in one context, behavior improved in only that context. Behavior improved in the subsequent activity only when the GBG was implemented.     

Motor Planning Influences the Perceived Timing of Vibrotactile Stimuli in an Amplitude-Dependent Manner

The authors characterized how motor planning influences temporal order judgment (TOJ) tasks. They examined this by applying vibrotactile stimulation during the planning stages of a bimanual arm movement that would bring the arms into a crossed configuration. The authors have previously shown that planning to cross the arms induces a subjective reversal of spatially defined temporal order judgments that evolves over the course of the planning period. It was unclear, however, whether this effect is modulated by the extent to which the arms would be crossed after movement. The authors examined this issue by having participants plan to move to 4 different targets that would leave the arms in crossed configurations of varying extents. The results demonstrate that even though cutaneous stimuli were applied before the movements, if participants were planning to move into a more crossed configuration, performance on the TOJ task worsened depending on where they were in the planning process. This data suggest the brain uses planning signals to predict sensations from impending movements in a context-dependent manner.     

What Kind of Normativity is the Normativity of Grammar?

The overall goal of this article is to show that aesthetics plays a major role in a debate at the very center of philosophy. Drawing on the work of David Bell, the article spells out how Kant and Wittgenstein use reflective judgment, epitomized by a judgment of beauty, as a key in their respective solutions to the rule‐following problem they share. The more specific goal is to offer a Kantian account of semantic normativity as understood by Wittgenstein. The article argues that Wittgenstein's reason for describing language as a collection of language games is to allow for a perspective that shows those games as internally purposive without any extralinguistic purpose. This perspective also allows for that union of the general rule and its particular application in practice that the original paradox of rule‐following is wanting.     

Beliefs do not come in degrees

Philosophers commonly say that beliefs come in degrees (or that beliefs are graded or that there are partial beliefs). Drawing from the literature, I make precise three arguments for this claim: an argument from degrees of confidence, an argument from degrees of firmness, and an argument from natural language. I show that they all fail. I also advance three arguments that beliefs do not come in degrees: an argument from natural language, an argument from intuition, and an argument from the metaphysics of degrees. On the basis of these arguments, I conclude that beliefs do not come in degrees.     

Do you see my growth? Two longitudinal studies on personality development from childhood to young adulthood from multiple perspectives

Personality developmental studies typically rely on single reporter data, while multi-informant studies are rare. In two longitudinal studies, the present investigation examined inter-judge differences in the development of the Big Five personality traits from childhood to young adulthood. Study 1 investigated personality development as judged by the self and parents from age 12 to 17 to 29 (N = 186). Study 2 investigated personality development annually from age 12 to 18 as judged by the self, and both parents and siblings (N = 574). Results showed personality maturation from childhood to young adulthood with disruptions during adolescence. Only parent-reports indicated maturation in adolescents’ negative affectivity (decreases in N), while self-reports indicated maturation in self-regulatory traits (increases in A and C).     

Comparative Optimism and Event Skewness

Comparative judgment biases—wherein a majority of people report being above‐ or below‐average in their abilities, traits, or future events—are a robust phenomenon in psychology. A recent explanation for these biases has focused on people's awareness that many comparative judgment domains form skewed distributions, and, hence, a majority of people can feasibly be above or below average. Indeed, this prior research found that comparative biases for abilities emerged more for skewed (vs. normal) distributions. In the current research, we attempted to (i) conceptually replicate this finding in a comparative likelihood context and (ii) provide evidence of an alternative explanation for the prior results. Replicating prior research, three correlational studies and one experimental study found that event skewness was related to direct comparative likelihood judgments for health events, such that comparative optimism emerged more for events judged or manipulated to come from positively skewed distributions than from negatively skewed distributions. However, event skewness was unrelated to indirect comparisons (absolute self minus absolute other). Moreover, consistent with an egocentric‐processes account, absolute self‐judgments were more predictive of direct comparisons than were absolute other judgments and showed the same association with event skewness as direct comparisons. Implications for explaining and interpreting comparative judgment biases are discussed. Copyright © 2016 John Wiley & Sons, Ltd.
