Priming reveals differential coding of symbolic and non-symbolic quantities

Number processing is characterized by the distance and the size effect, but symbolic numbers exhibit smaller effects than non-symbolic numerosities. The difference between symbolic and non-symbolic processing can either be explained by a different kind of underlying representation or by parametric differences within the same type of underlying representation. We performed a primed naming study to investigate this issue. Prime and target format were manipulated (digits or collections of dots) as well as the numerical distance between prime and target value. Qualitatively different priming patterns were observed for the two formats, showing that the underlying representations differed in kind: Digits activated mental number representations of the place coding type, while collections of dots activated number representations of the summation coding type.     

The tripartite model for assessing symptoms of anxiety and depression: psychometrics of the Dutch version of the mood and anxiety symptoms questionnaire

AIM: The tripartite model conceptualizes symptoms of depression and anxiety in three groups: low positive affect and anhedonia, which is specific to depression, somatic arousal, which is unique to anxiety, and nonspecific general distress. The Mood and Anxiety Symptoms Questionnaire (MASQ) was developed to measure these symptom domains. This study reports on the psychometric properties of the Dutch translation of the MASQ. METHOD: The questionnaire was completed by a population-based sample and by patients with anxiety and/or mood disorders. Scores of these respondent groups were compared to assess the discriminant validity of the MASQ and evaluate the appropriateness of the tripartite model. RESULTS: The psychometric properties of the translated MASQ were highly satisfactory. In accordance with the model, we found the MASQ to comprise three main scales, which discriminate well between subgroups of patients with mood and anxiety disorders. DISCUSSION: Overall, like the English version the Dutch translation of the instrument appears to be a reliable and valid measure of symptoms of depression and anxiety, conceptualized as comprising three groups of symptoms. The Dutch MASQ is better able to distinguish unique aspects of mood and anxiety disorders than other self-report instruments.     

A Lighthouse In The Desert? Evaluating The Effects Of Creativity Training On Employee Innovation

The contribution of three different creativity training programmes to employees' workplace idea generation and implementation was evaluated. The research was conducted within a government organization, where 191 employees (a mixture of participants and non‐participants in creativity training) were surveyed. Analyses showed that creativity training participants in one type of course only were more likely to generate ideas back at work and that this relationship was mediated by their creative ability and motivation to innovate. However, in terms of later implementation of those ideas, the environmental factors of management support and divisional climate were much more strongly related than the creativity training.     

Completed vs. interrupted priming: Reduced accessibility from post-fulfillment inhibition

We conceptualized an interrupted priming task as a state of an unfulfilled goal and a completed priming task as a post-fulfillment state. The accessibility of a primed construct was measured with both lexical decision and impression formation procedures. Lexical decisions showed enhanced accessibility of prime-related constructs after interrupted priming and reduced accessibility of the prime-related construct after completed priming. Replicating previous findings [Martin, L. L. (1986). Set/reset: Use and disuse of concepts in impression formation. Journal of Personality and Social Psychology, 51, 493-504], an ambiguous target was assimilated to the primed construct after interrupted priming, and was contrasted away from the primed construct after completed priming. Together, these results suggest that task fulfillment instigates inhibition of accessible constructs, in addition to (or instead of) a process of suppressing accessible constructs upon encountering a new target. These findings demonstrate how motivation can affect accessibility through inhibition as well as through suppression.     

The mere acceptance effect: Can it influence responses on racial Implicit Association Tests?

The Implicit Association Test (IAT) is designed to measure the strength of mental association between each of a pair of target categories (e.g., Black vs. White) and each of a pair of attributes (e.g., negative vs. positive). Recent work on the mere acceptance effect shows that, if one of the categories is the focus of attention, then an apparent preference for the focal category can emerge on the IAT, even when no such preference actually exists. It has been suggested that mere acceptance could influence responding on names-based racial IATs, perhaps leading to an exaggeration of anti-Black/pro-White bias. Whether such IATs can be influenced by a mere acceptance effect is unknown, though. By manipulating whether “Black” or “White” was the focal category on a names-based racial IAT, the present studies addressed this very issue. The results were consistent with the operation of mere acceptance effects, but not effects large enough to fully explain the appearance of bias on the IAT.     

Bicultural mind, self-construal, and self- and mother-reference effects: Consequences of cultural priming on recognition memory

Two experiments showed that American (vs. Chinese) culture priming influences Beijing Chinese undergraduates’ self-construal and its attendant memory strategies. Following American culture priming (vs. Chinese culture priming or control), the participants used relatively more independent self-statements and fewer interdependent self-statements to describe the self (Experiment 1). They also performed more poorly in a delayed recognition test if they had encoded the study materials (personality adjectives) with reference to the mother (Experiment 2). These results demonstrate the activation effect of culture on self-construal and its attendant memory processes. The results also show that biculturals can access different cultural conceptions of the self and change cognitive strategies flexibly in response to cues of changing cultural demands in the immediate context.     

归纳推理中的属性中心性效应

通过三个实验研究了属性的中心性程度对归纳推理的影响,结果表明,在归纳推理中存在属性中心性效应,中心属性比其他属性（次中心属性、再次中心属性）更能影响归纳推理。但属性中心性效应的出现受到了前提对象和结论对象相似性程度的制约,当前提对象和结论对象的相似程度高时,中心属性比其他属性更能影响归纳推理;随着相似性水平的降低,中心属性的归纳推理力度越来越弱,而次中心属性、再次中心属性的归纳推理力度则会依次表现出越来越强的趋势,到最后当前提对象和结论对象的属性完全不相似时,最次中心属性的归纳推理力度达到最高水平,而中心属性的归纳推理力度则降低到最低水平。由于再次中心属性的归纳推理力度的最高水平没有显著高于随机水平,而中心属性的归纳推理力度的最低水平却显著低于随机水平,因此,研究者认为,在前提对象和结论对象完全不相似的情况下,被试将确信不能采用中心属性来进行归纳推理的力度判断,而采用猜测的方式选择了肯定可以排除的项目之外的其他项目,这体现了具有不确定的归纳推理活动的过程的典型特征     

Working harder with the out-group: The impact of social category diversity on motivation gains

This paper examines the influence that social category diversity (i.e., working with an in-group or out-group member) has on individual levels of motivation. The results of two experiments provide evidence that individuals increase their effort more when being outperformed by an out-group instead of an in-group member (Experiment 1), but only when the potential for social comparison is present (Experiment 2). We discuss the implications of this research for understanding how and why social category diversity may impact individual levels of motivation.     

从对框架效应的分析看风险决策的神经基础

对风险决策的研究近年来一直是微观经济学和心理学的热门,但是从传统的决策理论到主张有限理性的预期理论大多是对决策行为的研究,决策的心理机制一直是无法解释的黑箱子。令人兴奋的是近几年来神经科学家及其他领域的学者开始用先进的神经心理学的方法来研究风险决策,试图理解神经过程调节风险决策行为的方式。文章从分析违背“不变性”原则的框架效应入手,从正反框架、确定选择和风险选择、风险规避和风险寻求、高估小概率事件几个方面,全面分析风险决策可能的神经基础。在总结已有研究的基础上提出了把风险决策研究扩展到不确定决策,把风险决策中的一次决策研究扩展到多次决策的研究思路     

数字的空间特性

当要求被试对数字进行奇偶判断时,左手对小数的反应较快,而右手对大数的反应较快,该现象被称为空间数字反应编码联合效应（SNARC效应）。大量研究证实了SNARC效应的存在,该效应表明人类对数字的加工受空间表征和空间注意的影响。该文系统地回顾了SNARC效应存在及其发生阶段的证据,对比了Simon效应与SNARC效应,最后尝试着从空间注意的角度挖掘数字和空间的本质联
