Are Individuals with Schizophrenia or Schizotypy More Creative? Evidence from Multiple Tests of Creative Potential

Schizophrenia and schizotypy have been often associated with above average creativity; however, empirical studies on the relationship between schizophrenia spectrum disorders and enhanced creativity generated inconsistent results. This research investigates if the association between schizophrenia spectrum disorders and creative potential levels is dependent upon which cognitive processes are examined during administered tests of creative potential. Our study examined 117 participants stratified into the following three subgroups: (a) 39 psychometrically determined low-schizotypal individuals, (b) 35 psychometrically determined high-schizotypal individuals, and (c) 43 patients with schizophrenia. Each participant completed 2 divergent thinking (DT) tasks, 2 convergent thinking (CT) tasks, and 2 creative tasks that combine both DT and CT processes. The data suggest that Group C had typical abilities in the DT, CT, and the combined creative thinking tasks; however, the group as a whole had intact originality during the Figural Completion (DT task) and the Tangram Construction (combined task). Notably, Group B showed significant advantages in both verbal and figural DT tasks. Group A and Group B demonstrated no significant differences in the creative thinking processes of CT; however, both groups outperformed Group C in these tasks.     

记忆暗示感受性的双加工机制研究

该研究使用延迟的提取错误范式和R/K/G范式相结合的方法,从编码、误导和提取这三个加工阶段中重要影响因素对记忆暗示感受性产生的交互效应出发,深入考查了记忆暗示感受性产生过程中动态的自动加工与控制加工成分贡献。结果发现:(1)相比无意加工,编码阶段的有意加工更有利于记忆暗示感受性的产生。(2)当个体在编码阶段进行有意加工时,时间压力干扰能发挥其效应,明显提高了其记忆暗示感受性。(3)浅加工编码、时间压力条件下的记忆暗示感受性包含更多的自动加工成分;深加工编码条件下的记忆暗示感受性包含更多的控制加工成分。     

组织不公平与反生产行为的关系

本文以118名企业员工为被试,以自编实验材料和量表为研究工具,探讨组织不公平与反生产行为之间的关系,并考察了权力距离对组织不公平与反生产行为关系的调节作用。结果发现:当被试面对组织不公平情境时,倾向于实施反生产行为;组织不公平情境下,低权力距离组被试在反生产行为得分上显著高于高权力距离组个体,而在中性情境下,两组被试得分差异不显著,即权力距离在组织不公平与反生产行为之间起负向调节作用。由于反生产行为的产生常与组织不公平相关,因此本研究结果将有助于我们更好地理解反生产行为产生的原因,并从心理学角度帮助组织管理者制定减少反生产行为发生的措施。     

公共物品两难中相互依赖关系对合作行为的影响

本文关注初始关系建立过程中互动双方相互依赖关系对个体合作行为的影响,认为情境中表征个体间相互依赖关系的线索会对激活被试在情境中的社会动机并影响被试的信任信念,进而影响互动双方的合作行为。操作互动双方问基于互动制约的相互依赖和基于利益共同的相互依赖,模拟高相互依赖和低相互依赖关系情境。结果表明：①不同的相互依赖关系能够激活不同的社会动机和信任信念;②不同的相互依赖关系中,被试的合作行为有显著差异;③在特定的相互依赖关系中,被试的合作行为与其本身的信任倾向无显著相关;④特定相互依赖关系下被试的社会动机带有策略性,信任信念对被试合作行为的预测能力较强。     

视觉工作记忆中基于客体的存储机制：来自ERPs的证据

该研究以简单形状和颜色构成的客体为材料,采用延迟匹配范式,通过记录事件相关电位,以反映工作记忆表征与知觉输入间冲突的N270为指标,就视觉工作记忆中的客体存储机制进行了探讨。结果发现,无关维度特征变化与目标维度特征变化均可诱发N270。该结果表明,视觉工作记忆对客体目标特征进行存储时,无关特征亦自动得到选择加工,支持基于客体的存储说。

Small and large number processing in infants and toddlers with Williams syndrome

Previous studies have suggested that typically developing 6‐month‐old infants are able to discriminate between small and large numerosities. However, discrimination between small numerosities in young infants is only possible when variables continuous with number (e.g. area or circumference) are confounded. In contrast, large number discrimination is successful even when variables continuous with number are systematically controlled for. These findings suggest the existence of different systems underlying small and large number processing in infancy. How do these develop in atypical syndromes? Williams syndrome (WS) is a rare neurocognitive developmental disorder in which numerical cognition has been found to be impaired in older children and adults. Do impairments of number processing have their origins in infancy? Here this question is investigated by testing the small and large number discrimination abilities of infants and toddlers with WS. While infants with WS were able to discriminate between 2 and 3 elements when total area was confounded with numerosity, the same infants did not discriminate between 8 and 16 elements, when number was not confounded with continuous variables. These findings suggest that a system for tracking the features of small numbers of object (object‐file representation) may be functional in WS, while large number discrimination is impaired from an early age onwards. Finally, we argue that individual differences in large number processing in infancy are more likely than small number processing to be predictive of later development of numerical cognition.     

Predicting Marital Satisfaction From Self,Partner, and Couple Characteristics: Is It Me,You, or Us?

Past research on the link between personal characteristics and marital satisfaction has taken either an individual or a dyadic approach. The individual approach examines how self and/or partner characteristics are associated with satisfaction, whereas the dyadic approach focuses on couple characteristics such as couple similarity. The current research was designed to integrate both approaches. A modified Actor-Partner Interdependence Model (Kashy & Kenny, 2000) was proposed to test simultaneously the contributions of self characteristics, partner characteristics, and two types of couple similarity (level similarity measured by the absolute difference score and shape similarity measured by the profile correlation) in predicting husbands' and wives' marital satisfaction. This model was tested by structural equation modeling in two large, nationally representative, urban samples (N=536 and 537 couples) from China. The results were largely replicated across four personality domains and two value domains, suggesting that all predictors tended to make independent contributions to satisfaction except the absolute difference score.     

Depth of phonological recoding in short-term memory

In testing the hypothesis that surface phonetic form is included in short-term memory (STM) representation, the tone sandhi phenomenon in Mandarin Chinese was exploited, and, as a prerequisite, the hypothesis that tonal similarity affects STM of verbal material in a tone language was also tested. In Experiment 1, subjects recalled visually presented sequences of seven monosyllabic Chinese morphemes having either the same tone or different tones. More errors were made on the monotonal sequences than on the multitonal sequences, confirming the effect of tonal similarity on STM. In Experiment 2, subjects recalled visually presented sequences of disyllabic nonsense words. The sequences were designed in such a way that half of them were subject to the tone sandhi rule in Mandarin Chinese, whereas the other half were not. The consequence of applying the tone sandhi rule, as designed, was to make all the first characters in the sequences identical in pronunciation, thus creating potential phonological confusion. More errors, indeed, occurred on the sequences subject to the tone sandhi rule than on those not subject to it, indicating the existence of a surface phonetic representation in STM. The findings in this study provide further insight into the phonological mechanism of STM. Different accounts for this mechanism are also discussed in the light of the new findings.
