Anomalous experiences and schizotypy: which comes first? The Hermit Crab syndrome hypothesis

This study confirms findings of previous research as they state that some triggering events or anomalous experiences can give rise to a disruption of cognitive processes and emotional changes in a predisposed person. Furthermore, our research states that the cognitive process and change of world view (paradigm shift (PS)) accompanying some paranormal experiences (PEs) could facilitate the development of a schizotypal personality structure. For the purposes of this study, 675 young people aged between 13 and 25 years old (M?=?16.8, SD?=?1.9) completed the Schizotypal Personality Questionnaire, the Revised and Modified Paranormal Belief Scales, the measurement of eight kinds of PE and a self-reported measurement of change of world view. The results confirm the mediating role of PS between paranormal practices and schizotypy as the cognitive process contributing to symptom formation as well as to symptom maintenance. The said results also confirm the existence of cognitive–emotional stages, also called Hermit Crab syndrome, in the process of the “paranormalisation” of reality.     

基于文本阅读的间接接触也可改善公众对残疾人的态度

以镶嵌残疾人图片的正性行为描述性信息为文本阅读材料,以大学生为被试,采用概念启动范式,考察了健全人对残疾人态度改善的可能性.研究结果表明,阅读残疾人正性行为描述性材料不仅可以降低健全人对残疾人的负性认知评价,而且可以提高其对残疾人的钦佩感和减弱其对残疾人的嫌弃感,同时也可提高健全人对该类人群的积极趋近行为和减弱对该类人群的消极趋近和消极回避行为,从而证明基于文本阅读的间接接触可改善公众对残疾人的负性态度的假设.因此,创造条件鼓励残疾人尽力发挥其积极的社会功能,引导和塑造其身残志不残的品质,有助于改善健全人对该类人群的消极态度.     

Working Memory in Nonsymbolic Approximate Arithmetic Processing: A Dual‐Task Study With Preschoolers

Preschool children have been proven to possess nonsymbolic approximate arithmetic skills before learning how to manipulate symbolic math and thus before any formal math instruction. It has been assumed that nonsymbolic approximate math tasks necessitate the allocation of Working Memory (WM) resources. WM has been consistently shown to be an important predictor of children's math development and achievement. The aim of our study was to uncover the specific role of WM in nonsymbolic approximate math. For this purpose, we conducted a dual‐task study with preschoolers with active phonological, visual, spatial, and central executive interference during the completion of a nonsymbolic approximate addition dot task. With regard to the role of WM, we found a clear performance breakdown in the central executive interference condition. Our findings provide insight into the underlying cognitive processes involved in storing and manipulating nonsymbolic approximate numerosities during early arithmetic.     

Familiar Verbs Are Not Always Easier Than Novel Verbs: How German Pre‐School Children Comprehend Active and Passive Sentences

Many studies show a developmental advantage for transitive sentences with familiar verbs over those with novel verbs. It might be that once familiar verbs become entrenched in particular constructions, they would be more difficult to understand (than would novel verbs) in non‐prototypical constructions. We provide support for this hypothesis investigating German children using a forced‐choice pointing paradigm with reversed agent‐patient roles. We tested active transitive verbs in study 1. The 2‐year olds were better with familiar than novel verbs, while the 2½‐year olds pointed correctly for both. In study 2, we tested passives: 2½‐year olds were significantly below chance for familiar verbs and at chance for novel verbs, supporting the hypothesis that the entrenchment of the familiar verbs in the active transitive voice was interfering with interpreting them in the passive voice construction. The 3½‐year olds were also at chance for novel verbs but above chance with familiar verbs. We interpret this as reflecting a lessening of the verb‐in‐construction entrenchment as the child develops knowledge that particular verbs can occur in a range of constructions. The 4½‐year olds were above chance for both familiar and novel verbs. We discuss our findings in terms of the relative entrenchment of lexical and syntactic information and to interference between them.     

Transdisciplinary Child and Youth Studies: Critical Praxis,Global Perspectives

Drawing on empirical and theoretical literature from across six continents, this Introduction to a special issue of World Futures serves as a prelude to seven articles focused on transdisciplinary child and youth studies. The resulting gestalt builds on the assumption that those engaged in transdisciplinary research and pedagogy are also deeply engaged in the global reform movement currently underway in higher education. As a contribution to this process, we make two key arguments. First, Indigenous epistemologies (defined as traditional integrated knowledge systems drawing on connectedness to the Earth and ontologies of respect for past and future generations) must be fully included within the transdisciplinary canon. Second, we introduce child and youth studies as an inherently transdisciplinary field, one that embraces complex systems analysis along with young people’s participation in research that concerns their well-being.     

真实记忆与虚假记忆中的生命性效应研究

本研究采用DRM范式,探讨了生命性对真实和虚假记忆的影响。实验1使用类别呈现词语强化类别加工,实验2伪随机呈现词语弱化类别加工并进行即时及延时探测。结果发现：（1）当强化类别加工时,生命性和类别对击中率有相类似的促进效应;（2）当弱化类别加工并进行即时探测时,生命性对击中率的促进作用最强;（3）类别效应促进真实记忆和虚假记忆,但生命性效应仅促进了真实记忆,而不影响虚假记忆的产生;（4）在即时与延时探测中均发现类别效应和生命性效应。本研究证明了：（1）生命性效应的作用机制不同于类别效应;（2）生命性效应对真实和虚假记忆的作用机制不同;（3）类别效应和生命性效应的存在时效长达24小时,但是生命性效应的衰退速度较快。     

遮挡范式下运动速度和方向对碰撞时间估计绩效指标的影响

为探索运动速度和方向对碰撞时间（TTC）估计的影响,采用3运动速度×4运动方向的双因素设计开展了实验研究。结果发现,在相对慢速条件下,受试者TTC估计的准确性显著差于相对中速和相对快速条件;仅在相对慢速条件下受试者对竖直方向的TTC估计准确度显著差于水平方向、低估TTC的比例显著高于高估TTC的比例。结果表明,运动速度对TTC估计绩效指标的影响相对较强,运动方向对其影响相对较弱;两个因素的影响存在交互作用。     

反馈对自我欺骗的影响：来自ERP的证据

本研究主要探讨反馈类型和反馈效价对自我欺骗的影响。实验1采用前瞻范式探究不同效价的模糊反馈对自我欺骗的影响, 结果发现, 相比于无答案提示组, 有答案提示组的被试在积极模糊反馈的条件下显著地提高测试2第二阶段的预测分数(自我欺骗的程度加重)。实验2探究不同效价的精确反馈对自我欺骗的影响, 结果发现, 相对于无答案提示组, 有答案提示组的被试在消极精确反馈条件下显著地降低测试2第二阶段的预测分数。实验3采用ERP技术探究反馈类型和反馈效价影响自我欺骗的内在机制, 结果发现, 模糊反馈条件下的自我欺骗诱发较大的P2成分、诱发较小的N1和N400成分; 以及发现自我欺骗在额区的效应较大。总之, 这些研究结果表明可能积极反馈促进个体的自我欺骗产生, 消极反馈削弱个体自我欺骗的产生; 积极模糊反馈能够进一步促进了个体自我欺骗的产生。这些研究结果还表明自我欺骗产生的背后机制可能是自我膨胀。     

启动情绪和呈现方式对错误记忆的影响

采用DRM范式(Deese-Roediger-Mc Dermott paradigm),考察了启动情绪状态下词表项目的呈现方式对错误记忆的影响。结果发现:(1)启动情绪主效应不显著。(2)词表项目的呈现方式主效应显著。(3)启动情绪与呈现方式间存在交互作用。在愉快启动情绪状态下分组呈现的错误再认率明显高于随机呈现条件;当词表项目分组呈现时,三种情绪状态下的错误再认率有显著差异,其中愉快启动情绪下的错误再认率最高,其次是悲伤情绪,最低的为对照组—非启动情绪状态。说明启动的愉快情绪增强了对关键诱饵的连续激活累积效应,从而导致对关键诱饵较高的错误再认率。
