不同年级学生自然阅读过程信息加工活动特点研究

探讨不同年级学生自然阅读过程的信息加工活动特点,包括两个实验。实验１结果表明,低年级学生自然阅读后再复述文章时需要重读原文的时间比高年级学生要多,据此初步推知,低年级学生自然阅读过程可能主要是单一的语言解码信息加工活动,高年级学生自然阅读过程可能同时进行了语言解码与组织连贯的信息加工活动,以后者为主。实验２比较不同年级的学生在自然阅读、理解任务阅读与记忆任务阅读三种情况下对文章信息保持的效果,结果     

任务无关情绪刺激对工作记忆信息更新的影响:来自ERP的证据

任务无关的情绪刺激如何对工作记忆的信息更新过程产生影响还不清楚。本研究采用情绪N-back任务,结合事件相关电位技术调查情绪对工作记忆信息更新的影响。ERP结果显示,在0-back任务中,负性分心物诱发的P3显著小于中性分心物,表明其干扰了工作记忆信息更新过程;而在2-back任务中,负性分心物诱发的P3与中性分心物没有显著差异,表明其未对信息更新表现出干扰效应。该结果支持了情绪与认知加工的双竞争模型。     

突发公共卫生事件中舆论性信息弱势群体的伦理问题

突发公共卫生事件发生后,为了避免疾病扩散,通过流行病学调查得到的患者信息需进行公布,其中与私行私德有关之处在公众围观中可能被放大评判,话语权不足的患者成为舆论中信息弱势群体。这一状况会导致公私边界不明晰,患者私行入公域;道德评价成为情绪宣泄,负面后果无人负责;以道德为名造成撕裂,消解舆论的监督作用等负面后果。要解决这些伦理问题,需要把握适宜的伦理距离,树立距离伦理意识;依照分布式道德行为措施追责,发挥网络平台道德促进者作用;同时增强公共卫生沟通机制中的伦理因素,推进规范化管理。

     

直觉和分析在不同信息获取与呈现方式下对多特征目标判断质量的影响

采用多特征目标判断任务,考察了不同信息获取方式与信息呈现方式条件下,直觉和分析思维模式对判断质量的影响。结果发现：（1）在多特征目标判断任务中,直觉思维比分析思维更有效;（2）直觉型决策者运用直觉思维的判断质量比感觉型决策者更高;（3）归类组块的信息呈现方式能够有效提升决策者运用直觉思维的判断质量;（4）思维模式、信息获取方式与信息呈现方式对多特征目标的判断质量存在三阶交互作用,归类组块的信息呈现方式使直觉型决策者运用直觉思维的判断质量最高,而运用分析思维的判断质量低于感觉型决策者;归类组块排列信息时,直觉型决策者运用分析思维的判断质量低于信息随机排列时的水平。     

南北朝象数易学发展特点述略

南朝郑、王易学并立,北朝象数易学占主导,但后期也呈现儒玄并融的趋势．《易传《》和汉代易学创造出来的象数成果得到南北朝易学家的继承,南朝易学家对象数易学中的形式主义学风给予了批判,并呈现出本体论思维与易学象数相结合的思想萌芽．象数易学受到佛教缘起性空理论的批判,但南北朝佛教仍利用易学象数来说明现象世界．在南北朝道教养生理论中,象数易学得到了丰富和发展．在南北朝的宗教风气下,象数易学占验派沦为方伎．     

Teaching mands for information using ‘when’ to children with autism

Previous research has evaluated contrived motivating operations to teach mands for information. However, literature evaluating acquisition of the mand when? is comparatively limited. As an extension of Shillingsburg, Bowen, Valentino, & Pierce (2014), we taught three children with autism to engage in mands for information using when under alternating conditions in which a contrived establishing operation was present (EOP ) or absent (EOA ). Following training with a constant prompt delay, all participants acquired the mand for information and demonstrated correct use of the provided information and a decrease in inappropriate attempts to access restricted items.     

CAT选题策略分类概述

选题是计算机化自适应测验（CAT）测试过程的关键环节,选题策略的目标是要达到较高的测量精度,同时也实现试题曝光率控制及其他测验目标的实现.本文根据选题策略的基本原理和衍生发展,将众多CAT选题策略分为五大选题策略系列：Fisher函数系列、K-LI函数系列、α分层系列、贝叶斯系列、b匹配系列;并根据测验目标（测验精度、试题曝光率控制、内容平衡、多条件约束）对这些选题策略进行了细分,并对CAT选题策略的选择思路进行归纳.     

Situational information and the design of representative learning tasks: What impact does a scoreboard have on expert taekwondo fighters' behaviour and affective-cognitive responses?

Designing representative learning tasks is one means to enhance sports practice. Recent work has highlighted how the presence of situational information could help the design of these tasks by shaping intentions and enhancing the affective demands of practice, however this has yet to be empirically tested. This study tested this hypothesis by manipulating the presence of a scoreboard featuring time and score situational information as expert taekwondo athletes fought in practice. Nine taekwondo fighters fought with and without situational information in a counterbalanced order. Behaviour was assessed by tracking fighters' location coordinates to assess fighter-fighter dyad coordination and through notational analysis of attacking actions. Affect and cognition were assessed with mixed-methods that included perceptual scales measuring anxiety, arousal, mental effort, score perception, and post-fight video-facilitated confrontational interviews to explore how conditions differed. The results revealed that the presence of the situational information had significant effects on taekwondo players. When present, fighters reported greater cognitive anxiety (d = 0.39, p < 0.05), somatic anxiety (d = 1.11, p < 0.05) and emotion intensity (d = 0.33, p < 0.05). The enhanced affective demands were associated with behaviour changes that included fighters preferring to spend time at closer distances (d = 0.25, p < 0.05), and more predictable technique selection (d = 1.04, p < 0.05). Qualitative data supported these findings. Players also reported their intentions were coupled to the context of scoreboard. This study reveals that situational information changes the affective and behavioural demands of practice to be more like competition. Further, situational sampling affords performers the opportunity to practice attuning to the relevant affordances for a specific context.     

进化心理学对心理素质结构研究的整合与重构——以学生心理素质结构研究为例

传统的心理素质结构研究模式不经济,研究结果出现纵向断裂横向分裂的趋势.从进化心理学的视角来看,心理素质结构的最终功能均指向个体的适应性,其形成是与周围环境不断排斥和融合的过程.建构的心理素质结构融合模型能在一定程度上解决传统研究模式的弊端,并建议今后的研究应以分析人为主导转而分析人及其所处的文化环境并重,进而引导人的心理素质结构的不断发展.     

语义信息在大小数量表征中的作用

本研究采用注意瞬脱实验范式探讨了语义信息在数量表征中的作用。结果发现：（1）在双任务方式中,字母辨认任务对大数（5及以上）的辨认产生干扰,但不影响小数（4及以下）的辨认绩效;（2）数量表征在视野上出现差异性,表现为在小数辨认时,左侧视野呈现绩效高于右侧;大数辨认正好相反,即右侧视野呈现高于左侧。结果表明,语义信息在表征小数和大数中的作用不同：小数的表征无需语言参与;而大数则更多地涉及语义信息,可能需语音回路中无声复述机制的参与。
