Contrasting behavioral looking procedures: a case study on infant speech segmentation

This paper compared three different procedures common in infant speech perception research: a headturn preference procedure (HPP) and a central-fixation (CF) procedure with either automated eye-tracking (CF-ET) or manual coding (CF-M). In theory, such procedures all measure the same underlying speech perception and learning mechanisms and the choice between them should ideally be irrelevant in unveiling infant preference. However, the ManyBabies study (ManyBabies Consortium, 2019), a cross-laboratory collaboration on infants’ preference for child-directed speech, revealed that choice of procedure can modulate effect sizes. Here we examined whether procedure also modulates preference in paradigms that add a learning phase prior to test: a speech segmentation paradigm. Such paradigms are particularly important for studying the learning mechanisms infants can employ for language acquisition. We carried out the same familiarization-then-test experiment with the three different procedures (32 unique infants per procedure). Procedures were compared on various factors, such as overall effect, average looking time and drop-out rate. The key observations are that the HPP yielded a larger familiarity preference, but also reported larger drop-out rates. This raises questions about the generalizability of results. We argue that more collaborative research into different procedures in infant preference experiments is required in order to interpret the variation in infant preferences more accurately.     

“All I remember is the black eye”: A distinctive facial feature harms eyewitness identification

Many crimes occur in which a perpetrator has a distinctive facial feature, such as a tattoo or black eye, but few eyewitness identification (ID) studies have involved such a feature. We conducted an experiment to determine how eyewitness ID performance is impacted by a distinctive facial feature, and how police could deal with this issue. Participants (N = 4,218) studied a target face with or without a black eye, and later viewed a simultaneous photo lineup either containing the target or not. For those who saw a target with a black eye, this feature was either replicated among all lineup members or was removed. The black eye harmed empirical discriminability regardless of replication or removal, which did not differ. However, participants responded more conservatively when the black eye was removed, compared to replication. Lastly, immediate confidence was consistently indicative of accuracy.

作文前计划的时间因素对前计划效应的影响

采用自然实验与实验室实验相结合的方法,通过两个实验探讨作文前计划的时间因素对前计划效应的影响。结果发现,作文方式决定前计划用时,前计划用时影响前计划效应,前计划效应决定前计划形式的作用。这一结果表明,在既有前计划又有外部视觉表征的情况下,前计划本身在前计划时限与前计划形式的关系中起着决定性的作用。因为前计划的存在,使外部视觉表征的作用呈现出更为复杂的情况,从而表现为长时限前计划即充分前计划条件下,外部视觉表征具有重要意义,短时限前计划即不充分前计划条件下,计划比外部视觉表征更具价值。     

任务指向型干预手段对教师教学监控能力的影响

本研究采用任务指向型干预手段,对１０名小学教师教学监控能力进行训练。结果发现：训练不仅提高了教师教学监控能力,而且提高了教师对教学的认知水平,改善了教师 教学行为。     

Cognitive Ability and Personality Predictors of Training Program Skill Acquisition and Job Performance

Two important issues in the training process concern (1) the relative impact of cognitive ability and personality traits on the ability to acquire skills, and (2) whether training skill acquisition predicts subsequent job performance. We used a sample of 9,793 trainees to address these questions and were able to compare those who succeeded on the job with those who did not succeed on the job. We found that some personality factors positively correlate with skill acquisition and that skill acquisition can predict the level of subsequent job performance.     

关于心理表象训练新程序的探讨

本论文对日本新近开发的心理表象训练程序(简称MITP)进行了概要的介绍,并在此基础上分析讨论了有关表象训练的理论问题,认为动觉表象、视觉表象和想象表象的有机结合运用是提高心理训练效果的良好途径,但如何提高练习者的表象机能水平(如表象的清晰准确性、鲜明生动性以及对表象的操作控制能力等)则是表象训练所面临的最大难题。     

中小学生语文阅读理解能力结构及其发展特点研究

本文从实证的角度探讨了中小学生语文阅读理解能力的结构组成及其发展特点。结果认为,被试阅读理解能力的水平主要是受其阅读理解能力结构的发展水平制约,因为即使在同一个年级组里。高水平被试组的阅读理解能力结构也比低水平被试组的阅读理解能力结构更复杂。而阅读理解能力水平的发展一般遵循量的累加与质的飞跃的过程,质的飞跃意味着阅读理解能力结构的发展与分化。     

作文前构思时间分配及其对写作成绩影响的研究

通过3个分实验考察了优差生的作文前构思时间分配及其不同的构思时间分配策略对作文成绩的影响。实验1发现“优生”和“差生”在无时限写作情况下,前者花在构思上的时间更多,并运用了较好的构思策略;实验2发现“优生”和“差生在限时写作情况下,在构思时间上没有显著的差异,但他们在构思策略上仍表现出差异;实验3发现长时限构思比短时限构思能够带来更好的文本质量。作者对写作前构思的计划和管理,可能是提高作文质量的自我调控策略之一。     

组织研究中的多层面问题

多层面理论（multilevel theory）已成为组织研究中的一个新范式,它可以研究微观和宏观二者之间的交互作用。为了给组织研究者提供一个思考和决策框架,文章在简要回顾多层面研究的来源后,介绍了3种集体层面的结构、集体层面结构的5种“构成模型”（composition model）、以及1个判断框架,并介绍了多层面研究中常用的4个论证指标（rwg、ICC（1）、ICC（2）、WABAI）的算法和区别,最后对常用的3种分析方法（WABA：within-and-between-analysis、HLM：hierarchical linear modeling、CLOP：cross-level operator）进行了简单介绍和比较。
