Relationships between implicit and explicit uncertainty monitoring and mindreading: Evidence from autism spectrum disorder

We examined performance on implicit (non-verbal) and explicit (verbal) uncertainty-monitoring tasks among neurotypical participants and participants with autism, while also testing mindreading abilities in both groups. We found that: (i) performance of autistic participants was unimpaired on the implicit uncertainty-monitoring task, while being significantly impaired on the explicit task; (ii) performance on the explicit task was correlated with performance on mindreading tasks in both groups, whereas performance on the implicit uncertainty-monitoring task was not; and (iii) performance on implicit and explicit uncertainty-monitoring tasks was not correlated. The results support the view that (a) explicit uncertainty-monitoring draws on the same cognitive faculty as mindreading whereas (b) implicit uncertainty-monitoring only test first-order decision making. These findings support the theory that metacognition and mindreading are underpinned by the same meta-representational faculty/resources, and that the implicit uncertainty-monitoring tasks that are frequently used with non-human animals fail to demonstrate the presence of metacognitive abilities.     

Happy but overconfident: positive affect leads to inaccurate metacomprehension

When learning from text, it is important that learners not only comprehend the information provided but also accurately monitor and judge their comprehension, which is known as metacomprehension accuracy. To investigate the role of a learner’s affective state for text comprehension and metacomprehension accuracy, we conducted an experiment with N?=?103 university students in whom we induced positive, negative, or neutral affect. Positive affect resulted in poorer text comprehension than neutral affect. Positive affect also led to overconfident predictions, whereas negative and neutral affect were both associated with quite accurate predictions. Independent of affect, postdictions were rather underconfident. The results suggest that positive affect bears processing disadvantages for achieving deep comprehension and adequate prediction accuracy. Given that postdictions were more accurate, practice tests might represent an effective instructional method to help learners in a positive affective state to accurately judge their text comprehension.     

Examining program quality in early childhood home visiting: From infrastructure to relationships

Although there are many examples of evidence-based early childhood home-visiting programming, the field itself struggles with modest outcomes and variable levels of program effectiveness. This article documents the experience of creating a statewide monitoring system to assess home-visiting program quality and compliance to identified standards, integrating multiple sources of information across different domains of functioning. Monitoring results from 57 programs are summarized, with variable but promising levels of quality. Programs generally report satisfaction and benefit from the process. In addition, the relationship between direct observations of home visits and home-visitor report of their approach to working with families is analyzed. Results suggest significant, albeit small, associations. Although there are trade-offs between comprehensiveness of information gathering and practical application, the use of monitoring findings to support home-visiting programs holds potential for quality improvement.     

工作记忆在监控作业情境意识保持中的作用

本研究通过模拟复杂人机系统的监控作业,考察了长时工作记忆与短时工作记忆在情境意识保持中的作用。研究采用模拟的飞行相撞判断任务,通过考察中断任务对情境意识的影响,分析情境意识在记忆中的存储地点,以及保持时间是否会突破1分钟的限制。本研究选择了心理旋转和算式判断两种中断任务。实验结果表明,在问题回答之前的中断阶段,无论施加心理旋转任务,还是施加算式判断任务,无论中断任务的加工负荷与记忆负荷有多高,熟练被试的情境意识始终保持于较高的水平,并没有因受到中断任务的干扰而出现下降。新手被试的情境意识受到心理旋转任务和算式判断任务的显著影响,而且两种任务的执行速度越快、记忆负荷越大,情绪意识水平就越低。本研究结果说明熟练被试可以利用长时工作记忆存储情境意识,新手被试主要利用短时工作记忆存储情境意识。     

错误相关负电位（ERN）及其理论解释

错误动作发生后,在个体额叶中部可观察到一个明显的负相电位偏移,这称为“错误相关负电位”（error related negativity,ERN）。有研究者提出了“强化学习理论”,认为ERN反映了当前行为结果与预期之间的差异。与此不同的是“冲突监控理论”,认为ERN与反应冲突有关。还有研究者提出了“失匹配理论”,强调实际反应的神经表征（错误反应）与当前任务所要求的反应表征的差异产生了ERN。在阐述ERN的理论解释基础上,对三者之间的关系进行了分析与整合。     

学前儿童的现实性监测对易受暗示性的预测

对学前儿童的现实性监测与易受暗示性发展之间的关系进行了考察.结果表明,在控制了年龄、对事件的初始编码和提取能力后,现实性监测能力可以显著地预测记忆的易受暗示性.那些现实性监测能力较低的儿童更容易接受误信息,相反,那些现实性监测能力较强的儿童,更能抵制误信息的干扰.     

Form effects on the estimation of students' oral reading fluency using DIBELS

This study examined the effects of passage and presentation order on progress monitoring assessments of oral reading fluency in 134 second grade students. The students were randomly assigned to read six one-minute passages in one of six fixed orders over a seven week period. The passages had been developed to be comparable based on readability formulas. Estimates of oral reading fluency varied across the six stories (67.9 to 93.9), but not as a function of presentation order. These passage effects altered the shape of growth trajectories and affected estimates of linear growth rates, but were shown to be removed when forms were equated. Explicit equating is essential to the development of equivalent forms, which can vary in difficulty despite high correlations across forms and apparent equivalence through readability indices.
