学前儿童的现实性监测:即时和延时测验

考察了4至5岁儿童的现实性监测在延时0天、3天和7天条件下的成绩。结果发现:对真实动作的源混淆更多地发生在延时3-7天,而对想象动作的源混淆更多地发生在0-3天,且对想象动作的现实性监测比对真实动作的现实性监测更早达到随机水平。这表明事件在现实性监测的时间效应中存在不同的特点。     

Open field habituation learning is improved by nicotine and attenuated by mecamylamine administered posttrial into the nucleus accumbens

Using the paradigm of habituation learning in the open field, we tested the effects of unilateral microinjections of the agonist nicotine (8.0, 40.0, and 80.0 microg) and the nicotine receptor antagonist mecamylamine (0.1, 1.0, 10.0 microg) into the core of the nucleus accumbens. When injected posttrial, that is, immediately after the first exposure to the open field, nicotine dose-dependently enhanced behavioral habituation during the test on the following day, indicating a facilitation of memory, whereas mecamylamine impaired habituation at the highest dose, but not at the two lower doses. When injected 5 h after the learning trial, nicotine (40 microg) and mecamylamine (10 microg) impaired habituation on the subsequent day. A control experiment did not provide evidence for possible proactive effects of mecamylamine. These findings are discussed with respect to the possible behavioral functions of cholinergic, and especially nicotinic, mechanisms in the nucleus accumbens. They may also be relevant for understanding cholinergic-linked psychopathologies such as Alzheimer's disease, since the nucleus accumbens is one of the sites where cholinergic neurons are lost in this neurodegenerative disease.     

Influence of Social Perception and Social Monitoring on Structural Priming

Although structural priming has been considered to be an independent cognitive process, recent evidence suggests that structural priming is modulated by sociocognitive factors such as social perception; speakers are more likely to mimic the sentence structure of a socially desirable interlocutor than the structure of a less desirable interlocutor. This study aims to further address the role of sociocognitive factors in language use by investigating how individual differences in social perception and tendency to align with others (i.e., social monitoring) modulate same‐verb structural priming. In particular, we investigate how likely students are to repeat a sentence structure of a teacher depending on their perception of the teacher and their social monitoring tendency. Our results demonstrate that students’ tendency to imitate a sentence structure of the teacher is positively influenced by their perception of the teacher but negatively by social monitoring. We suggest that the effects may be accounted for in terms of their influence on attention and memory encoding.     

The Counseling Center Assessment of Psychological Symptoms Distress Index: A pragmatic exploration of general factors to enhance a multidimensional scale

Objective: The authors attempted to develop and validate a general distress index for a multidimensional psychological symptom/outcome measure used in over 300 college counseling centers with more than 100,000 cases annually: the Counseling Center Assessment of Psychological Symptoms (CCAPS). Method: Four models were compared for fit indices (n = 19,247): the existing first-order factor model (without a general factor), a second-order factor model, a bifactor model, and a single factor or “total score” model. In separate clinical and non-clinical samples, concurrent and divergent validity were examined using several well-established measures of psychological symptoms, as well as two-week test–retest and treatment utilization data. Results: Second-order and bifactor models which captured a single “distress” factor both exhibited good fit to the data relative to the baseline and “total score” model. Validity data indicated that factors adequately measured meaningful clinical onstructs. Conclusion: Both the bifactor and second-order models indicated the presence of a “distress index” comprised items across many of the CCAPS subscales. This distress scale has strong applicability for benchmarking the overall severity and complexity of patients at different centers, and can be used to help identify colleges and universities with areas of clinical strength, which can be studied to improve the field. Clinically, the distress index offers a parsimonious and efficient method for clinicians to monitor patients’ progress through treatment.     

一种测量记忆监测相对准确性的新指标：da

记忆监测的相对准确性是元记忆研究中一个重要内容。研究者采用了各种方法来测量人们记忆监测的判断值对正确项目和错误项目的区分度,例如相关法、信号检测论(SDT)测量法。其中,gamma相关从1984年起一直被广泛用于记忆监测相对准确性的测量。基于SDT的新指标da弥补了gamma相关在实际应用中的不足,并引发了新的研究兴趣。文章对da的提出背景、计算方法和应用前景进行了详细的介绍,对da与其他常用方法在使用中的优势进行了比较。对da的具体应用进行了说明,同时指出了da的使用条件。     

Why and how we should care about the General Data Protection Regulation

Abstract

The General Data Protection Regulation (GDPR) is the new European Union-wide (EU) law on data protection, which is a great step towards more comprehensive and more far-reaching protection of individuals' personal data. In this editorial, we describe why and how we – as researchers within the field of health psychology – should care about the GDPR. In the first part, we explain when the GDPR is applicable, who is accountable for data protection, and what is covered by the notions of personal data and processing. In the second part, we explain aspects of the GDPR that are relevant for researchers within the field of health psychology (e.g., obtaining informed consent, data minimisation, and open science). We focus on questions that researchers may ask themselves in their daily practice. Compliance with the GDPR requires adopting research practices (e.g., data minimisation and anonymization procedures) that are not yet commonly used, but serve the fundamental right to protection of personal data of study participants.     

EDITORIAL

The aim of the present study was to evaluate the usefulness of Barkley’s (1997a) model of inhibition and executive functioning in describing the deficits associated with Attention Deficit Hyperactivity Disorder (ADHD). Besides group differences, the present study addressed the question of independent effects of inhibition and the other executive functions in discriminating between children with ADHD and controls and how well, in terms of sensitivity and specificity, these measures can classify the children into the correct group. The results showed that children with ADHD differed significantly from controls with regard to measures of inhibition as well as all other executive function measures, except repetition of hand movements. In logistic regression models, three different measures tapping inhibition, working memory and emotion regulation were shown to be significant independent predictors of group membership. The sensitivity for these three variables as a set was 76.2, the specificity was 90.5, with a total of 86% of the sample correctly classified. When excluding the parental rating of emotion regulation, the overall classification rate decreased some, but was still relatively high in comparison with previous studies within this area of research.     

学习判断与学习时间分配的关系

学习判断与学习时间分配的关系是元认知领域的重要问题, 对学习判断的研究在于使个体了解自己的学习和记忆活动, 从而有效控制学习过程, 合理分配学习时间, 这是元记忆监测影响控制的典型例子。近来有研究者提出学习时间分配不仅表现控制功能, 而且还表现监测功能。于是围绕学习时间的双重功能, 他们提出了元记忆监测与控制至少存在两种关系模型—— MC(监测影响控制)模型和CM(控制影响监测)模型, 后来又提出了两模型相互协同作用的合并动态模型—— 连续波浪型模式和同时发生模型。未来的研究应在继续验证MC模型和完善CM模型的基础上, 尝试检验两模型的合并动态模型。     

有效测量元认知监控的新方法：Mastermind任务分析

元认知监控是元认知的核心成分,而且是内隐程度较高的心理活动。研究采用认知操作法,对经典的Mastermind游戏任务加以改编,结合访谈分析,探讨了适合考察元认知监控的任务难度和有效的元认知监控指标。研究结果发现：（1）对于大学生来说,在游戏4（要求从六种颜色中选出四种正确的颜色,且排列位置也要正确）中当知觉难度最大且又可以经过努力选择策略、根据反馈进行有效选择时,才会在最大程度上激发元认知监控,使得游戏成绩提高;（2）“监测时间”是元认知监测的有效测量指标,而“违背反馈次数”是元认知控制的有效测量指标。     

Parental Awareness and Monitoring of Adolescent Internet Use

This study focused on four aspects of parental monitoring of Internet use by their children: parental supervision, communication and tracking, and adolescent disclosure. Data were obtained from a SAFT (Safety Awareness for Teens Project) national survey of Singapore youths and parents regarding Internet safety at home. Study 1 examined 1,124 adolescents and 1,002 parents; Study 2 examined a subsample of 169 dyads of adolescents and their parents. Frequency of use and engagement in risky Internet behaviors such as visiting inappropriate websites were analysed. The results indicated that parents tend to underestimate adolescents’ engagement in risky Internet behaviors and overestimate the amount of parental monitoring regarding Internet safety that occurs at home. The study suggested that mothers have a better awareness of their adolescents’ Internet use than fathers. The findings were explained in the context of parental monitoring. The results suggest that parental monitoring needs to be reconceptualized and that parents need to improve the communication with their adolescents regarding Internet use.
