Time keeping and working memory development in early adolescence: A 4-year follow-up

In this longitudinal study, we examined time keeping in relation to working memory (WM) development. School-aged children completed two tasks of WM updating and a time monitoring task in which they indicated the passing of time every 5 min while watching a film. Children completed these tasks first when they were 8 to 12 years old and then 4 years later when they were 12 to 16 years old. Time keeping in early adolescence showed a different pattern of outcome measures than 4 years earlier, with reduced clock checking and increased timing error. However, relative changes in WM development moderated these adverse effects. Adolescents with greater relative gains in WM development were better calibrated than participants with less developing WM functions. We discuss these findings in relation to individual and developmental differences in executive control functions and socioemotionally driven reward seeking.     

Is comprehension necessary for error detection? A conflict-based account of monitoring in speech production

Despite the existence of speech errors, verbal communication is successful because speakers can detect (and correct) their errors. The standard theory of speech-error detection, the perceptual-loop account, posits that the comprehension system monitors production output for errors. Such a comprehension-based monitor, however, cannot explain the double dissociation between comprehension and error-detection ability observed in the aphasic patients. We propose a new theory of speech-error detection which is instead based on the production process itself. The theory borrows from studies of forced-choice-response tasks the notion that error detection is accomplished by monitoring response conflict via a frontal brain structure, such as the anterior cingulate cortex. We adapt this idea to the two-step model of word production, and test the model-derived predictions on a sample of aphasic patients. Our results show a strong correlation between patients’ error-detection ability and the model’s characterization of their production skills, and no significant correlation between error detection and comprehension measures, thus supporting a production-based monitor, generally, and the implemented conflict-based monitor in particular. The successful application of the conflict-based theory to error-detection in linguistic, as well as non-linguistic domains points to a domain-general monitoring system.     

药物安全：不良反应及其监测

药品是疾病治疗的重要手段,如何发挥药品的最大疗效,降低其不良反应,一直是关注的热点问题。近年来,随着新药的不断上市,药物不良反应发生率呈上升趋势。针对这种情况,从如何认识、判定、预防、处理四个方面,对药物不良反应进行了分析,旨在使药物不良反应得到关注,使用药安全、有效。     

儿童程序性元记忆的发展

元记忆包括陈述性元记忆和程序性元记忆。程序性元记忆是对记忆过程的监测和控制。本文从发展的角度对程序性元记忆新近的研究进展进行了回顾。(1)几种记忆监测的发展速度和趋势不尽相同。(2)记忆控制发展较晚。(3)对今后的研究趋势进行了预测。     

来源监测实验中的源记忆测量

来源监测实验既涉及到研究项目探测、来源甄别两种不同的认知加工过程,又涉及到研究反应倾向。当研究目的着眼于测量或比较不同来源源记忆或不同控制变量组在同一来源上的源记忆效果时,把来源甄别和项目探测两种认知过程及反应倾向分解开是十分必要的。通常的测量和分析方法对此收效甚微,多项式加工树模型旨在有效地实现这一目标。     

启发信息对个体顿悟问题解决影响的眼动研究

本研究以火柴棒算式问题为实验材料,采用2(问题类型:问题A、问题B)×2(启发类型:有、无)×2(认知风格:场独立型、场依存型)×5(兴趣区:第一个加数、加号、第二个加数、等号和结果)实验设计,考察顿悟问题解决时个体的眼动差异。结果发现:相对于场依存型个体,场独立型个体能够更有效地利用启发信息来减小表征变换时的心理加工负荷,进而提高加工效率;启发信息促进问题解决者对问题的表征从数值表征转变到符号表征,从而成功地产生了顿悟。     

Learning to calibrate: Providing standards to improve calibration accuracy for different performance levels

This experimental study explores whether feedback in the form of standards helps students in giving more accurate performance estimates not only on current tasks but also on new, similar tasks and whether performance level influences the effect of standards. We provided 122 first‐year psychology students with seven texts that contained key terms. After reading each text, participants recalled the correct definitions of the key terms and estimated the quality of their recall. Half of the participants subsequently received standards and again estimated their own performance. Results showed that providing standards led to better calibration accuracy, both on current tasks and on new, similar tasks, when standards were not available yet. Furthermore, with or without standards, high performers calibrated better than low performers. However, results showed that especially low performers' calibration accuracy benefitted from receiving standards.     

掌握程度和社会性线索对元认知监控的影响

元认知监控中信心判断和再认答案的调整不仅受到个体学习后掌握程度的影响,还会受到社会性线索的影响。本研究通过两个实验,考察了掌握程度和社会性线索对元认知监测和控制的影响。研究发现：第一,掌握程度和社会性线索独立影响元认知监测。第二,掌握程度和社会性线索显著影响元认知控制,并且掌握程度还起到了调节作用。具体来说,掌握程度高时,个体倾向于坚持自己的最初选择,较少受到社会性线索的影响;掌握程度越低,社会性线索的影响越大,个体倾向于使自己的选择与社会性信息保持一致。最后,研究总结了学习任务中掌握程度和社会性线索对元认知监控的影响机制,并提出了未来的研究思路。     

Therapeutic progress and symptom elevation in treating dismissive attachment: A case study

A dismissive or avoidant attachment style can present clinical challenges in psychotherapy as the attachment style may interfere with the development of a constructive therapeutic alliance and impact the level of disclosure, expressions of distress, and risks for premature drop-out. This paper reports a naturalistic case study and offers an in-depth examination of a treatment with a client with dismissive attachment, including a detailed examination of relational interventions and countertransference struggles. Furthermore, this paper considers the notable differences between quantitative scores on a well-validated, practice-based clinical symptom inventory and the qualitative outcomes for this client to offer clinical and research implications in treatment with dismissive attachment.
