邻里环境、父母监控和不良同伴交往对青少年问题行为的影响

父母监控和不良同伴交往是影响青少年问题行为的重要因素,同时这种影响又离不开其所处邻里环境的共同作用。本研究通过对2个区县7所学校47个班2188名初一学生及其家长的问卷调查,探讨了邻里环境指标、父母监控和不良同伴交往影响青少年问题行为的路径。结果发现：（1）邻里犯罪能够直接预测青少年的问题行为;同时,邻里犯罪、邻里凝聚与混乱还能够通过父母监控和不良同伴交往为中介,进而影响青少年问题行为;（2）在纳入邻里环境影响条件下,父母监控与不良同伴交往对于青少年问题行为的影响具有显著的交互作用;随着父母监控的提高,不良同伴交往对青少年问题行为的影响减小;（3）对于男孩而言,邻里犯罪对问题行为、父母监控对问题行为、不良同伴交往对问题行为的预测作用大于女孩。     

词频和运动流畅性对学习判断的影响：多线索整合的视角

本研究探讨基于经验的运动流畅性和基于理论的词频对学习判断的影响以及二者可能存在的相互作用,探讨非分析性加工和分析性加工在元认知监测中的作用模式。结果显示：（1）运动流畅性和词频均会影响JOL;（2）运动流畅性对JOL的影响会因为词频的变化而改变,而在认知负荷条件下,词频对JOL的影响还会因为运动流畅性的变化而不同。研究结果支持JOL中的运动流畅性效应与词频效应,也表明分析性和非分析性加工在JOL中会共同发挥作用。     

Dissociated control as a signature of typological variability in high hypnotic suggestibility

This study tested the prediction that dissociative tendencies modulate the impact of a hypnotic induction on cognitive control in different subtypes of highly suggestible individuals. Low suggestible (LS), low dissociative highly suggestible (LDHS), and high dissociative highly suggestible (HDHS) participants completed the Stroop color-naming task in control and hypnosis conditions. The magnitude of conflict adaptation (faster response times on incongruent trials preceded by an incongruent trial than those preceded by a congruent trial) was used as a measure of cognitive control. LS and LDHS participants displayed marginally superior up-regulation of cognitive control following a hypnotic induction, whereas HDHS participants’ performance declined. These findings indicate that dissociative tendencies modulate the influence of a hypnotic induction on cognitive control in high hypnotic suggestibility and suggest that HS individuals are comprised of distinct subtypes with dissimilar cognitive profiles.     

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.

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。     

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.
