不稳定控制感剥夺损害工作记忆刷新功能

控制感剥夺会阻碍工作记忆中的转换功能,但对工作记忆中刷新功能的影响机制尚不清楚。据此,本文通过两个实验来探究控制感剥夺对工作记忆刷新功能的影响。结果发现,相较于基线水平,无论是通过行为无助任务（实验1）还是通过信息无助任务（实验2）操纵的稳定控制感剥夺均未阻碍随后的刷新任务;但在不稳定控制感剥夺的条件下（实验2）,刷新任务的成绩显著降低。这表明,控制感剥夺对工作记忆刷新功能的影响依赖于对其操纵的稳定性。     

现实场景典型空间位置关系客体的解码效应

通过探讨典型空间关系客体对中单个客体的视觉工作记忆,考察空间位置关系的解码特征和主动客体记忆优势。结果发现：（1）当客体以符合空间位置关系方式呈现时,记忆更准确;（2）符合空间位置关系条件下单个客体提取反应时更长,上方客体反应时更短,记忆更准确;（3）兼具空间位置关系与动作关系客体对中的主动客体记忆正确率更高。结果表明,现实场景客体空间分组中单个客体提取时存在解码现象和顺序效应,对现实中的上方与主动客体存在加工偏好。     

任务数量与工作记忆容量对交错学习的影响

研究以分子结构式为材料,让被试在单任务或双任务条件下以集中呈现和交错呈现的方式进行学习,并通过操作广度、旋转广度和对称广度任务测量工作记忆容量（working memory capacity, WMC）,探究在基于规则类别学习中交错呈现优势的稳定性。结果显示,交错呈现优势仅体现在文科生中;而对于理科生,集中呈现效果较佳。另外,任务数量和WMC均不影响交错呈现优势,表明交错呈现优势稳定存在于单任务和双任务条件中,且不同WMC的个体均能从交错学习获益。     

Individual Differences in Susceptibility to Misinformation Effects and Hindsight Bias

The present study examined individual differences in susceptibility to two similar forms of memory distortion: the misinformation effect and hindsight bias. The misinformation effect occurs when individuals witness an event, are provided with misinformation, and recall the original event as containing elements of the misinformation. Hindsight bias occurs when individuals make judgments, are provided with feedback, and recall their original judgments as being more similar to the feedback than they actually were. Seventy-five participants completed a misinformation task, a hindsight bias task, and several individual difference measures related to memory distortions. Working memory capacity was negatively correlated with the misinformation effect and hindsight bias, and the misinformation effect and hindsight bias were negatively correlated with one another. Although the misinformation effect and hindsight bias are measured with similar designs, and both are predicted by working memory capacity, the negative correlation between them suggests these phenomena result from somewhat different processes.     

Theory and teen dating violence victimization: Considering adolescent development

Teen dating violence is an important public health problem, with implications for the future health and well-being of adolescents. However, most work on teen dating violence has developed separately from literature on normative adolescent romantic relationships and development; understanding teen dating violence within the framework of adolescent psychosocial development may provide new areas for research. Thus, the present paper summarizes five theories of adolescent development that are relevant to the study of teen dating violence victimization, as well as empirical literature that demonstrates support for key theoretical tenets in research examining adolescent romantic relationships. We also present questions for future dating violence study that arise from these key theoretical tenets and past empirical research. Researchers interested in dating violence victimization can use the presented theories to guide new directions in research inquiry, so that findings are situated within the broader field of adolescent development.     

Client as expert: A Delphi poll of clients’ subjective experience of therapeutic alliance formation variables

This study extends prior research that identified client-derived variables believed to contribute to therapeutic alliance development. Forty-two clients participated in a three-round-modified Delphi poll in which the subjective importance of 74 client-derived, common alliance formation variables was rated using a six-point scale. Participants consensually identified 23 variables as highly important, five as moderately important and three as low in importance to the formation of a strong alliance. Variables related to validation and asking about parts of the client’s life other than the presenting concern were considered as most important by at least one-third of the sample. Limitations of the study are presented and implications for theory, measurement, practice and future research are briefly discussed.     

视觉工作记忆负载对偏差干扰调控的ERP研究

采用事件相关电位技术（ERPs）,对听视跨通道不同工作记忆负载下偏差干扰效应的加工机制进行研究。当视觉线索50%时,比较有无工作记忆负载条件下偏差干扰效应,分析偏差刺激与标准刺激诱发的差异波,结果发现：（1）存在工作记忆负载和偏差干扰效应;（2）有无工作记忆负载下差异波均出现明显的N1/MMN成分、NP3和RON成分;（3）差异波中N1/MMN成分的平均波幅和潜伏期均没有差异,NP3成分的平均波幅下降;RON成分在平均波幅上没有差异,潜伏期上有工作记忆负载下显著小于无工作记忆负载。研究表明视觉工作记忆负载对偏差干扰调控过程的神经机制并不会因为无关信息与相关信息间冲突竞争增强而改变。     

Visual attribute modulates the time course of iconic memory decay

Studies on iconic memory demonstrate that rich information from a visual scene quickly becomes unavailable with the passage of time. The decay rate of iconic memory refers to the dynamics of memory availability. The present study investigated the iconic memory decay of different stimulus attributes that comprised an object. Specifically, in Experiment 1, participants were presented with eight coloured numbers (e.g., red 4) and required to remember only one attribute, either colour or number, over different blocks of trials. The participants then reported the cued attribute in which the cue Stimulus Onset Asynchrony (SOA) from the memory array onset was varied (0, 100, 200, 300, 500, and 1000?ms). We found that numerical information became unavailable more quickly than colour information, despite the fact that the memory accuracies at 0 and 1000?ms SOAs were comparable between the two attributes. In Experiment 2, we replicated the finding that a numerical representation was lost more quickly than a colour representation when visual masks followed the target stimulus. These results suggest that the various visual attributes comprising an object are lost over time at different rates in iconic memory. We discuss this finding in relation to how perceptual representation is transferred to the capacity-limited visual working memory.     

The supervisory alliance: Comparison of measures and implications for a supervision toolkit

Background Clinical supervision lies at the core of the professional development of clinicians providing services within a range of service settings. The supervisory alliance is regarded as the most important construct in effective supervision which underlies the importance of metrics to assess this construct. Aims materials and Method A cross‐sectional self‐report questionnaire design was used to examine clinical supervision constructs. The study used two scales measuring the supervisory alliance (SRQ and SWAI‐T), a scale measuring supervision satisfaction (SSQ) and a scale measuring disclosure (TDS). The questionnaires were administered to 127 clinical psychology trainees who were undertaking a practicum placement. Results Both scales measuring the alliance were positively correlated with satisfaction with supervision and disclosure, with similar sizes of correlation for each alliance scale. There was also a large, positive correlation between the two scales of measuring the alliance. Discussion Both scales were designed for use in supervision and are related to supervision outcome measures in the expected directions. Conclusion The SRQ has some distinct advantages over the SWAI‐T that lend the SRQ to be potentially more useful in clinical and research settings.
