Innovation in Technology-Aided Psychotherapy Through Human Factors/Ergonomics: Toward a Collaborative Approach

Technologies are being used increasingly to aid psychotherapy and are becoming an integral part of mental health treatment. Although prior studies compared technology-aided psychotherapy (TAP) to traditional treatments, there are insufficient studies of the impact that specific design parameters and use of the technologies may have on the client and therapist, and treatment outcomes. This requires an understanding of human–technology interaction, which is the focus of the field of Human Factors and Ergonomics (HF/E). The goal of this article is to raise awareness of the importance of the human–technology interaction in TAP, and to foster collaborations between psychotherapists and HF/E professionals. Toward these aims, this article examines the implications of findings in HF/E for the use of technologies (videoconferencing, text-based communication, and virtual environments) in psychotherapy. It is suggested that the manner in which technologies are designed and used may have important effects on the therapeutic alliance and treatment outcomes, and in some cases (side effects of virtual reality) the health and safety of the client. Future research should examine effects of specific design factors on treatment including variables such as the visibility of gestures and degree of eye contact during videoconferencing, response delays during text-messaging, and presence and adverse effects when using virtual environments. Studies that compare TAP to traditional methods should report as much detail as possible about the human–technology interaction. It is essential that psychotherapists and HF/E professionals conduct research collaboratively to develop effective and innovative technologies and, ultimately, design principles for TAP.     

组织分割供给与工作情绪衰竭的关系:工作心理脱离和工作→非工作冲突的中介作用*

采用问卷调查法,对271名企业管理人员进行调查,探讨了组织分割供给与工作情绪衰竭的关系,以及工作心理脱离和工作→非工作冲突在其中的中介作用。结构方程模型分析表明:(1)组织分割供给不仅可以通过工作→非工作冲突的中介作用负向影响工作情绪衰竭;(2)还可以通过依次影响工作心理脱离和工作→非工作冲突进而负向影响工作情绪衰竭。因此,组织分割供给对个体的非工作角色和工作角色均有积极作用。     

Mechanisms for attentional modulation by threatening emotions of fear,anger, and disgust

Appropriately attending to threatening environmental stimuli is evolutionarily adaptive and crucial for survival. This study revealed that nonconscious attentional modulation of disgust has different behavioral and event-related potential (ERP) patterns, as compared to fear and anger. To facilitate its evolutionary purpose of avoidance, disgust first diverts rather than attracts attention. Accordingly, the N1 was smaller in a validly than in an invalidly disgust-cued condition. Furthermore, the frontal P3a for disgust, anger, and fear was found to be larger in the valid than in the invalid condition, which was interpreted as an involuntary switching of attention toward threat-related events to mobilize cognitive resources for action or defense. On the contrary, the parietal P3b only occurred at the conscious level; the enhanced P3b indicated that more cognitive resources were being allocated toward the task-relevant but previously less attended location, to ensure the effective achievement of task goals. In addition, group comparisons between individuals with low and high disgust sensitivity showed that the ERP differences between the disgust and the anger/fear conditions at the unconscious level may be attributed only to individuals with high disgust sensitivity. These findings, together with previous knowledge of the effects of fear and anger on attention, strengthen our confidence in the two-stage scheme of attentional modulation by threats, which consists of an early stage of bottom-up response scaling of sensory processing (reflected by the P1 and N1) and a later stage of top-down integration and regulation of emotion and behavior (reflected by the P3).     

谦卑型和自恋型领导:跨文化组织管理的视角

谦卑型领导和自恋型领导的概念差异体现在在自我认识、对待他人态度、动机、情绪、行为方式等方面。并且,谦卑型领导和自恋型领导在管理员工、团队、组织方面分别存在优势和劣势,谦卑型领导和自恋型领导之间存在相互独立且共存的关系。基于跨文化管理的视角,研究显示谦卑型领导和自恋型领导存在潜在的文化差异,且具有不同的形成基础,并在内隐领导理论上存在差异,最后,二者均是文化适应性的结果。未来研究可关注谦卑型领导和自恋型领导内涵的文化特异性、前因变量、研究方法、文化动态建构和文化认同强度等问题。     

Tunable wave-vector filtering in a two-dimensional electron gas modulated by magnetic barriers and δ-doping

We report a theoretical investigation on the control of wave-vector filtering (WVF) in a two-dimensional electron gas modulated by realistic magnetic barriers and δ-doping, which can be experimentally realised by depositing a ferromagnetic stripe on the surface of a GaAs/Al_xGa_1?xAs heterostructure and using atomic layer doping. Theoretical analysis demonstrates that a sizeable WVF effect still exists even if δ-doping is introduced into the device. Numerical calculation reveals that the WVF efficiency is related closely to the δ-doping. Thus, the WVF effect in a magnetic nanostructure can be conveniently manipulated by properly adjusting the weight and/or the position of the δ-doping, giving rise to a tunable momentum filter for nanoelectronics applications.     

结构化面试中评分量表对评分准确性的影响

采用2(组内变量:量尺大小(25分和9分))×2(组间变量:评分方法(相对和绝对))的混合实验设计探讨评分量表对115名大学生新手评委评分准确性的影响。对于评分准确性,采用Cronbach1955年提出的四个指标,Elevation(EL)、Differential elevation(DE)、Stereotype accuracy(SA)、Differential Accuracy(DA)。结果发现,评分方法只在SA上主效应显著,量尺大小在只在DA上主效应边缘显著,评分方法和量尺大小在DE、SA和DA三个指标上均有交互作用。总体上看,在结构化面试评分中,对于评分准确性,相对评分量表优于绝对评分量表,小量尺量表优于大量尺量表。

本文从情绪认知理论的角度出发, 通过3个研究探究与感激情绪有关的认知评价维度, 进而建立感激情绪的认知评价体系。研究1使用回忆不同类型的情绪性事件法初步探究了感激情绪的认知评估体系; 研究2使用操作认知评估维度法探究了认知评价的变化对感激体验的影响; 研究3使用故事情境法分别从个体特质和情境因素的角度, 探究个体特质与感激情绪之间的关系如何受到个体认知评价的影响, 进而为感激情绪的评价体系提供更多的证据支持。研究1发现感激情绪体验与受关怀感、符合道德规范和他人负责性3个维度之间存在正相关关系。研究2发现3个认知评估维度体验的有无均会导致个体在感激情绪体验上出现显著差异。研究3表明感激特质可以预测个体的认知评价和感激情绪体验; 同时, 受关怀感、道德规范、他人负责3个认知评价维度在感激特质与感激情绪关系间起到中介作用。结论：3个研究结果表明, 受关怀感、道德规范、他人负责性3个认知评价维度与感激密切相关, 并在区分开感激与自豪、亏欠感等情绪中起重要作用。因此, 这3个认识评估维度共同组成了感激情绪认知评价体系。     

发展性计算障碍的最新研究进展

发展性计算障碍是一种影响算术技能获得的特定的学习障碍。截至目前,有关发展性计算障碍的认知与神经机制的理论尚存分歧,有关诊断与鉴别标准也未统一。近年来,对于发展性计算障碍的理论假设有从一般认知因素取向到数学特定因素取向发展的趋势。而随着脑成像技术的不断发展,对于发展性计算障碍神经机制的研究也从针对单个脑区的特异性功能发展到从功能连接网络角度进行研究。并且研究者们开始尝试开发基于数学认知基本理论的干预方法,并采用了利用生物技术手段的新方法。基因-脑-行为的整合研究将有助于全面揭示发展性计算障碍的发生机制,而建立在系统理论基础上经过科学评估的干预手段将可能有效促进障碍者的计算能力。

为探索成人认知功能的发展与认知老化轨迹,基于中华成人智力量表常模样本数据,统计控制教育水平和职业构成以部分消除同辈效应,考察智商和智力指数的年龄趋势。结果晶体智力指数(CI)在25~44岁间增加0.69分后缓慢递减,高低差值3.3分;注意记忆指数(AMI)在25~44岁间共减少3.3分,45岁后各组均数以3分左右的速度递减。流体智力指数(FI)和智商的年龄差异模式与AMI类似,幅度缩减。提示中国成人晶体智力在74岁前比较稳定,没有明显老化,流体智力和注意记忆能力可能在45岁开始明显线性老化。     

The effect of motion at encoding and retrieval for same- and other-race face recognition

In an experimental study, we assessed the role of motion when encoding and recognizing unfamiliar faces, using an old/new recognition memory paradigm. Our findings revealed a clear advantage for learning unfamiliar faces moving non-rigidly, compared with static faces. This advantage for motion was found with both same- and other-race faces. Furthermore, results indicate that it is more important that the face is learnt in motion than recognized from a moving clip. Interestingly, despite a reliable other-race effect being revealed, participants were able to utilize motion information exhibited by other-race faces in a manner akin to the motion advantage found for same-race faces. The implications of these findings are discussed in relation to the nature of the stored face representations, considering whether the facilitative role found here can be explained by factors other than motion per se.
