Numerical approximation of the observed information matrix with Oakes' identity

An efficient and accurate numerical approximation methodology useful for obtaining the observed information matrix and subsequent asymptotic covariance matrix when fitting models with the EM algorithm is presented. The numerical approximation approach is compared to existing algorithms intended for the same purpose, and the computational benefits and accuracy of this new approach are highlighted. Instructive and real-world examples are included to demonstrate the methodology concretely, properties of the estimator are discussed in detail, and a Monte Carlo simulation study is included to investigate the behaviour of a multi-parameter item response theory model using three competing finite-difference algorithms.     

The role of task preference in the effectiveness of response interruption and redirection

Response interruption and redirection (RIRD) is a common treatment for automatically reinforced vocal stereotypy; it involves the contingent presentation of task instructions. Tasks that are included in RIRD are typically selected based on caregiver report, which may affect the efficacy of RIRD. The purpose of the current study was to evaluate the role of task preference in the efficacy of RIRD for four participants who engaged in vocal stereotypy. We conducted task-preference assessments and selected tasks of varying preferences to include in RIRD. For three out of four participants, the results showed that RIRD with higher preference tasks was not effective at reducing vocal stereotypy, whereas RIRD with lower preference tasks was effective for all participants.     

The entertainment value of conspiracy theories

Many citizens around the globe believe conspiracy theories. Why are conspiracy theories so appealing? Here, we propose that conspiracy theories elicit intense emotions independent of emotional valence. People therefore find conspiracy theories entertaining – that is, narratives that people perceive as interesting, exciting, and attention-grabbing – and such entertainment appraisals are positively associated with belief in them. Five studies supported these ideas. Participants were exposed to either a conspiratorial or a non-conspiratorial text about the Notre Dame fire (Study 1) or the death of Jeffrey Epstein (preregistered Study 2). The conspiratorial text elicited stronger entertainment appraisals and intense emotions (independent of emotional valence) than the non-conspiratorial text; moreover, entertainment appraisals mediated the effects of the manipulation on conspiracy beliefs. Study 3 indicated that participants endorsed stronger conspiracy beliefs when an election event was described in an entertaining rather than a boring manner. Subsequent findings revealed that both organisational (Study 4) and societal conspiracy beliefs (Study 5) are positively associated with sensation seeking – a trait characterised by a preference for exciting and intense experiences. We conclude that one reason why people believe conspiracy theories is because they find them entertaining.     

Attenuated Access to Emotions in Obsessive-Compulsive Disorder

The Seeking Proxies for Internal States (SPIS) model of obsessive-compulsive disorder (OCD) posits that OCD is associated with attenuated access to internal states. Here we explored the implications of this model in the realm of emotions. Participants with OCD, anxiety disorders, and nonclinical control participants completed the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), assessing two domains of emotional intelligence: Experiential emotional intelligence (EI), reflecting the ability to perceive and feel emotions accurately, and Strategic EI, reflecting the ability to understand and manage emotions correctly. As only Experiential EI requires accurate perception of one’s emotions for adequate performance, we predicted an interaction between group and EI area. Specifically, we predicted that compared to both anxiety disorders and healthy control participants, OCD participants would show a larger deficit in Experiential area of the MSCEIT relative to the Strategic area. Results were fully in line with this prediction. Moreover, supporting the specificity of the hypothesized deficit to OCD, participants with anxiety disorders did not differ from nonclinical control participants in their performance, and findings were not attributable to anxiety or depression levels. These results replicate and extend previous findings obtained with analogue samples and suggest that OCD is associated with attenuated access to emotional states, which may be partially compensated for by reliance on semantic knowledge of emotion.     

Emotional Schemas

Beck's cognitive model has stressed the influence of cognitive processing in eliciting and maintaining emotional disorders. The concept of schema is extended in Emotional Schema Therapy to account for beliefs, assumptions, and strategies that comprise problematic theories of emotion that result in unhelpful strategies of emotion regulation and acceptance of emotion. In the present paper the central concepts of Emotional Schema Therapy are elucidated and research supporting the model is reviewed.     

情绪面孔的意识神经相关物及其无意识自动加工：来自事件相关电位的证据

意识的神经相关物尚有争议, 且个体能否无意识自动检测视觉环境变化尚不清楚。本研究采用非注意视盲范式操控视觉意识, 并引入具有社会信息的情绪面孔, 探讨意识的神经相关物以及视觉意识与自动检测变化机制的关系。在A阶段, 部分被试对任务无关的情绪面孔处于无意识水平; 在B阶段, 所有被试对任务无关的情绪面孔处于意识水平; 在C阶段, 所有被试对任务相关的情绪面孔处于意识水平。结果显示, 任务无关的情绪面孔的意识过程诱发视觉意识负波(visual awareness negativity, VAN)、晚期正成分(late positivity, LP)和晚期枕区正成分(late occipital positivity, LOP)。此外, 无意识的情绪面孔能诱发视觉失匹配负波(visual mismatch negativity, vMMN), 且其幅值不受意识影响, 但是受任务相关性调制。这些结果提示对情绪面孔的视觉意识在不同的时间进程上有不同的ERP指标——VAN反映早期知觉经验, 而LP和LOP反映晚期意识过程, 而且面孔情绪信息的自动加工独立于视觉意识, 但是受视觉注意调制。     

引入眼动注视点的联合-交叉负载多模态认知诊断建模

多模态数据为实现对认知结构的精准诊断及其他认知特征(如, 认知风格)的全面反馈提供了可能性。为实现对题目作答精度、作答时间(RT)和视觉注视点数(FC)的联合分析, 本文基于联合-交叉负载建模法提出3个多模态认知诊断模型。实证研究及模拟研究结果表明: (1)联合分析比分离分析更适用于多模态数据; (2)新模型可直接利用RT和FC中信息提高潜在能力或潜在属性的估计准确性; (3)新模型的参数估计返真性较好; (4)忽略交叉负载所导致的负面结果比冗余考虑交叉负载所导致的更严重。     

父母教养投入对青少年情绪和行为适应的影响差异:亲子依恋的中介作用

为比较同一家庭父亲与母亲教养投入对青少年情绪和行为适应的影响及作用机制差异,采用问卷对1155名中小学生进行调查。结果表明:(1)父亲教养投入显著预测青少年情绪适应,母亲教养投入显著预测青少年行为适应;(2)父亲教养投入仅通过父子依恋的完全中介作用影响青少年的情绪和行为适应; 母亲教养投入既通过母子依恋的部分中介作用影响青少年的消极行为适应,也通过父子依恋的部分中介作用影响青少年的情绪和行为适应。结论表明:父亲与母亲教养投入对青少年情绪和行为适应的直接影响存在适应领域的特异性,其作用机制也存在差异。本研究精准地区分出父亲与母亲教养投入影响青少年适应性的特定范围及不同的作用机制,这对于同一家庭内的父亲与母亲教养投入的精准干预提供了新的视角。     

集体仪式促进群体情绪感染的机制

近年来, 诸多学者将研究视角投向群体情绪感染, 即群体内部成员间的情绪感染交互过程。群体情绪感染不仅包括个体间的直接情绪感染, 而且受到群体认同、共同行为以及集体规则等多方面因素的影响。基于集体仪式的过程框架, 分析集体仪式的三要素即同步动作、共享注意和共享意义与群体情绪感染的关系, 能更清楚阐述群体情绪感染的发生与增强过程：集体仪式通过自我定型和自我锚定增强群体认同, 在认同基础上的身份融合促进个体关注群体身份, 导致个体的自我表征发生转化, 社会自我的突出使其更容易接受群体的观点和情感表达, 最终增强了群体情绪感染。未来研究应进一步考察群体情绪感染的影响因素并丰富其测量方法。
