Four Covariance Structure Models for Canonical Correlation Analysis: A COSAN Modeling Approach

The mathematical connection between canonical correlation analysis (CCA) and covariance structure analysis was first discussed through the Multiple Indicators and Multiple Causes (MIMIC) approach. However, the MIMIC approach has several technical and practical challenges. To address these challenges, a comprehensive COSAN modeling approach is proposed. Specifically, we define four COSAN-CCA models to correspond with four possible combinations of the data to be analyzed and the unique parameters to be estimated. In terms of the data, one can analyze either the unstandardized or standardized variables. In terms of the unique parameters, one can estimate either the weights or loadings. Besides the unique parameters of each COSAN-CCA model, all four COSAN-CCA models also estimate the canonical correlations as their common parameters. Taken together, the four COSAN-CCA models provide the correct point estimates and standard error estimates for all commonly used CCA parameters. Two numeric examples are used to compare the standard error estimates obtained from the MIMIC approach and the COSAN modeling approach. Moreover, the standard error estimates from the COSAN modeling approach are validated by a simulation study and the asymptotic theory. Finally, software implementation and future extensions are discussed.     

The role of severity and intentionality in the intensity of Schadenfreude attribution: A developmental study of Danish children

Understanding envy and schadenfreude requires complex interpersonal social cognitive abilities, such as social comparison and evaluating the Self, but also understanding agency and intentionality. Previous studies of children's development of envy/schadenfreude addressed whether children understand and experience schadenfreude as opposed to compassion/sympathy or whether children's attribution of schadenfreude is a consequence of envy provoked by a disadvantageous social comparison. In this study, we take a step further and investigate the roles that agency and severity of the damage play in mediating children's attribution of schadenfreude. The participants were 144 Danish children aged 3–9 years divided into two age groups. Children were presented with eight stories supported by pictures showing intentional versus accidental and irreparable versus reparable damage to envied objects. The results show that the intensity of envy/schadenfreude, as well as the happy victimizer phenomenon, varies depending on the severity of damage, agency and intentionality. When damage is accidental, schadenfreude is expressed with less intensity compared to when damage is intentional (led by an agent). When damage is irreparable, children attribute less intense feelings of schadenfreude compared to when it is reparable. In addition, only the older children expressed reparable damage carrying more intense schadenfreude and only in the accidental condition. In general, children consider intentional and reparable damage more intense than accidental and irreparable damage, and this is mediated by age. The results are important for understanding the developmental trajectory of children's complex emotions and for educational programmes directed towards supporting this development.     

The longitudinal relationships of interpersonal openness trait,hostility, and hostile attribution bias

While the relationship between personality, hostility, and hostile attribution bias (HAB) has been explored in previous studies, their longitudinal relationship is unclear, and no related study has utilized the indigenous Chinese personality. This research explored the longitudinal relationships of interpersonal openness (IO; an indigenous Chinese personality construct), hostility, and HAB. The 942 valid participants (38.5% male, mean age = 20.83, standard deviation = 1.04) were from six different provinces in China. Measurements were completed on two separate occasions (Times 1 and 2), with a 6-month interval. Results showed that IO has longitudinal effects on hostility, after controlling for the Big Five, and HAB could be longitudinally predicted by IO and hostility as well. Moreover, hostility served as a mediator in the relationship between IO and HAB. These results suggest that IO can affect the development of hostility and HAB, and some indigenous Chinese personality factors may complement Western personality theories.     

Effects of auditory rhythm on movement accuracy in dance performance

The present study addresses the impact of the rhythmic complexity of music on the accuracy of dance performance. This study examined the effects of different levels of auditory syncopation on the execution of a dance sequence by trained dancers and exercisers (i.e., nondancers). It was hypothesized that nondancers would make more errors in synchronizing movements with moderately and highly syncopated rhythms while no performance degradation would manifest among trained dancers. Participants performed a dance sequence synchronized with three different rhythm tracks that were regular, moderately syncopated, and highly syncopated. We found significant performance degradation when comparing conditions of no syncopation vs. high syncopation for both trained dancers (p = .002) and nondancers (p = .001). Dancers and nondancers did not differ in how they managed to execute the task with increasing levels of syncopation (p = .384). The pattern of difference between trained dancers and nondancers was similar across the No Syncop and Highly Syncop conditions. The present findings may have marked implications for practitioners given that the tasks employed were analogous to those frequently observed in real-life dance settings.     

The hand of God or the hand of Maradona? Believing in free will increases perceived intentionality of others’ behavior

The question of whether free will actually exists has been debated in philosophy for centuries. However, how belief in free will shapes the perception of our social environment still remains open. Here we investigate whether belief in free will affects how much intentionality we attribute to other people. Study 1a and 1b demonstrate a weak positive relation between the strength of belief in free will and the perceived intentionality of soccer players committing handball. This pattern even holds for behavior that is objectively not intentional (i.e., when the player touches the ball accidentally). Going one step further, in Study 2 we find a weak correlation between belief in free will and perceiving intentions in very abstract geometrical shapes. These findings suggest that whether individuals believe in free will or not changes the way they interpret others’ behavior, which may have important societal consequences.     

敌意归因偏向对反应性攻击的预测及报复动机的中介作用

敌意归因偏向指将模糊情境中他人的行为意图进行敌意归因的倾向,其被认为是导致攻击的主要认知因素,但还缺乏其与反应性、主动性攻击的纵向关系的考察,而且其影响反应性攻击的动力机制也不清楚。本研究通过两个子研究来分别回应这两个问题。研究1的纵向调查结果显示,敌意归因偏向只纵向预测反应性攻击,而不能跨时间地预测主动性攻击。研究2对另一批大学生的横断面调查发现,报复动机可以中介敌意归因偏向与反应性攻击的关系。研究结果提示,敌意归因偏向很可能主要是在反应性攻击的形成中起到重要作用,而对主动性攻击的影响不大,报复动机则很可能是这种作用背后的动力机制之一。     

听觉预测编码：对声音重复和变化的神经反应

预测编码被认为是脑与复杂环境交互的重要机制之一, 有效感知外界环境并对未来事件做出预测, 对个体生存有着至关重要的意义。人类大脑会基于感觉输入以迭代的方式持续优化表征外部环境的内部模型, 并不断预测接下来的感觉输入。以听觉模态为例, 人类及动物对声音重复和听觉变化的神经反应(如失匹配负波和刺激特异性适应)是大脑预测编码的重要体现, 表现为重复抑制和预测误差。结合人类和动物模型在此理论框架下开展跨物种研究将有助于加深我们对听觉加工, 甚至是大脑工作机制的认识。     

Priors in perception: Top-down modulation,Bayesian perceptual learning rate,and prediction error minimization

I discuss top-down modulation of perception in terms of a variable Bayesian learning rate, revealing a wide range of prior hierarchical expectations that can modulate perception. I then switch to the prediction error minimization framework and seek to conceive cognitive penetration specifically as prediction error minimization deviations from a variable Bayesian learning rate. This approach retains cognitive penetration as a category somewhat distinct from other top-down effects, and carves a reasonable route between penetrability and impenetrability. It prevents rampant, relativistic cognitive penetration of perception and yet is consistent with the continuity of cognition and perception.     

Predictions,precision, and agentive attention

Ransom, Fazelpour, and Mole (this journal - 2017) raise an important puzzle for the ‘prediction error minimization’ account of cognitive processing. That account depicts all cognitive processing as fundamentally in the business of minimizing prediction errors concerning the evolving flow of sensory information. One of the cornerstones of these highly ambitious, would-be unifying accounts is their depiction of attention as nothing other than the process of optimizing the precision (inverse variance) of critical prediction error signals. But that story, Ransom et al. suggest, cannot accommodate voluntary shifts of attention. In this paper, I show why this challenge to the grand unifying project fails. It fails because it locates the origins of voluntary attention in complexes of unanalyzed desire rather than in changing complexes of beliefs.
