Oceans of stimuli: an individual-based model to assess the role of olfactory cues and local enhancement in seabirds’ foraging behaviour

Animal Cognition - Oceans are extremely dynamic environments, which poses challenges for top-predators such as seabirds to find food resources. Yet, seabirds evolved sensorial abilities (olfactory...     

A mixture model for responses and response times with a higher-order ability structure to detect rapid guessing behaviour

Many educational and psychological assessments focus on multidimensional latent traits that often have a hierarchical structure to provide both overall-level information and fine-grained diagnostic information. A test will usually have either separate time limits for each subtest or an overall time limit for administrative convenience and test fairness. In order to complete the items within the allocated time, examinees frequently adopt different test-taking behaviours during the test, such as solution behaviour and rapid guessing behaviour. In this paper we propose a new mixture model for responses and response times with a hierarchical ability structure, which incorporates auxiliary information from other subtests and the correlation structure of the abilities to detect rapid guessing behaviour. A Markov chain Monte Carlo method is proposed for model estimation. Simulation studies reveal that all model parameters could be recovered well, and the parameter estimates had smaller absolute bias and mean squared error than the mixture unidimensional item response theory (UIRT) model. Moreover, the true positive rate of detecting rapid guessing behaviour is also higher than when using the mixture UIRT model separately for each subscale, whereas the false detection rate is much lower than the mixture UIRT model. The deviance information criterion and the logarithm of the pseudo-marginal likelihood are employed to evaluate the model fit. Finally, a real data analysis is presented to demonstrate the practical value of the proposed model.     

Characterizing observers using external noise and observer models: assessing internal representations with external noise

External noise methods and observer models have been widely used to characterize the intrinsic perceptual limitations of human observers and changes of the perceptual limitations associated with cognitive, developmental, and disease processes by highlighting the variance of internal representations. The authors conducted a comprehensive review of the 5 most prominent observer models through the development of a common formalism. They derived new predictions of the models for a common set of behavioral tests that were compared with the data in the literature and a new experiment. The comparison between the model predictions and the empirical data resulted in very strong constraints on the observer models. The perceptual template model provided the best account of all the empirical data in the visual domain. The choice of the observer model has significant implications for the interpretation of data from other external noise paradigms, as well as studies using external noise to assay changes of perceptual limitations associated with observer states. The empirical and theoretical development suggests possible parallel developments in other sensory modalities and studies of high-level cognitive processes.     

评“自己讲”、“讲自己”的哲学史观——与张立文先生商榷

近年来,走出中国哲学的合法性危机、探索中国哲学史研究的范式创新是学者们关注较多的话题。在讨论中,也出现了一些有建设性的意见。其中,著名学者张立文先生的“自己讲”、“讲自己”的观点尤其引人瞩目。张先生在此方面的系列观点,对于增进中国学者研究中国哲学的自主性来说,有一定的积极意义。然而,张先生关于“自己讲”、“讲自己”、“中国哲学转生规律”以及“和合学”的论述尚存在诸多待改进的方面。全面、客观地评价“自己讲”、“讲自己”的哲学史观,对于提高中国哲学研究的理论水平来说具有重要意义。     

The Structure and Stability of Subjective Well-Being: a Structure Equation Modelling Analysis

The purpose of the study is to test the structure and the stability of Subjective Well-Being (SWB), measured through cognitive and affective self-report measures, in global and specific levels of analysis. A sample of 303 adult students was collected and replicated in a 2 month interval. The best model of SWB shows an intercorrelated four-factor structure—Satisfaction with Life, Negative Affect, Positive Affect and Global Subjective Well-being. Results suggest that Global Happiness and Global Satisfaction are measuring the same aspect of SWB. All measures of SWB, in study, show good construct validity and reliability in a 2 month replication. Positive and Negative Affect are significantly weakly correlated. Positive Affect is the most stable variable of SWB, in a short-term interval. Researchers must be aware of the issues related to the measurement of SWB as the order of the items in a questionnaire and the implications of using global or specific measures, cognitive or affective dimensions of the concept, that represent different aspects of the concept. Further study is needed to analyse the structure of SWB with different measures and the relationship between its components.

知觉和概念信息对3岁儿童归纳推理的影响

采用经典的三角归纳范式(Gelman & Markman,1986)研究了3岁儿童的归纳推理及其影响因素。采用龙长权、路晓英、李红和范籍丹(2008)的研究中相同的实验材料和程序,测试了3岁儿童的归纳,结果表明3岁儿童基于知觉相似和基于概念类别之间的差异不显著(实验一)。增加了与靶刺激在知觉上不相似且不属于同一类别的分心刺激之后,3岁儿童能够忽略分心刺激,表明3岁儿童不是在随机猜测(实验二)。分类实验表明3岁儿童能够根据概念关系对实验材料中的项目进行分类,表明3岁儿童具有关于实验项目的概念知识(实验三)。提高概念比较刺激与靶刺激的知觉相似程度,降低知觉比较刺激和概念比较刺激与靶刺激在知觉相似上的冲突程度之后,3岁儿童基于知觉相似和基于概念类别选择之间的差异仍不显著,表明抑制控制不是导致儿童在实验一中表现出基于知觉相似和基于概念类别之间差异不显著的原因(实验四)。降低概念比较刺激与靶刺激之间的类别等级结构,使概念比较刺激与靶刺激属于相同的基本水平类别时,3岁儿童能够主要基于概念类别进行归纳(实验五)。增加经典三角测试的前提的数量,3岁儿童也能主要基于概念类别进行归纳(实验六)。这些研究表明,3岁儿童在一定条件下能够基于概念类别进行归纳,多个因素能够影响3岁儿童在三角测试中的表现。     

Developing a new measure of independent and interdependent views of the self

Following concepts introduced by Markus and Kitayama [Markus, H. R. & Kitayama, S. (1991). Culture and the self: implication for cognition, emotion, and motivation. Psychological Review, 98, 224–253.], two studies were conducted to develop and test a new scale to measure individualism and collectivism, each with its seven constituent facets. The proposed two-dimensional structure was supported by exploratory factor analyses of Chinese and British samples of general populations. The new Independent and Interdependent Self Scale (IISS) was found to have satisfactory reliability and validity across five independent samples of Chinese and British students and community adults. The strengths and limitations of the present research as well as future directions for research are discussed.     

Indigenous and Cultural Psychology: Understanding People in Context

There is growing recognition that psychological theories and principles developed in the West may not accurately reflect those found in other cultures. The newly published book entitled Indigenous and Cultural Psychology: Understanding People in Context has made an important contribution in expanding the scope of psychology. The contributing authors depicted their ultimate goal of developing a universal psychology. The purpose of this article is to review the book from a transpersonal psychology perspective with the hope of facilitating this process. Basing our thoughts on the theoretical framework of perennial psychology and positive psychology, we will suggest practical steps through which future psychologists may work collaboratively to bring about global moral transformation that is crucial to the survival of our planet.     

不同心理刺激诱发的交感和副交感神经活动的比较

让24名女大学生被试完成划消测验、镜画测验、心算和准备演讲四种应激任务,目的在于探讨在不同心理刺激下交感和副交感神经系统的活动是否存在差异。记录HRV（Heart Rate Variability,心率变异性）的频域成分TP（Total Power,总功率）、HF（High Frequency,高频）、LF（Low Frequency,低频）、LF/HF（低频高频比）、平均R-R间期和血压等指标在基线和不同应激任务期间的变化。通过单因素重复测量方差分析和多重比较发现,准备演讲期间的TP、LF值显著地高于基线和其它三项任务, HF的值显著地高于划消测验和心算;镜画测验、划消测验和心算期间的LF值与基线比较显著下降,TP、LF和HF三项指标在这三项任务之间无显著差异;不同任务期间在LF/HF上无显著主效应。平均R-R间期基线水平与所有任务间的比较及各任务之间有显著差异。收缩压基线水平与划消、镜画任务间的比较有显著差异。结果表明,准备演讲期间的交感神经和副交感神经张力显著地大于其它任务,不同任务表现出的不同的自主神经张力变化说明交感神经与副交感神经活动不是一方活动增强、另一方活动减弱的单纯的活动方式,这一结果为Berntson提出的自主神经活动可能存在九种活动搭配模式的理论提供了实验证据
