A weighted procrustes criterion

The Procrustes criterion is a common measure for the distance between two matricesX andY, and can be interpreted as the sum of squares of the Euclidean distances between their respective column vectors. Often a weighted Procrustes criterion, using, for example, a weighted sum of the squared distances between the column vectors, is called for. This paper describes and analyzes the performance of an algorithm for rotating a matrixX such that the column-weighted Procrustes distance toY is minimized. The problem of rotatingX intoY such that an aggregate measure of Tucker's coefficient of congruence is maximized is also discussed.We wish to thank Richard A. Harshman and C. F.

SEARCH FOR BELIEFS TO LIVE BY CONSISTENT WITH SCIENCE

Abstract. Instead of separating religion and science into "mutually incompatible realms," the new macromental paradigm of behavioral science permits integration of the two within a single consistent worldview. A new form of causal determinism combines conventional "bottom-up" with emergent "top-down" causation. Traditional materialist tenets are overturned, along with the science-values dichotomy, clearing the way for a science-based value/belief system. Intrinsic ethicomoral directives emerge in which a revised sense of the sacred would help protect the evolving quality of the biosphere, and the rights and welfare of future generations. Subsequent versions of today's changing worldview raise questions of which interpretation to believe. An analysis of "New Age" thinking is called for, and a brief attempt at such analysis is included.     

Basic and applied research on extinction bursts

Discontinuation of the contingency between a response and its reinforcer sometimes produces a temporary increase in the response before its rate decreases, a phenomenon called the extinction burst. Prior clinical and basic studies on the prevalence of the extinction burst provide highly disparate estimates. Existing theories on the extinction burst fail to account for the dynamic nature of this phenomenon, and the basic behavioral processes that control response bursting remain poorly understood. In this paper, we first review the basic and applied literature on the extinction burst. We then describe a recent refinement of the concatenated matching law called the temporally weighted matching law that appears to resolve the above-mentioned issues regarding the extinction burst. We present illustrative translational data based conceptually on the model. Finally, we discuss specific recommendations derived from the temporally weighted matching law regarding procedures clinicians could implement to potentially mitigate or prevent extinction bursts.     

从毕生发展的角度看个体分类倾向的两次转变——材料的生命性和可操作性的作用

研究从毕生发展的视角考察了个体分类倾向的发展轨迹,并探讨任务材料内容可能对其产生的影响。选取幼儿园、小学、中学、大学和中老年个体各30名作为研究对象,记录他们面对不同的分类材料(有/无生命、高/低可操作性)的分类倾向。结果表明个体的分类倾向经历了两次转变:(1)进入小学后主题分类倾向逐渐降低,并在2、3年级时最低;(2)进入中学之后,个体逐渐恢复对主题分类倾向的偏好,中学和大学的个体面对含有生命体或是可操作性高的材料会比面对非生命体或可操作性低的材料时,更倾向于使用主题分类的策略。这一结果表明,个体对不同材料内容的分类倾向的发展轨迹存在差异,研究结果有助于理解个体概念组织的形成和发展过程。     

情绪与认知关系研究发展概况

情绪与认知的关系长期存在着谁主谁从和谁为首因的争议,近期感情神经科学对两者的关系取得了突破性进展。通过从古希腊哲学思想入手分析和介绍中世纪、近现代各个历史时期学者们的不同观点,从而使我们了解情绪与认知从主-从关系、彼此独立的关系、相互作用的关系到互倚关系的艰难认识历程。     

Teaching identity matching of braille characters to beginning braille readers

We taught three children with visual impairments to make tactile discriminations of the braille alphabet within a matching‐to‐sample format. That is, we presented participants with a braille character as a sample stimulus, and they selected the matching stimulus from a three‐comparison array. In order to minimize participant errors, we initially arranged braille characters into training sets in which there was a maximum difference in the number of dots comprising the target and nontarget comparison stimuli. As participants mastered these discriminations, we increased the similarity between target and nontarget comparisons (i.e., an approximation of stimulus fading). All three participants’ accuracy systematically increased following the introduction of this identity‐matching procedure.     

Multilevel analysis of individual differences in regularities of grapheme–color associations in synesthesia

Grapheme–color synesthesia is a neurological phenomenon where visual perception of letters and numbers stimulates perception of a specific color. Grapheme–color correspondences have been shown to be systematically associated with grapheme properties, including visual shape difference, ordinality, and frequency. However, the contributions of grapheme factors differ across individuals. In this study, we applied multilevel analysis to test whether individual differences in regularities of grapheme–color associations could be explained by individual styles of processing grapheme properties. These processing styles are reflected by the type of synesthetic experience. Specifically, we hypothesized that processing focusing on shape differences would be associated with projector synesthetes, while processing focusing on ordinality or familiarity would be associated with associator synesthetes. The analysis revealed that ordinality and familiarity factors were expressed more strongly among associators than among projectors. This finding suggests that grapheme–color associations are partly determined by the type of synesthetic experience.     

Coordination of Emotions in Mother–Infant Dialogues

Eleven infant–mother dyads in Crete were videod during spontaneous interactions at home, from the second to the sixth month of life. Micro‐analysis was used to investigate‘coordination'and ‘non‐matching’ of facial expressions of emotion. ‘Emotional coordination’ was evaluated with four measures: matching of facial expressions, completion when one responded to the other with ‘pleasure’ or ‘interest’, synchrony by matching frequency of change or rhythm of emotional expressions, and attunement when shifts of emotional intensity of the two partners were in the same direction.‘Emotional non‐matching'was coded when neither the infant nor the mother showed interest in interacting with the other. In emotional coordination or non‐matching between mother and infant, who performed first was also recorded. We obtained evidence of emotional matching, synchrony, and attunement. Importantly, the probability of emotional non‐matching by the infant was higher than the probability of emotional matching and completion, indicating a tendency for thoughtful attention or playful rivalry in the responses of infants, who also initiated emotional matching, completion, and non‐matching more frequently than mothers. The probability of expression of emotional matching, completion, and non‐matching changed with age. Both mothers and infants act to obtain sympathetic complementarity of feelings and co‐operative inter‐synchrony of actions. Copyright © 2016 John Wiley & Sons, Ltd.
