Investigating local and global effects of surface colours and contours in amodal completion

ABSTRACT

We studied interpretations of partly occluded shapes. Models that account for amodal completion mostly deal with local and global contour characteristics. In the current study, we were interested in the effects of colour on local and global contour completions. In our stimuli, local contour completions comprised simple linear extensions of the partly occluded contours, whereas global contour completions accounted for global shape regularities. Our stimuli were designed such that the visible surface colour could also be completed in a local or global fashion, being consistent or inconsistent with contour completions. We tested the preferred interpretations of the partly occluded shapes by using a sequential matching task. Participants had to judge whether a test shape could be a previously shown partly occluded shape. We found that interpretations of partly occluded shapes depend on both colour and contour characteristics. Additional time bin analyses revealed that for fast responses colour and contour completions already depend on the visible context of the partly occluded shapes, while for slow responses the congruency between colour and contour completions play a role as well.     

Reflections on relational readings of organizational learning

In this concluding article we further reflect on relational readings of organizational learning and how they can contribute to organization studies and organizing practices. As has been seen, the root metaphor of “organizational learning” takes a variety of forms. These include “product-oriented” pictures such as learning curves, strategy, and business processes, and the generative metaphor of organizational learning as conversations-for-new-possibilities. This special issue highlights the contribution of learning-as-conversations, especially in those organizational instances where the organizing is “in-the-making” and where the creation of a transitional space can be a new meeting ground for participants. In an increasingly globalized world we are more and more in need of the ability to construct such transitional and possibility-enabling practices. It can be a task of work and organizational psychology to contribute ideas and practices for this endeavour.     

广告语言与产品卷入度对广告卷入度的影响研究

从产品角度对地方语广告进行研究。本研究将语言熟练度和地域文化认同这两个因素作为控制变量,选取产品卷入度作为调节变量,分别在语音和文本广告两种不同的广告媒介中,研究广告语言（普通话VS粤语）对广告卷入度（认知卷入度VS情感卷入度）的影响机制。结果表明：对于高卷入度产品广告,普通话比粤语产生的广告认知卷入度和情感卷入度都更高;对于低卷入度产品广告,无论广告使用普通话抑或粤语,消费者对广告的认知卷入度都没有显著差异,但粤语比普通话能带来更高的广告情感卷入度。     

What makes a saint? A Lincoln case study in the communion of the local and the universal Church

Within the curtilage of Lincoln Cathedral lie buried the remains of three very different people to whom sainthood has been attributed: Saint Hugh, Bishop of Lincoln (d.1200); 'Little Saint Hugh' (d.1255), a child maliciously alleged to have been murdered by the local Jewish community; and Edward King (d.1910), Anglican Bishop of Lincoln. Hugh is a saint of the Catholic Church, commemorated by Catholics and Anglicans; 'Little Saint Hugh' was for a short while acclaimed by local people as a saint but never officially recognised as one; Edward King is commemorated by Anglicans but not formally recognised as a saint. The marked difference of approach to the attribution of sainthood between local Christians and Catholic Church authorities, as well as between Catholics and Anglicans, is illustrated by this case study, which raises important ecumenical questions: 'What makes a saint?’, ‘How are non-Catholics to regard the Roman Catholic procedure for beatification and canonisation?’, ‘To what extent can there be fully ecumenical calendars of local saints?’, ‘Does beatification offer a way forward by which Catholics may recognise the holiness of non-Catholic Christians?’     

Multiple Local Solutions and Geomin Rotation

In exploratory factor analysis, factor rotation is conducted to improve model interpretability. A promising and increasingly popular factor rotation method is geomin rotation. Geomin rotation, however, frequently encounters multiple local solutions. We report a simulation study that explores the frequency of local solutions in geomin rotation and the implications of such phenomena. The findings include: (1) multiple local solutions exist for geomin rotation in a variety of situations; (2) ? = .01 provides satisfactory rotated factor loadings in most situations; (3) 100 random starts appear sufficient to examine the multiple solution phenomenon; and (4) a population global solution may correspond to a sample local solution rather than the sample global solution.     

Positive Affect and Flexibility: Overcoming the Precedence of Global over Local Processing of Visual Information

Previous findings on the relationship between positive mood and global processing are often based on visual matching tasks that involve a choice between global and local strategies. Preferences for global processing in positive mood, however, do not imply a reduced ability to process locally. The present experiment tested the assumption that positive affect increases flexibility in cognitive processing as indicated by the ability to overcome global precedence, and to respond rapidly to non-dominant (local) features when the task necessitates it. Consistent with expectations, participants responded significantly faster to local targets after positive compared to neutral and negative prime words. The typical precedence of global over local processing observed after neutral and negative prime words was reversed after positive prime words. Findings support the assumption that positive affect increases cognitive flexibility. Furthermore, findings suggest that mood-related preferences in global versus local processing cannot be generalized to processing ability.     

On The Universal and Local Aspects of Confucianism

To counter the tendency of making Confucianism “localized” and thereby turning Confucianism research into research of local social history, the author criticizes this tendency and thinks it is unilateral to emphasize or stress the importance of a small unit’s locality, but ignore the oneness of the distribution of Confucianism and the universality of Confucian thought. The thesis emphasizes that the main schools of Confucianism in the Song and Ming Dynasties are all not local ones and cannot be reduced to reflections of some local need and social structure. The author points out that we need to self-examine the following phenomena: aggrandizing the function of local social structure to culture and thought, coming down academic schools to reflections of local social benefits, opposing this kind of research to the research of thought itself, thus rejecting philosophical research and analysis of thought itself.     

Is Detecting a Target in a Compound Geometric Shape Influenced by Stimulus Density? A Developmental Study

We studied the pattern of performance in elementary school children and adults detecting a target in compound geometric shapes. The target was randomly presented at the global, local, or neither level of compound shapes with different elemental density. A significant difference between the pattern of performance in children and adults emerged when the geometric shape was constructed with fewer constituent parts. That is, children showed difficulties in recognizing the global level while adults could efficiently process it. We suggest that global processing continues to develop as children grow older. Also, integration ability could benefit from increasing familiarity with the geometric concepts.     

2007《中国成人血脂异常防治指南》解读

《中国成人血脂异常防治指南》（以下简称《指南》）在吸收国内外循证医学证据和经验的基础上,结合我国人群的特点来制定的,尤其是在血脂异常分层切点的确定上,参照我国的流行病学资料,更符合国人的情况。在危险分层上本《指南》将高血压单列,等同于任何其他3项危险因素的集合,对极高危人群的确定更明确,目标值也符合临床实际,更加强调了血脂异常的非药物治疗,以及药物治疗中他汀类药物的地位,并且要关注调脂治疗中的监测。     

A Speeded Item Response Model with Gradual Process Change

An item response theory model for dealing with test speededness is proposed. The model consists of two random processes, a problem solving process and a random guessing process, with the random guessing gradually taking over from the problem solving process. The involved change point and change rate are considered random parameters in order to model examinee differences in both respects. The proposed model is evaluated on simulated data and in a case study.
