The Interdisciplinarity of Collaborations in Cognitive Science

We introduce a new metric for interdisciplinarity, based on co‐author publication history. A published article that has co‐authors with quite different publication histories can be deemed relatively “interdisciplinary,” in that the article reflects a convergence of previous research in distinct sets of publication outlets. In recent work, we have shown that this interdisciplinarity metric can predict citations. Here, we show that the journal Cognitive Science tends to contain collaborations that are relatively high on this interdisciplinarity metric, at about the 80th percentile of all journals across both social and natural sciences. Following on Goldstone and Leydesdorff (2006), we describe how scientometric tools provide a valuable means of assessing the role of cognitive science in broader scientific work, and also as a tool to investigate teamwork and distributed cognition. We describe how data‐driven metrics of this kind may facilitate this exploration without relying upon rapidly changing discipline and topic keywords associated with publications.     

Birth of the cool: a two-centuries decline in emotional expression in Anglophone fiction

The presence of emotional words and content in stories has been shown to enhance a story’s memorability, and its cultural success. Yet, recent cultural trends run in the opposite direction. Using the Google Books corpus, coupled with two metadata-rich corpora of Anglophone fiction books, we show a decrease in emotionality in English-speaking literature starting plausibly in the nineteenth century. We show that this decrease cannot be explained by changes unrelated to emotionality (such as demographic dynamics concerning age or gender balance, changes in vocabulary richness, or changes in the prevalence of literary genres), and that, in our three corpora, the decrease is driven almost entirely by a decline in the proportion of positive emotion-related words, while the frequency of negative emotion-related words shows little if any decline. Consistently with previous studies, we also find a link between ageing and negative emotionality at the individual level.     

The just world hypothesis as an argumentative resource in debates about unemployment benefits

The concept of the “just world” is established as a key explanation for how people make sense of inequality so that those deemed to score high in belief in a just world are more likely to hold prejudicial beliefs and to blame people in poverty for their situations. However, this is an inadequate explanation for such complicated and controversial issues. To better understand talk about the just world and the controversial issue of the distribution of unemployment benefits (an issue of inequality), a discursive psychological approach to the just world is used. Therefore, a discourse analysis focusses on 2 feature length British televised discussions about benefit claimants called “The Big Benefit Row: Live” (Channel 5 3/2/2014) and “Benefits Britain: the Debate” (Channel 4 17/2/2014). The analysis demonstrates that people draw on both just and unjust world arguments simultaneously and also topicalise what counts as just so as to support their positions on unemployment benefits, rather than in the consistent way that just world theory would predict. It is therefore argued that the just world should be recast as a cultural value that facilitates arguments about benefits, rather than an internally held belief.     

心理不安全状态下决策者的风险偏好

心理不安全感是指人们对可能遭受的伤害与威胁的担忧与焦虑。当下, 许多个体都是在心理不安全的状态下进行决策。对于心理不安全状态下的风险偏好规律, 现有研究得到了矛盾的结果。此外, 心理安全感对风险偏好的作用机制尚不明确。本研究聚焦心理安全感对风险偏好的影响, 考察心理安全感的补偿机制在其中的中介作用, 并探讨选项分布情况在其中的调节作用, 以此揭示心理安全感为何及如何作用于风险偏好。研究结果将有助于明确决策者在心理不安全状态下的风险偏好规律, 从而完善现有的风险决策理论。同时, 为公共管理政策制定提供科学依据。     

Graph coloring, minimum-diameter partitioning, and the analysis of confusion matrices

It is well known that minimum-diameter partitioning of symmetric dissimilarity matrices can be framed within the context of coloring the vertices of a graph. Although confusion data are typically represented in the form of asymmetric similarity matrices, they are also amenable to a graph-coloring perspective. In this paper, we propose the integration of the minimum-diameter partitioning method with a neighborhood-based coloring approach for analyzing digraphs corresponding to confusion data. This procedure is capable of producing minimum-diameter partitions with the added desirable property that vertices with the same color have similar in-neighborhoods (i.e., directed edges entering the vertex) and out-neighborhoods (i.e., directed edges exiting the vertex) for the digraph corresponding to the minimum partition diameter.     

Small wonders of the Indian market

Heavy competition in India in almost all product categories, due to diversification by large and medium companies and increased entry of multinationals, has restricted the growth of domestic companies. Previously, large companies enjoyed high profit margins by targeting premium priced products in the upper strata of Indian society. High levels of competition from equally reputed brands have not only decreased the companies' market share but also created price wars, reducing profit margins and limiting market growth. This has motivated companies to consider the lower classes and the rural segments, which they had previously ignored. By targeting these segments with products in small packs at lower price points, companies have experienced great success. At the same time, small packs also pose some challenges for the companies. This paper explains the importance of small packs for market expansion in various product categories within the Indian market, drawing on several examples to support the views of the authors.

关系研究的新取向：社会网络分析

社会网络分析（Social Network Analysis, SNA）是用社会实体之间的关系来描述、解释和预测社会现象的一种研究取向。SNA提供了深入探究社会环境特征及其对个体心理发展影响的一种方法。本文基于SNA的发展历程,依次介绍了中心性分析、小团体分析、位置分析、QAP以及统计模型法。SNA在社会学研究中得到了较多应用,近年来在心理学研究中开始受到重视。
