Association rule learning in neuropsychological data analysis for Alzheimer’s disease

Efficient methods of analysis readily available for clinicians continue to be limited within neuropsychological assessment at the raw data level. Here, a novel approach for generating predictive response patterns and analysing neuropsychological raw data is offered. In order to assess the usefulness of association rule learning as an analysis tool for neuropsychological raw data, Frequent Pattern Growth (FP-Growth) was used to mine patterns from the Consortium to Establish a Registry for Alzheimer’s Disease Neuropsychological Battery (CERAD-NB) database. Complete assessment data for 84 post-mortem confirmed Alzheimer’s disease (AD) cases and 294 age, race, and education matched controls were analysed across baseline and one-year follow-up using FP-Growth, for the purpose of assessing the clinical utility of a finer analysis at the raw data level and the feasibility of predicting response patterns for clinical/control groups. Output from FP-Growth, in terms of the number of frequent itemsets retained across both evaluation timepoints, was discernable between controls, mild, and moderate to severe Alzheimer’s disease cases (p < .001, and η² = .488). Patterns within raw data scores, both in terms of frequent itemsets and predictive association rules, appear to be differentiable across groups within neuropsychological analysis, which indicates that FP-Growth is applicable as a supplementary analysis tool for neuropsychological assessment by means of offering an additional level of data analysis, predictive item response capabilities, and aiding in clinical decision making.     

Mirror reading of words and numbers: Practice and transfer effects

It remains unknown whether mirror reading represents a genuine text processing skill or is based on recognition of visual patterns. The present study attempts to determine whether (1) systematic practice with a particular mirrored typography also improves reading performance for other mirrored typographies, and whether (2) this transfer extends from lexical to numerical material and vice versa. The results show that short-term intensive practice with mirror-reversed words significantly improves reading performance not only for the trained typography but also for other mirrored typographies and mirror-reversed Arabic digits. Practice with mirror-reversed Arabic digits showed a mixed pattern of transfer effects with regard to other digit transformations and there were no transfer effects to lexical material. Hence, for lexical material, at least, improvement after training seems to be based on generalized skill with transfer effects beyond lexical material, rather than on mere improvement of visual recognition of the material used in training.     

“误读”与新义——经学文本诠释刍议

中国的文本诠释学产生于战国时期。从文本诠释的内容、性质和体例看,大致可分为两类。一类是义理诠释学,一般称为"传"。另一类是语言诠释学,一般称为"训诂"或"诂训"。传的特点是"解说经义","并经文所未言者而引申之","多离经"。诂训的特点是"第就经文所言者而诠释之",追求文本原貌、原义。但是,在文本诠释的历史实践中,传往往离不开训诂,训诂也离不开传。"传"的内容在西方诠释学中又称作"误读"。我们借用"误读"的概念只是为了吸收西方文本诠释中的合理成分,并不是同意放弃追求文本原貌、原义的真理性原则。在中国文化史上,"误读"是创建新义理的一种方式,也是为汉语增加新质要素的一种方式。"误读"源于春秋战国间"断章取义"、"以意逆志"、"诗无达诂"的文本阅读诠释理论,是一种理论创新、语言创新的手段。"误读"在易学发展史上,尤其《易经》与《易传》的关系上有着重要的理论价值,有着突出的解释力。     

中外两种推理理论的实验比较研究

通过两个实验对中国学者提出的“推理题与推理者的推理知识双重结构模型”和Evans提出的“双重加工理论”进行了实验比较研究。实验一通过两种评定方法对相应性质命题进行评定后所得实验结果表明Evans等(1983)有关“信念效应”研究中的“结论可信性”变量可以视为与胡竹菁等(1996)实验中的“内容正确性”变量是同一性质的变量; 实验二根据“形式正确性”和“内容正确性”两个自变量设计的推理实验结果与Evans等(1983)的研究结果基本一致; 但增加“内容熟悉性”这一自变量设计的推理实验结果表明“推理题与推理者的推理知识双重结构模型”比Evans提出的“双重加工理论”能更好地解释推理者对性质三段论的推理结果。     

2 B kreativ’ or not to be creative: Textisms and texters’ creativity

IntroductionText messages are particularly popular among young people. Studies have focused on the links between writers’ unconventional spelling and literacy skills. Creativity gives the possibility to cope with the numerous changes people have to face.ObjectiveThe present research aimed to examine the relation between the creative potential of texters (text-message writers) and their use of textisms (a change in a word's orthographic form as compared to traditional writing).MethodTwo corpora were compiled: one of 285 elicited text messages and one of 580 naturalistic text messages produced in daily-life situations by undergraduates (n = 29, 20–23 years of age). Two types of textisms were measured: those consistent with traditional written code and those breaking with traditional written code. Four scores of creative potential were considered: graphic divergent thinking, verbal divergent thinking, graphic integrative thinking and verbal integrative thinking.ResultsThe results showed negative correlations between the level of creativity and the density of textisms. Overall, texters who were creative in divergent thinking produced fewer textisms breaking with traditional written code.ConclusionThe results of our study are discussed with regard to the texters’ flexibility and ability to adapt or appropriately address their interlocutor.     

平面广告中图形与文本加工差异的眼动研究

记录被试在观看不同文本位置的平面广告时的眼动轨迹,探讨了广告中文本和图形加工的差异性、文本在广告中的不同位置(左上、左下、右下、右上)的加工差异、人们对广告图片及文字的评价与其眼动指标是否具有一致性以及与再认成绩的相关程度等。结果表明,(1)瞳孔大小是比较敏感的指标,在观看广告时,文本的位置及评价水平都可以引起瞳孔大小的改变：而不会对注视时间产生影响。(2)人们对文本和图形的加工方式上存在差异,它不仅表现在眼动指标上,同时也表现在再认成绩上。广告中适当的文字有助于广告内容的记忆。     

Creating cluster‐specific purchase profiles from point‐of‐sale scanner data and geodemographic clusters: improving category management at a major US grocery chain

In the retail grocery industry, category management is the process of managing categories of products for greater profitability and customer value. Category management is a data‐driven process and, as a result, can benefit from point‐of‐sale (POS) scanner data. This paper describes the results of a one‐year project that shows how to use POS scanner data and geodemographic clusters to improve the practice of category management at Price Chopper, a large US grocery chain. The paper demonstrates how to merge POS scanner data with geodemographic clusters to create detailed purchase profiles that provide valuable information to category managers. It also discusses the trials and tribulations of using scanner data and provides several findings as implications (eg store‐specific promotions should be more effective than chain‐wide promotions for stores servicing a small number of geodemographic clusters with distinct shopping profiles) that supermarket managers can immediately use to improve existing promotional strategies. The paper's contents should be relevant to academicians and practitioners interested in improving the practice of category management in the UK, USA, Western Europe and Australia.
