A test of the predicted interaction between within-category discontinuity and verbal rule complexity on information-integration and rule-based category learning was conducted. Within-category discontinuity adversely affected information-integration category learning but not rule-based category learning. Model-based analyses suggested that some…

In this dissertation, I develop a definition and regional measure of entrepreneurship that will aid entrepreneurship research and economic development policy. My new indicators represent an improvement over current measures of entrepreneurship. The chief contribution of these new indicators is that they incorporate innovation, which others ignore.…

This article considers the problematic nature of primary headship. It reviews evidence of some of the most significant problems encountered by new and experienced heads derived from two sources: the UK dimension of a European questionnaire survey undertaken in the mid 1990s and more recent reports gained from interviews with serving school…

The aim of this article is the explication of the identity of Comparative Education and a critical reflection thereon, by means of a journal analysis of articles published in the "Comparative Education Review" during the first 50 years of its existence. The 1157 articles were analyzed under the following rubrics: levels of analysis of articles;…

The purpose of the present study was to investigate the presence of teacher biases with regard to identification of students with learning disabilities (LD). Factors related to teachers' gender, age, and experience, along with children's gender, were investigated. Results suggested that teacher gender is associated with biases with regard to…

"Diagnostic classification models" (DCM) are frequently promoted by psychometricians as important modelling alternatives for analyzing response data in situations where multivariate classifications of respondents are made on the basis of multiple postulated latent skills. In this review paper, a definitional boundary of the space of DCM…

This article aims to develop a paradigm of lifelong learning situations. The starting point is the EU-Commission policy document where three kinds of learning situations are identified: formal, non-formal and informal. The article tries to deepen this categorisation by searching for the underlying ontological and epistemological dimensions. The…

We examined the phenotypic expression of attention-deficit/hyperactivity disorder (ADHD) across cultures by assessing the factor/latent class structure of its core symptoms. We conducted a systematic review of the literature published from January 1987 to November 2008 using Medline and PsycINFO. We systematically reviewed 2,511 article abstracts,…

Adaptation to distorted faces is commonly interpreted as a shift in the face-space norm for the adapted attribute. This article shows that the size of the aftereffect varies as a function of the distortion level of the adapter. The pattern differed for different facial attributes, increasing with distortion level for symmetric deviations of eye…

The concept of tri-citation is introduced, as a logical extension of co-citation, and a geometrical model (the circle) is devised to account for these and all other forms of multiple citation. (Author)

Infants exposed to a set of artificially-created face stimuli having distinct mean and modal prototypes showed a pattern of behavior predicted by category abstraction models. Infants appeared to abstract, at the time of learning, a feature-count summary of the category displayed. (Author/RH)

Authors respond to issues raised by commentators concerning their Goals and Process (GAP) matrix. Discuss themes apparent in several commentaries, including nomenclature, the need for a new model, complexity of the model, the omission of task/work groups, and revision of the Association for Specialists in Group Work's model. (Author/MKA)

Maintained that preschoolers' class inclusion task judgments and justification may be modeled as mixtures of different probability distributions, with different response strategies equivalent to different distributions. Found that justifications lagged behind judgments in development. Concluded that, if a single response variable is to be…
