Purpose: The purpose of this paper is to evaluate participants' contributions to the development of discussion and knowledge creation as organizational knowledge management, and thereby help them better develop the discussion. Design/methodology/approach: To evaluate participants' contributions more accurately, a method which analyzes discussion…

We report a new study testing our proposal that word learning may be best explained as an approximate form of Bayesian inference (Xu & Tenenbaum, in press). Children are capable of learning word meanings across a wide range of communicative contexts. In different contexts, learners may encounter different sampling processes generating the examples…

In two experiments, we investigated the morphosyntactic decomposition and semantic composition of acoustically presented German compound words. A left-anterior negativity (LAN) was found in the ERP for gender incongruent, initial compound constituents although these constituents are syntactically irrelevant in German. This LAN provides online…

Positive and negative quantifiers induce two very different perspectives in comprehenders--perspectives that have strong applications to rhetoric and communication. These are briefly reviewed. A potential mechanism, based on earlier work, is introduced, resting on the idea that negatively quantified sentences (like Not all of the boys went to the…

Recent event-related potential studies report a P600 effect to incongruous verbs preceded by semantically associated inanimate noun-phrase (NP) arguments, e.g., "eat" in "At breakfast the eggs would eat...". This P600 effect may reflect the processing cost incurred when semantic-thematic relationships between critical verbs and their preceding NP…

Commenting source code has long been a common practice in software development. This thesis, consisting of three pieces of work, made novel use of the code comments written in natural language to improve software reliability. Our solution combines Natural Language Processing (NLP), Machine Learning, Statistics, and Program Analysis techniques to…

Developmental dyslexia is a highly prevalent and specific disorder of reading acquisition characterised by impaired reading fluency and comprehension. We have previously identified fMRI- and ERP-based neural markers of impaired sentence reading in dyslexia that indicated both deviant basic word processing and deviant semantic incongruency…

Two struggling fourth-grade readers with learning disabilities who have severe deficits in word recognition, comprehension, and reading fluency improve their reading skills using a method that combines intensive word study with the timed repeated reading of poetry. The direct instruction included semantics, morphology, orthography, and…

Classifier languages are spoken by a large portion of the world's population, but psychologists have only recently begun to investigate the psychological reality of classifier categories and their potential for influencing non-linguistic thought. The current work evaluates both the mental representation of classifiers and potential cognitive…

This article describes research undertaken in order to design a methodology for the reticular representation of knowledge of a specific discourse community. To achieve this goal, a representative corpus of the scientific production of the members of this discourse community (Universidad Politecnica de Valencia, UPV) was created. This article…

This study examined differences in performance between 20 shy and 20 matched nonshy children on a narrative task and in the way parents scaffolded their narrative performance when reading the wordless book "Frog, Where Are You", by Mercer Mayer. Consistent with previous research, results demonstrated that shy children spoke less than their nonshy…

Focusing primarily on functional magnetic resonance imaging (fMRI), this article reviews evidence regarding the roles of subregions of the medial temporal lobes, prefrontal cortex, posterior representational areas, and parietal cortex in source memory. In addition to evidence from standard episodic memory tasks assessing accuracy for neutral…

The U.S. Department of Education's National Center for Education Statistics (NCES) has measured various types of high school graduation, completion, and dropout rates for decades. In 2006, NCES was directed by senior managers in the Education Department to reduce use of its standard graduation and completion rate measures and instead promote the…

This paper provides a description of the interactions between a nursery-aged prelingually deaf child and his specialist teacher recorded at four consecutive time points during the first year at school. The child comes from a hearing, Somali-speaking family where English is an additional language (EAL). Using Conversation Analysis procedures,…

This study contributes to research investigating the effects of individual differences and online instructional design on learning. Learning performance was compared across three hypertext formats incorporating different navigational aids. The hierarchical map represented the physical structure of the hypertext in one condition, while the network…
