Three studies examined the hypotheses that: (1) codability and not extent of distance determines difficulty; (2) critical features and not whole objects are coded; and (3) implicit perceptual axes provide a frame of reference for coding the display. Results supporting these hypotheses are discussed in terms of a description of spatial…

This article explores a model of lexicalisation based upon the constraints that lexicalisation is an interactive process and that it takes place in two stages. The article examines in depth the time-course of normal lexicalisation, speech error data, and the cognitive neuropsychology of speech production. (16 references) (CK)

Presents the first stage in a research effort developing a detailed computational model of working memory. The central feature of the model is counterintuitive. It is assumed that there is a primacy gradient of activation across successive list items. A second stage of the model is influenced by the combined effects of the primacy gradient and…

Two studies involving 195 undergraduates investigated memory errors occurring when the context standard used in judging target behaviors differs from the category norm standard available when behaviors are recalled. Results support a "natural" tendency to use the current categorical meaning of a judgment to reconstruct the referent of…

Sixty-four adults were tested on simple addition and multiplication problems presented in Arabic digit or English number-word format. Overall, response times and error rates were much higher with the word format, but more important, presentation format interacted with arithmetic operation and problem size. (DR)

Investigates how accurately writers detect violations of the writing rules of Simplified English (SE) and what sorts of mistakes are likely to be made when text is rewritten to conform to SE rules. Concludes that training tools such as the Simplified English Analyser can lessen the writers' difficulties. (SR)

Asserts that distinction between "error" and its social implications is false and that research and teaching based on that distinction is flawed. Considers how errors might be viewed as social in their production and correction, examines two ways in which this is elided in the literature, and explores how a social view of error might inform…

Lists the 50 most common writing errors made by college students of French. Mistakes in spelling, vocabulary, and grammar are included. (CK)

In one approach to French second-language instruction, students use free writing assignments to express themselves in their newly learned second language. The primary objective is to encourage students to use the language in a nonthreatening context; it also offers the teacher insights into student problems and needs. (MSE)

Research and practice in detecting and controlling for cheating on objective tests are reviewed and a small survey of attitudes and practices is reported. Potential of two computer programs to detect error similarities and use of multiple answer-sheet forms to control cheating are discussed. Teacher cheating is also addressed. (Author/MSE)

A discussion of errors made in second-language learning focuses on the control that the speaker himself exerts over mistakes and argues that this would be a useful area for further research. Implications of such analysis for second-language instruction are considered. (MSE)

Findings of four investigations involving five through seven year olds suggest that, even though children can make relatively accurate judgments of their knowledge states, they tend to overestimate their competence when assessing their knowledge in relation to performance on a task. (RH)

Using simulation, the effect that misspecification of elements in the weight matrix has on estimates of basic parameters of the linear logistic test model was studied. Results indicate that, because specifying elements of the weight matrix is a subjective process, it must be done with great care. (SLD)

Describes how to use intonation and dialog context to improve the performance of an automatic speech-recognition system. Experiments utilized the DCIEM Maptask corpus, using a separate bigram language model for each type of move and showing that, with the correct move-specific language model for each utterance in the test set, the recognizer's…

Article dispels the following myths about attention-deficit/hyperactivity disorder (ADHD): it has neurobiological base that can only be treated with medication; it must be treated with contingency management procedures; the children do not perform well under partial reinforcement schedules; and students must receive special-education services.…
