A probablistic approach to classification and diagnosis of erroneous rules of operations that result from misconceptions ("bugs") in a procedural domain of arithmetic is introcuced. Variability of response errors is explicitly treated through item response theory. As a concrete example, a signed-number subtraction dataset is analyzed.…

In a modified replication study, a general question intended to capture spontaneous detection of inconsistent information found neither good nor poor comprehenders successful. In response to a specific question, however, good comprehenders evinced far superior error detection than poor comprehenders. Reasons are speculated upon. (Author/MT)

The need for developing a technology of teaching that equals current sophistication of microcomputer technology is addressed. The importance of principles of learning and behavior analysis is emphasized. Potential roles of stimulus control and precise error analysis in educational program development and in prescription of specific learning…

Findings suggest that semantic knowledge for concrete objects is represented and organized in similar ways in autistic, retarded, and normal children. Previous findings on cognitive deficits in autistic children are more likely related to their inability to use cognitive representations in an appropriate and flexible manner. (Author/RH)

First examines German modal verbs with respect to multiple meanings and synonymy, finding that "implications," especially presuppositions, account for important differences in their uses. The same approach is used on French modals. Common features and differences are studied, and typical errors are predicted and classified. (Text is in…

Special issue devoted to neurolinguistics and neuropsychology. (VM)

The author argues that a knowledge of mathematical structure is only helpful to the high ability student. (MM)

The present experiment was designed to determine whether there are any important differences in the tendency to repeat errors and correct responses as a function of their having been followed by reward or by information. (Author)

Describes a diagnostic and remedial spelling approach used with high school students. (HOD)

Two studies are reported that examine intraindividual variability in performance on measures of fluid intelligence, varying either practice or testing time conditions. Substantial improvement in level of correct performance is obtained for both conditions; error patterns, however, differ for the two. (Author/GK)

A quantitative description of the segmental errors occurring in the speech of deaf children is developed. Journal availability: Elsevier North Holland, Inc., 52 Vanderbilt Avenue, New York, NY 10017. (Author)

The study compared the productions of 35 articulation impaired children (ages 3 to 10) obtained by picture elicited single word and connected speech sampling methods. Productions were compared on the basis of both the number and type of errors made under the two testing conditions. (Author/PHR)
