Discusses recent advances in cognitive theory and the design of computer-based instruction and suggests implications for the design of authoring tools and tutoring system shells. Highlights include the design of courseware; advanced organizers; knowledge representation; design evaluation; models of knowledge; models of errors; and models of…

Investigates the written syntax of 81 college-able individuals demonstrating a specific learning disability. Supports a control impairment hypothesis, predicting that sentence production errors will be of the same kind as found in the language of writers demonstrating no handicapping conditions. Investigates the correlation of specific cognitive…

Examines whether dual-route models of spelling account for the misspellings of Spanish children of different educational levels. Finds that second graders relied heavily on phonological mediation, whereas eighth graders seemed to use a lexical strategy, and fourth-grade children showed an intermediate pattern. Finds support for dual-route spelling…

Investigates whether intermediate Turkish-speaking and English-speaking learners of Spanish know which unaccusative verbs alternate in transitivity and which ones do not, and whether they find causative errors natural with intransitive verbs. Results confirm similar findings to those reported in English interlanguage and first-language acquisition…

Errant mathematical views are widely found among teachers, their students, and authors of applied mathematics texts. Suggests classroom experimentation, both to confirm the occurrence of these errors, and to apply the appropriate corrective teaching. (Author/ASK)

This study investigated whether cognateness affected verbal-confrontation naming performance in balanced French/English bilingual (N-15 aphasic and 15 nonaphasic) subjects. Results of a picture-naming test showed that cognate pictures were more often correctly named in both languages than were noncognates. Some error types and self-correction…

Examined aspects of dyslexia as they became apparent during the construction of geometrical figures by one student as described by another, one of whom had dyslexic symptoms. Found that both dyslexic and non-dyslexic children encountered many communication problems, but that directional confusion of dyslexic students was one of the major…

Examined preschool children's recall of deictic verbs of motion presented within stories either consistently or inconsistently with the protagonist's viewpoint. Found that 3- and 4-year-olds accurately recalled verbs of motion (come, go, bring, take) that were consistent with the protagonist's viewpoint but made substitution errors of…

Discusses the simplification of forms ending in obstruents by native speakers of Mandarin, in particular two effects that are not obviously motivated by either the native- or the target-language grammars: a tendency to devoice final voiced obstruents and a tendency to maximize the number of bisyllabic forms in the output. (Author/JL)

Longitudinal study examined 6-year-olds' performance in tasks involving a protagonist with partial information about an object or a person. Found that children who demonstrated some understanding of the consequences of limited information access often made other errors. Despite intervening additions of contextual support and clarifications, the…

Explores the predictors of early mastery versus error in children's acquisition of American Sign Language. Hypothesizes that the most frequent values for a particular parameter in prelinguistic gesture will be the most frequent in early signs and the most likely sources of substitution when children make errors. (Author/VWL)

Investigated the picture naming skills of dyslexic children, poor comprehenders and children with normally-developing reading skills, using pictures with names that varied in word length and frequency. Relative to young children reading at the same level, dyslexic children were less accurate naming pictures that have long names, and they made a…

Reductions and timing errors were 2 major signing disruptions observed in a 64-year-old deaf signer with Parkinson's disease; these errors are phonetic rather than phonological in nature. Error analysis yields information about sign prosody and American Sign Language phonological representation. (Contains 54 references.) (JP)

A study of Hans Christian Andersen's diaries from age 20 to age 70 found that his mean error spelling percentages are equal to contemporaries, but between 2 and 15 times lower than individuals with dyslexia. A structural analysis indicates that the proportion of plausible/implausible errors match those of normal achievers. (Contains references.)…

To examine possible explanations of reported inaccuracies of children with specific language impairment (SLI) on nonword repetition, study compared repetitions of 54 SLI children and peers for number and type of error, latency, and duration of response. Found no evidence of differences between groups in auditory discrimination or response…
