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)

This paper examines the tacit assumptions behind different theories about the nature of language and aphasia, and it discusses critically the use of structural and generative linguistic theories to explain the behavior of aphasics, especially with regard to the difference between spoken and written discourse. It is proposed that, rather than try…

The purpose of this study was to replicate the Bentti, Golden, and Reigeluth study (1983), which explored the use of nonexamples to teach common errors as an effective strategy in teaching a procedure. A total of 24 undergraduate students enrolled in the Syracuse University Symphonic Band were randomly assigned to an experimental group and a…

This study was designed to test the hypothesis that students who are given common errors matched with correct performance as part of their instruction in carrying out a procedure will perform better than students who are given only the correct performance. The task was the procedure for correcting color imbalances in color slides, and 56 college…

Presents five simulation models reflecting sequential levels of children's simple arithmetic story problem solving skills. Outputs of the models are compared with data obtained by presenting 60 five- to eight-year-olds with change problems to examine models' deterministic nature. Results indicate the models give an adequate description of behavior…

The study was undertaken to investigate the errors made by high and low achievers in a mathematics test administered to students in their second year of high school. The focus of the study was to determine whether any common error types existed within or between the two groups or whether there were error strategies which differed between the two…

A study of overt audible speech behavior in eight male and one female Swedish adults examined the relationship between disfluency and speaking modality, disfluency type in mild versus severe stutterers, and disfluency and psycholinguistic variables. Three conditions of experimental manipulation were used: reading aloud, reading the longer lines of…

One limitation of hired farm labor data from the Decennial Census is undercounting; the seasonal nature of farm work means that many farm laborers are not employed in March, when the Census is taken. The 1981 Hired Farm Working Force Survey provided data to evaluate the usefulness of Census data for farm labor research. Data were grouped into…
