Spatial Imagery and Linguistic Processes in Deductive Reasoning in the Mentally Retarded Child. Final Report.
Anderson, J. Warren; And Others
Data were obtained on the reasoning processes of 92 normal seventh graders (IQ range, 90-130), 14 adjusted seventh graders (IQ range, 70-90), and 54 educable mentally retarded (EMR) junior high students (IQ range, 55-80) to determine whether spatial imagery differentially influenced the solution of three-term series problems, to determine the relative difficulties of three-term series problems as a function of age, sex, verbal IQ, and nonverbal IQ, and to determine whether the directionality preferences of mentally retarded subjects were related to their specific reasoning errors. Explained were factors to be considered in the study of deductive reasoning and the predictive ability of isotropic theory, theory of spatial paralogic, theory of spatial images, and deep structure theory. Findings indicated that instructions to use spatial imagery in problem solving systematically facilitated problem solution for the adjusted subjects. On the average, each of the 54 EMR subjects used four categories for spatial assignments so that prediction of series problem errors from spatial assignments was severely handicapped. Absolute errors were generally greater for subjects who had lower verbal IQ scores. No consistent differences in absolute or relative errors resulted when age was used to organize the data. (GW)
