A Comparison Of The Illinois Test Of Psycholinguistic Abilities And The Parsons Language Sample In Assessing The Linguistic Functioning Of Institutionalized Mentally Retarded Children, Ralph Donald Lee Horner
Electronic Theses & Dissertations
The purpose of this research was to compare the Illinois Test of Psycholinguistic Abilities and the Parsons Language Sample in assessing the linguistic functioning of institutionalized mentally retarded children. A stratified sample of mentally retarded children was administered both the ITPA and PLS in counterbalanced order. The results were correlated through the Pearson product-moment correlation coefficient and the correlation matrix analyzed through a principle-components factor analysis. The ITPA, PLS comparison produced high correlation coefficients with the exception of the Intraverbal Gesture sub-test of the PLS. The factor analysis of the correlation matrix revealed one or more sub-tests had high loadings …

Errorless Establishment Of A Right-Left Discrimination In Retardates, Judith Marie Leblanc
Electronic Theses & Dissertations
This study was concerned with the task of determining necessary steps for establishing an errorless method of discrimination training in a right-left problem. It was designed to establish a terminal motor response of the S placing the "correct" hand on a blank stimulus board in response to an auditory stimulus of "Left" or "Right." To achieve this terminal response in a group of institutionalized retardates, stimuli of a previously learned color discrimination (pink and blue) were presented immediately following the corresponding auditory stimulus of "Left" or "Right" during each of the initial discrimination trials. To preclude or greatly diminish errors …
