HI-RO: A TEST FOR HEMISPHERE INPUT-RESPONSE ORIENTATION
Abstract
Differential use of the abilities and specializations of the hemispheres of the brain as revealed through brain research affects everyday living and working, learning and acting. Development of a test (HI-RO) for adults to identify their hemisphere orientation was the purpose of this study. Additionally, the viability of pictures in the test design was examined. Criteria for item construction were derived from brain research applied to life/learning situations. A pilot study with Draft One, the use of a panel for item selection for Draft Two, development of a third/final draft, and reliability and validity studies were presented in detail. In all, 350 adults were tested. The HI-RO test consists of 30 items, each offering three choices keyed to right-brain, left-brain, or interactive orientation. The data revealed a fourth orientation, a bi-modal pattern in which persons showed equal and greatest orientation toward two or more patterns. The stability of the test, estimated via a test-retest analysis, was .76, .88, and .86 for the right, left, and interactive scales, respectively. "Your Style of Learning and Thinking" (SOLAT), Form C, by Torrance and Reynolds was the external criterion for construct validity. In addition, the finding of differences in hemisphere orientation among occupational groups as postulated by research supported validity. Significant differences were identified on the right and left scales between means attained on HI-RO by 23 accountants, 27 architects, 40 artists, 18 attorneys, and 26 nurses and on the interactive scale between cultural groups (38 Native American and Hispanic adults and 125 Whites). By comparing scale selection for HI-RO picture/nonpicture items and for HI-RO picture items with a random selection of SOLAT nonpicture items, significant differences were found. Similarly, comparison of classification of persons by the SOLAT and HI-RO tests showed significant differences. These findings, together with evidence from brain research, led to the conclusion that a test with pictures has greater validity for identification of hemisphere orientation than a test without pictures. Implications of the study were discussed and further research was suggested.
