The relationship between intellectual function and adult performance on the Benton Visual Retention Test

The focus of the investigation was the relationship between intellectual function, as measured by the Satz-Mogel WAIS-R, and performance on the Benton Visual Retention Test. One hundred and twenty subjects, aged 18 to 30 years, were divided, 20 each, by IQ level into groups ranging from Mentally Retarded to Superior. Subjects provided both Number Correct and Error Score performances under conditions of immediate (Administration A, Form C), 15 s delay (Administration D, Form D), 30 m delay (Form E-card 2, 6, and 10), and copy (Administration C, Form C). Significant group differences were evident at all three conditions, primarily at the lower IQ ranges. Performances of the Average, High Average, and Superior IQ groups differed little, suggesting a ceiling effect. Significant decrements is performance under 30 m delay were evident only within the Low Average, Average and Superior IQ groups. Finally, normative performances under Administration C (Copy, Form C) and a quantitative assessment of errors (Administrations A and D) were reported.
