Constructing Local Age Norms Based on Ability for the Bender-Gestalt Test

Abstract

The purpose of this study was to examine developmental patterns in visuomotor functioning across age and ability groups. A second purpose was to develop local norms to allow practicing psychologists to examine relative differences within age and IQ groups in visuomotor performance. Thus, an age-by-mental ability normative data set ( N = 4,014) was constructed from archival records from 10 public school systems and analyzed to identify both qualitative and quantitative differences in visuomotor functioning for children between 6 and 18.11 yr. of age across 9 IQ levels ranging from 40 to 129.
