A comparison of the scores on the Spearman visual perception test, Part I, administered by verbal and pantomime directions

The correlation of the Spearman visual perception test, part I, with CAVD scores was .58 when pantomime directions were used and .48 when verbal directions were used. The mean Spearman test score was significantly lower when pantomime was used. Since the difference between the r 's with CAVD was not significant, and the reliability of the Spearman scores was not changed when pantomime directions were given, it is concluded that pantomime and verbal directions give results similar in reliability and validity.
