title: WAIS-IV administration errors: effects of altered response requirements on Symbol Search and violation of standard surface-variety patterns on Block Design.
abstract: This study utilized a sample of 50 college students to assess the possibility that responding to the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) Symbol Search subtest items with an "x" instead of a "single slash mark" would affect performance. A second sample of 50 college students was used to assess the impact on WAIS-IV Block Design performance of presenting all the items with only red surfaces facing up. The modified Symbol Search and Block Design administrations yielded mean scaled scores and raw scores that did not differ significantly from mean scores obtained with standard administrations. Findings should not be generalized beyond healthy, well-educated young adults.
