Order of item difficulty on picture arrangement: data from a normal elderly sample.
In a sample of 226 normal elderly persons the order of item difficulty for the WAIS-R Picture Arrangement subtest was examined. Means for age and education were 80.8 yr. (SD = 5.2) and 10.9 yr. (SD = 2.9), respectively. The current order of items does not conform to the expectation of increasing difficulty. When testing elderly persons, intrasubtest scatter on Picture Arrangement should not be used to infer pathology.
