A comparison of borderline and mild mental retardates assessed on the memory for designs and the WAIS-R.

A matched group (N = 114) between high errors and no error conditions on the MFD was examined in a population of borderline and mild mental retardates. Matched variables were sex, Full Scale IQ, and age. The MFD, PIAT, and the WAIS-R were administered to all subjects. Results on achievement tests showed that the mild mental retardation subjects with high errors on the MFD had lower achievement scores on the PIAT compared to the non-error group. The non-error group performed at a higher level on the Picture Arrangement, Vocabulary, Math, and Reading Comprehension. Borderline retardation subjects showed no significant differences between error and non-error groups on the PIAT and WAIS-R. These conclusions indicate that the MFD is a more sensitive indicator of intelligence differences than of organicity differences.

The principle of additivity and its relation to clinical decision making.

Clients (N = 178) with varying degrees of organic indicators were administered a psychological battery including the Memory for Designs Test (MFD; Graham & Kendall, 1960) to assess the extent to which joint presence of organic indicators affected the sensitivity of the MFD in identifying organicity. Joint presence failed to add to the discriminability of the MFD, although individual instruments such as the PIAT (Arithmetic) and WAIS-R (PIQ less than VIQ) clearly discriminated across the MFD.

Differential effects on verbal-performance achievement levels on the WAIS-R as a function of progressive error rate on the Memory for Designs Test (MFD).

One hundred seventy-eight subjects participated in a study to measure the degree of selective subtest decline on the WAIS-R as a function of increased error rate on the Memory-for-Designs Test. The data show that there is an initial, significant decline in the verbal knowledge component of the verbal scale as error rate on the MFD progresses. Performance factors are only significantly related to error rate on the MFD when the latter are maximized.

Interposition and size constancy: a developmental study.

27 children (mean age 6.7 yr.) and 84 adults (mean age 26.3 yr.) were asked to judge the sizes of human figures in photographs. Half the cards contained interpositional depth cues while the other half did not. Both groups of subjects showed better size constancy with interposition present than without it.
