PROBLEMResearch with the earlier Wechsler-Bellevue I (W-B I) earned widespread acceptance for the WAIS even without the completion of test-retest reliability studies. When he presented the reliability of the WAIS, W e~h s l e r '~, P P . 12-18; P P . 101-103) reported (1) the standard error of measurement; (2) the intercorrelations among subparts of the total scale; and (3) split-half reliabilities. He found high reliability on these three indices for the Verbal, Performance, and Full Scale IQs. However, none of the above techniques measure stability of scores over time, nor do they indicate the size of gain t o be anticipated, in a normal population, from readministration.Although there is still a dearth of data that measure test-retest reliability of the WAIS, six test-retest reliability studies of the Wechsler-Bellevue I were found in the literature and have been reviewed by Matarazzo(5). One of these, conducted by Derner, Aborn and Canter (*), was a large-scalc rrliability study that compared normals retested after 1 week, 4 weeks and 6 months. The retest correlations for VIQ, PI&, and FSIQ were 3 4 , .86, and .90, respectively. Time interval affected the size of practice gains, and memory factors apparently played a significant role in size of gain over relatively brief intervals.Planned test-retest reliability studies of the full WAIS have not yet appeared, although two studies present some WAIS test-retest data. &Jeer and Baker(6) tested 77 geriatric patients on 4 subtests (Information, Comprehension, Arithmetic, and Digit Span) and retested them 24 hours later. The reliability coefficient for the pro-rated FSIQ (total scaled score) was .96 for both sexes. Subtest correlations for males ranged from .81 (Digit Span) to .97 (Information). The female data were similar.As a byproduct of a longitudinal study, Iiangas and Bradway(4) present the WAIS test and retest scores of 48 normals, examined 13 years apart (at ages 29 and 42). The Full Scale WAIS reliability coefficient was .73; Verbal Scale .70; and Performance Scale .57. The mean gain in Full Scale IQ was approximately 9 points and was found to be related to sex and initial I&. Men of high I& showed the largest increase, whereas women of high and medium I& earned the least increment. The authors conclude that there is continued, slow mental growth between the ages of 30 and 44.This study investigated WAIS test-retest reliability among a sample of 29 normal, young adult men over a retest period of 3 to 5 months. A second purpose was to present normative individual test and retest scores for all subtests and total scales, mean and median gain scores, range of gain and loss, and test-retest reliabilities of the individual subtests. These data will provide the clinical practitioner with at least a small sample of normal Ss with whom it will be possible to compare clinical retest scores.

PROBLEMInvestigators long have sought empirical evidence that speech behavior mirrors underlying motivational state. I n previous studiee". we have presented indirect evidence that speech reflects some elements of an interviewee's present state. In the first study, job applicant interviewees, when discussing in one 45-minute interview their own Education (Ed), Family (Fa), and Occupational (Oc) backgrounds, differentially responded to the content area (Oc), presumed to be the most important (salient) of the three for them in these real life employment interviews. In the second study, using the same three content areas, four groups of college student interviewees responded differentially to the education content area. I n both studieq Ss spoke significantly longer and with sigmficantly shorter latencies in the content area believed to have the most personal import (saliency).Because these cross-validated findings suggested that discussion of some content areas has differential importance for S as a result of his current psychosocial state, we began both (a) to think of such s t a h as more "salient" than those vrhis reaearch was canied out in conjunction with support frum the otfice of Scientific l-arch office of Aempace Reeearch, United States Air Force, under AFOSR Grant Number 129747, and Gnmt Number XG-3057.
