The present study was designed to assess the role of response time on the Category Test of the Halstead-Reitan Neuropsychological Test Battery (HRNB). The intent was to define the underlying constructs of the Category Test more particularly, the speed of performance by examining response time to individual slides of the Category Test.Seventy-two normal adult volunteers were administered the complete HRNB. Average response times were computed for correct (CRT), incorrect (IRT), and total (TRT) scores on the Category Test. The efficacy of using response measures (CRT, IRT, and TRT) to predict Category performance was examined in the context of other HRNB variables that loaded factorially with the Category Test, more specifically: TPT-time, memory, and location, Trails B, WAIS-R Block Design, and WAIS-R Object Assembly.A step-wise multiple regression analysis was computed using the above HRNB and response time measures to predict Category error scores. Results from this analysis indicated that TPT-location, TRT, and IRT contributed significantly (p<.05) in the prediction of Category scores. Approximately 15% of the variability in Category scores was explained by a measure of spatial memory (TPT-location) and an additional 15% was accounted for by psycho-motor speed (TRT and IRT). The significant contribution of response time in defining the underlying construct of the Category Test was discussed in terms of possible implications for enhancing the neuropsychological significance of the Category Test.

The problem of this study was to isolate General Aptitude Test Battery patterns for persons who have succeeded in certain major fields of study at North Texas State University, Denton, Texas. In addition to the basic problem stated above, an effort was made to (1) determine the significance of the relationships between GATB scores and grade-point averages for all undergraduate courses taken; (2) determine the relationships between GATB scores and grade-point averages for all undergraduate courses in the major field of study, and (3) conduct a survey of all subjects selected for this study to determine their past, present and expected future fields of occupational endeavor since graduation from college and the relationship between such employment and the individual's major field of study in college.

As new measures of aptitude are devised, their implications to education are a fertile source for research. All facets of aptitudes as they relate to education are explored. This study is concerned with such exploration in that it investigates the relationships between aptitudes, as measured by the General Aptitude Test Battery and selected major fields of study at North Texas State College, Denton, Texas. The major fields of study selected for this research are Accounting, Business Education, Elementary Education, Industrial Arts and Marketing.

The advantages of administering an adaptive test battery, a collection of multiple adaptive subtests that are specifically tailored to examinees’ abilities, include shortening the subtest length and maintaining the accuracy of individual subtest scores. The test battery can incorporate a range of subjects, though this study focused primarily on Math and Reading. This study compared different ways of incorporating collateral information (CI), supplementary information beyond examinees’ current test performance, under two frameworks (Unidimensional and Multidimensional computerized adaptive testing). It also investigated the impact of subtest intercorrelations (the relationship between an examinee’s test scores), as well as the sequences of subtest administration on ability estimation in a variable-length adaptive battery. Practical issues including content constraints and item exposure control were also considered. Findings showed that the CI methods improved measurement efficiency with an acceptable level of measurement precision. The CI was more beneficial when associated with higher intercorrelations among the subtests. Also, the CI was found to be advantageous during the early stages of the subtests which were not taken first. Therefore, the CI may improve the examinee experience by administering items more aligned with their abilities. In addition, the CI should reduce costs for testing organizations by requiring fewer items and possibly saving seat time, while still providing reliable scores. The results should help practitioners decide whether the use of the CI is worthwhile under their particular testing situation.

The primary purpose of this study was to determine the kind of neuropsychological information that can be obtained from an investigation of the Wechsler Adult Intelligence Scale (WAIS) subtests. Additionally, there was an examination of the shared variance between the WAIS and the Halstead-Reitan Neuropsychological Battery (HRNB). The archival data collected from the files of '220 females and 188 males from a large midwestern medical center were used. They had been originally diagnosed with objective research criteria.All eleven subtests of the WAIS and the HalsteadReitan Neuropsychological Battery were administered to the subjects in the years between 1981 and 1983. Thirteen scores were obtained from the HRNB measures. Statistical analyses of the results made use of the techniques of multiple regression and canonical correlation.The individual WAIS subtests were examined for the neuropsychological information they provided. Globally, three HRNB measures, APHASIA, RHY, AND CAT-TOT contributed significantly to a majority of the regression equations for the WAIS subtests. Their presence suggested that language skills, an auditory attention factor, and a general intellective factor were being tapped (Dean, 1985a).A canonical correlation was computed. The results yielded one significant correlation between the linear components of the WAIS and the HRNB tests. Only canonical variates with weights of +/- .2 were considered large enough for interpretation. The WAIS subtests meeting the .2 criteria included Block Design, Digit Symbol, and Similarities, while the HRNB measures meeting criteria were APHASIA and CAT-TOT. Therefore, it would appear that the significant variables measured the general (g) factor as in Spearman's research (1927). According to the Stewart and Love formula (cited in Pedhazur, 1982), the variability of the WAIS did overlap with the HRNB, and their relationship was symmetrical.This research demonstrated that the measured tasks from the WAIS were a complex of underlying constructs. The verbal portion of the WAIS was shown to be less highly related to the HRNB variables than the performance portion of the scale. The WAIS and HRNB do offer nonredundant information concerning the impaired and unimpaired adult's cognitive functioning.
