Identification of specific neurological disorders using double discrimination scales derived from the standardized Luria neuropsychological battery.

The Standardized Luria-Nebraska Neuropsychological Battery has been validated in a number of studies and has shown its effectiveness in making basic neuropsychological discriminations. A major advantage of this battery, compared to other test batteries, is its structure. The test consists of 269 separate items, each of which is designed to measure a different neuropsychological skill. As a result, these items can be combined in a number of ways to form scales aimed at specific neurological processes. It is the purpose of the present study to investigate whether or not the Luria Battery can be successful in discriminating specific neurological disorders by the development of what is termed "double discrimination scales." Using this process, two scales are established to diagnose any given neurological process. The first represents items in which the patients with a specific disorder do worse than a general neurological control group while the second scale represents items in which the patients with a neurological disorder do better than the general neurological control group. For a patient to be diagnosed as having a given process, the patient must score in the proper range on both scales. This method was applied to a sample of 24 multiple sclerosis patients who were compared with 74 patients diagnosed as normal, 106 psychiatric patients, and 101 brain damaged patients. Using the double discrimination procedure, the accuracy of identification of 100% was achieved in all groups. The study supported the usefulness of the double discrimination approach with the Standardized Luria Neuropsychological Battery and opens up the possibilities for scales to be developed for a wide variety of diseases in specific lateralized disorders.

The use of a standardized battery of Luria's tests in the diagnosis of lateralized cerebral dysfunction.

The present study was designed to examine the capability of a standardized battery of Luria's qualitative neuropsychological techniques in discriminating between right, left and diffuse brain-injured subjects. A total of sixty medically confirmed brain-damaged subjects were equally divided among the three groups. Subjects were assigned to two groups (right, left) according to medically proven lateralized brain injury to either the right or left hemisphere in the absence of verifiable insult to the opposite hemisphere. A third group was also selected in which medical evidence confirmed damage to both hemispheres (diffuse group). All three groups were matched for age and education. All subjects were tested on a standardized version of 269 Luria's qualitative neuropsychological test items. The items were divided into 11 sections based upon Luria's theory of brain function. Each of the 11 sections plus a right and a left hemisphere scale as well as an overall impairment scale yielded 14 summary measures of performance representing several areas of neuropsychological ability and overall severity of brain dysfunction. Analysis of variance and discriminant analysis were used to compare the three groups on these 14 summary measures. Analysis of variance revealed on significant difference between the three groups on the Left scale with the left group performing poorest. Discriminant analysis predicted the status of 59 of 60 subjects correctly (98% hit rate). The implication of the lack of significant simple relationships (ANOVA) and the complex interrelationships found using the discriminant analysis were discussed in terms of the support these results provide for Luria's theory of brain function. The specific qualitative aspects of the test battery and their use in the diagnosis of lateralized brain injury were also discussed. Indications for future research were pointed out.

Personality correlates of attitude toward death.

Examined the interrelationships of two scales of attitudes toward death with four measures of personality: the Manifest Anxiety Scale, the Novelty Experiencing Scale, the Marlow-Crowne Social Desirability Scale, and the Internal-External Orientation Scale. Ss were 142 volunteer males enrolled in introductory psychology courses. A correlation of .72 was found between the Death Concern Scale and the Death Anxiety Scale. In addition, both scales showed the same pattern of correlations with the four personality measures. The highest correlations were found between death attitude and the manifest anxiety scores and the external-internal orientation scores. The importance of including these factors when one is interpreting death attitude scores was stressed, as well as the need for research to establish that these scales measures an anxiety or concern above and beyond general anxiety.

Cross-cultural second order factor structures of the 16PF.

Cross-cultural personality research has generated a great amount of data on individual difference patterns in diverse cultures. One of the major instruments used in this research has been Cattell's 16PF. A major question in this research is whether the underlying personality structure is equivalent for different cultures. The present study evaluated the second order factor structure of the 16PF in 101 subjects of European ancestry and 117 subjects of Japanese ancestry. The factor structure for the Japanese was significantly different from that of the caucasian group. The caucasian results did not differ from those reported by Cattell and his associates. The implications of these results for personality theory and for cross-cultural evaluation were briefly discussed.

Short form of the Speech Sounds Perception Test.

Although numerous studies have investigated the diagnostic effectiveness of the Speech Sounds Perception Tests, few have investigated the qualities of the test make it effective. Different writers have suggested that it may be effective because of interference from earlier syllables and items, an inability to understand speech, fatigue or an inability to match letters and sounds. If the effectiveness is due to fatigue or interference, the lengh of the test (60 items) would contribute to its accuracy. Otherwise, a short form of the test could be as effective. Data from 37 brain-damaged and 21 normal individuals indicated that a 30-item version of the test was slightly more accurate diagnostically than the 60-item form. This suggests that a short form of the test could be used without sacrificing diagnostic accuracy, enabling the clinician to save time in assessing neuropsychological patients.

Higher cortical dysfunction associated with long term alcoholism.

A number of studies during the past decade have described deficits associated with chronic alcoholism. Although several of these studies have used neuropsychological tests, no study has comprehensively surveyed all recognized neuropsychological skills in a single population. The present study compared 41 chronic alcoholics to 41 matched controls during a two-day battery of neuropsychological tests, including the Halstead-Reitan, Wechsler Memory Scale, and other major tests. It was hypothesized that tests reflecting right and anterior brain function would differentiate between the groups. A factor analysis of the tests which differentiated between the groups indicated five primary deficits in chronic alcoholism: spatial conceptual skills, associative conceptual skills, flexibility, spatial-motor integration, and serial integration. The last factor demonstrated a small but significant verbal loss in the alcoholics. The implications of these factors for understanding and treating chronic alcoholism were discussed.

The identification of brain damage by an abbreviated form of the Halstead-Reitan Neuropsychological Battery.

In recent years there has been an increased interest in the development of neuropsychological tests that can diagnose accurately brain damage. The most successful of these test are represented in the Halstead-Reitan Neuropsychological Battery, which has been shown to be 90% or more effective in the diagnosis of brain damage. However, this battery is not available to many psychologists or clients because of its length, cost, and the considerable background required to use it properly. The present study tested 121 Ss (30 normal, 91 brain-damaged) to develop an abbreviated version of the battery that is relatively brief (1 hour) and inexpensive, but accurate. It was found by discriminant analysis that the abbreviated battery is capable of diagnosing brain damage equally as well as the full battery 93% of the time. The limitations and advantages of the abbreviated battery are discussed.

A group version of the Stroop Color and Word Test.

The uses of the Stroop Color and Word Test have been limited because of the lack of a standardized form, particularly one which could be used for both individual and group administrations as demanded by the requirements of a research project. The present version of the test counted the number of items completed by the subject in a 45-second time period. In the individual version the subject said the words out loud while in the group version he said the words to himself. Results indicated that the two versions were equivalent to each other as well as to forms requiring the subject to read a whole page of items. It was felt that a group form would greatly enhance the research capabilities of the Stroop Test.

The measurement of creativity by the Stroop Color and Word Test.

The development of a valid and reliable measure of creativity has been a challenging problem to psychologists. Gamble and Kellner (1968) have suggested that the Stroop Color and Word Test (SCWT) might be such a measure. The advantages of the Stroop include that it tests basic processes, is stable over long periods of time, and is easy to administer and score. The present study investigated the relationship of the Stroop to three independent measures of creativity: a verbal task, a nonverbal task, and ratings by teachers. In all cases a significant relationship was found between these measures and the Stroop interference score. A concept of creativity as a basic underlying process is discussed by the author as well as implications for further research.
