ABSTRACT Although the availability of the computer-based assessment has increased over the years, neuropsychology has not carried out a significant paradigm shift since the personal computer’s popularization in the 1980s. To keep up with the technological advances of healthcare and neuroscience in general, more efforts must be made in the field of clinical neuropsychology to develop and validate new and more technology-based instruments, especially considering new variables and paradigms when compared to paper and pencil tests. Objective: This study’s objective was to produce concurrent validity evidence of the novel version of the computerized cognitive screening battery CompCog. Methods: Participants performed a traditional paper and pencil neuropsychological testing session and another session where CompCog was administrated. The data of a total of 50 young adult college students were used in the analyses. Results: Results have shown moderate and strong correlations between CompCog’s tasks and their equivalents considering paper and pencil tests. Items clustered in agreement with the subtest division in a principal component analysis. Conclusions: The findings suggest that CompCog is valid for measuring the cognitive processes its tasks intend to evaluate.

The current project is a preliminary attempt to compare an avatar administered virtual reality Stroop task (VRST) to standard (human) administration of the Stroop task. The avatar administered Stroop is part of a larger battery of tests aimed at proffering a cognitive screening battery that can be used in teleneuropsychology. The three versions of the Stroop task were administered to a sample of 66 healthy university students (64% female), between the ages of 19 and 27 years, which included equivalent distributions of men and women from ethnically-diverse populations. No significant differences were found for age, gender, or education. Results indicated that the typical Stroop effect pattern found in the human administered Delis– Kaplan Executive Function System and Automated Neuropsychological Assessment Metrics occurs in the avatar administered Stroop. We conclude that while the avatar administered Stroop has the potential to offer a novel approach to assessment of supervisory attentional processing, there are human factors issues that need to be addressed.

Neurologists often struggle to interpret the results of neuropsychological testing, even though cognitive assessments are an integral component of the diagnostic process in dementia syndromes. This article reviews the principles underlying clinical neuropsychology, background on common neuropsychological tests, and tips on how to interpret the results when assessing patients with dementia. General cognitive screening tools, appropriate for use by general neurologists and psychiatrists, as well as specific cognitive tests examining the main cognitive domains (attention and orientation, memory, visuospatial function, language and executive function) in patients with dementia are considered. Finally, the pattern of deficits, helpful in defining clinical dementia phenotypes and sometimes in predicting the underlying molecular pathology, are outlined. Such clinicopathological associations will become invaluable as disease-modifying treatments for dementia are developed and implemented.

Abstract Objective The objective of this study was to examine satisfaction, test anxiety, and performance using computer-based cognitive batteries versus a paper-and-pencil neuropsychological battery among older Blacks. Method Self-identified Black adults (n = 87, age range: 55–86; mean education = 14) completed two computer-based tests (CogState and Joggle) and a paper-and-pencil neuropsychological battery. After each battery, participants reported their testing anxiety and satisfaction using the batteries. Descriptive, correlational, and regression analyses compared satisfaction, anxiety, and performance across the batteries. Results Majority of the participants reported more satisfaction with the computer-based (Joggle: 66%; CogState: 77%) than the neuropsychological (52%) battery. Participants also reported less testing anxiety after completing the computer-based batteries than the neuropsychological battery, F(2, 172) = 22.96, p < .001. Older adults’ familiarity and comfort level with the computer were not associated with their performance on the computer-based tests (p > .05). Although testing anxiety was not associated with performance across the batteries, age and education quality were uniquely associated with performance on the CogState and neuropsychological batteries. Conclusions Computer-based cognitive batteries appear to be less intimidating than the commonly used paper-and-pencil neuropsychological tests for Black adults. Thus, these cognitive batteries may be useful tools for monitoring older Blacks’ cognitive status.

The purpose of this paper is to determine the individual relations between APEA and specific soils and environmental factors. To disclose these relations, analysis of component vectors and principal component analysis (PCA) were performed. Vectors of soil characteristics with participation of APEA (aAKFE) and vectors of pedochemical variables (aCHEM) were also calculated. Their ratio (ia) indicated the relative size of the APEA impact on the relations between pedochemical characteristics. Based on the statistical analyses, different role of APEA in Norway spruce and in European beech stands was detected. While APEA in spruce stands did not show significant correlations with the other examined soil chemical properties, soils under beech stands displayed strong correlations with some of the pedochemical variables. The idea of this research is to find out whether APEA could be used as an indicator of forest vegetation status and of the anthropogenic load on a site.

The Impact

The scope of this study is based on the Situational Leadership Theory according to the model created by Hersey and Blanchard, predominantly defined by two research sub-fields: leadership style and readiness of employees. This model distinguishes four different leadership styles, while the subject area of readiness of employees comprises two components: readiness of employees based on the competency component and readiness of employees based on a psychological (motivational) component. The subject matter of the study is to identify leadership style as a new variable which will be utilized for determining the interdependence with leadership efficiency levels and readiness of employees. Leadership efficiency is determined by the degree of compatibility between the dominant style of leadership and the level of readiness of employees. In addition to the main objective of the research, aimed at determining leadership efficiency, significant research findings come as a result of specific objectives. That is impact of the dominant leadership style on readiness of employees and leadership results, based on each specific component. The sample will be a random sample from a finite population of units, with repeated sampling and known probability sampling. A sample of size n=100, with a proportion of 0.10, is based on a list of top 100 biggest companies in the Republic of Serbia in 2019. The application of Principal Component Analysis aims to identify new variables in the form of regression coefficient results, while the application of the hierarchical regression model will help determine the impact of each leadership style on readiness of employees. The study findings confirm the basic hypotheses of the aforementioned model, with regard to the results of leadership efficiency, as well as its impact of each leadership style on readiness of employees.
