Predicting closed head injury status with the Dean-Woodcock Sensory Motor Battery

Budenz-Anders, Judey January 2006 (has links)
The purpose of this study was to examine the utility of the Dean-Woodcock Sensory Motor Battery (DWSMB) as a diagnostic tool for identifying individuals with and without closed-head injury, comparing the predictive power of a two- and three-factor representation (DWSMB; Dean & Woodcock, 2003). The current study's major research questions focused on the predictive utility of the structure of the DWSMB. The simplified two-factor model (Total Sensory and Total Motor), based on the DWSMB manual (Dean & Woodcock), was compared to a three-factor theoretical model (Basic Sensory, Higher Sensory and Motor Functions) (R.S.Dean, personal communication, March 29, 2006) for this study. Logistic Regression was used to analyze the data. Results from this study demonstrate that when using the two-factor solution, the overall correct prediction of group membership was 73.8 % (59.4% for CHI and 85.2% for normals). The Total Motor Impairment variable was the only meaningful predictor. The results from the three-factor solution show an 84.2 % overall correct prediction rate (71.4 % for CHI and 95.1 % for normals). The significant contributors for identifying CHI when using the three-factor model included Basic Sensory and Motor Functions. Everything favors the three-factor model as being more precise. All indicators of prediction accuracy and goodness of fit favored the three-factor model. Based on these results, the DWSMB was determined to be a good screening instrument for identifying children in school contexts who should be referred for a neuropsychological examination to confirm pre-existing CHI that interfere with school functioning. / Department of Educational Psychology

Development and decline of sensory and motor skills in a normative sample / Sensory and motor skills

Whited, Amber R. 24 January 2012 (has links)
This cross-sectional study evaluated the trend in sensory and motor skill development for an archival dataset used in the standardization of the Dean-Woodcock Sensory Motor Battery (D-WSMB). Measures from the D-WSMB were organized into three broad categories according to a factor model identified by Davis, Finch, Dean and Woodcock (2006). Three primary hypotheses were evaluated: a confirmatory factor analysis would support the Davis et al. model for the current dataset, performance on sensory and motor tasks would exhibit a pattern of development and decline across age levels, and gender would not be a significant factor in variability in performance. CFA results indicated the Davis et al. factor model was a poor fit for the current dataset but that each measure loaded significantly on the factor to which it was assigned. Curve estimation identified a significant quadratic relationship between age and performance on each of the skill categories. A significant age and gender interaction was noted for each skill category. The statistically poor fit of the Davis et al. factor model was thought to be due to potential correlations between factors and between measures within the factors, although further research is needed to evaluate the impact of these relationships on model fit. Results confirmed the hypothesis that sensory and motor skill exhibit a pattern of development and decline across age levels, which can guide the interpretation of performance in a clinical setting. Further research is needed on the nature of the age and gender interaction to clarify the impact on performance on measures of sensory and motor skills. In an addendum to this study, performance on individual measures of the D-WSMB was plotted to provide further guidance in the interpretation of results in clinical settings. / Department of Educational Psychology

The neuropsychology of autism and Asperger's disorder : evidence for or against a shared spectrum

Neal, Tiffany J. 03 May 2014 (has links)
Given the broad public health concern, lack of reliability of diagnosis across providers and substantial resources needed to support individuals with Autism Spectrum Disorder, the current study serves to contribute to the field in informing the contexts of both research and clinical service. The utility of a standardized sensory-motor battery was investigated in regards to its ability (1) to determine what, if any, differences exist between ASD diagnoses or subgroups in both sensory functioning and motor functioning; and (2) to determine whether such discrepancies, if they exist, are capable of differentiating groups. Results from the quadratic discriminant analysis demonstrated that the factor scores derived from the Dean-Woodcock Sensory-Motor Battery significantly differentiated the ASD and nonclinical comparison groups. Factor 1 (Simple Sensory Skills) exhibited the strongest relationship, followed by Factor 2 (Cortical Motor and Complex Sensory Skills), then Factor 3 (Subcortical Motor Tasks and Auditory/Visual Acuity Skills). Findings from the study lend initial evidence of the use of the DWSMB as a potential measure to include within the two-stage diagnostic process for ASD. Use of the DWSMB as a screening measure may facilitate access to early intervention services given the primitive nature of sensory-motor tasks. In addition, the availability of the DWSMB as a standardized measure of sensory and motor functioning may promote increased sensitivity and specificity among diagnostic providers thus improving outcomes of individuals with ASD who can access services more readily with earlier, more reliable diagnoses. / Access to thesis permanently restricted to Ball State community only. / Department of Educational Psychology

A failure in this kind of system can be catastrophic. For example, it can harm human lives or increase project budgets. Hence, the testing of real-time systems must be accurate. Models are used to perform this task, since they contain information about how the system behaves and when actions may happen. Due to the complexity of the available systems, most RTS are composed of subsystems that interact as part of a bigger system. These subsystems are combined through operators to model their specification behavior. However, works on the testing of compositional models for RTS are practically nonexistent. Among the available approaches to perform testing for non-compositional RTS models, the tioco conformance testing theory focuses on generating test cases based on implementation and specification models. Moreover, a conformance relation defines whether success in testing means conformance between an implementation and a specification. To express specifications and to represent implementations under test, we use Timed Input Output Symbolic Transitions Systems (TIOSTS). These models store symbolic data and clock variables, avoiding the state space and region explosion problems. Regarding the testing of compositional models, some questions may arise: If two subsystem implementations are tioco conformant to their specifications, is it correct to assume that the composition of the implementations is also tioco conformant to the composition of their specifications? In this case, how can operators be defined to work with TIOSTS and tioco? To answer these questions, this thesis proposes the sequential, interruption and parallel operators for the TIOSTS model. For each operator, we study how the tioco conformance relation behaves with respect to subsystems and the composed system. We present results towards properties of compositional operators when the subsystems are composed, as well as implementing them. Besides, we show three examples where each operator can be used and illustrate the applicability of our approach in two exploratory studies.

Prediction of Extrapyramidal Effects of Neuroleptic Therapy Using Visuomotor Tasks

Hopewell, Clifford Alan 05 1900 (has links)
The present study attempted to predict the serious side effects of akathisia and parkinsonism on the basis of individualized measurement of changes in visuomotor functioning. The following were the hypotheses for this investigation. 1. A deterioration of visuomotor ability as measured by a modification of Haase and Janssen' s (1965) Handwriting Test will predict which patients undergoing neuroleptic therapy will experience the extrapyramidal symptoms of akathisia and parkinsonism (symptom group) and which will not (no-symptom group). 2. A deterioration of visuomotor ability as measured by the Bender-Gestalt will predict which patients undergoing neuroleptic therapy will experience the extrapyramidal symptoms of akathisia and parkinsonism (symptom group) and which will not (no-symptom group). It was not possible to predict the symptom group as a whole on the basis of the Handwriting Test scores since a t test of the difference was not significant between group means. However, inspection of these scores showed clear deterioration of performance among the patients who experienced parkinsonian reactions as opposed to those who experienced akathisia or who did not experience extrapyramidal symptoms at all. The symptom group was separated into akathisic and parkinsonian groups and compared to the subjects who did not experience extrapyramidal side effects (no-symptom group). A one-way ANOVA showed a nonsignificant difference between the three groups. Similar analysis of the Bender-Gestalt scores failed to support the second hypothesis since no significant difference was found between groups.

Mutação de interface: um critério Interprocedimental para o teste de integração / Interface mutation: an interprocedural adequacy criterion for integration testing

Márcio Eduardo Delamaro 17 June 1997 (has links)
Um dos pontos fundamentais na atividade de teste de software é o projeto de casos de teste. Diversos critérios de adequação têm sido propostos com o objetivo de fornecer meios que permitam que a avaliação e elaboração de casos de teste sejam feitas de maneira sistemática e fundamentadas teoricamente. Infelizmente, a maioria dos critérios de adequação de casos de teste definidos tem seu uso restrito ao teste de unidade. Para fases posteriores da atividade de teste, em particular para o teste de integração, nota-se a ausência de critérios de adequação, principalmente porque os critérios propostos definem requisitos de teste que se restringem aos limites de uma única unidade, não exercitando de maneira efetiva as interações entre as unidades, que devem ser alvo principal no teste de integração. Com exceção de alguns poucos trabalhos que procuram estender critérios estruturais para o nível interprocedimental, tem-se utilizado nessa fase de teste, quase que exclusivamente, critérios funcionais. Dada essa ausência de critérios e salientando ainda o caráter complementar entre as diferentes técnicas de teste, esta tese apresenta um critério de teste interprocedimental baseado em defeitos chamado de Mutação de Interface. Esse critério busca exercitar as interações entre as unidades através da seleção de casos de teste que distingam mutantes criados pela introdução de defeitos típicos e que, de acordo com um modo definido, caracterizamos erros de integração. Definiu-se um conjunto de operadores de Mutação de Interface que concentram sua aplicação em pontos do programa relacionados com as interações entre as unidades, como, por exemplo, chamadas de subprogramas e seus parâmetros. Dados o alto custo de aplicação, inerente de critérios baseados em mutação, e pelas próprias características do conjunto de operadores de Mutação de Interface, torna-se necessário definirem-se abordagens para reduzir esse custo. Assim, foram estabelecidas maneiras de se parametrizar a aplicação dos operadores de mutação, definindo-se critérios de Mutação de Interface alternativos, estendendo-se abordagem sutilizadas no teste de mutação convencional como mutação restrita. A aplicação de um critério de teste está fortemente condicionada à sua automatização. A definição de um critério de teste sem que pelo menos se apontem soluções para sua automatização tem pouca utilidade prática. Por isso, especificou-se e implementou-se a ferramenta PROTEUM/IM para apoiar a aplicação do critério Mutação de Interface. Essa ferramenta torna-se essencial neste trabalho à medida que permite que estudos empíricos possam ser realizados, avaliando o critério proposto. Dois estudos de caso são apresentados. Esses estudos aplicam o critério Mutação de interface em programas reais e buscam avaliar seu custo e sua eficácia em revelar erros. Estes estudos aplicam ainda critérios alternativos, mostrando que a Mutação de interface é bastante efetiva em revelar erros o de ter custo de aplicação bastante reduzido, quando aplicada de maneira incremental, utilizando-se as parametrizações que os operadores de mutação oferecem. / The project of test cases is one of the most important topics in the software testing activity. Several criteria have been proposed aiming at allowing the evaluation and selection of test cases in a systematic and theoretically well founded way. Unfortunately, the use of most of these criteria is restricted to the unit testing phase. For other testing phases, in particular for integration testing. there is a lack of such criteria, mainly because the existing criteria define test requirements only in the scope of a single unit. They arc not able to effectively exercise the interactions between units, what should be the focus of integration testing. Excepting some few works that extend structural criteria to the interprocedural level, only functional testing has been used at integration testing phase. Given this lack of criteria and the complementary characteristics of different testing techniques, this thesis presents an interprocedural fault based criterion named Interface Mutation. This criterion exercises the interactions between units through the selection of test cases that distinguish mutants created by introducing typical faults that characterize integration errors. A set of Interface Mutation operators was defined. The focus of these operators are the points of the program related to the unit interactions, for instance, subprogram calls and their parameters. Given the high cost associated to mutation testing in general and particularly to the Interface Mutation operators, it is necessary to define some approaches to reduce its application cost. Thus, some parameterizations were defined to the mutation operators, allowing to establish alternative Interface Mutation criteria, extending approaches already used in conventional mutation testing, as random mutation and constrained mutation. The application of any testing criterion strongly depends on its automatization. The definition of a criterion, without pointing out ways to its implementation has little practical utility. So, a tool named PROTEUM/IM was specified and implemented to support the application of Interface Mutation. This tool is an essential point in the present work because it allows the conduction of empirical studies aiming at evaluating the proposed criterion. Two case studies arc presented. In these studies the criterion Interface Mutation is applied to real programs and the cost of its application as well as its errors revealing effectiveness are evaluated. Alternative criteria are also used. Showing that Interface Mutation is very effective to reveal errors and can be applied with a reduced cost if used in an incremental way, taking advantage of the parameterization characteristics provided by the Interface Mutation operators set.

Uma contribuição para a minimização do número de stubs no teste de integração de programas orientados a aspectos / A contribution to the minimization of the number of stubs during integration test of aspect-oriented programs

Reginaldo Ré 31 March 2009 (has links)
A programação orientada a aspectos é uma abordagem que utiliza conceitos da separação de interesses para modularizar o software de maneira mais adequada. Com o surgimento dessa abordagem vieram também novos desafios, dentre eles o teste de programas orientados a aspectos. Duas estratégias de ordenação de classes e aspectos para apoiar o teste de integração orientado a aspectos são propostas nesta tese. As estratégias de ordenação tem o objetivo de diminuir o custo da atividade de teste por meio da diminuição do número de stubs implementados durante o teste de integração. As estratégias utilizam um modelo de dependências aspectuais e um modelo que descreve dependências entre classes e aspectos denominado AORD (Aspect and Oriented Relation Diagram) também propostos neste trabalho. Tanto o modelo de dependências aspectuais como o AORD foram elaborados a partir da sintaxe e semântica da linguagem AspectJ. Para apoiar as estratégias de ordenação, idealmente aplicadas durante a fase de projeto, um processo de mapeamento de modelos de projeto que usam as notações UML e MATA para o AORD é proposto neste trabalho. O processo de mapeamento é composto de regras que mostram como mapear dependências advindas da programação orientada a objetos e também da programação orientada a aspectos. Como uma forma de validação das estratégias de ordenação, do modelo de dependências aspectuais e do AORD, um estudo exploratório de caracterização com três sistemas implementados em AspectJ foi conduzido. Durante o estudo foram coletadas amostras de casos de implementação de stubs e drivers de teste. Os casos de implementação foram analisados e classificados. A partir dessa análise e classificação, um catálogo de stubs e drivers de teste é apresentado / Aspect-oriented programming is an approach that uses principles of separation of concerns to improve the sofware modularization. Testing of aspect-oriented programs is a new challenge related to this approach. Two aspects and classes test order strategies to support integration testing of aspect-oriented programs are proposed in this thesis. The objective of these strategies is to reduce the cost of testing activities through the minimization of the number of implemented stubs during integration test. An aspectual dependency model and a diagram which describes dependencies among classes and aspects called AORD (Aspect and Object Relation Diagram) used by the ordering strategies are also proposed. The aspectual dependency model and the AORD were defined considering the syntax constructions and the semantics of AspectJ. As the proposed estrategies should be applied in design phase of software development, a process to map a desing model using UML and MATA notations into a AORD is proposed in order to support the ordering strategies. The mapping process is composed by rules that show how to map both aspect and object-oriented dependencies. A characterization exploratory study using three systems implemented with AspectJ was conducted to validate the ordering strategies, the aspectual dependency model and the AORD. Interesting samples of stubs implementations were collected during the study conduction. The stubs were analyzed and classified. Based on these analysis and classification a catalog of stubs and drivers is presented

Návrh nástroje pro automatizované integrační testování / Design of Automated Integration Testing Tool

Odrobinová, Lucia January 2021 (has links)
The diploma thesis focuses on the development of an automated integration testing tool for a company. The tool is employed to detect and report data changes that may have been caused by the modification of a database schema during the development of a software. This automation of recognizing data changes brings many advantages to the company. The tool has been developed using the C# programming language, which supports object-oriented programming, using the Microsoft Visual Studio Community 2019 software. Since the tool works with the Microsoft SQL Server database, Entity Framework, an object-relational mapping framework, has been used during the implementation of the tool.
