<p>A Test Battery (TB) is a measurement method that is designed to assess a variety of ability constructs. The extent to which TB predicts future pilot performance has important implications for both flying organizations and applicants. The primary emphasis in the existing literature has been on scores of individual ability tests, in contrast to the scores of multiple ability tests that are typically indexed by composites derived from TBs. The selection literature lacks a focus on composite scores, and seldom links to the broad cognitive abilities that predominate TBs. The objective of this study was to investigate how the different broad ability constructs of TBs influence their predictive validities for pilot performance. Six ability groups were identified as the most common ability saturations of pilot selection TBs. On the basis of 89 studies and 118 independent samples, a series of meta-analyses were conducted to determine the criterion-related validity of the six categories of TBs for several criterions of pilot performance.</p> <p>The investigation revealed there was an overall small and positive relationship between TBs and flight performance. The six categories of cognitive ability TBs appeared to be valid predictors of pilot performance, and at least five of them generalize validity across studies and settings. More specifically, three sets of predictor groups were identified according to the magnitude of validity estimates. The highest validity group included <i>Work Sample</i> TBs (<i>r</i>=.34), the second highest validity group included TBs of <i>Acquired Knowledge</i>, <i>General Ability</i>, and <i>Motor Abilities</i> (<i>r</i>=.19, .18, and .17, respectively), and the lowest validity group included TBs of <i>Perceptual Processing</i> and <i>Controlled Attention</i> (<i>r</i>=.14 and .10, respectively).</p> <p>The results also indicated that there was substantial variability in the effect of cognitive abilities on flight performance, with evidence of moderators operating in most cases. Five potential moderator variables were examined that may moderate the TBs-performance relationship in flying. The analysis for the moderator variable of <i>the number of tests in the battery </i>(small battery/large battery), <i>regularity of TB use in pilot selection</i> (commonly used/uncommonly used), and <i>criterion level of measurement</i> (continuous/ordinal/dichotomous/ contingency table) revealed significant moderating effects on the correlations between flight performance and several types of test batteries. Other moderators related to <i>year of publication</i> (1987-1999/2000-2009/2010-2017) and <i>flying organization</i> (USAF/US Navy/Another military/Civilian) did not significantly influence the correlations between TBs and flight performance. The implications of the findings for practice are discussed, and recommendations for future research directions are provided.</p>

Syfte och frågeställningar Studiens syfte är att undersöka relationen mellan ungdomsmålvakters resultat i vanligt förekommande standardtester som är avsedda att mäta fysisk kapacitet och deras prestation i matchlika aktioner. Syftet är också att undersöka om resultaten skiljer sig mellan målvakter i två olika ålderskategorier. Frågeställningar: Vad är korrelation mellan resultat i standardtester och matchlika aktioner? Skiljer sig resultaten mellan ungdomsmålvakter på U17 och U19 nivå? Metod För att svara på studiens frågeställningar skapades ett testbatteri innehållande fysiska tester designade för fotbollsmålvakter, utifrån deras rörelsemönster och aktioner (verklighetsnära tester), som jämförs med tester som används av dagens fotbollsklubbar (standardtester). Med hjälp av aktuellt forskningsläge tillsammans med information som mottagits från tränare och målvakter, utfördes 6 tester, på 15 målvakter, som registrerades med mätinstrument och höghastighetskameror. Resultatet analyserades med dubbelsidig t-test för att finna en statistisk signifikans mellan två åldersgrupper och Spearmans test för att finna en korrelation mellan standard- och verklighetsnära testerna. Resultat Resultatet från t-testet visade ingen signifikant skillnad mellan U17:s och U19:s målvakter på samtliga tester (p&gt; 0,05). Spearmans test visade ingen statistiskt signifikant korrelation mellan testerna. Slutsats Både standard- och verklighetsnära testerna har sina fördelar men är syftet att utvärdera målvaktens fysiska kapacitet i matchlika situationer genom tester, bör dessa vara utformade utifrån målvaktens agerande under match. Enligt resultaten från denna studie visar detta att man inte enbart kan använda standardtester utan dessa bör kompletteras med tester specifikt utformade för måvakter. / Aim The aim of the study is to investigate the relationship between youth goalkeepers' results in commonly used standard tests that are intended to measure physical capacity and their performance in match-like actions. The purpose is also to investigate whether the results differ between goalkeepers in two different age categories. Research questions: What is the correlation between results in standard tests and match-like actions? Do the results differ between youth goalkeepers at U17 and U19 level? Method To answer the study's questions, a test battery was created containing physical tests designed for football goalkeepers based on their movement patterns and actions (match-like actions) compared to tests used by today's football clubs (standard tests). With the help of research, together with information we received from coaches and goalkeepers, 6 tests were designed and performed, on 15 goalkeepers, which were recorded with measuring instruments and high-speed cameras. The results were analyzed with two tailed t-test to find a statistical significance between the two age groups and Spearman's test to find a correlation between the standard and realistic tests. Results The results of the t-test show no significant difference between the U17 and U19 goalkeepers on all tests (p&gt; 0.05). Spearman's test shows that there was no statistic significant correlation between the tests. Conclusions Both standard and realistic tests have their advantages, but if the purpose is to evaluate the goalkeeper's physical capacity in match-like actions through tests, should these be designed based on the goalkeeper's actions during the match. According to the results of this study, this shows that you should not just use standard tests, but these should be supplemented with tests specifically designed for goalkeepers.

Anyone desiring to qualify as an accountant or auditor is required to pass an examination as approved by the Public Accountants' and Auditors' Board to establish whether candidates have attained the required standard of academic knowledge in terms of the syllabi laid down by the Board, as well as whether they are able to apply that knowledge in practice (P AAB, 1995). However each year many students fail this very important examination. The reasons for this are not clear and the purpose of this research is to determine whether: personality; vocational interests; intelligence; matriculation Mathematics and home language (English/ Afrikaans) results, predict success in the QE, by comparing a group of successful and unsuccessful QE candidates. The logistic regression, discriminant analysis and t-test statistical procedures, indicated that: warmth (A), liveliness (F), rule-consciousness (G), social boldness (H), apprehension (0), self-reliance (Q2), perfectionism (Q3), tension (Q4), computational interest, social services interest, mechanical interest, Mental Alertness and matriculation home language, are significant factors to consider when identifying candidates likely to be successful in the QE. / Industrial and Organisational Psychology / MCOM (Industrial Psychology)

There has always been a need for objective tests that assess auditory function in infants, young children, and/or any patient whose development level precludes the use of behavioral audiometric techniques. Although the Auditory Brainstem Response (ABR) is seen as the ‘gold standard’ in the field of objective audiometry, it presents with its own set of limitations. The Auditory Steady State Response (ASSR) has gained considerable attention and is seen as a promising addition to the AEP ‘family’ to address some of the limitations of the ABR. The ASSR promises to estimate all categories of hearing loss (mild to profound) in a frequency specific manner. It also indicates to the possibility to validate hearing aid fittings by determining functional gain of hearing aids by determining unaided and aided ASSR thresholds. An exploratory research design was selected in order to compare unaided thresholds, obtained through the use of three different procedures – ABR, ASSR and behavioral thresholds. Aided thresholds were also obtained and compared with two procedures – the aided ASSR (measured and predicted) and aided behavioral threshold. The results indicated that both the ABR (tone burst and click) and ASSR provided a reasonable estimation of the subsequently obtained behavioral audiograms. The ASSR, however, approximated the behavioral thresholds closer than the ABR and were furthermore able to quantify hearing thresholds accurately for subjects with severe and profound hearing losses. The result indicated further that the ASSR can be instrumental in the validation process of hearing aid fittings in infants. These results demonstrated however, that the ASSR measured thresholds underestimate the aided behavioral thresholds and the aided ASSR predicted thresholds overestimate the aided behavioral thresholds. The research concluded that the ASSR is useful in estimating frequency-specific behavioral thresholds accurately in infants and validating hearing aid fittings. Until evidence is sufficient to recommend the ASSR as primary electrophysiological measure of hearing in infants, the ASSR should be used in conjunction with the ABR – following a test battery approach in the diagnostic process of hearing loss in infants. The ASSR further shows great promise in validating hearing aid fittings, but this specific application of the ASSR needs further research evidence on large groups to validate the procedure. / Dissertation (Master of Communication Pathology)--University of Pretoria, 2007. / Speech-Language Pathology and Audiology / unrestricted

Title: Occurrence of coordination disorders in children with hearing impairment Objectives: The aim of this master thesis was to verify the hypothesis that children with hearing impairment have higher incidence of sensorimotor issues byassessing their motor skills, physical fitness and somatognostic functions. A partial goal was to assess the correlation between the methods used. Methods: The examination group consisted of 73 children (27 girls and 46 boys) with hearing impairment aged 7 to 16 years (mean age 11.9 ± 2.8 years). The mean weight of the children was 47.7 ± 17.4 kg, the mean height was 153 ± 17.5 cm and the average BMI value was 19.7 ± 4.1. Following methods for testing of children with hearing impairment were utilized: the Movemet Assessment Battery for Children - Second Edition (MABC-2) and Unifittest 6-60. Results were evaluated according to Czech standards. All children were also tested for their somatognostic functions according to Kolář. Furthermore, anamnestic data were obtained from parents of 54 children using a non-standardized questionnaire. In the case of 20 children, the assessment was repeated after 3 years. Statistica and Microsoft Excel 2016 were used for data processing. Results: The hypothesis was confirmed, i.e. children with hearing impairment have higher incidence...

Vehicle accidents by means of Public transport annually leads to a large number of passenger deaths and life long disablement. AsDu Toit, Martina Petronella a result, there is a need for preventative measures by identifying the psychomotor abilities of bus drivers during the recruitment and selection process of employment. The study was conducted among 398 bus drivers employed by a large bus company. The Vienna Test Battery was administered. It was found that distance estimation, ability to recognize forms and figures, concentration ability, eye-hand feet coordination and two-hand coordination predicted the effectiveness of bus drivers successfully. It is suggested that further research should focus on client services, attitude of bus drivers and learning potential, as factors that influence the effectiveness of bus drivers. / Industrial psychology / M.A. (Industrial Psychology)
