Computer-based tests: the impact of test design and problem of equivalency

Pocitacove formy diagnostických metod jsou casto publikovany s psychometrickými charakteristikami pochazejicimi z tradicnich forem metod a bez dokladů o ekvivalenci s těmito formami. Navic casto existuje vice pocitacových forem tehož testu, ktere se lisi svým designem. Studie I se zaměřuje na vliv designu na výsledky testu. Bylo zjistěno, že změna v barevnem schematu Bourdonova pozornostniho testu (světle podněty na tmavem pozadi vs. tmave podněty na světlem pozadi) ovlivňuje výkon probandů. Studie II se zabýva ekvivalenci pocitacove formy Testu koncentrace pozornosti, který je casto použivan v psychologicke praxi v ramci Ceske republiky. Pocitacova a tradicni forma vykazuji znamky neekvivalentnosti.

Innovative testing of spatial ability: interactive responding and the use of complex stimuli material

Despite initial expectations, which have emerged with the advancement of computer technology over the last decade of the twentieth century, scientific literature does not contain many relevant references regarding the development and use of innovative items in psychological testing. Our study presents and evaluates two novel item types. One item type is derived from a standard schematic test item used for the assessment of the spatial perception aspect of spatial ability, enhanced by an interactive response module. The performance on this item type is correlated with the performance on its paper and pencil counterpart. The other innovative item type used complex stimuli in the form of a short video of a ride through a city presented in an on-route perspective, which is intended to measure navigation skills and the ability to keep oneself oriented in space. In this case, the scores were related to the capacity of visuo-spatial working memory and also to the overall score in the paper/pencil test of spatial ability. The second relationship was moderated by gender.
