Figural matrices tasks are one of the most prominent item formats used in intelligence tests, and their relevance for the assessment of cognitive abilities is unquestionable. However, despite endeavors of the open science movement to make scientific research accessible on all levels, there is a lack of royalty-free figural matrices tests. The Open…

Research on scientific reasoning plays an essential role at the intersection of cognitive development and science education. As only few paper-pencil-tests exist to assess scientific reasoning abilities of elementary school children, the goal of the current study was the development of a new reliable and valid instrument. We focused on the…

This study investigated the development and validation of a 32-item scale that measures "Internet-Savviness" (IS). Relationships between this multidimensional construct and other primary variables of interest including age, gender, Internet access, Internet location, and Internet activities were explored. The sample population consisted of 241…

Social intelligence is a construct that has shown promising practical applications, but its use in research and applied settings has been limited by definitional problems and the complexity of most existing measures of social intelligence. The goal of the present study was to adapt the Italian version [Gini & Iotti (2004) "La Tromso…

The purpose of this study was to construct and validate a test of critical thinking ability. A preliminary form was checked for face validity by a panel of experts in reading. Item analysis of this form resulted in a final form consisting of four parts with three subscales each. This form, and tests of intelligence and general reading ability,…

The purposes of the study were to investigate the effects of the combination of a trained teacher and a planned program on the problem solving abilities of mentally handicapped children, to develop measures of verbal problem solving (IDES) and arithmetic understanding (PUT), and to analyze the interrelationships among primary mental abilities and…

This collection of papers, concerned with the nature and theory of intelligence, forms part of a project to integrate test and factor theory with the empirical, functional relationships involving standard intelligence tests. The project will render more objective the use of factor analysis in personnel research. A definition of intelligence…

A series of studies and analyses to develop brief, reliable measures of intelligence and achievement motivation that would be feasible for use in a cross-sectional sample is summarized. One measure of intelligence meets these criteria. It is a 13-item test of sentence completion skill, which correlates effectively with other measures of…
