Cover Story: Figural-matrix tests are frequently used to measure fluid intelligence. The HeiQ (pronounced high-q), an operation-oriented figural-matrix test developed to overcome the limitations of previous tests, focuses on active construction instead of the possibility of excluding distractors based on superficial features. To accommodate for a wide variety of study designs, the goal of this study was to develop three short forms of the original HeiQ: two parallel short forms (the HeiQ-S A and HeiQ-S B) taking 25 minutes and an extra-short form (HeiQ-XS) taking only 10 minutes. All the tests showed good internal consistency and good construct validity and were able to predict academic performance (high school grades). For research purposes, all versions are free to use and available in multiple languages. View this paper
