The International Cognitive Ability Resource (ICAR)
The International Cognitive Ability Resource (ICAR) project resulted in a large collection of assessment instruments for cognitive abilities that can be used in a wide variety of applications. Several hundred research groups around the world use the assessment instruments developed through this initiative. In addition to the core team, other groups have also contributed—and continue to contribute—to their ongoing revision and further development. ICAR makes use of automatic item generation techniques, which produce test items with predictable psychometric properties.
Please note that ICAR is intended for academic use exclusively.
Funding Acknowledgement
The original ICAR project was jointly funded by the National Science Foundation (NSF) in the US, the Deutsche Forschungsgemeinschaft (DFG) in Germany, and the Economic and Social Research Council (ESRC) in the UK as part of the Open Research Area Plus for the Social Sciences (NSF: SMA-1419324; DFG: DO 1789/1-1, ESRC: ES/L016591/1). We acknowledge funding for the continued improvement of the ICAR by The Eric and Wendy Schmidt Fund for Strategic Innovation.
Available Item Types: ICAR 60
The ICAR 60 is the most popular test originally developed by Condon and Revelle. If you are looking for a brief measure, the 12 item "Sample Test" has proven to be surprisingly robust. The ICAR 60 includes items for
- Three-Dimensional Rotation
- Letter and Number Series
- Matrix Reasoning
- Verbal Reasoning
The subfolder ICAR60_and_related_tests contains the ICAR 60 and various translations, as well as a variant intended for children. Many translations have been kindly contributed by the community.
Available Item Types: Further ICAR-Item Types
- Figural Analogies Test (FAT)
- Number Series
- Perceptual Maze
- Propositional Reasoning
Additional Item Type Contributed to ICAR
- Face Detection (contributed by R. Verhallen)
- Figural Analogies (contributed by D. Blum) along with documentation on the IMak generator
- Melodic Discrimination (contributed by Harrison and Müllensiefen)
- Children's ICAR (contributed by Dutry et al.)
