Study title

The data is categorised by item types. Each folder contains datasets for one item type, including the item-level data, the participants information, and the item files. There are 8 folders in total, contributing data for 2d rotation test, 3d rotation test, face detection test, matrices reasoning test, perceptual maze test, two number series tests, and linear syllogism test.After more than a century of active research on cognitive abilities, there now exist dozens of assessment tools of tremendous variety. Many of these are no longer widely used on account of being outdated or poorly maintained. Most of the remainder - those tests which are actively used and well maintained - can generally be organized into two broad types: (i) proprietary measures owned and administered by profitable commercial entities or (ii) idiosyncratic measures which are usually developed and used by isolated research groups for narrow purposes. This circumstance is problematic for the international community of cognitive ability researchers because it inhibits the generalization of findings across sub-fields and, more generally, slows the pace at which knowledge can advance. The tangible consequences of this circumstance on the societal level are manifested through limited utility of cognitive ability assessment in clinical settings (as used for diagnoses of cognitive impairment) and selection contexts (as used for personnel recruitment or academic admissions). These consequences will be addressed by the development of the International Cognitive Ability Resource (ICAR), a public-domain and open-source tool which will incorporate modern item generation and adaptive testing techniques. At its essence, ICAR is a framework for international collaboration. This framework will facilitate the development of a large and dynamic bank of cognitive ability measures for use in a wide variety of applications. By encouraging the use, revision, and ongoing development of these measures among qualified...
