Open Matrices Item Bank
Determine your reasoning ability
Figural matrices are among the best single measures of general reasoning ability. Each item is a grid of figures that follow rules along the rows, with the last figure missing; to solve it, you have to discover the rules and apply them.
The Open Matrices Item Bank contains 220 such items. Instead of choosing from a few options, you build the missing figure from its parts, so the answer cannot be found by ruling out options. Put simply, it measures how well you find abstract patterns and reason with them.
On the following pages, you can determine your reasoning ability by solving 220 matrix items. There is no time limit: the whole test takes several hours, and your answers are saved after every item, so you can spread it over several sessions.
The results will be provided immediately after you have completed the final item. Please note that the results you receive can only be reliable to the extent that you work attentively and without help.
This test is part of the validation study for the Quantitative Socionics Inventory. In case of any question, please write an e-mail (contact@quantitativesocionics.org) to the research team.
About this test
- Procedure
- Each item is a 3 × 3 grid of figures following rules along the rows, with the last figure missing. You build the missing figure by selecting exactly the right parts from 20 figure elements. Two practice items with feedback, then all 220 items in the ten sets of the original study, without a time limit.
- Main outcome
- Ability estimate (θ) from the published item parameters (2PL); items solved and accuracy by number of rules are also reported.
- Also reported
- Items solved · Accuracy · Standard error of θ · Accuracy, items with 1 rule · Accuracy, items with 2 rules · Accuracy, items with 3 rules · Accuracy, items with 4 rules · Accuracy, items with 5 rules · Median time on solved items (ms) · Total time on the items (ms)
- Input
- Mouse or touch screen.
- Study
- Your answers are stored anonymously under the same private profile as the Quantitative Socionics Inventory, so that results can be compared across participants. You can pause and resume.
