People with high values in this test are able to think logically and formally abstract. They can process given verbal information and consequently draw conclusions from it.


Z (Z-Score): Standard score in value range 70-130 (M=100, SD=10); PR (percentile rank): Share in reference group with a score that is at most as high.


After an introductory instruction and a trial task, SYLLOG is completed in a time-limited, multiple choice format (single selection from 5 alternatives). One item per page is shown, which can be solved by means of logical conclusions. It is possible to skip items, and to scroll forwards and backwards.

The test is implemented in liquid format: the items are drawn from a pool and arranged according to increasing difficulty, whereby test difficulty and subject areas are kept constant for all participants.

Theoretical background

The concept of "truth-preserving thought“ in the form of syllogisms is rooted in a long cultural-historical tradition dating back to Aristotle. Syllogisms are pairs of premises (conditions) from which a logically correct conclusion can clearly be drawn.

SYLLOG captures a partial area of verbal processing capacity by capturing the ability to deductively derive the correct result through formal and logical conclusions from predefined statements. For this purpose, the presented verbal information must be represented mentally and linked together in an abstract form.  

The ability to make logical conclusions ascertained via SYLLOG is always relevant if complex verbal information has to be assessed correctly and decisions made based on this.
