Relational Processing
These tasks measure how quickly you can process and verify a relation between two things, such as one shape containing another or one letter coming before another. This ability may explain performance on speeded tests that involve reasoning, representing a broad kind of "reasoning speed".
Each version is inspired by Baddeley's (1968) grammatical reasoning test and presents the relation in a different format. Its original purpose was to assess cognitive impairment caused by sleep deprivation, drug use, and other stressors. It can serve as a tool for efficiently tracking your current cognitive performance.
Retake each version until your scores plateau, since your best score is the most important one and the best reflection of your ability.
