AB Relational Processing is a computerized version of Baddeley's (1968) grammatical reasoning test. Each item shows a sentence about two letters and an arrangement, AB or BA. Decide whether the sentence correctly describes the left-to-right order.

Precedes means comes before and follows means comes after. Watch for passive wording and for "not": "A is followed by B" means A comes before B, and "A is not followed by B" reverses that claim. There is no time limit, but your score is correct minus incorrect answers per minute, so work accurately and efficiently.

Retake this task until your scores plateau, since your best score is the most important one and the best reflection of your ability.
