Matrigma items require identifying logical rules (e.g., addition, rotation, progression, XOR). A 2022 study using eye-tracking found that successful 12-minute test takers exhibit a predictive gaze pattern – they scan the matrix in a zigzag order (top-left to bottom-right), fixate on the empty cell early, then return to the first row. This “anchor-first” strategy correlates with r = 0.68 with final score, independent of general processing speed. In contrast, low scorers scan randomly, re-checking completed cells.
