Leuven Embedded Figures Test (L-EFT)
The L-EFT is a percepetual match-to-sample test and measures how fast participants can identify an embedded figure within a more complex pattern. The test manipulates several variables (such as shape symmetry and number of lines) to investigate the impact of target features on detectability.
