| summary | Visual backward masking is an often used paradigm in the visual sciences and psychology. However, the mechanisms underlying masking are still poorly understood. In this talk, I will discuss data suggesting that often made assumptions about visual masking do not always hold. First, I will discuss the fact that delaying the mask with respect to the target does not always lead to weaker masking. Second, I will describe experiments showing that increasing the luminance of the mask does not always result in stronger masking. Finally, I will present data showing clear interactions between a simultaneous and a backward mask. The discussed findings suggest that masking should only be used when its underlying assumptions are tested experimentally. |
