通过侧面的视觉掩模可以促进视觉目标的检测。当观察者想象先前感知到的面具时，检测阈值也得到了类似的增强。图像诱导的促进检测长达5分钟后，由目标眼睛的面具观察。这些结果表明，存在一个低水平（单眼）的记忆，存储的感觉痕迹几分钟，并使更高的过程重新激活早期的代表。这种记忆，以其象似性，可能有助于心理意象和知觉之间的界面。
Detection of a visual target can be facilitated by flanking visual masks. A similar enhancement in detection thresholds was obtained when observers imagined the previously perceived masks. Imagery-induced facilitation was detected for as long as 5 minutes after observation of the masks by the targeted eye. These results indicated the existence of a low-level (monocular) memory that stores the sensory trace for several minutes and enables reactivation of early representations by higher processes. This memory, with its iconic nature, may subserve the interface between mental images and percepts.
