被掩盖的物体图片被短暂地闪过，只有13.5%的物体能被命名。对不明物体的强制选择精度是偶然的。当图片再次显示时，大约15分钟和20次干预试验后，没有任何可能重复的迹象，命名准确率提高到34.5%。启动完全是视觉的，而不是语义或言语，因为没有相同的名称，不同形状的图像启动。这是第一次演示的促进视觉识别启动时，未识别的图片时，受试者不能预期，如果当，或在以前未识别的图片将再次显示。物体位置的变化减少了但没有消除启动，允许推测阈下视觉启动的位点处于腹侧皮层通路中的中间阶段，用于形状识别。
Masked pictures of objects were flashed so briefly that only 13.5% of them could be named. Forced-choice accuracy for the unidentified objects was at chance. When the pictures were shown again, about 15 min and 20 intervening trials later without any indication of possible repetitions, naming accuracy increased to 34.5%. The priming was completely visual, rather than semantic or verbal, as there was no priming of same-name, different-shape images. This is the first demonstration of facilitatory visual recognition priming by unidentified pictures when the subject could not anticipate if when, or where the previously unidentified picture was to be shown again. A change in the position of the object reduced but did not eliminate the priming, allowing a speculation that the locus of subliminal visual priming is at an intermediate stage in the ventral cortical pathway for shape recognition.
