Perceived objects automatically potentiate afforded action. Object affordances also facilitate perception of such objects, and this occurrence is known as the affordance effect. This study examined whether object affordances facilitate the initial visual processing stage, or perceptual entry processes, using the temporal order judgment task. The onset of the graspable (right-handled) coffee cup was perceived earlier than that of the less graspable (left-handled) cup for right-handed participants. The affordance effect was eliminated when the coffee cups were inverted, which presumably conveyed less affordance information. These results suggest that objects preattentively potentiate the perceptual entry processes in response to their affordances.
被感知的物体自动增强可提供的动作。物体的可供性也有助于对这类物体的感知，这种现象被称为可供性效应。本研究使用时间顺序判断任务，考察物体可供性是否促进初始视觉处理阶段或知觉进入过程。对于右利手参与者，可抓握（右手柄）咖啡杯的出现比较难抓握（左手柄）杯子的出现被感知得更早。当咖啡杯倒置时，可供性效应消失，这大概是因为传达的可供性信息较少。这些结果表明，物体在注意前阶段会根据其可供性增强知觉进入过程。
