Top-down information fills in what"s missing from what bottom-up information: context can affect your ability to recognize objects. Top-down influences what information do simple (i. e. , the first version) feature nets and rbc use to identify words and objects. Other words in sentence, other information in picture provides context (top-down information) Context helps prime representations of related information. Recognition seems effortless and automatic unless the problem is difficult we don"t even realize the process is taking place. We can recognize objects across variability, occlusion, different viewing distances and orientations. In some cases, we can recognize objects that aren"t present in the physical stimulus.
