Final answer:

The statement is true; the searching process involves initial visual stages followed by physical searches, and this multistage approach is reflected in how the brain processes visual information and conducts searches based on learned behavior and experience.

Step-by-step explanation:

True. The activity of searching the scene is indeed accomplished in several stages, with initial stages being visual and later stages being physical. This approach is used in tasks such as brain activity measurement using functional MRI (fMRI), where active areas of the brain show increased blood flow when engaging in specific tasks, such as recognizing a face. This process involves multiple brain functions, including visual sensory areas, integrating areas, and motor areas. For example, when searching for an object like a yellow key fob, the initial visual search would be followed by a physical search in likely locations, guided by top-down processes that are under your control and based on experience.

Moreover, sensory processing in the cerebral cortex follows a pathway from primary sensory areas to association areas and then to multimodal integration areas. This pathway is essential in processing visual information where complex shapes and depth information are discerned. In the context of recognizing faces, the primary visual cortex plays a critical role in identifying basic shapes and features that are built into a recognizable image of a face, which might trigger the recognition and button-pressing behavior as mentioned in the example experiment.
