Question

Quizplus · Accepted Answer

The target stimulus that is being looked for in a scene is referred to as a signal. It could be a specific object, person or event that the observer is trying to detect. Choosing A, movement-filter theory, is incorrect as it refers to how our visual system filters out irrelevant information and focuses on motion which is not related to the specific item being looked for. Choice C, False Alarm, is also incorrect as it refers to the detection of a signal that is not actually present. Dishabituation (D) is a phenomenon where a person notices a previously habituated stimulus once again, which is not relevant to searching for a specific item in a scene.
