Behavioral Studies Of Object Perception

The previous section described research by physiological psychologists and neuroscientists on how different neurons and different parts of the brain contribute to the process of object perception. Other cognitive scientists have studied object perception through behavioral experiments on human subjects with normally functioning visual systems. In these studies, subjects are asked to perform a task on a selected set of stimuli, for example, naming pictures of common objects. Some aspect of the stimuli (e.g., the viewpoint from which each stimulus is pictured) or the task (e.g., the duration of time that the stimulus remains on the screen) is varied, and subjects' responses are recorded. By examining the relationship between the manipulated variable and responses, we can indirectly learn something about how the brain is processing the stimuli in order to perform the task.
