Final answer:
In a stimulus fading procedure, characteristics such as size, shape, and color of a stimulus may be exaggerated to help with differentiation and response, and then gradually normalized.
Step-by-step explanation:
When using a stimulus fading procedure, the stimulus characteristic that might be exaggerated or highlighted can include size, shape, and color. These characteristics are intentionally altered to help an individual differentiate and respond to a specific stimulus more effectively.
The process often involves starting with an exaggerated version of the stimulus, such as a larger size, more distinct shape, or brighter color, and then gradually reducing these exaggerations to the normal level as the individual becomes better at recognizing and responding to the stimulus.
This technique is commonly used in educational and therapeutic settings to aid learning and behavior modification.
