Final answer:
The statement is true, producing optimal pressure activates the top (green) light in the IOPI, indicating hitting the target. When using the IOPI, producing optimal pressure activates the top (green) light, indicating that the target pressure has been achieved.
Step-by-step explanation:
The IOPI (Iowa Oral Performance Instrument) is a device used to measure and improve oral and facial strength and function. It is commonly used in speech therapy and rehabilitation settings. When using the IOPI, producing optimal pressure activates the top (green) light, indicating that the target pressure has been achieved. Therefore, the statement is true that producing optimal pressure can be thought of as 'hitting the target'.
