Answer:
behaviors, mental processes
Explanation:
Behaviours observable and easy to measure, while mental processes are not so observable or easy to measure.
Human behaviours can be measured by three fundamental properties which include repeatability, temporal extent, and temporal locus. The ability to measure human behaviour is important as it helps to identify the function maintaining a problem behavior and to evaluate the success of a positive behavior support plan. On the contrary, mental processes such as perception, memory, thinking are not easily observable or measurable.
