Final answer:
The two types of behavior important to behavior analysis are operant and respondent behaviors. Operant behaviors are learned and influenced by consequences, while respondent behaviors are innate, reflexive responses to stimuli.
Step-by-step explanation:
The two functionally distinct types of behavior important to behavior analysis are d) Operant and respondent behaviors. Operant behaviors are those that are influenced by the consequences that follow them. For example, a dog will learn to sit if it is given a treat every time it performs the action. This type of learning is a part of conditioned behaviors, where a response is modified by reinforcement or punishment. Respondent behaviors, on the other hand, are reflexive and occur as an automatic response to a stimulus. A classic example is salivating when smelling food. This type of behavior is typically innate or instinctual and is largely independent of environmental influences.
