1) An analysis of complex behavior and sequences of behavior into component responses.

2) Breaking down a complex skill, job or behavioral chain into its component behaviors, subskills, or subtasks. Each component is stated in its order of occurrence and should set the occasion for the occurrence of the next behavior. Task analyses are particularly useful in planning specific stimulus control and chaining procedures. Two types of task analyses are rational and empirical. The rational is derived from studying the subject matter and specifying the process or procedure that is presumed to be involved in doing the task. The empirical task analysis is based on systematically observing performers in action.
