Thirty-ve years ago the journal Behavior Research and Therapy 4 reported a study that compared two mild shock therapies for stuttering. There were 18 subjects, all of them stutterers. Each subject was given a total of three treatment sessions, with the order randomized separately for each subject. One treatment administered a mild shock during each moment of stuttering, another gave the shock after each stuttered word, and the third treatment was a control, with no shock. The response was a score that measured a subject's adaptation. ( q1: give response ) ( q2: The name of the two factors ) ( q3: For each factor, tell whether it is observational or experimental and the number of levels it has) (q4: Tell whether the study is a complete block design)
