Answer the questions stated above in bold-italics. State your conclusion using the 3-sentence APA format discussed in class II. Placing children in time-out can be an effective form of punishment. Research suggests that this same technique can also be effective for adults (Chelonis, Bastilla, Brown, & Gardner, 2007). Mrs. Fran wonders if these results will generalize with a sample of STA students and if time-outs of differing lengths will influence results. She recruits nine students and shows each a series of colored shapes. Students are asked to classify each shape into one of two categories. Each correct response is rewarded with a dollar (!!) and each incorrect response is punished by a time-out period of five or ten seconds. (During the time-out no stimuli are presented and the student is unable to earn any money O.) The dependent variable is the accuracy with which students classify the shapes. At a=.05, do the data provided indicate a difference in accuracy for students when given a five second time-out as compared to a ten-second time-out? If so, in what way in accuracy influenced?
