Task 3: A psychologist was interested in the effects of television programmes on domestic life. She hypothesized that through learning by watching', certain programmes might actually encourage people to behave like the characters within them. This in turn could affect the viewer's own relationships (depending on whether the programme depicted harmonious or dysfunctional relationships). She took episodes of three popular TV shows, and showed them to 54 couples after which the couples were left alone in the room for an hour. The experimenter measured the number of times the couple argued. Each couple viewed all three of the TV pro- grammes at different points in time (a week apart) and the order in which the pro- grammes were viewed was counterbalanced over couples. The TV programmes selected were Eastenders (which typically portrays the lives of extremely miserable. argumentative, London folk who like nothing more than to beat each other up, lie to each other, sleep with each other's wives and generally show no evidence of any con- sideration to their fellow humans!), Friends (which portrays a group of unrealistically considerate and nice people who love each other oh so very much-but for some rea- son I love it anyway!), and a National Geographic programme about whales (this was supposed to act as a control). The data are in the file Eastenders.sav; access them and conduct Friedman's ANOVA on the data.
