Task 1: In the previous chapter we looked at an example in which participants viewed a total of nine mock adverts over three sessions. In these adverts there were three products (a brand of beer, Brain Death; a brand of wine, Dangleberry; and a brand of water, Puritan). These could be presented alongside positive, negative or neutral imagery. Over the three sessions and nine adverts, each type of product was paired with each type of imagery (read the previous chapter if you need more detail). After each advert participants rated the drinks on a scale ranging from −100 (dislike very much) through 0 (neutral) to 100 (like very much). The design had two repeated-measures independent variables: the type of drink (beer, wine or water) and the type of imagery used

(positive, negative or neutral). Imagine that we also knew each participant’s gender. Men and women might respond differently to the products (because, in keeping with stereotypes, men might mostly drink lager whereas women might drink wine). Reanalyse the data, taking gender (a between-group variable) into account. The data are in the file MixedAttitude.sav. Run a three-way mixed ANOVA on these data. ③
