Task 4: The ‘roving eye’ effect is the propensity of people in relationships to ‘eye up’ members of the opposite sex. I took 20 men and fitted them with incredibly sophisticated glasses that could track their eye movements and record both the movement and the object being observed (this is the point at which it should be apparent that I’m making it up as I go along). Over four different nights I plied these poor souls with 1, 2, 3 or 4 pints of strong lager in a nightclub. Each night I measured how many different women they eyed up (a woman was categorized as having been eyed up if the man’s eye moved from her head to her toe and back up again). The data are in the file RovingEye.sav. Analyse them with a one-way ANOVA. ②

Task 5: In the previous chapter we came across the beer-goggles effect, a severe perceptual distortion occurring after imbibing several pints of alcohol that makes previously unattractive people suddenly become the hottest thing since Spicy Gonzalez’s extra-hot Tabasco-marinated chillies. In short, one minute you’re standing in a zoo admiring the orang-utans, and the next you’re wondering why someone would put the adorable Zoë Field in a cage. Anyway, in that chapter, we demonstrated that the beer-goggles effect was stronger for men than for women, and took effect only after 2 pints. Imagine we followed this finding up. We took a sample of 26 men

(because the effect is stronger in men) and gave them various doses of Alcohol over four different weeks (0 pints, 2 pints, 4 pints and 6 pints of lager). Each week (and, therefore, in each state of drunkenness) participants were asked to select a mate in a normal club (that had dim lighting) and then select a second mate in a specially designed club that had bright lighting. The second independent variable was whether the club had dim or bright lighting. The outcome measure was the attractiveness of each mate as assessed by a panel of independent judges. The data are in the file BeerGogglesLighting.sav. Analyse them with a two-way repeated-measures ANOVA. ②
