Task 4: In the previous chapter we came across the beer-goggles effect, a severe perceptual distortion after imbibing alcohol that makes previously unattractive people suddenly become the hottest thing since Spicy Gonzalez’s extra-hot Tabasco-marinated chillies. One minute you’re standing in a zoo admiring the orang-utans, and 2 pints later you’re wondering why someone would put the adorable Zoë Field in a cage.

Imagine we followed up the fabricated example from the previous chapter to look at whether the beer-goggles effect is made worse by the fact that it usually occurs in clubs that have dim lighting. 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). This is our first independent variable. 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. As such, 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. To recap, all participants took part in all levels of the alcohol consumption variable, and selected mates in both brightly and dimly lit clubs. The data are in the file BeerGogglesLighting.dat. Analyse them with a two-way repeatedmeasures ANOVA.
