SECTION A Read the following research report carefully, and then answer all the questions. The allocation of marks for each question is indicated in the margin. their environment. For instance, are we more likely to notice psychology books in the library if we have signed up for a psychology class? Are we more likely to notice food in a shop window, rather than clothes or cosmetics, if we are feeling very hungry? The researchers set up an experiment in which they allocated student volunteers to one of two groups on a random basis. Participants in one group were asked not to eat for 12 hours before the study. A second group were given a meal just before the experimental task. It was assumed that these people were not hungry - that they were ±satiated&. Participants in both groups were asked to memorise a long list of words, half of which were related to food ( e.g. kitchen, taste, fry). Both groups were exposed to the word list by presenting each word on a computer screen, preceded by a clear tone, for exactly five seconds. Participants were asked to complete a small jigsaw puzzle for five minutes, then they were tested for recall of the words in the list. A record was made of the number of food-related and non food-related words correctly recalled. The results for food-related words are shown in Table I below. Table I - Numbers of food-related words correctly recalled by hungry and satiated participants 3.5 6 18 15 16.5 14 20 18 12 12 16.5 14 1 4 12 12 8 9 5.5 8 12 12 12 12 3.5 6 12 12 8 9 19 16 8 9 5.5 8 2 5 15 13 Rank of column (c) score Food words recalled by satiated participants Rank of column (a) score Food words recalled by hungry participants d c b a 5 10 ² 2 ² M01/350/H(2) 221-062

The difference between numbers of food-related words recalled by the two groups of participants was found to be significant ( p < 0.01). The researchers also looked at the difference between non-food words recalled by hungry and satiated participants but this difference was found not to be significant so the null hypothesis was retained in this case. 15
