Comparison of wild-type CS flies' performance to five white mutant alleles, brown (bw1), and scarlet (st1) mutant flies in a thermosensitivity test and the 3-min memory test with two reinforcing temperatures (37 and 41°C). In the thermosensitivity tests comparing wild-type CS flies with the white mutations, Kruskal-Wallis tests for each probe temperature are: 37°C, H = 38.87, P = 0.000; 41°C, H = 7.43, P = 0.19. Comparing wild-type CS flies with bw1 and st1 flies in the thermosensitivity tests found no significant differences with temperatures tested (37°C, H = 4.47, P = 0.10; 41°C, H = 4.50, P = 0.22). In tests for place memory using two different reinforcing temperatures, four of the five tested white alleles showed decreased performance with both temperatures (37°C, H = 25.60, P = 0.001; 41°C, H = 14.51, P = 0.013). The st1 but not bw1 mutation significantly reduced place memory using the 37°C reinforcer (H = 21.73, P = 0.000). Significance levels are shown for each genotype compared to wild-type CS flies performance tested in parallel. See legend of Figure 2 for levels of significance denoted by the asterisks.
