In our earlier experiment, where complexity paired comparisons were run first, there was no systematic difference in the z-score range between preference and complexity (Table VII).

The correlation between perceived complexity and chemical complexity was also better for the female respondents than for the male ones, both in this study and in the previous one (Table VIII). This is due in part to the female's higher complexity ratings for the fine fragrances (type RG and PR). A particularly encouraging finding was that the relative complexity scores of the 5 stimuli which were common to both the first study and the second one were very similar in the two studies, with high rank correlations especially with the female Table VIII Rank Order Correlation Between Perceived Complexity and Chemical Complexity M F Study 1--solutions + 0.55 + 0.64* Study 2--solutions +0.38 +0.52 Study 2--creams + 0.34 + 0.16 *p 0.05
