For concentrations, see Table II. PERCEIVED INTENSITY AND PLEASANTNESS RATING The correlations between perceived intensity and pleasantness rating were calculated for each concentration level of each of the four test substances, and using the two-tailed Pearson correlation test on the paired mean pleasantness and intensity ratings of each individual respondent. The findings are presented in Table VII. They show clearly different patterns for the four test substances, and also for male and female respondents. With substance II, correlations are high and negative, especially at high concentration levels, both for male and female respondents. With androstenol and substance III, correlations were also negative at all concentrations, but significant only for female respondents and only at the two highest concentration levels (and, for substance III, at the lowest concentration level). With cyclopentadecanolide there seems to be no covar- iation between perceived intensity and pleasantness. With the shirts actually worn, the correlation, although negative in most cases, is significant only in isolated instances. SEX ATTRIBUTION The findings regarding sex attribution are summarized in Tables VIII and IX. Table

Women's shirts Shirts 1-5 and 16-20, both men's and women's, had not been rated for pleasantness. VIII indicates the mean intensity rating for each cell along with its standard deviation Table IX presents the mean pleasantness ratings with their standard deviations. One- sample chi square tests for each substance, conducted separately for female and male respondents, lead to the following conclusions: Androsreno/is predominantly judged to be female at all concentration levels, both by men and by women. When calculated for combined concentration levels, the female attribution was highly significant (chi square test).
