Abstract
The aim of this study was to examine the differences in semantic and phonemic fluency tests in healthy adult participants in relation to sex and 2:4 digit ratio which was an idicator of prenatal testosterone levels, and to establish the number of words generated for five letters of Croatian alphabet (K, P, S, F and A). The data was collected on 199 participants (72 female and 47 male). For assesment of phonemic fluency letters F, A, S, K and P were used, and in the case of semantic fluency the task was to name as many animals as possible. Time for every task was limitted to 60 s. Also, the lenghts of 2nd and 4th digits on the right hand were measured. T-test showed that females have higher 2:4th digit ratio than males. ANOVA showed a significant main effect of sex on the fonemic fluency task, with females generating more words than males, while on the semantic fluency task there were no significant main effects. Neither gender or digit ratio related differences on the semantic fluency task where significant. The comparison of frequencies for the five letters used revealed a significant differences among all the letters, except S and P. The highest frequences were found for the letters K, P and S, as expected.
