conclusions the current study revealed that a significant difference existed in hgs among the low, medium, and high bmi groups. a positive correlation existed between hgs and weight and height, while sex was the most significant factor affecting hgs. these findings can serve as a reference to assess hgs prediction, whereby the sex effect should be considered. results the results showed that the...

Sex differences in vowel acoustics were found to be mediated by words' frequency of use and phonological neighborhood density. Larger sex differences in vowel-space expansion were found for words with high frequency of use and for words with small phonological neighborhoods, than for words than for words with low frequency of use and high neighborhood density. Results suggest that talkers' prod...

Recent studies conclude that men on average have higher intelligence than women by 3-5 IQ points. However, the ultimate evolutionary question of why men should have evolved to have higher intelligence than women remains. We suggest that men may have slightly higher intelligence than women through 4 mechanisms: (1) assortative mating of intelligent men and beautiful women, (2) assortative mating...

Voice onset time (VOT) data for the plosives /p b t d k g/ in two vowel contexts (/i a/) for 5 groups of 46 boys and girls aged 5; 8 (5 years, 8 months) to 13;2 years were investigated to examine patterns of sex differences. Results indicated that there was some evidence of females displaying longer VOT values than the males. In addition, these were found to be most marked for the data of the 1...
