Phonetically Cued Word-fluency, Gender Differences and Aging: a Reappraisal

Five-hundred and three normal subjects were given a phonetically cued word-fluency task in order to investigate the controversial issue of the influence of gender and aging on this task. Subjects were requested to say in one minute all the words that occurred to them, beginning with a given letter (F, P and L). Besides the expected significance of education, we observed a female advantage, but not a significant decline in the performance with aging. However, the slope of the line expressing word fluency as a function of age was different between females and males, indicating a greater sensitivity to aging for males. We provide inner and outer tolerance limits for this test in the normal population and give a formula useful for adjusting the raw scores on the basis of gender and education. The results are discussed with reference to previous findings and some hypotheses about the origins of the female advantage in PWF.
