Is vocal attractiveness a cue of young adult women’s susceptibility to infectious illnesses?

Although many researchers have assumed that vocal attractiveness functions as a health cue, direct tests of this assumption have been rare. Consequently, we will test possible correlations between women’s vocal attractiveness and susceptibility to infectious illnesses. We will test correlations between women’s vocal attractiveness and both a range of self-report measures of susceptibility to infectious illnesses and a commonly used salivary biomarker of immune response (secretary immunoglobulin A, measured from saliva).
