UNASSIGNED: Natural fluctuations of sex hormones during the menstrual cycle have been shown to modulate language lateralisation. Using the dichotic listening (DL) paradigm, a well-established measurement of language lateralisation, several studies revealed that the left hemispheric language dominance was stronger when levels of @entity53 were high. A recent study (Hjelmervik et al., 2012) showed, however, that high levels of follicular @entity53 increased lateralisation only in a condition that required @entity1 to cognitively control (top-down) the stimulus-driven (bottom-up) response. This finding suggested that sex hormones modulate lateralisation only if cognitive control demands are high. The present study investigated language lateralisation in 73 normally cycling @entity1 under three attention conditions that differed in cognitive control demands. Saliva @entity53 and @entity1420 levels were determined by luminescence immunoassays. @entity1 were allocated to a high or low @entity53 group. The results showed a reduced language lateralisation when @entity53 and @entity1420 levels were high. The effect was independent of the attention condition indicating that @entity53 marginally affected cognitive control. The findings might suggest that high levels of @entity53 especially reduce the stimulus-driven (bottom-up) aspect of lateralisation rather than top-down cognitive control.
