Assessing the development of automaticity in second language word recognition

Abstract

AbstractThis study investigated the development of automaticity in second language word recognition. In an earlier study (Segalowitz & Segalowitz, 1993) we demonstrated that a reduction in the coefficient of variation of lexical decision reaction time (CVRT) - the standard deviation of reaction time divided by mean reaction time (RT) - reflects a restructuring of underlying cognitive processing mechanisms in the direction of increased automaticity and not a simple speed-up of those mechanisms. In the current study, English speakers studying French performed multiple lexical decision tasks. Differences in CVRTwere compared cross-sectionally and longitudinally. As in the earlier study, crosssectional analyses showed that CVRTcorrelated positively with RT for initially fast, but not initially slow, responders. CVRTalso correlated positively with RT in longitudinal analyses. These results confirm that, with extended learning experience, the cognitive components underlying word recognition are restructured (automatized) and not simply speeded-up.
