Marcadores discursivos en hablantes sanos y afásicos: El caso especial de y

this study compares the use of discourse markers in 20 speakers with ers no cerebral damage, 25 patients with left hemisphere damage and 10 patients with right hemisphere damage. the analysis of variance (anova) shows that there is a significant dif difference between groups concerning the total use of discourse erence markers, but no significant dif difference in their relative ference use. the study also found a prevalence of y (？and？), the frequency of which doubles that of other discourse markers. we suggest that y has the features of a default marker in all populations. finally , we propose that discourse markers, in spite of their reduced phonetic, and semantic weight, are so important in the or organization of discourse that its ganization use is preserved in aphasia.
