Partículas discursivas y cognición: por tanto y la conexión argumentative

In this paperwe present experimental evidence on how the Spanish consecutive connective por tanto (en. “furthermore”) rearranges inferential routes in comprehension processes and guides the reader towards amental representation. Por tanto does not generate an argumentative relation between the discourse segments it combines. Rather, under normal circumstances, it simply makes such a relation explicit, since the segments are already argumentatively co-oriented due to their lexical content. In an eye-tracking reading experiment we compared the processing patterns of utterances in which discourse segments were connected by means of por tanto versus utterances with juxtaposed segments. A speed-up effect of por tanto on the second segment was found for the total reading time, thus confirming that, due to their procedural meaning, discourse particles add information to utterances, while, at the same time, they guide, facilitate and rearrange processing.
