Diferença de complexidade de processamento entre estímulos: testagem da hipótese de que pressuposições são implicaturas de quantidade escalares

Abstract

According to Romoli (2015), presuppositions triggered by soft triggers are mandatory scalar quantity implicatures. Bill, Romoli and Schwarz (2108) report experiments with implicatural/presuppositional stimuli whose compared results, according to the authors, support this hypothesis. One of the results, however, constitutes evidence contrary to the hypothesis. This article demonstrates that the lack of parallelism identified between the results of the two experiments carried out cannot be considered evidence contrary to the assumed hypothesis, because the linguistic stimuli compared show up a difference in the number of negation operations in their processing, an intervening factor that biases the results. The result of an experiment similar to that of the authors is presented, with stimuli in Portuguese, which correct the distortion found.
