Resumen
This paper reports the results of two ERP studies that have been conducted with the following aims: (i) the aim of assessing the evidence for non-incremental models of negation processing (Kaup et al. (2006), (2007)), particularly in the version based on the Two Step Simulation Hypothesis (Lüdtke et al. (2008)), and (ii) the aim of assessing possible differences in the processing of negation between normally-developed and dyslexic adults. The results that emerge from the behavioral data and from the statistical elaboration of the collected EEG data concerning normallydeveloped adults provide substantial confirmation for the existence of a first stage of processing in which negation is still not integrated (thus for a non-incremental model of negation processing), though they also suggest that the mental representations created at the different stages of processing are dynamically compared in the course of the whole process rather than being sequentially produced and suppressed. Though no wellknown ERP effect emerges with adult dyslexics, the EEG data strongly suggest that negation processing by adult dyslexics follow a completely independent route with respect to normally-developed adults, which dispenses with sentence-picture priming effects but finally results in a functionally less effective processing strategy, as also confirmed by the behavioral data (i.e. higher reaction times and lower accuracy rates)
