UN EJEMPLO DEL ESPAÑOL Grammatical Gender and Number Agreement in Spanish: An ERP Comparison. Horacio Barber, Manuel Carreiras. Journal of Cognitive Neuroscience January 2005, Vol. 17, No. 1: 137– /18/11 6 SPAN Harry Howard - Tulane University

LOS EXPERIMENTOS The first experiment compared the effect of agreement in article–noun word pairs (e.g., el piano ) and in noun–adjective word pairs (e.g., faro alto ), The second experiment compared the effect of agreement between the same words at the beginning of sentences (e.g., El piano estaba viejo y desafinado ), or in the middle of sentences (e.g., El faro es alto y luminoso ). 04/18/11 7 SPAN Harry Howard - Tulane University

¿POR QUÉ? This way, comparing the results of both experiments, we could also trace the impact of the sentence context and reading expectations in the ERP components associated to syntactic processing, as well as the influence of the amount of syntactic information available during the course of sentence reading. 04/18/11 8 SPAN Harry Howard - Tulane University

LOCALIZACIÓN DE ELECTRODOS 04/18/11 9 SPAN Harry Howard - Tulane University

EXPERIMENTO 1, GRAND AVERAGES, N = 22 04/18/11 10 SPAN Harry Howard - Tulane University Grand averages of the target words for the agreement, gender disagreement, and number disagreement conditions, in article–noun pairs (left) and in noun–adjective pairs (right). Vertical line marks the onset of target word presentation (t = 0). Six representative electrodes are represented (see locations in Figure 7).

MAPAS TOPOGRÁFICOS 04/18/11 11 SPAN Harry Howard - Tulane University Maps were computed from values resulting from the subtraction between agreement and disagreement waves (gender and number conditions collapsed).
