1 LA NEUROSINTAXIS 4 18 ABR 2011 – DÍA 39 Neurolingüística del español SPAN 4270 Harry Howard Tulane University

2 ORGANIZACIÓN DEL CURSO Neurospan/ El curso es apto para un electivo en neurociencia. Neurolinguistics and linguistic aphasiology está en reserva en la biblioteca. Human Research Protection Program Before beginning research at Tulane University, all research personnel must complete the CITI Training Program; this can be completed at 04/18/11 2 SPAN Harry Howard - Tulane University

3 REPASO Es la prueba. 04/18/11 SPAN Harry Howard - Tulane University 3

4 NEUROCOGNITIVE MODEL OF AUDITORY SENTENCE PROCESSING 04/18/11 4 SPAN Harry Howard - Tulane University

5 B RODMANN AREAS IN THE LEFT HEMISPHERE 04/18/11 5 SPAN Harry Howard - Tulane University Inferior frontal gyrus (IFG) = green, Superior temporal gyrus (STG) = red Middle temporal gyrus (MTG) = blue

6 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

7 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

8 ¿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

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

10 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).

11 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).

12 EXPERIMENTO 2, GRAND AVERAGES, N = 24 04/18/11 12 SPAN Harry Howard - Tulane University

13 MAPAS TOPOGRÁFICOS 04/18/11 13 SPAN Harry Howard - Tulane University

14 DIFFERENCE WAVES (AGREEMENT LESS DISAGREEMENT) COMPARING GENDER AND NUMBER ACROSS BOTH SENTENCE POSITIONS 04/18/11 14 SPAN Harry Howard - Tulane University

15 EL PRÓXIMO DÍA Devolución de pruebas Quizás otro experimento sobre el español 04/18/11 15 SPAN Harry Howard - Tulane University
