Resumen

Se ha debatido si la atención o los colores pueden modular la velocidad de procesamiento de las modalidades visuales en los hemisferios cerebrales. Estudios electrofisiológicos han demostrado que la atención o los colores modulan las primeras etapas de la actividad neuronal cerebral cuando se procesaron estos estímulos. Sin embargo, no se han investigado los efectos simultáneos de la atención y el color sobre la velocidad del procesamiento de textos árabes en ambos hemisferios cerebrales. Estudiamos los efectos combinados de la atención y los colores en el hemisferio cerebral derecho e izquierdo. En dos experimentos, los estímulos de palabras se presentaron en diferentes longitudes, y los colores en los hemicampos derecho e izquierdo al azar. Se instruyó a los participantes a detectar el color específico de la palabra usando dedos índice. Los resultados informaron que los tiempos de reacción "RTs" se incrementaron cuando las letras de las palabras disminuyeron, y fueron más largos en el hemicampo derecho que en el izquierdo para palabras de color blanco y verde. Se informó de un patrón opuesto para las palabras de color rojo y azul, en que los RTs eran más largos en el hemicampo izquierdo que derecho. Los hallazgos sugieren que los colores pueden modular la velocidad de procesamiento del hemisferio cerebral ante estas modalidades visuales. Además, la atención puede cambiar la forma en que la corteza cerebral está respondiendo a palabras en colores con diferente longitud. En conclusión, estos hallazgos sugirieron que los efectos combinados de la atención y los colores, modulan la velocidad de procesamiento en los hemisferios cerebrales.
