ABSTRACT

@#The most important characteristic of post-stroke anomic aphasia is disorder in nomenclature, but the location of brain injury has been unclear. In recent years, it was found that, based on T1WI of MRI, the location is uncertain in chronic anomic aphasia after stroke, but it is mostly in temporal lobe of the dominant hemisphere in acute stage. Based on diffusion tensor imaging, the subcortical white matter, especially the left subfrontal white matter plays an important role in the naming process. The fMRI studies found that anomic aphasia is related to the destruction of the connections among some specific gray matter brain regions, named brain network theory. The cognitive psychology theory suggested that language processing can be further divided into different steps, each step is responsible for different brain regions; for different kinds of words, such as verbs and nouns, the processing involves different regions.

ABSTRACT

Objetivo: este estudio compara el desempeño de dos grupos de participantes con y sin afasia anómica en tareas de decisión léxica (TDL) y de deletreo en relación con el efecto de las variables de frecuencia léxica y silábica. Materiales y métodos: se realizó un estudio prospectivo con un diseño 2x2x2, donde se administraron la TDL, en la cual cada participante debía decidir si el estímulo presentado correspondía a palabra o pseudopalabra y la tarea de deletreo, donde los participantes debían deletrear de forma oral cada una de las palabras presentadas auditivamente. Resultados: para la TDL, el grupo experimental presentó mayor porcentaje de error en los estímulos de alta frecuencia silábica, mientras que el control tuvo más errores en aquellos de baja frecuencia silábica. En cuanto a los tiempos de reacción, el grupo experimental tardó más que los controles en resolver la tarea. La tarea de deletreo no mostró diferencia de ejecución por grupos ni condiciones (frecuencia léxica y silábica). Conclusiones: los resultados del presente estudio demuestran el efecto de facilitación de la frecuencia léxica y la inhibición que genera la frecuencia silábica alta, ampliamente soportada por la investigación en población normatizada mediante diferentes lenguajes.


Objective: this study compares the performance of two groups of participants with and without aphasia anomic in a lexical decision tasks (LDT) and spelling, in relation to the effect of the variables of word frequency and syllable. Materials and methods: a prospective study with a 2x2x2 design, which administered the LDT, in which each she/he had to decide if it was a real Spanish word or not, pressing one of two keys. To the task of spelling, they had to spell orally each of words presented auditorily. Results: It was found that in the LTD, the experimental group made more errors in the high-frequency stimuli syllable while the control group had more errors in the low-frequency syllables. In terms of reaction times was evident that the experimental group took longer to solve the task than the control group. The spelling task performance showed no difference in groups or conditions (lexical frequency and syllable). Conclusions: similar than other researches in normalized population, the results of this study demonstrate the effect of lexical frequency facilitation and inhibition that generates high syllable frequency.


Objetivo: este estudo compara o desempenho de dois grupos de participantes com e sem afasia anómica em tarefas de decisão lexical (TDL) e de soletração em relação com o efeito das variáveis de frequência lexical e silábica. Materiais e métodos: realizou-se um estudo prospectivo com um plano 2x2x2, onde se administraram a TDL, e cada participante devia decidir se o estímulo apresentado correspondia a palavra ou pseudopalavra e a tarefa de soletração, onde os participantes deviam soletrar de forma oral cada uma das palavras apresentadas auditivamente. Resultados: para a TDL, o grupo experimental apresentou maior porcentagem de erro nos estímulos de alta frequência silábica, enquanto o controle teve mais erros naqueles de baixa frequência silábica. Com relação aos tempos de reação, o grupo experimental tardou mais que os controles em resolver a tarefa. A tarefa de soletração não mostrou diferença de execução por grupos nem condições (frequência lexical e silábica). Conclusões: os resultados do presente estudo demonstram o efeito de facilitação da frequência lexical e a inibição que gera a frequência silábica alta, amplamente suportada pela pesquisa em população normatizada mediante diferentes linguagens.
