Resumo

 

The goal of this study was to evaluate the influence of reading habits on cerebral plasticity in the performance of a discourse comprehension task in aging. The main hypothesis was that participants with higher frequency and quality of reading habits should exhibit reduced brain activity because the task should be easier for them. two groups of native French speakers, 16 young adults and 16 elderly adults, participated in a task using the nirS (near-infrared spectroscopy) technique. They read short stories and answered true or false probes after each one. They also completed a questionnaire about their previous reading habits. The results show that the more experienced readers had higher activation in the superior left region of the prefrontal cortex while they were reading the stories but lower activation in the same region when they were retrieving the information to answer the probe. Thus, more effort is required to acquire and maintain the information needed to answer, and this effort makes it easier to give the answer. These results reinforce the hypothesis that brain plasticity is promoted by cognitive activities throughout the lifespan.
