Recent studies in cognitive neuroscience have revealed that the human brain's ability to process language is not confined to a single region but relies on a distributed network of areas. The left hemisphere, particularly Broca's and Wernicke's areas, has long been associated with speech production and comprehension, respectively. However, modern imaging techniques, such as functional magnetic resonance imaging (fMRI), demonstrate that even simple language tasks activate a broad array of neural circuits, including those involved in memory and attention. Furthermore, research on bilingual individuals suggests that managing two languages enhances executive control functions, such as task switching and conflict resolution. This finding implies that language processing is dynamically intertwined with general cognitive abilities, challenging the traditional modular view of the brain. Consequently, educators and clinicians are urged to consider the holistic nature of linguistic competence when designing interventions for language disorders.
❓ ¿Cuál es la principal implicación de los estudios mencionados en el pasaje?
A. El procesamiento del lenguaje está controlado exclusivamente por las áreas de Broca y Wernicke.
B. El bilingüismo tiene un impacto negativo en funciones cognitivas como la atención.
C. La capacidad lingüística está estrechamente vinculada a procesos cognitivos más amplios, no solo a regiones cerebrales aisladas.
D. Las técnicas modernas de imagen han demostrado que la red del lenguaje del cerebro es estática.
✅ 正确答案
Language ability is closely linked to broader cognitive processes, not just isolated brain regions.
IELTS Reading Tips
Skim the questions first, underline keywords, then locate in the passage
Watch for paraphrasing; correct answers are often reworded
Be wary of absolute statements (all, always, never) — usually wrong
Pay attention to content after transition words (however, but, yet)
Manage time: about 20 minutes per passage; skip difficult questions first
