Recent studies in cognitive neuroscience have revealed that the human brain's capacity for multitasking is largely illusory. When individuals attempt to perform two complex tasks simultaneously, the prefrontal cortex rapidly switches between them rather than processing both at once. This switching incurs a 'cognitive cost,' manifesting as reduced accuracy and slower reaction times. Moreover, habitual multitaskers often exhibit poorer performance on tasks requiring sustained attention, suggesting that the neural pathways associated with focused concentration may be weakened by frequent task-switching. These findings challenge the popular belief that multitasking enhances productivity, implying instead that sequential task management might be more efficient for complex cognitive work.
❓ Каков основной вывод, сделанный исследователями относительно многозадачности?
A. A. Многозадачность повышает когнитивную эффективность при выполнении сложных задач.
B. B. Мозг может одновременно обрабатывать несколько сложных задач без ошибок.
C. C. Многозадачность менее эффективна, чем сосредоточение на одной задаче за раз, при выполнении сложной работы.
D. D. Лица, привыкшие к многозадачности, обладают более сильными нейронными связями для устойчивого внимания.
✅ 正确答案
C. Multitasking is less effective than focusing on one task at a time for complex work.
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
