Recent studies in cognitive psychology have challenged the traditional view that multitasking enhances productivity. Researchers such as Rubinstein and colleagues (2001) demonstrated that task-switching incurs a cognitive cost, as the brain requires time to refocus attention after each interruption. This phenomenon, termed 'attention residue', suggests that even brief diversions can impair performance on complex tasks. Furthermore, neuroimaging data indicate that the prefrontal cortex, responsible for executive control, shows reduced efficiency when processing multiple streams of information simultaneously. These findings imply that in academic or professional settings, prioritizing sequential focus over concurrent task management may lead to higher quality outcomes and fewer errors.
❓ 지문에 따르면, '주의 잔여(attention residue)'가 과업 수행에 미치는 주요 함의는 무엇인가?
A. A. 멀티태스킹은 정보를 동시에 처리할 수 있게 함으로써 효율성을 향상시킵니다.
B. B. 짧은 중단은 인지적 재집중 시간으로 인해 복잡한 작업의 수행에 부정적인 영향을 미칠 수 있다.
C. C. 전전두피질은 여러 작업을 동시에 처리할 때 더 효율적으로 작동하게 된다.
D. D. 순차적 집중은 오류를 줄이는 데 있어 멀티태스킹보다 덜 효과적이다.
✅ 正确答案
B. Brief interruptions can negatively affect performance on complex tasks due to cognitive refocusing time.
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)
