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.

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)
