Recent studies in cognitive psychology have challenged the traditional view that multitasking enhances productivity. Researchers have found that the human brain is not designed to process multiple complex tasks simultaneously; instead, it rapidly switches attention between tasks, leading to a phenomenon known as 'attention residue.' This residue impairs performance on subsequent tasks because mental resources remain partially engaged with the previous activity. Furthermore, neuroimaging data reveal that heavy multitaskers show reduced activity in brain regions associated with sustained attention and working memory, compared to light multitaskers. These findings suggest that while multitasking may feel efficient, it often results in slower completion times and more errors, particularly for tasks requiring deep concentration.
❓ Según el pasaje, ¿cuál es la razón principal por la que la multitarea es ineficiente?
A. A. El cerebro no puede manejar múltiples tareas a la vez y deja residuos mentales que interrumpen la concentración.
B. B. La multitarea reduce la actividad en todas las regiones del cerebro, provocando un deterioro cognitivo general.
C. C. Los multitarea intensivos tienen menos capacidad de memoria de trabajo que los multitarea ligeros.
D. D. Las tareas que requieren una concentración profunda son imposibles de completar cuando se realiza multitarea.
✅ 正确答案
A. The brain cannot handle multiple tasks at once and leaves mental residue that disrupts focus.
