Noelia Valle, an education expert and professor of physiology at the Universidad Francisco de Vitoria in Spain, shares insights on studying effectiveness, highlighting a common misconception that more study hours lead to better retention of knowledge. Valle uses an analogy of trying to fill a bottle with water using a high-powered fire hose, illustrating that just like the water spills over, excessive study time can overwhelm the brain rather than facilitate learning.

In her discussion with BBC Mundo, Valle emphasizes that the human brain learns through integration rather than mere accumulation of information. This is linked to two critical concepts: working memory and cognitive load. Valle argues that when the cognitive load is too high, the brain struggles to process and store information effectively, which can hinder learning. Instead of merely increasing study time, students should focus on methods that help integrate and understand information.

Valle advocates for a strategic approach to studying, pointing out that less can be more when engaging with learning materials. By prioritizing quality over quantity, students can enhance their learning efficacy, leading to better academic outcomes. This perspective challenges traditional notions about study habits and encourages a reevaluation of how students approach their educational methods, suggesting a need for educational reform that incorporates these findings.
