This practice has clear advantages: it allows to consume more content in less time, review more frequently or even avoid distractions by maintaining a more dynamic rhythm. However, researchers warn about this use.
Reproduce content at increased speed (either podcasts, audiobooks or virtual classes) It has become a custom, especially among the youngest. For many, see or listen to something in 1.5xo 2x is the standard. In fact, a survey conducted students from California revealed that 89% adjusted the reproduction speed of their online classes.
This practice has clear advantages: it allows to consume more content in less time, review more frequently or even avoid distractions by maintaining a more dynamic rhythm. In educational environments, you can also free time to review or practice.
See in 2x: how the accelerated speed of videos affects the brain
However, researchers warn that this acceleration is not harmless. Processing oral information involves key stages such as coding, storing and recovering what is heard. If the brain receives words at a pace too fast, the working memory (which has limited capacity) can collapse, causing cognitive overload and loss of information.
A recent analysis that gathered 24 experimental studies evaluated the impact of the reproduction speed on understanding. The result: at speeds up to 1.5x, the drop in performance was mild. But from 2x, the negative effects became significant. For example, a class understood to 75% at normal speed could be reduced to 58% if it was seen to 2.5x.

In addition, age influences. Older adults (61 to 94 years old) suffered more retention losses than young people (18 to 36 years old) when they saw accelerated videos, suggesting that the processing capacity also decreases over time.
It remains to be known if frequent training with rapid speeds can reduce these effects, or if it can have a long -term impact on brain function. For now, the evidence indicates that faster is not always better, and that deep learning requires time, attention … and perhaps return to 1x.
