Brain Training: Fact or Fiction in Improving IQ?

Brain training has become quite popular in recent years, promising to improve cognitive function and even increase IQ. But is there any truth to these claims, or is it just another fad?

First, it’s important to understand what we mean by “brain training.” Essentially, it involves engaging in a series of mental exercises or games designed to improve specific cognitive skills, such as attention, memory, and processing speed.

Proponents of brain training point to several studies that seem to support its effectiveness. For example, a 2014 study published in the Journal of Neuroscience found that just ten hours of brain training led to increased activation in regions of the brain associated with cognitive control.

However, other studies paint a different picture. A 2016 study published in the Journal of Experimental Psychology found no improvement in cognitive function following six weeks of brain training. And a 2017 review of 75 studies on brain training found only small, short-term improvements in cognitive function that did not translate to real-world benefits.

So, what’s the truth? While there is evidence to suggest that brain training can lead to measurable changes in the brain, it’s still unclear whether these changes actually improve overall cognitive function or IQ. And even if brain training does lead to improvements in specific skills, it’s not clear whether these skills generalize to real-world tasks.

At the end of the day, it’s important to approach brain training with a healthy dose of skepticism. While it may have some benefits for certain individuals, it’s unlikely to be a one-size-fits-all solution for improving IQ or cognitive function. Instead, it’s important to focus on a holistic approach to brain health that includes proper nutrition, exercise, and rest.
