A study involving 11,430 participants tested the effectiveness of computerized brain training. Participants were divided into three groups: two experimental groups trained on specific cognitive tasks and a control group that answered obscure questions. The study found that while participants improved on the tasks they trained on, there was no evidence of transfer effects to untrained tasks. Both experimental groups showed significant improvements on the tasks they practiced, with large effect sizes. However, the control group also showed some improvements, though smaller. The results suggest that computerized brain training does not lead to general cognitive improvements beyond the specific tasks trained. The study highlights that the benefits of training are task-specific and do not generalize to other cognitive functions. The findings challenge the widespread belief that brain training enhances general cognitive function. The study also notes that the amount of training did not correlate with general cognitive improvements, and that the effects observed were likely due to task repetition rather than general cognitive enhancement. The results indicate that computerized brain training does not provide significant general cognitive benefits in healthy adults.A study involving 11,430 participants tested the effectiveness of computerized brain training.
