Transfer of Training
The degree to which skills or knowledge learned in one context carry over to performance in a different, untrained context.
Transfer is the central question in cognitive fitness: does getting better at puzzles make you better at anything else? The honest answer: it depends on what kind of transfer you're looking for. Near transfer (improvement on tasks similar to what you practiced) is well-supported by research. Far transfer (improvement on very different real-world tasks) is harder to demonstrate and remains actively debated. The strongest transfer evidence comes from processing speed. The ACTIVE trial found that speed-of-processing practice not only improved speed on untrained tasks but also reduced car accident rates and — most dramatically — cut dementia risk by 29% over 10 years. Effective cognitive programs maximize transfer potential by practicing diverse skills across multiple cognitive domains rather than drilling a single narrow task.
Frequently Asked Questions
Does brain training transfer to real life?
Near transfer (similar tasks) is well-established. Far transfer (very different tasks) is less consistent but not zero. The strongest real-world transfer evidence: the ACTIVE trial showed speed training reduced car accidents and dementia risk. Working memory training shows modest transfer to attention and reasoning tasks. The key is training diverse cognitive domains — single-task training produces narrower transfer than multi-domain training.
Why does processing speed training show the best transfer?
Processing speed is foundational — it affects the efficiency of virtually every other cognitive process. When you process information faster, you free up working memory capacity for complex reasoning. This is why speed improvements cascade across other domains. It's also why the ACTIVE trial found speed training (not memory or reasoning training) produced the broadest real-world benefits.
