The early childhood years are crucial for making these connections. Brain connections enable us to move, think, communicate and do just about everything.
A newborn baby has all of the brain cells (neurons) they’ll have for the rest of their life, but it’s the connections between these cells that really make the brain work. The brain is the command center of the human body. It keeps growing to about 80% of adult size by age 3 and 90% – nearly full grown – by age 5. Incredibly, it doubles in size in the first year. Watch our video on early childhood brain development:ĩ0% of Brain Growth Happens Before KindergartenĪt birth, the average baby’s brain is about a quarter of the size of the average adult brain. The quality of a child’s experiences in the first few years of life – positive or negative – helps shape how their brain develops. And early brain development has a lasting impact on a child’s ability to learn and succeed in school and life. As with all scientific research, there is also a risk of publication bias.From birth to age 5, a child’s brain develops more than at any other time in life. These results are promising, but more research is needed to determine the connection between improved assessment scores and everyday tasks in participants' lives.įuture research should address the risk of inadvertent experimenter bias and the risk of attrition bias in this study, as both the Lumosity and crossword groups had approximately 50% attrition rate.
In it, half of the 4,715 participants who completed the study trained five days per week, for fifteen minutes each day on Lumosity while the other half did online crossword puzzles as an active control.Īfter 10 weeks, Lumosity users improved more than the control group on our assessments of working memory, short term memory, processing speed, problem solving, fluid reasoning, and overall cognitive function. Lumos Labs conducted a randomized study of Lumosity brain training and published the results in a peer-reviewed research journal.
