Canadian scientists say that pre-schoolers can improve their verbal intelligence within 20 days of classroom instruction using interactive, music-based cognitive training cartoons.
In the study, 48 pre-schoolers four to six years of age participated in computer-based, cognitive training programs that were projected on a large classroom wall and featured colorful, animated cartoon characters delivering the lessons.
AdvertisementThe children were divided into two groups. One group received music-based, cognitive training that involved a combination of motor, perceptual and cognitive tasks, and included training on rhythm, pitch, melody, voice and basic musical concepts.
The other group received visual art training that emphasized the development of visuo-spatial skills relating to concepts such as shape, color, line, dimension and perspective.
Each group received two training sessions of one-hour duration each day in classroom, over four weeks, led by instructors at The Royal Conservatory in Toronto.
The verbal IQ tests assessed the children's attention, word recall and ability to analyze information and solve problems using language-based reasoning. Brain imaging enabled researchers to detect if functional brain changes had occurred related to the cognitive training.
When the children were re-tested five to 20 days after the end of the training programs, researchers did not find any significant increase in verbal intelligence or brain changes for the children who participated in the visual art training module.
However, they found quite a different result in the children who took the music-based, cognitive training. Ninety percent of those children exhibited intelligence improvements - five times larger than the other group - on a measure of vocabulary knowledge, as well as increased accuracy and reaction time. The music group also showed brain changes that co-related to their enhanced cognitive performance.
"Our data have confirmed a rapid transfer of cognitive benefits in young children after only 20 days of training on an interactive, music-based cognitive training program. The strength of this effect in almost all of the children was remarkable," said lead researcher Dr. Sylvain Moreno, a world expert on neuroeducation.
The findings have exciting implications for conceptualizing and improving neuroeducation programs for children of all ages, and potentially for older adults.
The study has been published online in the journal Psychological Science.
