Playing with building blocks may help toddlers improve their cognitive development, especially their language skills, say scientists.
Researchers in the US studied 175 children, aged between one-and-a-half to two-and-a-half years. While 88 were sent two sets of building blocks and two newsletters with suggestions for parents about activities that could be done with the blocks, the other 87 children were not sent any blocks until the study had been completed.

"We found that distributing blocks was associated with significantly higher language scores in a sample of middle and low-income children," said Dimitri A. Christakis at University of Washington, who led the team of researchers.
Scientists said that the children who had received blocks had an average language assessment score 15 percent higher than the other children, reported health portal Medical News Today.
The children who play with blocks are likely to have better cognitive development -- a process by which the brain develops the abilities to think, learn and remember. It enables a child to solve problems and understand concepts, the study said.
Playing with blocks is nowadays often being replaced with other activities like watching TV that do not encourage language development, the researchers said in the latest issue of the Archives of Paediatrics and Adolescent Medicine published by American Medical Association.
Christakis however said it was a pilot project and required further study to corroborate the findings.
