Educational baby videos do not appear to improve the overall general language learning of 12 to 24 months old children, nor do they help them pick up words featured in the program, a survey has found.
According to the report, children age 2 and younger spend an estimated two hours per day exposed to media on a screen, and the average age at which infants begin watching programming designed for their age group is five months.
Manufacturers' claims that these infant-directed media can teach children specific vocabulary words have not been substantiated.
Rebekah A. Richert, Ph.D., and colleagues at the University of California, Riverside, studied vocabulary acquisition among 96 children age 12 to 24 months.
Participants were tested on measures of vocabulary and general development, and their primary caregivers (77 mothers, seven fathers and four others) answered a series of questions about their children's development and previous exposure to educational media.
Half of the children were then given an educational DVD to watch in their homes.
When additional tests were conducted after six weeks, there was no evidence children learned the words specifically highlighted in the DVDs, and watching the DVDs was unrelated to measures of general language learning.
