"I showed my daughter a counting video and wondered just how she would react," said Wang, assistant professor of cognitive psychology in the School of Arts and Sciences at Rutgers University-New Brunswick. "The literature was mixed. Some said it wouldn't work but my daughter gave me the opposite result. She did respond and reacted to the counting she was seeing on the video."

A recent study by Wang of 81 babies between 14 and 19 months old published in Developmental Psychology found the same outcome. When these babies watched a video where they were shown pictures of toy cars and toy pigs and listened to someone count out loud prior to the toys being hidden in a box -- similar to an earlier study done in person -- the babies looked longer when the box was lifted and some of the objects disappeared. When there was no out loud counting and just pointing in the video, the babies became distracted and looked away, similar to the same earlier study done in person.
