嬰兒筆電，嬰兒手機，交談農場，這些都是當前推出快速又先進的玩具，許多被當成激發嬰兒語言技能的工具行銷。
Baby laptops, baby cellphones, talking farms — these are the whirring, whiz-bang toys of the moment, many of them marketed as tools to encourage babies' language skills.
不過，新研究報告質疑這類電子玩具是否會使嬰兒跟父母的口頭交流減少，這種交流對認知發展極其重要。
But a new study raises questions about whether such electronic playthings make it less likely that babies will engage in the verbal give-and-take with their parents that is so crucial to cognitive development.
發表於「美國醫學會小兒科學期刊」的該研究報告發現，嬰兒與父母玩廣告中特別宣傳能促進語言發展的電子玩具時，父母說話及對嬰兒發聲的回應，要比玩傳統玩具如積木或閱讀硬頁書時來得少。嬰兒玩電子玩具時發聲也較少。
The study, published in JAMA Pediatrics, found that when babies and parents played with electronic toys that are specifically advertised as language-promoters, parents spoke less and responded less to baby babbling than when they played with traditional toys like blocks or read board books. Babies also vocalized less when playing with electronic toys.
帶領研究的弗拉格斯塔夫北亞利桑納大學傳播科學與溝通障礙副教授安娜．索沙說：「我的直覺是，他們讓嬰兒跟玩具互動，自己退居一邊。」
"My hunch is that they were letting the baby interact with the toy and they were on the sidelines," said Anna V. Sosa, an associate professor of communications science and disorders at Northern Arizona University in Flagstaff, who led the study.
這項研究建立在日漸增多的一些研究結果之上，既有結果顯示電子玩具和電子書可能使父母較少與小孩進行最有意義類型的口語交流。
天普大學心理學教授凱西．赫許帕塞克說：「當使用這類工具與裝置時，父母們就會閉口。你做的是更多行為規範，像是『別碰那』或『做這個』，甚至啥也不做，因為電子書與玩具已代勞了。」赫許帕塞克未參加上述研究，但此前對電子書跟電子形狀分類盒的研究有類似發現。The study builds on a growing body of research suggesting that electronic toys and e-books can make parents less likely to have the most meaningful kinds of verbal exchanges with their children.
"When you put the gadgets and gizmos in, the parents stop talking," said Kathy Hirsh-Pasek, a professor of psychology at Temple University who was not involved in the new study, but who has found similar effects with e-books and electronic shape-sorters. "What you get is more behavioral regulation stuff, like 'don't touch that' or 'do this,' or nothing because the books and toys take it over for you."
她並補充道：「玩玩具應是玩具只占10%，90％由小孩做主，許多這些電子玩具卻是玩具占了90%以上，小孩只能補白。」
索沙說，她對結果感到驚訝。她原本預期一些父母嬰兒組玩某種玩具時說話較多，而其他組則是在玩另種玩具時說較多話。
She added, "A toy should be 10 percent toy and 90 percent child, and with a lot of these electronic toys the toy takes over 90 percent and the child just fills in the blank."
Sosa said she was surprised by the results. She had expected some parent-baby pairs would talk more with one type of toy, while others would talk more with another.
然而，結果卻幾乎一致。玩電子玩具時父母平均每分鐘說40字，少於玩傳統玩具的56字，及讀書時的67字。
But the results were consistent almost across the board. When electronic toys were being used, parents said about 40 words per minute, on average, compared with 56 words per minute for traditional toys and 67 words per minute with books.
這是個小型研究，共26個家庭參與，多為受過良好教育的白人家庭。因此研究人員說，若以更大、更多樣化的群體為研究對象，結果可能不同，但這個研究仍值得注意，因為它盡力捕捉現實世界中無研究人員觀看下的居家親子遊戲時間。
The study was small — 26 families — and most were white and educated. So the researchers say the results might be different with a larger and more diverse group. But the study is notable because it sought to capture real world parent-child playtime in their homes without researchers watching.
