Research from Concordia University in Montreal reveals a new perk visible in the problem-solving skills of bilingual toddlers. The study assessed the vocabularies of 39 bilingual children and 43 monolinguals when they were aged 24 months, and then again at 31 months. During the second assessment, the researchers also had the young participants perform a battery of tasks to test their cognitive flexibility and memory skills. While overall, there was little difference between the bilingual and monolingual toddlers, bilingual children performed significantly better on the conflict inhibition tasks than did their monolingual counterparts. Conflict inhibition refers to the mental process of overriding a well-learned rule that you would normally pay attention to. These were the two tasks: 1. Reverse categorization -- participants were told to put a set of little blocks into a little bucket and big blocks into a big bucket. Then the instructions were switched -- big blocks in the little bucket and little blocks in the big bucket. 2. Shape conflict -- participants were shown pictures of different sized fruit and asked to name them. Then a new series of images was shown, with a small fruit embedded inside a large one. Toddlers were asked to point to the little fruit. Crivello, one of the lead researchers, commented that "Language switching underlies the bilingual advantage on conflict tasks. In conflict inhibition, the child has to ignore certain information -- the size of a block relative to a bucket, or the fact that one fruit is inside another. That mirrors the experience of having to switch between languages, using a second language, even though the word from a first language might be more easily accessible."
