So, what we\u2019re doing right now is-this is part of a much larger study where babies from lots of different language communities were tested on their preference for infant-directed speech. And all of the original study was done in English infant-directed speech. And now we\u2019re testing babies in other languages, like in this case Norwegian. <\/p>\n\n\n\n

There\u2019s been a big change in how we think about doing infancy research. So in the old days it was each lab was doing its own little research project and you\u2019d have \u2013 you know, it\u2019s very hard to recruit infant participants and it\u2019s hard to run those studies so we\u2019d have these very small samples. And it\u2019s just really hard to know when you\u2019re comparing across studies, one that was done in Winnipeg and another one that was done in Paris. When you see differences, whether those differences have to do with the differences across those populations or across the languages or the ages of the babies or something about the differences in how the methods are run across the different labs. And they\u2019re also really small samples which can limit our ability to interpret what we find. <\/p>\n\n\n\n
So, there\u2019s been this push to collect data in a much grander scale where we\u2019re sharing our procedures across different labs. In the study called the Many Baby Study that actually is close to 70 laboratories who were all collecting data for the same project. So, we can look at differences that have to do with subtle differences in how you run the method or differences in language or age at a scale that you just couldn\u2019t do with these sort of individual laboratory tests. <\/p>\n\n\n\n
When you\u2019re running a study that is international and large scale like this, one of the challenges is to figure out if, because it\u2019s a language study, what language you\u2019re going to actually do the test in. So, in general about, I\u2019m not sure of the exact numbers but somewhere probably around 90 percent of published studies are in North American English. So, there\u2019s this huge bias in our understanding of how language development works towards the peculiarities of the English language. And our European colleagues are always, for good reason, complaining about this. So when you do a grand study you want to be cognizant of those biases but at the same time because you\u2019re trying to base the research on the literature that\u2019s existing it \u2013 you know, you don\u2019t want to sort of randomly do a study in Norwegian without understanding how that fits in with the existing literature. <\/p>\n\n\n\n
So, the original large scale Many Baby Study was done with the English language. But now we have this problem that we\u2019ve now reinforced that bias. So that now there\u2019s an effort to do some of the same \u2013 to kind of repeat some of those tests with other languages to expand on our understanding of how this works not just in English but also across languages which is really, really important. <\/p>\n","protected":false},"excerpt":{"rendered":"
