One of the most striking developments in children’s first few years of life is just how quickly they learn language. This is despite the fact that children’s abiltiies to control their attention and remmeber information are still developing. One potential explanation for why children learn so quickly despite their immature cognitive systems is that the language they hear is different from the language that adults hear. If you think about how we talk to children, you’ll probably notice a number of ways in which we simplify our speech. One hypothesis about child-directed directed speech is that it is not just simpler that adult-directed speech across the board, but that it might be specially calibarted to children’s developing linguistic and cognitive abilities: Caregivers might tune the information they provide to keep it at the right level of complexity.

In this lab we’ll be looking at data from a recent paper from my lab in which we asked from parents and their children playing a simple reference game. On each round of the game, children saw three animals on the screen of an iPad, and parents goal was to use language to communicate to their child which target animal they should choose (see below). The primary measure of interest in this study was how many words parents used to communicate to their child. In line with the tuning hypothesis, we predicted that parents should use more words to talk to their children about animals that they are less likey to know.
