This study examined the influence of phonotactic probability on word recognition in English-speaking toddlers. Typically developing toddlers completed a preferential looking paradigm using familiar words, which consisted of either high or low phonotactic probability sound sequences. The participants' looking behavior was recorded in response to correctly-produced and incorrectly-produced forms of familiar words. Results indicate that toddlers were more sensitive to mispronunciations of high probability words as compared to low probability words. Toddlers' word recognition skills were more closely related to the frequency with which they have heard and produced phonological sequences, rather than word familiarity. These findings are discussed in terms of toddlers with expressive language delay.
