Abstract

We asked whether there is evidence to support the existence of the vocabulary spurt, an increase in the rate of word learning that is thought to occur during the second year of life. Using longitudinal data from 38 children, we modeled the rate of word-learning with two functions, one with an inflection point (logistic), which would indicate a spurt, and one without an inflection point (quadratic). Comparing the fits of these two functions using likelihood ratios, we found that just 5 children had a better logistic fit, indicating they underwent a spurt. The implications for theories of cognitive and language development are considered.
