A Fresh Look at Vocabulary Spurts
نویسندگان
چکیده
There is currently rather little agreement about the existence of, and explanation for, a vocabulary spurt in children during the second year. Here we apply a Functional Data Analysisbased technique called Automatic Maxima Detection to the problem of finding vocabulary spurts in a sample of 20 children. Even with considerable smoothing of the data, children were found to exhibit multiple vocabulary spurts of varying intensity and location. These results should provide a clearer target for researchers interested in detecting and explaining these deviations from linear growth.

متن کاملResearch : Brain Spurts and Piagetian Periods
A central question in the study of human development is the relation between cognitive and physical development.
