Document Summary
Individual differences in language development: the case of socioeconomic status. Within the eld of communication sciences, we aim to categorize traits, behaviors and symptoms to typical and atypical groups. This is referred to as taxonomy, or a taxonomic scheme of classi cation. E. g. phonological skills can be typical or disordered. However, as within all social sciences, there is also great variation within these taxa. Within atypical group = variation in severity. Bell curve: we can give someone a standardized assessment (such as iq test) and we can compare how they perform to other peers of the same age. We have a mean, or an average. the average is in the middle of the bell curve. Not only children vary in their language skills at any given time, we can use repeated assessments at multiple time points to see individual differences in the rates and trajectories of their language development, such as in lexical development.
