Assessing linguistic competence: when are children hard to understand?*
Published online by Cambridge University Press: 26 September 2008
Abstract
It is argued that previous assessments of children's knowledge of the hard to see type of construction were confounded by a variety of extra-linguistic factors. Therefore, the relatively delayed age of comprehension previously reported (6½–8 years) may have been due to younger children's deficiencies in extralinguistic skills. In the present study, with these extralinguistic complications eliminated, the passing age was found to be 5 years, and even 4-year-olds evidenced considerable knowledge of the target structure. Other findings were: variation in sentence difficulty as a function of the syntactic and/or aspectual character of the verb; high test–retest reliability at all levels of performance; and a necessary-but-not-sufficient empirical relation between comprehension of the target construction and the passive. Results are discussed in terms of their implications for the acquisition of this particular structure and for the general problem of detecting linguistic competence from performance.
