Measures calculated from Baseline Snowman narrative speech sample using Quantitative Production Analysis procedures (described below). Normal values are presented in Table 5.
Frequency and length matched words, N=30 per word type (Berndt et al., 1997).
Subtests of Philadelphia Comprehension Battery (Saffran et al., 1988). Grammaticality judgments = proportion ill-formed sentences rejected (N=42); Comprehension of reversible sentences = sentence/picture matching using active, passive, locative and relative clause sentences (N=60).
Word span estimated (following procedures of Shelton, Martin, & Yaffee, 1992), from repetition of two, three and four-word lists controlled for frequency and imageability (Martin & Saffran, 1997). HD and KR were not tested.
