Grammar structures and deaf and hard of hearing students: a review of past performance and a report of new findings.

Results of a study are presented that suggest the grammatical structures of English some deaf and hard of hearing students struggle to acquire. A review of the literature from the past 40 years is presented, exploring particular lexical and morphosyntactic areas in which deaf and hard of hearing children have traditionally exhibited difficulty. Twenty-six participants from an urban day school for the deaf used the LanguageLinks software, produced by Laureate Learning Systems, for 10 minutes daily for 9 weeks.

Which it is it? The acquisition of referential and expletive it.

The purpose of this study was to determine the natural order of acquisition of the proform it, comparing deictic pronoun it, anaphoric pronoun it and expletive it. Files from four children (Adam, Eve, Nina and Peter) aged 1;6-3;0 in the CHILDES database were coded for occurrences of NP it (here it is) and expletive it (it's raining). Occurrences of NP it were coded for whether they followed an overt discourse anaphor (anaphoric it) or not (deictic it).
