This study investigated predictive relations between preschoolers' (N=310) behavioral regulation and emergent literacy, vocabulary, and math skills. Behavioral regulation was assessed using a direct measure called the Head-to-Toes Task, which taps inhibitory control, attention, and working memory, and requires children to perform the opposite of what is instructed verbally. Hierarchical linear modeling (HLM) was utilized because children were nested in 54 classrooms at 2 geographical sites. Results revealed that behavioral regulation significantly and positively predicted fall and spring emergent literacy, vocabulary, and math skills on the Woodcock Johnson Tests of Achievement (all ps<.05). Moreover, growth in behavioral regulation predicted growth in emergent literacy, vocabulary, and math skills over the prekindergarten year (all ps<.05), after controlling for site, child gender, and other background variables. Discussion focuses on the role of behavioral regulation in early academic achievement and preparedness for kindergarten.

There seems to be a substantial benefit for both speech and vocabulary outcomes when children receive their implant before the age of 2.5 yr. This benefit may combine a burst of growth after implantation with the impact of increased length of use at any given age. The added advantage (i.e., burst of growth) diminishes systematically with increasing age at implantation.

Preschoolers' (N ϭ 156) classroom language and literacy experiences, defined across multiple dimensions, and their vocabulary and emergent literacy development were investigated. Videotaped classroom observations revealed substantial variability in amount and types of language and emergent literacy activities, across classrooms and for individual children within classrooms. Generally, more time in emergent code-focused activities was associated with preschoolers' alphabet and letter-word recognition growth, whereas more time in meaning-focused activities (e.g., book reading) was related to vocabulary growth. Only teacher-and teacher-child-managed activities were associated with alphabet and letterword growth, whereas child-managed experiences, including play, were also associated with vocabulary growth. Overall, the effect size for student-level, code-focused instruction (small group) was about 10 times greater than was its classroom-level (whole-class) counterpart. There were Child ϫ Instruction interactions, with the impact of different activities varying with preschoolers' incoming vocabulary and emergent literacy.

The purpose of this paper is to provide a review of past and current research regarding language and literacy development in children with mild to severe hearing impairment. A related goal is to identify gaps in the empirical literature and suggest future research directions. Included in the language development review are studies of semantics (vocabulary, novel word learning, and conceptual categories), morphology, and syntax. The literacy section begins by considering dimensions of literacy and the ways in which hearing impairment may influence them. It is followed by a discussion of existing evidence on reading and writing, and highlights key constructs that need to be addressed for a comprehensive understanding of literacy in these children.
