The literature to date suggests that the best predictor of early reading ability, phonological awareness, appears to be associated with the acquisition of letter-sound and vocabulary knowledge and with the development of well-defined phonological representations. It further suggests that at least some aspects of phonological awareness critically depend upon literacy exposure. In this study of 4- to 6-year-olds, we examine whether aspects of the home literacy environment are differentially associated with phonological awareness. Parental responses to a questionnaire about the home literacy environment are compared to children's awareness of rhyme and phonemes, as well as to their vocabulary, letter knowledge, and performance on measures of phonological strength (nonword repetition, rapid naming skill, phonological distinctness, and auditory discrimination). The results showed that a teaching focus in the home literacy environment and exposure to reading-related media are directly associated with phoneme awareness and indirectly associated via letter knowledge and vocabulary. Exposure to reading-related media and parents' active involvement in children's literature were also directly and indirectly linked with rhyme awareness skills via their association with letter and vocabulary knowledge.

Previous research has shown a clear relationship between phonological awareness and early reading ability. This article concerns some aspects of spoken language skill that may contribute to the development of phonological awareness, as manifested in rhyme awareness and phoneme awareness. It addresses the hypothesis that phonological awareness abilities are associated with measures that purportedly tap into the strength of phonological representations. We examined rhyme awareness, phoneme awareness, articulatory skill, speech perception, vocabulary, and letter and word knowledge in 40 children, aged 4 to 6, who were just beginning to be exposed to formal reading experiences in private preschools. The children also received cognitive tests and tests of reading ability. The results did not validate strength of phonological representation as a unitary construct underlying phonological awareness more generally, but instead revealed a selective pattern of associations between spoken language tasks and aspects of phonological awareness. Speech perception was closely associated with rhyme awareness measures when age, vocabulary, and letter knowledge were controlled. Children with a less developed sense of rhyme had a less mature pattern of articulation, independent of age, vocabulary, and letter knowledge. Phoneme awareness was associated with phonological perception and production. Children with low phoneme awareness skills showed a different pattern of speech perception and articulation errors than children with strong abilities. However, these differences appeared to be largely a function of age, letter knowledge, and especially vocabulary knowledge.

Letter sound knowledge, which, together with phonological awareness, is highly predictive of pre‐school children's reading acquisition, derives from children's knowledge of their associated letter names and the phonological patterns of those names. In this study of 66 monolingual pre‐school children we examined whether phonological patterns between letter names and their associated sounds might be differentially associated with aspects of phonological awareness. Results suggest that rudimentary levels of phonological awareness may facilitate the learning of letter sound associations. However, more explicit phonological awareness appears to be linked bi‐directionally with letter sound knowledge with diverse name‐sound associations, with letter sound associations that do not follow regular patterns (e.g. ‘juh’ for ‘j’ and ‘huh’ for ‘h’) most closely associated with performance in more complex phoneme awareness tasks.

The female steroid hormone 17beta-estradiol enhances synaptic transmission and the magnitude of longterm potentiation (LTP) in adult rodent hippocampal slices. Long-term depression (LTD), another form of synaptic plasticity, occurs more prominently in hippocampal slices from aged rodents. A decrease in LTP has been recorded in hippocampal slices from adult rodents behaviorally stressed just before tissue preparation and electrophysiological recording. Here, the authors test the hypothesis that estrogen modifies synaptic plasticity in both adult and aged rodents, whether behaviorally stressed or not. Our results indicate that estrogen enhances LTP and attenuates LTD, thus producing a protective effect against both aging and stress. These results also provide new approaches that can be used to reverse age and stress-related learning and memory dysfunction.
