Luckner and colleagues (2005/2006) identified 964 articles related to literacy and deaf individuals
over a 40-year period, a finding that attests, at least, to the importance of the issue. Yet Luckner and colleagues found only 22 of those studies sufficiently rigorous, complete, and relevant to be included in a meta-analysis of research results, and reported that "no two studies examined the same dimension
of literacy" (p. 443). In short, they found that educators and researchers do not know as much about deaf students' literacy as they think they do.
...language-rich early environments appear to be necessary for age-appropriate literacy skills, but
they do not appear to be sufficient. Rather, several studies have indicated that deaf children
whose early environments Include access to both sign language and the print/spoken vernacular" develop better literacy skills than those exposed only to one mode or the other (Akamatsu, Musselman, &. Zweibel, 2000; Brasel & Quigley, 1977; Padden & Ramsey. 2000; Strong & Prinz, 1997, 2000).
Although deaf children with cochlear implants frequently are found to read better than peers without implants, their mean levels of performance still rarely match those of hearing age-mates (Geers, 2005; Spencer, Tombiin, & Gantz, 1997). Emerging longitudinal data further suggest that even while such children continue to show language gains, their reading abilities may fall behind those of hearing peers in later grades (Geers, Tobey, Moog, & Brenner, 2008), when schooling demands that they read to learn and there is reduced emphasis on learning to read. A possible exception appears to be tbose students with implants who have the opportunity to use both spoken and sign language in school, a group that has been found to read at the same level as hearing peers, at least through high school (Spencer, Gantz, & Knutson, 2004).
There appears to be a naive assumption that underlies beliefs about reading and children with cochlear implants: that there is a direct relationship between hearing threshold and reading ability. Literacy does seem to be sensitive to hearing loss, but the relationship appears to be one in which even relatively small increases in hearing thresholds can disrupt reading ability, rather than one in which there is a direct link between the two.
Timms, Brien, Merrell, Collins, and Jones (2003), however, did not find a correspondence between hearing thresholds and composite reading scores among 5- and 6-year-olds. Among older deaf and hard-of-hearing students, Allen (1986) found that degree of hearing loss had little effect on academic achievement, as measured by the Stanford Acbievement Test, a finding replicated by Powers (2003) in his reanalysis of a large data set.
Marschark and Wauters argued that one reason for the lack of progress in this area might he that deaf students' reading challenges are not really specific to reading. The researchers observed that weaknesses exhibited by deaf students in many of the subskills involved in reading are paralleled by similar weaknesses in understanding sign language, and suggested that both therefore might better be accounted for in terms of more general language-comprehension and cognitive factors. In their view, understanding and improving reading comprehension skills among deaf students will require going beyond the most commonly studied aspects of deaf students' reading—phonology, vocabulary,
morphology, and grammar—and considering differences in higher-level language and cognitive processes.
This notion is captured in Paul's view of reading as involving interactions among text factors, reader factors, and task/context factors, and in the more general notion of reading as involving both top-down and bottom-up processing (i.e., between what is known and what is on the primed page).
…tbe possibility that rather than continue to search for explanations of deaf students' difficulties with text, it mighi be more fruitful to examine relations of cognitive processing, language comprehension, and learning, regardless of whetber the latter twoinvolve printed words or througb-the-air communication. In this view, if deaf students have full perceptual access to both print and sign language and demonstrate similar difficulties in learning through those media. it is unlikely that discussions of English phonology or grammar, or any other text variables, will be sufficient to overcome reading challenges. Rather, a focus on reader variables such as lexical knowledge, metacognition, and informat ion-processing strategies and habits in the context of language at large would be in order.
A related explanation for the advantage of reading over learning from sign or speecb is the evanescence of through-the-air communication. We suggested earlier in the present article that deaf students' seeing sign can be considered functionally equivalent to hearing students' hearing speech for the purposes of interpersonal communication, and the two modalities share the linguistic quality of rapid fatling. Michaei, Keller, Carpenter, and Just (2001) observed very different patterns of brain activity when bearing individuals heard or read identical sentences, an indication of qualitative differences
between the two ways of processing information. Michael and colleagues suggested that listening requires much more processing—as well as greater utilization the memory resources—than reading, in large measure because of rapid fading. With printed text, in contrast, the reader can control how fast words are processed, and portions of the text can be re-read to provide context or disambiguation of more difficult or misread segments (an option not available with real-time text).

Okay. Those of you who follow my posts regarding literacy, language, and cognition...how many times have you seen me post exactly what is being stated in this article? We have discussed the issues of higher thinking, top down and bottom up processing, and the fact that auditory stimuli require more, as well as a different type, of processing.
And please note the use of "language rich environments" not spoken language rich environments" nor "English rich environments".
Again, discuss away.
