In three typical phonological awareness tasks it was found that children with normal reading development sometimes give responses that are based on orthographic rather than phonological information. In dyslexic children, the number of occurrences of such orthographic intrusions was significantly lower. This effect cannot be explained by positing a lower degree of orthographic knowledge in dyslexic children since a group of younger children who had the same spelling level as the dyslexics also showed more orthographic intrusions. A plausible explanation for this difference between normal and dyslexic readers is that, in normal readers, phonological and orthographic representations of words are so closely connected that they are usually coactivated, even if such a coactivation is misleading. In dyslexics this connection is less strong, so that orthographic representations interfere less with phonemic segmentation. The relevance of this finding with respect to recent assumptions about the importance of phonology in establishing orthographic representations is discussed.

This study was designed to determine whether there was a relationship between the ease with which children make use of orthographic analogies and their progress in learning to read. The results of an experiment using a reading age match design showed that poor readers performed as well as normal readers on orally presented measures of onset/rime sensitivity, but less well on visually/orally presented rhyme tasks. The poor readers also performed less well than the normal readers on a task that measured the children's ability to take advantage of analogical units when reading lists of words: these reading lists contained groups of words that differed according to (1) whether the words containing the common unit were presented contiguously or noncontiguously, and (2) whether the unit constituted the rime portion of the words or was embedded within the rime portion of the words. A follow-up intervention study demonstrated that poor readers who received instruction in the use of orthographic analogies achieved higher reading accuracy scores on subsequent readings than did a matched group of poor readers who received standard remedial instruction in context cue usage.

This study examined the ability of young (mean CA = 29 years; SD = 3.67 years) and older adults (CA = 63 years; SD = 5.54 years) with mild to moderate mental retardation to produce complex sentences in naturalistic conversation. All of the complex sentences produced were coded into subcategories of complementation, relativization, or coordination. First, the overall proportion of complex utterances produced by each subject (based on the total number of utterances) was examined. Following this analysis, the well-formed production and productivity of the three general categories of complex sentences were considered. Individual complex sentences were then categorized by developmental level using Rosenberg and Abbeduto's (1987) acquisition scale. No significant differences were observed between the young and older groups.

Repeated reading of meaningful text has been shown to produce improvements in reading rate, fluency, and comprehension in readers of varying ability. The assisted repeated reading (ARR) method, which provides a fluent and expressive (i.e., prosodic) model, has been proposed as being particularly helpful in this regard. However, it is unclear which component of the ARR method (prosodic modeling or reading practice with intact text) is the most influential factor. The present study examined the effects of text practice and prosodic modeling on the reading rate, accuracy, expressiveness, and comprehension of 40 grade 5 disabled readers. Text practice and prosodic modeling were systematically varied to create four training conditions. Each subject read the first half of a set of stories three times under one of the four experimental conditions. Pretest and posttest measures of the dependent variables were analyzed for both the training passages and the second half of each story, on which no training occurred (transfer passages). While reading performance improved across all conditions, substantial additional gains were produced by the conditions that included the practice of intact text. Modeling of prosody did not produce significant additional gains. Transfer effects were limited, with only the ARR condition producing improved accuracy on the second half of the stories.

Children with specific language impairment (SLI) often show more limited use of grammatical morphology than younger, normally developing children matched according to mean length of utterance (MLU). However, within groups of children with SLI, individual differences are seen in grammatical morpheme use. In this study, we examined the role of weak syllable use in explaining some of these differences. Employing two different languages – English and Italian - children with SLI were placed into pairs. The children in each pair showed similar MLUs; however, one member of the pair showed a greater use of particular function words. In each of the pairs examined in both languages, the children with the greater use of function words also showed a greater use of weak syllables that did not immediately follow strong syllables. The weak syllable productions of children showing a more limited use of function words in each pair seemed to be dependent on a strong syllable-weak syllable production sequence. This sequence appeared to be operative across several prosodic levels, as defined within the framework of prosodic phonology. Because weak syllables that follow strong syllables usually have longer durations than those that precede strong syllables, the findings might have a perceptual basis. However, the results raise the possibility that limitations in prosody can restrict the degree of grammatical morpheme use by children with SLI.

This study examines the use and understanding of concordant (e.g., consequently, moreover) and discordant (e.g., rather, contrastively) adverbial conjuncts in the later part of the life span. The participants, 75 neurologically healthy young (mean age 21.8), middle-aged (mean age 51.7), and elderly (mean age 73.1) adults, were examined using procedures by Nippold, Schwarz, and Undlin (1992). Groups were matched for education level. The results indicate a significant decline in processing adverbial conjuncts in the elderly. Discordant adverbial conjuncts especially challenged the linguistic processing abilities of the elderly subjects. The age- related decline in processing adverbial conjuncts.appears to be a specific deficit in linguistic processing that is independent of problems in memory or the effects of exposure to sophisticated language forms.
