In honor of Dr. Katherine Butler's extraordinary leadership of Topics in Language Disorders, this article takes up her 1982 challenge to reach toward greater understanding of individual differences in the use of oral and written language by children with language learning disability. The article focuses on 3 interconnected dimensions of learning that appear important for the eventual resolution of Dr. Butler's challenge: (1) the stability vs the instability of language-learning profiles, (2) the unique pathways that learning may take, and (3) linear vs nonlinear perspectives of language learning. Future directions are then outlined for rethinking individual variations in language learning disability. [ABSTRACT FROM AUTHOR]

Several investigations have considered the spelling abilities of children with reading disability; however, the spelling patterns of children with a language learning disability (LLD) have been largely ignored. This study examined the spelling error patterns of three groups of children who met strict inclusion criteria-those with a known LLD (n = 8), chronological-age-matched peers (CA; n = 8), and a younger spelling-age-matched group (SA; n = 8). An experimental spelling measure was specially designed and administered to elucidate the underlying linguistic features (clusters, digraphs, etc.) and linguistic classifications (phonological, orthographical, morphological) of misspellings. Based on inferential statistical analyses, a general pattern was that the LLD group and the SA group always differed from the CA group, whereas the LLD group performed similarly to the SA group. This finding lends credence to the hypothesis that children with an LLD, like children with reading disability, are delayed in spelling development rather than following a deviant developmental process. However, a qualitative analysis indicated two specific patterns. First, the LLD group had more trouble than did the SA group in representing the basic phonological structure of words, when complexity was increased by word length or linguistic structure. Second, in contrast to the SA group, the LLD group had greater omissions of inflected and derived morphological markers. These findings point to the critical role of morphology as the mediator between and form and meaning. [ABSTRACT FROM AUTHOR]

The case description provides a comprehensive picture of the complex social and linguistic factors that shape the social identity of an English language learner with the additional challenge of language impairment (LI). These issues were explored over 6 months with Fernando, an 8-year-old, Spanish-speaking male with LI in grade 3. A pragmatic, or practical, approach to problem solving was developed for two purposes: first, to obtain a multifaceted understanding of Fernando's world at school, and second, to arrive at possible educational/clinical solutions that met a standard of cultural appropriateness and practicality. The patterns found that, contrary to teacher interpretations of Fernando as inattentive, he employed both perseverance and saving face strategies, which appeared to function as practices for preserving his self-esteem in different situations. These patterns led to specific recommendations for collaborative instruction and intervention that would better integrate and support Fernando's social and bilingual learning needs while also meeting standards of cultural appropriateness and practicality.

Purpose: A hallmark of autistic spectrum disorder (ASD) is disruption in theory-of-mind development, including the understanding of false beliefs. Previous studies have typically assessed the development of first- and second-order false belief concepts in ASD, with tasks primarily emphasizing physical causality and logical inferencing. The present study investigated how preadolescents and adolescents with ASD performed on false belief tasks that included social inferencing of psychological states as well as logical inferencing of physical states.Method: Two categories of tasks were administered: four traditional logical inferencing tasks and four social inferencing tasks specifically developed for this study. In addition, a prompt hierarchy was included to ascertain if performance on both task types improved. Participants were 45 children and adolescents primarily selected from three urban school districts: 15 adolescents with a previous diagnosis of ASD (ASD group); 15 typically developing children matched for age, gender, and ethnicity (CA group); and 15 typically developing children matched for language age, gender, and ethnicity (LA group).Results: Three findings were pertinent. First, the CA group performed at higher levels than did the LA group and the ASD group on both task sets. Second, although the CA and the LA groups performed equally well on both the logical and the social inferencing tasks, the ASD group performed better on the social inferencing tasks. Finally, the prompt hierarchy significantly improved overall task performance for the ASD and LA groups.Clinical Implications: These findings indicate that task type, variations in vocabulary ability, and the provision of support influenced performance on the false belief tasks.

Speech-language pathologists have not typically included writing as part of instructional or intervention goals. This omission may be related to the sparse research data on writing development in children with a language learning disability (LLD). Like reading and spelling, writing results from complex interactions among the linguistic and discourse systems and changes over time from an oral style of communication to a more literate style. One purpose of this article is to describe individual differences in the phases of writing development, drawing on examples from students who are typically developing, and those with an LLD. Special emphasis is given to the differentiation of audience and syntactic choices during the school-age years as critical elements in communicating the 'writer's voice.' Using an illustrative case study of a 10-year-old, the second purpose is to demonstrate how school-based writing samples can serve as a dynamic tool for analysis of interactions among the linguistic and discourse systems. The multiple levels addressed include genre knowledge, concept of audience, clausal and nonclausal complexity, spelling, and punctuation. A major assessment issue is whether the writing problems of individual students stem from an unrecognized LLD, instructional inadequacies, or both factors. Suggestions are offered for better meeting individual needs through combining explicit strategy instruction for composing and self-regulation with explicit linguistic strategies that enhance semantic and syntactic options in writing.

Purpose: This article describes a study on the scaffolding of learning to read in a primary-level, continuous-progress, inclusion classroom that stressed a critical thinking curriculum and employed a collaborative teaching model. Two emergent reading groups were the focus of study--one group that was taught by a general educator and the other by a special educator. The primary purposes were to discern the teachers' discourse patterns in order to define whether scaffolding sequences were more directive or more supportive and the degree to which these sequences represented differentiated instruction for children with a language learning disability (LLD). Method: Two students with an LLD and two younger, typically developing peers were videotaped in their emergent reading groups during an 8-week period. The distribution, types, and functions of teacher scaffolding sequences were examined. Results: Both team members primarily used directive scaffolding sequences, suggesting that the assistance provided to children emphasized only direct instruction (skill learning) and not analytical thinking concerning phoneme-grapheme relationships (strategy learning). Distribution of scaffolding sequence types directed to the four students indicated that the two children with an LLD were receiving reading instruction that was undifferentiated from the two typically developing, younger children. Clinical Implications: In order for children with an LLD to benefit from inclusion, explicit, systematic, and intensive instruction in phonological awareness and spelling-sound relationships should be implemented within the context of multilevel instruction that balances skill- and strategy-based learning.

The purpose of inclusion for children with language-learning disabilities (LLD) is to provide integrated educational opportunities within the general education classroom. Inclusion and practices related to inclusion require collaboration among regular educators, special educators, speech-language pathologists, and families. This article distinguishes between full inclusion and optional inclusion, reviews studies on the outcomes of inclusion, describes a university-school partnership model for educational restructuring, and outlines six reasons why innovative changes, such as inclusion and integrated learning, are often difficult to sustain. This background frames the experiences of an educational team with a continuous progress, inclusion model for students with a LLD. The team consists of a regular educator, a speech-language pathologist, and a teacher of specific learning disabilities. Their story demonstrates the importance of flexibility in adapting inclusion models and the necessity for maintaining classroom partnerships for uniting research with practice.

Purpose Morphology, which is a bridge between phonology and orthography, plays an important role in the development of word-specific spellings. This study, which employed longitudinal sampling of typically developing students in Grades 3, 4, and 5, explored how the misspellings of words with derivational suffixes shed light on the interplay of phonological, orthographic, and morphological (POM) linguistic features as students learn to integrate POM features appropriately to generate correct spellings. Method Sixty typically developing Grade 3 students were tested using the Spelling subtest from the Wechsler Individual Achievement Test-Second Edition (Wechsler, 2001) and were divided into superior, average, and poor spellers. Students' spelling skill was then assessed using the Wechsler Individual Achievement Test-Second Edition annually for another 2 years. Misspelled derivations from these three testing sessions were analyzed for linguistic feature errors and error complexity/severity. Differences in the integration of POM features across spelling ability levels at Grades 3-5 were analyzed with Kruskal-Wallis analyses of variance. Results Longitudinal results demonstrated POM integration for the development of word-specific spellings involving derivational morphology was in its initial stages over Grades 3-5 and was influenced by spelling ability level. Information from a qualitative analysis revealed considerable variability in how students applied their POM knowledge to spell complex derivations. Conclusions Word-specific spellings draw on multiple linguistic codes-P, O, and M-and their interconnections. It involves more than an understanding of orthographic rules. Rather, accurate spelling develops through an increased understanding of the phoneme-grapheme relationships as facilitated by the identification of word parts (base + or - affixes) in written language. Educational and clinical implications are discussed.

Bailey and Ferreira (2003) hypothesized and reported behavioral evidence that disfluencies (filled and silent pauses) undesirably affect sentence processing when they appear before disambiguating verbs in Garden Path (GP) sentences. Disfluencies here cause the parser to "linger" on, and apparently accept as correct, an erroneous parse. Critically, the revision process usually associated with GP-disambiguating verbs does not appear to be triggered. In order to verify this effect, we recorded event-related potentials (ERPs) time-locked to disambiguating verbs in spoken GP sentences from 15 adults. A filled pause, silent pause, or no disfluency appeared before the GP-disambiguating verbs. Principal component analysis (PCA) revealed that fluent GP sentences elicited P600, an ERP index that revision of the initial parse was attempted. Crucially, P600 was attenuated for sentences containing a filled or silent pause before the GP-disambiguating verb. However, PCA detected an N400-like activation for these items, suggesting that listeners accepted the original (erroneous) parse and continued integrating at the verb; a conclusion that is tentative and requires further study. A left anterior positivity was also detected at GP-disambiguating verbs flanked by a filled pause. Discussion focuses on what these preliminary findings tell us about how oral comprehension proceeds when the time-course of sentence processing is disrupted.

Purpose: This study examined how complexity of maternal epistemological beliefs predicted mothers' and children's talk about the mind., Method: Twenty-eight mothers of 5- to 10-year-olds completed a measure of receptive vocabulary, and mothers and children participated in a storytelling task specifically designed to elicit talk about the mind. Their use of mental state terms to encode pragmatic functions and mothers' epistemologies were assessed and compared., Results: Maternal mental state talk and amount of talk increased with epistemological complexity. With the number of utterances held constant, mothers with simple, dualistic perspectives of knowledge used mental states more often to direct interaction; mothers with more complex epistemologies used mental states more often to encourage child reflection. Mothers with the less complex perspective underperformed on the receptive vocabulary measure in comparison to others. Children's amount of talk and use of a variety of mental state terms also increased with maternal epistemological complexity. The amount of talk and mental state terms produced by mothers and children frequently persisted after the effects of maternal receptive vocabulary were removed., Conclusions: Maternal epistemologies predict several qualities of mothers' and children's mental state talk that may contribute to children's developing theory of mind.

Purpose: To evaluate the role of dialect on phonemic awareness and nonword spelling tasks. These tasks were selected for their reliance on phonological and orthographic processing, which may be influenced by dialect use., Method: Eighty typically developing African American children in Grades 1 and 3 were first screened for dialect use and then completed a standardized test of phonological processing and a nonword spelling measure. The influence of dialect was analyzed in both experimental tasks, followed by a qualitative analysis of dialect use in nonword spellings., Results: Dialect density measures based solely on the use of African American English (AAE) phonological features explained few differences in phonological processing scores. In contrast, correlations indicated that children with higher dialect densities produced more nonword spelling errors influenced by AAE, an effect most evident in Grade 3. Qualitative analyses revealed AAE phonological features occurring in many of the misspelled nonwords., Conclusion: After Grade 2, nonword spelling may be more sensitive to the effects of dialect variation than are phonemic awareness tasks. It is suggested that spelling may be a more sensitive clinical indicator of difficulties in integrating the phonological and orthographic information needed for fluent decoding skill.

Anomia is a commonly found in aphasia and has been attributed to a loss of representations (storage deficit) or to a loss of access to these representations (retrieval deficit). Bromocriptine, a dopamine agonist, was tested on four patients, two men and two women, with nonfluent aphasia. The patients were tested in an open-label ABBA design using a stochastic model that measured the degree of storage and retrieval deficits. All patients showed significant improvements in word retrieval. Bromocriptine may be a useful adjunct in the treatment of selected patients with a nonfluent aphasia in which retrieval deficits play a major role., (Copyright 2000 Academic Press.)

This is a partial replication of Brooks, Braine, Catalano, Brody, and Sudhalter (1993). 32 participants learned a miniature linguistic system (MLS). Vocabulary of the MLS consisted of an actor subject, two sets of 19 object nouns, and two sets of three suffixes. In the experimental language, 60% of the nouns were phonologically marked with a common ending for each class; in the control, these endings were distributed across the classes. Participants were trained using pictures. Sentences about the pictures combined the actor's name with an object and an appropriate suffix that described the actor-object relation. A subset of possible sentences and objects was reserved for later testing. During generalization tests, participants had to produce sentences for pictures they had not seen during training. The experimental group was markedly superior to the control. The replication supports the earlier finding that learning of seemingly arbitrary linguistic classes can be facilitated by partial phonological cues.

Oral precursors underlying competence with literacy activities are approached through a review of studies on narrative comprehension and production in children identified as language learning disabled (LLD). Areas addressed include a general overview of narrative types, the kinds of narrative knowledge that are acquired, the nature of story organization, and developmental acquisitions in story recall and generation. Nine studies on the oral comprehension and production of language learning disabled children are then compared with respect to methodological issues and patterns of performance. Implications from these studies are discussed in terms of their potential insight for subtypes of a LLD including the value of oral narratives in identifying precursors for competence with written language.

Effects on spatial term comprehension as the result of transformations in the stimulus dimensions of six pictures containing the same three figures were explored using Piaget's concept of spatial perspective. A Modified Test of Pictorial Space (MTPS), adapted from Hudson's (1960) studies on non-Western pictorial perception strategies, was administered to 200 children, aged 6 yrs 5 mos to 11 yrs 3 mos. The purpose of the investigation was to gather data on (1) pictorial interpretation as a function of variations in perceptual depth cue complexity and transformations in conceptual perspective and (2) order of acquisition in the comprehension of two sets of spatial terms referring to perceptual object knowledge and more advanced conceptual knowledge of object relations. Significant age and IQ, but not sex, interactions were found for MTPS performance. Data analyses also supported predicted orders of acquisition and indicated that transformation of conceptual perspective better differentiated among the age span than did either perceptual depth cue complexity or comprehension of spatial terms. Findings are discussed in terms of their methodological and substantive implications for constructing and interpreting pictorially-based language comprehension tasks.
