Early identification of dyslexia: Evidence from a follow-up study of speech-language impaired children

A group of speech-language impaired children was administered a battery of standardized language tests and measures of phonological processing in kindergarten. Performance on these language measures was then compared to reading ability in first grade. Results indicated that children with semantic-syntactic language deficits had more difficulties in reading than did children with primarily speech articulation impairments. In addition, phonological processing measures were found to be good predictors of reading achievement. Results are discussed in terms of their implications for the early identification of developmental dyslexia. This research was supported by a grant from the Department of Education (HO24U8001).     

Morpho-lexical development in language impaired and typically developing Hebrew-speaking children from two SES backgrounds

The study investigated the impact of language impairment and environmental deprivation on Hebrew morpho-lexical development across the school years. Participants were 659 grade school and middle school Hebrew-speaking students—typically developing and language impaired, from mid-high and from low socio-economic status (SES). They were all administered three derivational morphology tasks designed to elicit verbs, adjectives and derived abstract nouns. Each response was scored in three different ways: as a whole word, and according to its base (root or stem) and affixal (pattern or suffix) morphemes. Findings revealed three systematic hierarchies. First, the typically developing mid-high SES group always scored the highest, the language impaired low SES group always scored the lowest, while the typically developing low SES and the language impaired mid-high SES groups lay in-between. Second, verbs were the easiest category across all study groups, whilst adjectives and derived abstract nouns proved to be more affected by population type. Third, affixal morpheme always scored lower than base morpheme, with persistent gaps between the typically developing mid-high SES group and all other groups. Altogether, results show that language development is impeded extensively by both language impairment and SES factors, suggesting that in the long run, innate and environmental factors may have similar implications on morpho-lexical development.     

Occurrence and pattern of impaired reading and written language in children with attention deficit disorders

The purpose of this study was to investigate the occurrence and severity of reading, spelling, and written language impairment in children clinically referred for Attention Deficit Hyperactivity Disorder (ADHD). Specific questions involved 1) whether ADD subgroups with and without hyperactivity differ in reading, spelling, and written language achievement, 2) whether age and gender interact with ADD sub-group class to affect reading/written language achievement, and 3) whether prevalence of impaired reading/written language in these subgroups is consistent with previous reports in heterogeneous samples. Subjects were 115 ADD children aged 6-12 who were subclassified as ADD + H(72 percent) and ADD - H(28 percent) by objective teacher ratings. Dependent measures included tests of single word recognition and vocabulary, word attack, contextual comprehension, written spelling, written sentence construction, and writing fluency, in addition to a structured behavioral observation, during which aspects of inattention and motor activity were coded. A large fraction of this sample met public school LD criteria (54 percent), and achievement on most measures was globally poorer than the respective test normative groups. The ADD + H subgroup showed significantly poorer word attack skills, while the subgroups did not significantly differ from each other on other reading/written language measures. However, 17 percent of the total ADD sample were ≥ 1.5 SD below the mean in total reading achievement, and 29 percent were ≥ 1.5 SD below the mean on measures of written spelling/language. Gender X age interactions, indicating poorer performance in the middle age group of females, were likely related to lower IQ.     

The effects of multisensory structured language instruction on native language and foreign language aptitude skills of at-risk high school foreign language learners: A replication and follow-up study

According to research findings, most students who experience foreign language learning problems are thought to have overt or subtle native language learning difficulties, primarily with phonological processing. A recent study by the authors showed that when a multisensory structured language approach to teaching Spanish was used with a group of at-risk high school students, the group’s pre- and posttest scores on native language phonological processing, verbal memory and vocabulary, and foreign language aptitude measures significantly improved. In this replication and follow-up study, the authors compared pre- and posttest scores of a second group of students (Cohort 2) who received MSL instruction in Spanish on native language and foreign language aptitude measures. They also followed students from the first study (Cohort 1) over a second year of foreign language instruction. Findings showed that the second cohort made significant gains on three native language phonological measures and a test of foreign language aptitude. Follow-up testing on the first cohort showed that the group maintained its initial gains on all native language and foreign language aptitude measures. Implications for the authors’ Linguistic Coding Deficit Hypothesis are discussed and linked with current reading research, in particular the concepts of the assumption of specificity and modularity.     

A small-scale pilot study into language difficulties in children who offend

This small-scale pilot research project investigates the prevalence of Speech Language and Communication Difficulties in a sample of children attending a Youth Offending Service in the UK. Using the CELF-4, approximately 90% of the sample displayed some form of language difficulty and, overall, this population displayed mild to moderate difficulties in this area. Youth Offending Team staff questionnaires were also analysed and it was found that staff have little understanding of the difficulties presented by the children on their caseloads, despite reporting that they felt confident in this area. Implications for practice and potential roles for educational psychologists are discussed.     

Families with abused children: A follow-up study of post-crisis support

Treatment provisions planned and executed were studied in a follow-up of 14 abused or neglected children three years after discharge from the Children's Department of Ullevaal Hospital. A majority of the families were shown to have received either no help or inappropriate help. Half of the children were evaluated as being so emotionally impaired that serious future adjustment problems could be anticipated. Inappropriate treatment related to lack of understanding, workers' own feelings and normative standards. Overidentification with parents and a general belief in their ability to develop caring skills were observed as was the tendency to overlook or minimize the child's experiences and the risk to which he was exposed. Anxiety, insecurity and lack of skill in establishing appropriate relationships prevented workers obtaining adequate bases for evaluation and for effectuation of treatment. Workers' professional situations were unfavorable in specified ways. Appropriate treatment was based on differentiated psychosocial evaluation, a high involvement level by the worker and continuity. The professional situation was also favorable. Workers combined traditional therapeutic approaches with conscious use of professional authority. They intervened actively for protective purposes but were empathetic with both child and parents.     

Battered children grown up: a follow-up study of individuals severely maltreated as children.

Despite intensive research interest, the field of child abuse has produced few long-term follow-up studies. This paper describes the adult functioning of a group of 19 individuals who were severely battered as young children. Results indicate highly variable outcomes for the group: Some individuals exhibited limited autonomy and few adult coping skills while others were raising families, holding jobs, and maintaining functional social ties. There was little evidence of overt aggression in the group but resentment and suspiciousness scores were high. Many subjects maintained ties with their troubled parents while others sought out birth parents after losing contact with them in childhood. Several had developed long-term stable marriages, and social supports appeared adequate for most subjects in the group. Overall, study findings indicate that early abusive trauma and adult functioning have no simple relationship.     

Egocentric language in deaf children

Egocentric language is a generalization of Piaget's egocentric speech concept (1926/1969) investigated by Vygotsky (1962). Behaviors of eight children ages 2 to 5 years with profound congenital deafness were analyzed using six classes of egocentric language: motor reaction activity, silent lips articulation, murmur, oral-facial mimics, body expression, and vocalization. No child had received oral or sign language training. All attended videotaped play sessions. Events in which children engaged in "dialogue" with themselves or a toy, while pursuing a specific solution, were observed. Such extralinguistic behavior moves the thinking process toward problem solving like that of hearing children. Consequently, teachers should not interrupt when a deaf child is playing with or signing or vocalizing to a toy, because this behavior may be the manifestation of a reflexive moment and the generator of a decision process fundamental for cognitive development. Vocalization by a deaf child does not indicate willingness to speak; it merely manifests symbolic reasoning. Silent lips articulation and oral-facial mimics have the same effect and can also be interpreted.

Neurobiological aspects of language in children

This article discusses the relevance of the study of the neurobiology of cognitive development, both for an understanding of the neural bases of cognition and of the nature of cognition itself. A key issue is the age at which hemisphere specialization first appears and whether it changes over time. The neuropsychological literature concerning language in both normal and brain-damaged children is reviewed. The usefulness of studying cognition in other clinical disorders and variation in normal cognition is indicated. The various methods used in the research are described and the methodological and interpretational difficulties arising from the diversity of groups studied and the methods used are discussed. The model is advanced that hemisphere specialization exists from birth onward and does not undergo further change in either its nature or degree. The apparent increase in the extent of hemisphere specialization during childhood is interpreted as an epiphenomenon of the increasing cognitive and behavioral repertoire of the child. Neural plasticity, assumed to underlie recovery of function, is seen as being coexistent with, but independent of, hemisphere specialization.     

How children learn to use language

There have been many theories about how children learn to use language. Professor Narasimhan proposed a theory of child language acquisition based on behavioural pragmatics. In this article we present a simplified version of his theories about how children learn to communicate, to describe, manipulate and explore the world around them from exposure to variety of language utterances and non-verbal inputs such as gestures and pointing. We also discuss the method he used to substantiate his ideas, and briefly present a computational model of the ideas arising from his work. Raman Chandrasekar has been with Microsoft Research, Redmond, USA. since 1998. His current research interests are at the intersection of information retrieval, natural language processing and machine learning. He received his PhD from TIFR, Bombay.
