Preconditions of language development in deaf children.

The harmful effects of childhood hearing impairment are given little thought by many people because hearing loss is largely an invisible handicap. An infant with a hearing impairment is generally healthy-looking and develops relatively normally during the first year of life. Hearing impairment in infants interferes with the normal development of spoken language. We are biologically programmed to develop certain skills in response to certain inputs. Language learning is one such skill which must be gained very early in life. Hearing is the most important basis for normal language acquisition and language is the keystone of modern society. Hearing loss must be identified as early as possible in the first years of life, especially a child with profound or severe hearing loss must be identified in the first year of life. If not, the child has missed an irreversible sensitive phase for learning of speech and language.

Expressive language development of children exposed to cocaine prenatally: literature review and report of a prospective cohort study.

It was hypothesized that prenatal exposure to cocaine and other substances would be related to delayed expressive language development. Speech and language data were available for 458 6-year olds (204 were exposed to cocaine). No significant univariate or multivariate differences by cocaine exposure group were observed. Classification and regression tree modeling was then used to identify language variable composites predictive of cocaine exposure status. Meaningful cut points for two language measures were identified and validated. Children with a type token ratio of less than 0.42 and with fewer than 97 word types were classified into a low language group. Low language children (n = 57) were more likely to be cocaine exposed (63.1%), with cocaine-exposed children 2.4 times more likely to be in the low language group compared with control children after adjustment for covariates. Prenatal cigarette, but not alcohol exposure, was also significantly related to expressive language delays.

Clinical interest of brainstem auditory evoked potentials in 72 children with inadequate language development.

The present study is of brainstem auditory evoked potentials (BAEP) in 72 children, of 2 to 13 years of age, showing inadequate language development. The age of the children was mainly below the age of 4 (39 cases = 54%), peaking between 3 and 4 years of age (33 cases = 46%). Even so, 82% of our patients were 3 years old or over: 64% were boys, 36% girls, the proportion of boys falling off with age 26% (19 cases) of BAEPs recorded were normal, 74% (53 cases) pathological. High prevalence of undiagnosed hearing loss was found. Physiopathological BAEP classification showed endocochlear impairment in 68% (36 cases), conductive impairment in 21% (11 cases) and retrocochlear impairment in 11% (6 cases) of subjects. Unilateral impairment (20 cases = 28%) cannot account for inadequate language development; but, in the 8 cases (11%) of total bilateral hearing loss, and the 15 cases (21%) of partial bilateral impairment, hearing loss more or equal to 50 dB HL, impaired hearing would play a role in the retardation.

Preschool language development among children of adolescent mothers.

This longitudinal study examined a comprehensive set of predictors of preschool language performance in a sample of children of adolescent mothers. Six domains of risk (low maternal verbal ability, intergenerational risk, contextual risk, relational risk, home environmental risk, and child characteristics) for poor preschool language development, measured throughout early childhood, were examined in a sample of 154 children born to adolescent mothers. Logistic regression revealed that having a poor language-learning home environment was associated with children's low language scores even after accounting for mothers' below-average verbal ability. More importantly, however, was the exploration of the 'dual risk' hypothesis that evaluated the effects of combined risk factors. Being reared by a mother with low verbal ability amplified the risk of a poor quality home linguistic environment, whereas having a poor home linguistic environment did not adversely affect the language development of children with mothers of average verbal ability. Implications for intervention are discussed with regard to specificity of intervention efforts within subpopulations of risk identified in this paper.

A prospective evaluation of early language development in children with in utero cocaine exposure and in control subjects.

A cohort of children of low socioeconomic status, 76 with in utero cocaine exposure and 81 control subjects, was assessed for early language development at 2 1/2 years of age by a masked examiner using the Preschool Language Scale. There were no differences between groups in expressive, receptive, or total language score (all p > or = 0.57). Physicians caring for cocaine-exposed children with early language delay should not automatically ascribe the delay to cocaine exposure but should initiate a standard evaluation for language delay.

Language development of very low birth weight infants and fullterm controls at 12 months of age.

Twenty-eight very low birth weight (VLBW) and 32 full term infants were prospectively assessed at one year of age for hearing, language development and neurological status. The prevalence of conductive hearing deficits was the same in both groups. Language scores in VLBW infants were significantly lower than in fullterm controls and 39% had significant language delays. VLBW infants exhibited a shorter attention span and were less likely to understand simple questions, to recognize objects or body parts when named, to initiate speech-gesture games, to follow simple commands and to imitate or use words consistently. Language quotients were directly associated with gestational age and five minute Apgar scores and inversely associated with severity of intraventricular hemorrhage, bronchopulmonary dysplasia and length of hospital stay. VLBW small for gestational age infants exhibited more advanced language skills than VLBW appropriate for gestational age infants. Language delays were more prevalent among, but not limited to, infants with mild to moderate neurological abnormalities. The influence of prematurity and VLBW on language development is complex and multifactorial and research is continuing to determine the predictive validity and long term significance of the early language delays described in this study.

[Initial examination for school attendance in Mannheim: language development at initial school entry level].

INTRODUCTION: In autumn 2001 the initial examination for school attendance in Mannheim has been fundamentally reorganised. The individual examination elements had been widely standardized, the results can be evaluated by regions and a diagnosis for the early detection of legasthenia has been developed. METHODS: The testing involved repeating sentences, numbers and artificial words. This has been developed by the Pedagogical University Heidelberg. In pre-examinations in Heidelberg the results relate significantly to the subsequent results in reading and writing. PROBANDS: A total of 2,744 children (46.1% girls, 53.9% boys) aged of 5 to 7 years was seen. 71.5% of the children were German nationality. Most non-German nationalities were Turkish (15.4%) and Italian (3.6%) children. Besides the nationality the mother tongue has been also recorded. More than 96% of the children had been attending a kindergarten. For judgement of the social strata the frequency of social welfare receivers has been recorded. RESULTS: The testing results are significantly influenced by the native language and the social strata of the children. The results of children with German as native language are above those of non-Germans. Within the migrant children there are significant differences between the several nationalities. Children from a lower social strata achieved lower results. A positive effect to the language development is attributed to the attendance of a kindergarten. CONCLUSION: These results are the basis for language- and general health supporting projects in Mannheim. For the examination for school attendance in the current year the diagnostic for language development has been extended by some more aspects.

Low-level lead exposure in the prenatal and early preschool periods: language development.

Inconsistent results continue to be reported from studies linking low-level lead exposure and child development. This inconsistency is seen for both prenatal exposure and exposure in the preschool years. The primary outcome measures in most reports are indices of cognitive development, including IQ. Verbal skills may be particularly vulnerable to toxic insult. The fact that 2 y of age is both a time of peak exposure and also a time of rapid language development suggests that this may be a critical period for such an effect. The later prenatal and early infancy period, at which time the nervous system is developing rapidly, may also be critical exposure period. We examined the relationship of maternal and cord blood lead (PbB) at birth and venous PbB at 6 mo, 2 y, and 3 y with language measures at 1, 2, and 3 y of age. The sample consisted of disadvantaged urban children. Multivariate analyses revealed no statistically significant relationship of either prenatal PbB or early preschool PbB with language measures after control of cofactors. Supplementary partial correlations revealed a marginal relationship of cord PbB and mean length of utterance (MLU), which describes a child's ability to form meaningful word combinations. Because this analysis was one of a large number of analyses with both positive and negative regression coefficients, the possibility that this was a chance effect was considered. If there is an effect of low-level lead exposure on language development, that effect is not robust.

The implications of childhood bacterial meningitis for language development.

Bacterial meningitis is a life threatening infection of the central nervous system. This illness is most prevalent early in life when the healthy child is rapidly acquiring language. This study investigated whether children with a history of bacterial meningitis were at risk for language difficulties post illness. Thirty post-meningitic children, aged between 9 years 0 months and 11 years 0 months, participated in this study. Each subject was administered a measure of non-verbal cognitive ability and a range of language tasks. These children performed poorly on applied language tasks, which tap skills used in effective discourse. These deficits occurred despite age appropriate performances on measures of linguistic/grammatical knowledge. These findings clearly illustrate that bacterial meningitis has implications for ongoing language development, which emphasises the importance of long term follow up. In developmental terms, this discrepancy between verbal knowledge and problem solving represents a dissociation between language skills which develop early in life and those which emerge later. This pattern of results suggests that bacterial meningitis may result in a delay in language development. A young age at illness was identified as an additional risk factor for adverse outcome. This study highlights the need to inform parents/guardians that post-meningitic children are at risk for experiencing language difficulties throughout childhood.

The acquisition of Italian morphology: implications for models of language development [see comment].

This study explores the spontaneous acquisition of Italian inflectional morphology by three children (age range I;4-3;O). Longitudinal, free speech samples are examined, focusing on the development of the morphological paradigms of Italian verbs, pronouns and articles. Data analysis is conducted using criteria appropriate to allow reliable cross-linguistic comparisons with data from English. By this means we evaluate the plausibility of a nativist, parameter-setting account of language development in Italian and English, as recently proposed for these two languages. Results show that the general developmental patterns observed in Italian are not significantly different from those found in English. These findings are not consistent with current interpretations of parameter-setting accounts of language development. Alternative explanatory models are discussed.

Language development and emotional expression.

The relation of language and emotion in development is most often thought about in terms of how language describes emotional experiences with words that name different feelings. However, children typically do not begin to use these words until language development is well underway, at approximately 2 years of age. Given the relatively small number of words for naming feelings and emotions, and the redundancy between emotion words and the expressions they name, understanding how emotion and language are related in early development requires looking beyond just acquisition of specific emotion words.

[Haptic perception and language development assessment in kindergarten and pre-school children].

In a study with 101 children aged 3 to 5 years expressive vocabulary, morpho-syntactical language skills, and tactile-kinesthetic/haptic perception (stereognosis of object properties, object stereognosis) were assessed. Substantial correlations were found between tactile-kinesthetic/haptic perception and the selected language facets. Age differences in expressive language skills remained significant even when tactile-kinesthetic/haptic perception was partialized out. On the contrary, age differences in tactile-kinesthetic/haptic perception were partially eliminated when language skills were controlled for. The results are discussed with regard to the role of the tactile-kinesthetic/haptic senses in language development.

Speech perception in infancy predicts language development in the second year of life: a longitudinal study.

Infants' early phonetic perception is hypothesized to play an important role in language development. Previous studies have not assessed this potential link in the first 2 years of life. In this study, speech discrimination was measured in 6-month-old infants using a conditioned head-turn task. At 13, 16, and 24 months of age, language development was assessed in these same children using the MacArthur Communicative Development Inventory. Results demonstrated significant correlations between speech perception at 6 months of age and later language (word understanding, word production, phrase understanding). The finding that speech perception performance at 6 months predicts language at 2 years supports the idea that phonetic perception may play an important role in language acquisition.

Relative treatment effects of two prelinguistic communication interventions on language development in toddlers with developmental delays vary by maternal characteristics.

This paper tests whether two prelinguistic communication interventions have a differential effect on productive and receptive language development 6 and 12 months after the end of treatment. We predicted that treatment effects on language development would vary as a function of pretreatment maternal responsivity or amount of mothers' formal education. Fifty-eight prelinguistic children with developmental delays and their mothers participated in the study. Children were randomly assigned to one of two staff-implemented treatments that were designed to increase intentional communication ability. Results confirmed the prediction that treatment effects on children's receptive and expressive language 6 and 12 months after the end of interventions vary as a function of pretreatment maternal responsivity and education level.

Developmental progression in play behavior of children between nine and thirty months: II: Spontaneous play and language development.

The relationship between play behavior displayed in a structured play situation and language development was studied cross-sectionally in 85 children at eight age--evels between nine and 30 months. There were no correlations between types of play behavior, in particular functional play (appropriate use of objects on the child's own body), representational play (appropriate use of objects on a doll or another person), or symbolic play (substitution of present objects for absent ones) and speech measures such as total number of words and of vocalizations, number of different words and different vocalizations, and number of sentences. Identification of objects upon verbal request was not related to any type of play behavior, but comprehension of verbal requests for functional or representational play was postively correlated with the display of functional or representational play. The children did not respond to verbal requests for functional or representational play unless these types of play behavior were part of their spontaneous play repertoire. Understanding of prepositions seemed to be related to spatial concepts expressed in play behavior, such as container play or arranging chairs around a table and setting the table.

Metaphoric competence in cognitive and language development.

Consideration of the age-related changes in children's language and cognitive development suggests qualitative changes in their creative language use. Many, if not most, researchers in the area have argued that some metaphoric competence emerges far earlier than would be expected on the basis of explanation or interpretation tasks alone. These same researchers, however, appear largely to have neglected consideration of the cognitive prerequisites for such abilities and differences between what is nonliteral for the adult and nonliteral for the child. If figurative language is defined as involving intentional violation of conceptual boundaries in order to highlight some correspondence, one must be sure that children credited with that competence have (1) the metacognitive and metalinguistic abilities to understand at least some of the implications of such language (Lakoff & Johnson, 1980; Nelson, 1974; Nelson & Nelson, 1978), (2) a conceptual organization that entails the purportedly violated conceptual boundaries (Lange, 1978), and (3) some notion of metaphoric tension as well as ground. Having stacked the definitional cards, we doubt that many investigators would assert that 2-year-old children at nonverbal symbolic play are doing anything that is literally metaphorical in our terms. But neither will we deny that one can observe creative components in the verbal and nonverbal play of the young child that are precursors of later nonliteral language skills (see McCune-Nicolich, 1981, for discussion). We simply do not see these creative abilities as specific to language in any way that justifies calling them metaphoric competence. Rather, the child's abilities to deal flexibly with the world, to "play" with possible alternative organizations of it, and to see similarity in diversity represent the bases of subsequent cognitive as well as language development. Far from being an exceptional aspect of development, apparently nonliteral language should be considered a fundamental tool in the young child's construction of both internal and external worlds (McCune-Nicolich, 1981; Vygotsky, 1978). If one is willing to accept that children's conceptual organization might not match that of adults, then what is appropriately called nonliteral language in the young child must be reexamined. We find it strange that researchers acknowledge differences, for example, in children's notions of animacy, and yet assume that errors of animacy attribution are figurative constructions indicative of an ability to supercede a level of analysis the child does not have.(ABSTRACT TRUNCATED AT 400 WORDS)
