Language Development Disorders*

OBJECTIVE: To investigate the relationship of language, intelligent and social quotients in children with speech and language disorder and to evaluate the clinical usefulness of language quotient for predicting the extents of cognitive and social functions. METHOD: Total 139 children who visited the department of rehabilitation medicine for the evaluation of suspected speech-language delay. All children were evaluated for receptive and expressive language quotients, articulation accuracy, verbal, performance and full-scale intelligent quotients and social maturation assessment. RESULTS: Approximately 70% of the children who had chief complaints of speech or language disorder were diagnosed as 'receptive and expressive language developmental delay'. Intelligent and social quotients of the children with receptive and expressive language developmental delay were significantly lower than those of the other groups (p<0.05). Both receptive and expressive language quotients, but not dysarticulation, were significantly correlated with intelligent and social quotients (p<0.05). Multiple regression analysis demonstrated that the language quotients could predict intelligent and social quotients as simple equations (p<0.01). CONCLUSION: Primary result of receptive and expressive language quotients from screening test of language evaluation might be able to predict cognitive function and social maturity, which also showed high-degree positive correlation with intelligent and social quotients. This result could provide a useful guideline for further developmental studies in children with speech and language disorder who received primary speech evaluation.

PURPOSE:The purposes of this paper are to analyse the degree of language delay according to the classification and the etiology of mental retardation and to assess the efficacy of language treatment in children who received language treatment. METHODS:The number of the subjects for the research is 79. The subjects had been diagnosed as children of mental retardation after a language development test from the language treatment center of the Chungnam National University Hospital from January, 2003 to December, 2007. We gathered the data concerning their main complaints, their etiology of mental retardation, their results of a language development test and an intelligence test, and their results of language treatment. RESULTS:The results of our analysis to the data are as follows: The distribution of mental retardation classified as mild, moderate, and severe is 51.9% of the subjects, 27.9% and 20.2% each. The etiology of mental retardation is distributed as postnatal(20.3%), prenatal(13.9%), prenatal(5.1%), and idiopathic(60.7%). According to the classification of mental retardation, receptive, expressive, and synthetic language show a significant difference. There is no significant difference in the etiology of mental retardation in statistics. Among 28 children taken a language test after language treatment, 14 mild mental retarded children made their language delay to be shortened by 19.9 months, 10 moderate mental retarded children made their language delay to be shortened by 7.2 months, and 4 severe mental retarded children reduced their language delay by 1.3 month. CONCLUSION:The more severe mental retardation is, the longer language delay occurred. But there is no significant difference to language delay according to the etiology of mental retardation. After language treatment, mild mental retarded children show the remarkable shortening of language delay, while moderate and severe mental retarded children are slightly shortening. Therefore, it is thought that more active language treatment is needed to mild mental retarded children.

OBJECTIVE: To evaluate correlations between values of articulation tests and language tests for children with articulation disorder in Korea. METHODS: Data of outpatients with chief complaint of an articulation problem were retrospectively collected. Patients who underwent Urimal Test of Articulation and Phonation (U-TAP) with Assessment of Phonology and Articulation for Children (APAC), Preschool Receptive-Expressive Language Scale (PRES), or Receptive and Expressive Vocabulary Test (REVT) simultaneously were identified. Patients whose word-level percentages of correct consonants in U-TAP (UTAP_wC) were more than 2 standard deviations below the mean as diagnostic criteria for articulation disorder were selected. Those whose receptive language age (P_RLA), expressive language age (P_ELA), or combined language age (P_CLA) in PRES was delayed more than 24 months compared to their chronological age in months as diagnostic criteria for language disorder were excluded. RESULTS: Thirty-three children aged 3–6 years were enrolled retrospectively. PRES and U-TAP showed significant correlations for most of value relationships. PRES and APAC showed significant correlations for all value relationships except for receptive language age. All values of REVT were significantly correlated with all values from U-TAP, but not with any value from APAC. Articulation tests U-TAP and APAC showed significant correlations between percentages of correct consonants. Language tests PRES and REVT showed significant correlations for all value relationships. CONCLUSION: This study suggests that articulation abilities and language abilities might be correlated in children with articulation disorder.

OBJECTIVETo explore the phonological characteristics and rehabilitation training of abnormal velar in patients with functional articulation disorders (FAD).

METHODSEighty-seven patients with FAD were observed of the phonological characteristics of velar. Seventy-two patients with abnormal velar accepted speech training. The correlation and simple linear regression analysis were carried out on abnormal velar articulation and age.

RESULTSThe articulation disorder of /g/ mainly showed replacement by /d/, /b/ or omission. /k/ mainly showed replacement by /d/, /t/, /g/, /p/, /b/. /h/ mainly showed replacement by /g/, /f/, /p/, /b/ or omission. The common erroneous articulation forms of /g/, /k/, /h/ were fronting of tongue and replacement by bilabial consonants. When velar combined with vowels contained /a/ and /e/, the main error was fronting of tongue. When velar combined with vowels contained /u/, the errors trended to be replacement by bilabial consonants. After 3 to 10 times of speech training, the number of erroneous words decreased to (6.24±2.61) from (40.28±6.08) before the speech training was established, the difference was statistically significant (Z=-7.379, P=0.000). The number of erroneous words was negatively correlated with age (r=-0.691, P=0.000). The result of simple linear regression analysis showed that the determination coefficient was 0.472.

CONCLUSIONSThe articulation disorder of velar mainly shows replacement, varies with the vowels. The targeted rehabilitation training hereby established is significantly effective. Age plays an important role in the outcome of velar.

PURPOSE: The objective of this study was to test the predictive validity of developmental test for later intellectual development in young children with delayed language development. METHODS: The study subjects were 66 children who had presented delayed language development and had an initial developmental test and a follow-up intelligence test. The mean age at initial test was 34.2 months(17-48 months), and the mean age at the follow-up test was 55.0 months(40-79.5 months). RESULTS: According to CAT DQ(Cognitive Adaptive Test Developmental Quotient), 66 children were divided into 4 groups: group I(CAT DQ<50), group II(50-69), group III(70-84), and group IV(> = or85). There was a moderate correlation between CAT DQ and later total IQ in group I(r=0.58) and II(r= 0.50), but a low correlation in group III(r=0.19) and IV(r=-0.16). IQs in follow-up tests of all children in group I and II were lower than 70, except two children whose IQs were 75 and 78. IQs of children in group III were lower than 85 except for three children whose IQs were 89, 89, and 90, respectively. CONCLUSION: The findings of this study suggest that if DQ is lower than 70, the child is highly probable to be mentally subnormal in later years. Although the correlation between CAT DQ and later total IQ is low in children with DQs over 70, if a DQ is between 70 and 84, the child is very likely to have learning disability in later years.

OBJECTIVE: To analyze speech and linguistic features in children with articulation disorder characterized by consonant and vowel phonological errors. METHODS: Between February 2007 and June 2015, 117 children who showed articulation disorder were selected for the study. Based on comprehensive speech and language assessments, the subjects were classified into articulation dysfunction (AD), or AD overlapping with language delay. Detailed information of articulation, including percentage of consonants correct (PCC) and normal percentage of variable consonants derived from the Assessment of Phonology and Articulation for Children test, were compared between the two groups. RESULTS: Totally, 55 children were diagnosed as AD and 62 as AD with language delay. Mean PCC was not significantly different between the two groups. In both groups, the acquisition order of consonants followed the universal developmental sequence. However, differences were observed in the nasal & plosive consonants abnormality between the two groups. When adjusted to their delayed language level in AD with language delay group, 53% of children had appropriate articulation function for their expressive language level. CONCLUSION: Speech and linguistic characteristics in children with articulation disorder were variable. Therefore, comprehensive assessment is required in children with inaccurate pronunciation, and a proper treatment plan based on the results of assessment should be followed.

PURPOSE: High-functioning autism spectrum disorder (ASD) involves pragmatic impairment of language skills. Among numerous tasks for assessing pragmatic linguistic skills, idioms are important to evaluating high-functioning ASD. Nevertheless, no assessment tool has been developed with specific consideration of Korean culture. Therefore, we designed the Korean Autism Social Language Task (KASLAT) to test idiom comprehension in ASD. The aim of the current study was to introduce this novel psychological tool and evaluate idiom comprehension deficits in high-functioning ASD. MATERIALS AND METHODS: The participants included 42 children, ages 6-11 years, who visited our child psychiatric clinic between April 2014 and May 2015. The ASD group comprised 16 children; the attention deficit hyperactivity disorder (ADHD) group consisted of 16 children. An additional 10 normal control children who had not been diagnosed with either disorder participated in this study. Idiom comprehension ability was assessed in these three groups using the KASLAT. RESULTS: Both ASD and ADHD groups had significantly lower scores on the matched and mismatched tasks, compared to the normal control children (matched tasks mean score: ASD 11.56, ADHD 11.56, normal control 14.30; mismatched tasks mean score: ASD 6.50, ADHD 4.31, normal control 11.30). However, no significant differences were found in scores of KASLAT between the ADHD and ASD groups. CONCLUSION: These findings suggest that children with ASD exhibit greater impairment in idiom comprehension, compared to normal control children. The KASLAT may be useful in evaluating idiom comprehension ability.
