Processamento linguístico e processamento auditivo temporal em crianças com distúrbio específico de linguagem

BACKGROUND: several studies suggest the association of specific language impairment (SLI) to deficits in auditory processing.It has been evidenced that children with SLI present deficit in brief stimuli discrimination. Such deficit would lead to difficulties in developing phonological abilities necessary to map phonemes and to effectively and automatically code and decode words and sentences. However, the correlation between temporal processing (TP) and specific deficits in language disorders - such as syntactic comprehension abilities - has received little or no attention. AIM: to analyze the correlation between: TP (through the Frequency Pattern Test - FPT) and Syntactic Complexity Comprehension (through a Sentence Comprehension Task). METHOD: Sixteen children with typical language development (8;9 ± 1;1 years) and seven children with SLI (8;1 ± 1;2 years) participated on the study. RESULTS: Accuracy of both groups decreased with the increase on syntactic complexity (both p < 0.01). On the between groups comparison, performance difference on the Test of Syntactic Complexity Comprehension (TSCC) was statistically significant (p = 0.02).As expected, children with SLI presented FPT performance outside reference values. On the SLI group, correlations between TSCC and FPT were positive and higher for high syntactic complexity (r = 0.97) than for low syntactic complexity (r = 0.51). CONCLUSION: Results suggest that FPT is positively correlated to syntactic complexity comprehension abilities.The low performance on FPT could serve as an additional indicator of deficits in complex linguistic processing. Future studies should consider, besides the increase of the sample, longitudinal studies that investigate the effect of frequency pattern auditory training on performance in high syntactic complexity comprehension tasks.

Crianças com implante coclear: habilidades comunicativas e qualidade de vida

UNLABELLED Given the multidimensional scope of cochlear implants, there is a growing need to assess clinical measures related communicative abilities and more general aspects involved in the effectiveness of treatment, such as quality of life. AIM To translate and adapt an international questionnaire of quality of life to Brazilian Portuguese; to apply the questionnaire in parents of children with cochlear implant to assess quality of life of children after cochlear implantation; to analyze correlations among factors related to quality of life; to analyze correlations between quality of life and clinical measures of outcome. METHOD Prospective study in which parents of children with cochlear implants responded to validated instruments on quality of life and communication abilities. RESULTS The translation and adaptation of the questionnaire was satisfactorily completed. According to the data, cochlear implants had a positive effect on quality of life of the implanted children and their families. Observed correlations for the variable communication demonstrate a direct relationship between oral communication and other variables of quality of life. CONCLUSIONS This study makes this questionnaire available in Brazilian Portuguese. For parents of Brazilian children with cochlear implants, lexical development(acquisition and use of words) is the variable that relates most to the quality of life of their children.

Aspectos da fluência da fala em crianças com distúrbio específico de linguagem

Purpose The present study aimed to assess specific aspects of speech fluency in children with specific language impairment (SLI). This included examining the typology of speech disruption and rate (in words and syllables per minute), across different age groups. Methods A total of 50 children, aged 3 to 7 years old, presenting with nonverbal IQ and hearing thresholds within normal limits (without the presence of stuttering) participated in the study. Children were divided into two groups: G1 (SLI) included 25 children (7 girls and 18 boys) and G2 (typical development) included 25 children matched on age and gender with G1. Each child was shown a figure and asked to discuss what s/he liked about the figure. Each speech sample included 200 fluent syllables or 100 fluent words. Results Between-group analyses demonstrated that children aged 3 to 4 years old in G1 had lower speech rate than their age-matched peers from G2. Within-group analyses revealed no differences in disruption typologies between age groups in G1 participants. In contrast, hesitation was the most frequent typology for 4- to 5-year-old G2 children, whereas hesitation and word repetition typologies were observed in 6- to 7-year-old G2 children. Conclusion Children with suspected SLI between the ages of 3 to 4 years old showed a reduction in word and syllable production. Hesitation-type speech disruptions were prominently used by typically developing children, regardless of age, and were not observed in SLI children.

Priming lexical em crianças fluentes e com gagueira do desenvolvimento

PURPOSE To examine the possible relationship between lexical variables (categorization and naming) and developmental stuttering. METHODS Thirty Brazilian Portuguese speaking children with ages ranging from 7 to 9 years and 11 months participated in the study. We applied a lexical priming paradigm to experimentally investigate whether children with developmental stuttering (Research Group) differed from their fluent peers (Control Group), with respect to reaction time in three conditions - control (without prime); semantically related prime, and semantically independent prime - of two experimental tasks: categorization and naming of the target stimulus. RESULTS No difference between groups was observed in reaction time on the categorization task. However, there was a condition effect showing that, for both groups, reaction time was shorter in the semantically related prime condition when compared to the no prime condition. In the naming task, a between-group difference was observed in reaction time, indicating a longer reaction time in the Research Group than the Control Group. There was no condition effect on naming, i.e. the Research Group showed slower reaction time regardless of prime type. CONCLUSIONS The results confirm the hypothesis that, in children with developmental stuttering, readiness in motor programming of speech is slowed when compared to fluent children. There is no difference between groups when the lexical function does not require speech readiness.

Deglutição e consistências alimentares pastosas e sólidas: revisão crítica de literatura

ABSTRACT Purpose: To analyze published international scientific papers on the physiology of deglutition in oral and pharyngeal phases, consi-dering different food consistencies: nectar, honey, pudding, pasty heterogeneous, semi-solid, and solid. Methods: This is a qualitative literature reviews. The studies considered were selected on PubMed, using the keywords “Swallowing and consistency”, “Swallowing and solid”, and “Swallowing and pasty”, limiting the search to manuscripts published in English in the period between 2005 and 2010, and conducted with human beings over 18 years old. The methodology involved question formulation, location and selection of studies, and critical analyses of the manuscripts, according to the concepts of the Cochrane Handbook. Results: Two hundred and eleven studies were identified, out of which only 18 allowed access to the full text and were directly related to the theme. Conclusion: The studies presented very few similarities between the applied methodologies, especially when considering assessment methods. Overall, the studies were conducted with healthy individuals or with a specific pathology, without presenting the comparison with control cases. The heterogeneity of studies allows the investigation of different swallowing disorders. However, methodological variability makes it difficult to define and generalize the identified swallowing patterns. For this reason, it is not possible to identify parameters on which to base the clinical practice of speech-language therapists, especially when considering the normal or altered physiology of swallowing different food consistencies.
