To verify the mean length of silent pauses in narratives and the influence of the complexity of stories on the production of such pauses in the narratives of children with DLD and with TLD and compare both groups. |
60 children aged 7 to 10 years - 20 with DLD and 40 with TLD. 15 increasingly complex stories were used to record the mean length of pauses produced in narratives. |
Children with DLD made longer silent pauses in their narratives, regardless of story type than those with typically developing children. Longer pauses demonstrate fragile linguistic processing. |

To verify the conflict-solving skills of children with SLI and the correlation between the time of SLH therapy and their performance in conflict-solving tasks. |
20 children with SLI and 40 with TLD, aged 7 years to 8 years and 11 months. |
Children with DLD have greater difficulty solving conflicts, predominantly using physical and unilateral strategies, which are insufficient to solve many conflicts. No correlation was found between the time of therapy and performance in the conflict-solving task. |

To investigate whether the parts of speech influence the mean length of silent pauses during narrative production by children with DLD and with TLD. |
20 children with DLD and 40 with TLD, aged 7 to 10 years. The analysis approached the children’s narratives, the nouns, adjectives, verbs, conjunctions, prepositions, and pronouns they used, and the pauses that preceded these elements. |
Silent pauses were shorter when they preceded nouns and longer when they preceded conjunctions in both groups. The analysis demonstrated that the group with DLD made longer silent pauses in all parts of speech. |

To compare disrupted speech in narrative production in students with DLD and their chronological peers. |
60 children aged 7 to 10 years - 20 with DLD and 40 with TLD. Data collection used 15 stories represented by figures with four scenes each. The stories were transcribed, and speech disruptions were classified into various types. |
Students with DLD have more stuttering and nonstuttering disruptions than their peers. Nonstuttering disruptions (interjections, reviewing/abandoning segments, and repeating sentences or multisyllables) were the most frequent in the DLD group. These disruptions are more associated with linguistic planning than speech-motor control. |

To assess speech fluency regarding the types of disruptions and speech speed in children with suspected DLD. |
50 children of both sexes, aged 3 to 7 years, without stuttering, divided into 2 groups: G1- 25 children with suspected DLD (diagnosis not confirmed, yet); G2- children with TLD. |
Children aged 3 to 4 years with suspected DLD spoke slower than the typically developing ones, with no difference regarding the types of disruptions. No difference was found between the groups in the 5-to-7-year age range. |

To explore the effects of the school type and DLD on different language skills from the quantitative and qualitative perspectives. |
204 Brazilian children aged 4 to 6 years divided into 3 groups: TDpriv, TDPub, and DLDpub. All children were assessed regarding expressive vocabulary, number morphology, and morphosyntactic comprehension skills. |
Children with DLD performed worse in language skills than typically developing ones from both public and private schools. They mistook nominal number morphology and morphosyntactic comprehension. As they grew older, they moved to a systematic error pattern, suggesting they have not only a developmental delay but also idiosyncratic patterns. |

To verify the functional use of verbs and nouns by children with SLD, comparing it between them and children with TLD. |
80 preschoolers - 20 with SLD, aged 3 to 6 years, and 60 with TLD, aged 2 to 4 years. |
Children with SLD use verbs more than nouns in their productions, in comparison with children with TLD. Intransitive, linking, and direct transitive verbs were used more often, and children had difficulties using verbal arguments - they omitted verb objects, indicating difficulties with grammar structures. |

To identify and compare the performance of children with DLD and with TLD in alliteration and rhyme identification tasks and verify the influence of semantic and phonological distractors. |
12 students with DLD and 48 with TLD, aged 7 years to 9 years and 11 months, submitted to rhyme and alliteration identification tasks. |
Both groups performed worse in rhyme than in alliteration. Students with DLD performed worse than those with TLD in both tasks (alliteration and rhyme). Children with DLD also used more semantic distractors in alliteration tasks and more phonological distractors in rhyme tasks. |
