Purpose The purpose of our study was to test the hypotheses (a) that children with dyslexia have spoken word learning deficits primarily related to phonology and (b) that children with dyslexia and concomitant developmental language disorder (DLD) have word learning deficits related to both phonology and semantic processing when compared to peers with typical development (TD). Method Second-graders with dyslexia ( n = 82), concomitant dyslexia and DLD (dyslexia + DLD; n = 40), and TD ( n = 167) learned names and semantic features for cartoon monsters in 5 carefully controlled word learning tasks that varied phonological and semantic demands. The computer-based tasks were played in 6 different word learning games. We analyzed results using Bayesian statistics. Results In general, the dyslexia + DLD group showed lower accuracy on tasks compared to the dyslexia and TD groups. As predicted, word learning tasks that taxed phonology revealed deficits in the dyslexia group, although there were some exceptions related to visual complexity. Word learning deficits in the dyslexia + DLD group were present in tasks that taxed phonology, semantic processing, or both. Conclusions The dyslexia + DLD group demonstrated word learning deficits across the range of word learning tasks that tapped phonology and semantic processing, whereas the dyslexia group primarily struggled with the phonological aspects of word learning.

Purpose Learning novel words, including the specific phonemes that make up word forms, is a struggle for many individuals with developmental language disorder (DLD). Building robust representations of words includes encoding during periods of input and consolidation between periods of input. The primary purpose of the current study is to determine differences between children with DLD and with typical development (TD) in the encoding and consolidation of word forms during the slow mapping process. Method Preschool-age children (DLD = 9, TD = 9) were trained on nine form–referent pairs across multiple consecutive training days. Children's ability to name referents at the end of training days indicated their ability to encode forms. Children's ability to name referents at the beginning of training days after a period of overnight sleep indicated their ability to consolidate forms. Word learning was assessed 1 month after training to determine long-term retention of forms. Results Throughout training, children with DLD produced fewer forms correctly and produced forms with less phonological precision than children with TD. Thus, children with DLD demonstrated impaired encoding. However, children with and without DLD demonstrated a similar ability to consolidate forms between training days and to retain forms across a 1-month delay. Conclusions Difficulties with word form learning are primarily driven by deficits in encoding for children with DLD. Clinicians and educators can support encoding by providing children with adequate exposures to target words via robust training that occurs across multiple sessions.

Report Measure

We explore the classification accuracy of a parent and teacher report measure, the Inventory to Assess Language Knowledge (ITALK), to screen for developmental language disorder (DLD) in bilingual children. Participants included 120 Spanish English bilingual children with typical development (TD) and 19 bilingual children with DLD, ranging in age from 5 to 8 years old. Parents’ and teachers’ reports correlated moderately with each other and significantly predicted children’s performance on language-specific measures of morphosyntax and semantics. Results yielded sensitivity of .90 and specificity of .63 when using a composite of parent and teacher reports in Spanish and English. Examination of structure loadings in follow-up analyses by grade showed that teachers’ report of English and parents’ report of Spanish were the strongest predictors of impairment in kindergarten. In second grade, the strongest predictors were parent and teacher reports in English. Implications for referral and identification are discussed.

Mapping Condition

Purpose The aim of the study was to determine the integrity of fast mapping among adults with developmental language disorder (DLD). Method Forty-eight adults with DLD or typical language development (TD) were presented with 24 novel words and photos of their unfamiliar referents from the semantic categories of mammal, bird, fruit, or insect in two conditions. In the fast-mapping condition, 12 of the 24 unfamiliar referents were presented, one at a time alongside a familiar referent (e.g., a dog) and a question (e.g., Is the tail of the torato up? ). In the explicit-encoding condition, the other 12 unfamiliar referents were presented alone, one at a time, with a label (e.g., This is a spimer ). Immediately after exposure (T1) and again after a 1-day interval (T2), memory for the word-to-exemplar link was measured with a three-alternative forced-choice test, requiring the participant to match a spoken word to one of three pictured referents from the training set. At T2, memory for semantic category information was measured with a four-alternative forced-choice test, requiring the participant to match a spoken word to one of four prototypical silhouettes representing each of the semantic categories. Results Performance on word-to-exemplar link recognition was stronger for words learned in the explicit-encoding than the fast-mapping condition and stronger for the TD group than the DLD group. Time was not a significant factor as both groups maintained posttraining levels of performance after a 1-day retention interval. Performance on semantic category recognition was stronger for words learned in the explicit-encoding than the fast-mapping condition and stronger for the TD group than the DLD group. The lower category recognition performance of the DLD group was related to their lower nonverbal IQ scores. Conclusion Contexts that allow for explicit encoding yield better learning of word-to-referent links than contexts that allow for fast mapping in both stronger and weaker learners. Adults with DLD have difficulty learning the link between words and referents, whether trained via fast mapping or explicit encoding and whether tested with exemplar or category referents. Retention is a relative strength for adults with DLD. Supplemental Material https://doi.org/10.23641/asha.12765551

Purpose The goal was to determine whether interactive book reading outcomes for children with developmental language disorder (DLD) were affected by manipulation of dose (i.e., the number of exposures to the target word during a book reading session) and dose frequency (i.e., the number of repeated book reading sessions) and whether pretreatment factors predicted treatment response variation. Method Thirty-four kindergarten children with DLD (aged 5;0–6;2 [years;months]) were taught 1 set of words using the Dose 6 and Dose Frequency 6 format from a prior study ( Storkel, Voelmle, et al., 2017 ) and taught a different set of words using an alternative format, either Dose 4 × Dose Frequency 9 or Dose 9 × Dose Frequency 4, determined through random assignment. Word learning was tracked for each treatment via a definition task prior to, during, and after treatment. Results Results showed that children with DLD learned a significant number of words during treatment regardless of the dose and dose frequency format but that significant forgetting of newly learned words occurred in all formats once treatment was withdrawn. Individual differences in word learning were related to Clinical Evaluation of Language Fundamentals Core Language and Understanding Spoken Paragraphs scores. Conclusion When administered at an adequate intensity, variation in the dose and dose frequency of interactive book reading does not appear to influence word learning by children with DLD. Although interactive book reading continues to show promise as an effective word learning intervention for children with DLD, further development is needed to enhance the effectiveness of this treatment approach.

Verbal Tasks

Purpose Current research has demonstrated that behavioral, emotional, and/or social difficulties often accompany developmental language disorder (DLD). It is an open question to what degrees such difficulties arise as consequence of impaired language and communicative skills, or whether they might also be driven by deficits in verbal and nonverbal emotion processing (e.g., the reduced ability to infer and verbalize emotional states from facial expressions). Regarding the existence of nonverbal deficits, previous research has yielded inconsistent findings. This study was aimed at gaining deeper knowledge of the basic aspects of emotion understanding in children with DLD by comparing their performance on nonverbal and verbal emotion categorization tasks to that of typically developing children. Method Two verbal tasks (Lexical Decision and Valence Decision With Emotion Terms) and two nonverbal tasks (Face Decision and Valence Decision With Facial Expressions) were designed to parallel each other as much as possible, and conducted with twenty-six 6- to 10-year-old children diagnosed with DLD. The same number of typically developed children, carefully matched by age and gender, served as a control group. Results The children with DLD showed lower performance in both verbal tasks and exhibited noticeable problems in the nonverbal emotion processing task. In particular, they achieved lower accuracy scores when they categorized faces by their valence (positive or negative), but did not differ in their ability to distinguish these faces from pictures displaying animals. Conclusions This study provides evidence for the hypothesis that problems in emotion processing in children with DLD might be multimodal. Therefore, the results support the idea of mutual influences in the development of language and emotion skills and contribute to the current debate about the domain specificity of DLD (formerly referred to as specific language impairment).

Purpose Developmental language disorder (DLD), an unexplained problem using and understanding spoken language, has been hypothesized to have an underlying auditory processing component. Auditory feedback plays a key role in speech motor control. The current study examined whether auditory feedback is used to regulate speech production in a similar way by children with DLD and their typically developing (TD) peers. Method Participants aged 6–11 years completed tasks measuring hearing, language, first formant (F1) discrimination thresholds, partial vowel space, and responses to altered auditory feedback with F1 perturbation. Results Children with DLD tended to compensate more than TD children for the positive F1 manipulation and compensated less than TD children in the negative shift condition. Conclusion Our findings suggest that children with DLD make atypical use of auditory feedback.

(1) Background: Developmental Language Disorder (DLD) is diagnosed when the child experiences problems in language with no known underlying biomedical condition and the information required for its correct evaluation must be obtained from different contexts. The Children’s Communication Checklist (CCC-2) covers aspects of a child’s communication related to structural language and pragmatic skills, which are linked to social cognition or executive functions. The aim of this article is to examine parents’ reports using the Spanish version of the CCC-2 questionnaire and its association with different formal assessments related to communication. (2) Methods: 30 children with DLD (3; 10–9 years old) and 39 age-matched (AM) children with typical development were assessed using formal measures of structural language, pragmatics, social cognition, and executive functions. Parents of children with DLD answered the Spanish version of the CCC-2. (3) Results: The performance of children with DLD was lower in all the formal assessments in comparison to AM children. The CCC-2 was significantly correlated with all the direct child assessments, although only formal measures of structural language predicted both the structural language and pragmatics scales of the CCC-2. (4) Conclusions: The CCC-2 answered by parents was consistent with formal assessments in children with DLD, and structural language seemed to be the best predictor of all the subscales.
