“…The first language-based processing task to gain traction as an identifier of DLD is nonword repetition. This task has been shown to separate children with DLD from unaffected peers in speakers of General American English (Graf Estes, Evans, & Else-Quest, 2007), African American English (Rodekohr & Haynes, 2001), and a variety of languages other than English (e.g., Dispaldro, Leonard, & Deevy, 2013;Kapalková, Polišenská, & Vicenová, 2013;Pham, Ebert, Dinh, & Dam, 2018;Thordardottir & Brandeker, 2013). Sentence repetition has also received increasing attention as a language-based processing task with the ability to identify DLD.…”

Purpose Accurate identification of developmental language disorder (DLD) remains challenging, particularly for children who speak different dialects, languages, or more than 1 language. Children with DLD, on average, have shown subtle deficits on nonlinguistic cognitive processing tasks, and performance on such tasks may be minimally influenced by language experience. This study explores whether nonlinguistic cognitive processing tasks can contribute to the identification of DLD in children from diverse linguistic backgrounds. Method Study 1 combined data from 4 U.S.-based investigations to yield a sample of 395 children, ages 6–10 years, who spoke only English or both Spanish and English. Study 2 consisted of an international sample of 55 kindergarten children living in Vietnam. Each study included children with DLD and children with typical development. Participants completed nonlinguistic cognitive tasks of processing speed, auditory working memory, and attentional control. Data analysis compared typically developing to DLD groups by age and language background. Then, we empirically derived cut-points to report diagnostic accuracy (sensitivity, specificity, and positive and negative likelihood ratios). Results For all 3 tasks, adequate sensitivity or specificity (but not both in most cases) was achieved in nearly all age groups. Likelihood ratios reached moderately to very informative levels in several instances. Diagnostic results were maintained when monolingual and bilingual samples were combined into a single group. Conclusions Nonlinguistic cognitive processing tasks may contribute to accurate identification of DLD in combination with other measures. Further research is needed to refine tasks, confirm cut-points established here, and extend findings to children from additional language backgrounds.

“…On the other hand, signed stimuli that exhibited sequential complexity on a par with disyllabic spoken words were reproduced with reduced accuracy. This is in contrast to spoken pseudoword tasks, in which children generally begin to show a breakdown in accuracy only once the word length reaches three or more syllables ( Thal et al, 2005 ; Gathercole, 2006 ; Pham et al, 2018 , a.o). In the following subsections we discuss each of these results in turn.…”

“…Older children perform better than younger children, and shorter items are produced with higher accuracy than longer items (Chiat, 2006). This length effect has been found in English (Gathercole et al, 1994;Weismer et al, 2000;Thal et al, 2005), and other languages such as Brazilian Portuguese (Santos et al, 2006), Spanish (Ebert et al, 2008), Korean (Lee et al, 2013), Swedish (Sundström et al, 2014), French (dos Santos andFerré, 2018), and Vietnamese (Pham et al, 2018). While some studies only include words of two or more syllables, others have found that when one-syllable words are included in the stimuli, such as the NRT, which consists of one-to four-syllable pseudowords in English, one-syllable and two-syllable words were produced with a similar accuracy level, with accuracy dropping only from three syllables upward by typically developing children (Gathercole et al, 1994;Weismer et al, 2000;Thal et al, 2005).…”

In this study, we conducted a pseudosign (nonce sign) repetition task with 22 children (mean age: 6;04) acquiring American Sign Language (ASL) as a first language (L1) from deaf parents. Thirty-nine pseudosigns with varying complexity were developed and organized into eight categories depending on number of hands, number of simultaneous movement types, and number of movement sequences. Pseudosigns also varied in handshape complexity. The children’s performance on the ASL pseudosign task improved with age, displaying relatively accurate (re)production of location and orientation, but much less accurate handshape and movement, a finding in line with real sign productions for both L1 and L2 signers. Handshapes with higher complexity were correlated with lower accuracy in the handshape parameter. We found main effects of sequential and simultaneous movement combinations on overall performance. Items with no movement sequence were produced with higher overall accuracy than those with a movement sequence. Items with two simultaneous movement types or a single movement type were produced with higher overall accuracy than those with three simultaneous movement types. Finally, number of hands did not affect the overall accuracy. Remarkably, movement sequences impose processing constraints on signing children whereas complex hands (two hands) and two simultaneous movement types do not significantly lower accuracy, indicating a capacity for processing multiple simultaneous components in signs. Spoken languages, in contrast, manifest greater complexity in temporal length. Hearing children’s pseudoword repetition still displays high levels of accuracy on disyllabic words, with complexity effects affecting only longer multisyllabic words. We conclude that the pseudosign repetition task is an informative tool for studies of signing children’s phonological development and that sheds light on potential modality effects for phonological development.

“…Although cross-linguistic exploration from non-words repetition had doubled recently, most studies solely focused on European languages (Marinis & Armon-Lotem, 2015). Some Asian languages had begun to be researched, such as Cantonese (Stokes et al, 2006) and Vietnamese (Pham et al, 2018;Pham & Ebert, 2020). Indonesian should also be considered for an examination, for it provided distinct linguistic characteristics, which did not exist in European languages.…”

This study examined the potential of using word and non-word repetition to screen children with speech delay in Indonesia. The tasks adapted Dollaghan & Campbell (1998), which was adjusted to Indonesian. There were 32 items arranged in two sets, consisting of 16 words and 16 non-words, and four items in one, two, three, and four syllables. The sets were counterbalanced across participants. The total number of phonemes in each set was 96. This research involved two children with speech delay (aged 5;0 (year;month) coded B12, and aged 7;1 coded A12); and eleven typically developing children as a control group for each of A12 and B12. The accuracy of word repetitions of all number of syllables by B12 revealed significantly lower results than the accuracy of the control group. The accuracy of non-word repetition in this group did not show any significant differences. For the group of participants aged 7 years, the word repetition revealed significant differences, although A12 had performed normally in two-syllable words. In this group, the repetition of 3- and 4-syllables non-words by participant A12 showed significantly lower results compared to the accuracy of the control group. Clinical and developmental implications in the Indonesian context were discussed.KEYWORDS: Speech Delay, Non-word Repetition, Word Repetition, Language Disorders in Children
