Developmental Science

Background Early intervention for children identified as late talkers (LTs) at the age of 24 months is still a controversial issue in research and clinical routine. Previous studies have shown inconsistent results regarding predictors of early lexical deficits on school‐age outcomes of late‐talking toddlers. Methods In a five‐wave follow‐up study we investigated various aspects of language and literacy abilities in 39 German‐speaking third‐graders who had been identified as late talkers (LTs) at the age of 24 months, compared to 39 typically developing children (TDC) also attending the third grade. The duration of auditory sensory memory was examined at the age of four years using mismatch negativity (MMN) of tones – an event‐related potential not confounded by any language skill. In addition, the predictive value of memory performance was examined in a longitudinal perspective. Results Overall, LTs scored within normal range in language and literacy assessments. However, LTs differed from TDC in vocabulary size, verbalization of semantic relations, non‐word repetition and spelling. The findings can be explained by phonological working memory. The duration of auditory sensory memory and spatial working memory did not account for any variance. Conclusions LTs sustain persistent phonological processing limitations even though their native language and literacy performance lay within the normal range at school‐age. Further research on second language acquisition, academic achievements and the efficacy of early intervention in late‐talking toddlers is recommended. This article is protected by copyright.

Background: 30-50% of late talkers catch-up their language delay during the third year of life. So far it is unclear whether this is a permanent or an illusionary recovery. The aim of the study was to examine the further language development of late bloomers. Method: Language skills of 83 three-year-old children (16 late bloomers [LB], 29 late talkers [LT] with persistent language problems, 38 Non-LT) were assessed with a standardized language test. Before school entry formal language skills, expressive and receptive vocabulary and precursors of written language (verbal memory, phonological awareness, verbal information-processing speed) were assessed. Results: At follow-up before school entry LB scored below Non-LT on phonological memory test. 31% of the LB in contrast to 3% of the Non-LT had slight language problems. 38% had received speech-language therapy. Nevertheless, no LB met the criteria of developmental language disorder. The language skills of LT with persistent language problems remained significantly below the level of LB and Non-LT. Every fourth of these children was language impaired. Conclusion: LB as a group are not at risk for later clinically relevant language disorders. However, their language abilities are often within the lower range of normal variation. Therefore, it is recommended to facilitate their language acquisition either by kindergarten training programs or by parent-directed intervention programs to provide a more stimulating environment. © Georg Thieme Verlag KG Stuttgart · New York.

Hintergrund Die klinische Relevanz eines verspäteten Sprechbeginns ist umstritten. Ziel der Arbeit In der vorliegenden Studie wurde untersucht, wie bei einsprachig deutsch aufwachsenden Spätsprechern („late talkers“, LT) die sprachliche Entwicklung bis ins mittlere Kindergartenalter verläuft und wie häufig mit persistierenden Sprachauffälligkeiten zu rechnen ist. Material und Methode In einer Längsschnittstudie wurden die sprachlichen Leistungen von 46 LT und 40 Nichtspätsprechern („non-late talkers“, NLT) im Alter von 4½ Jahren erneut untersucht. Grammatische und semantische Fähigkeiten wurden mit standardisierten Tests und mithilfe einer Spontansprachanalyse beurteilt. Außerdem wurden die Lautbildungsfähigkeit und die Vorläuferfertigkeiten für den Schriftspracherwerb überprüft. Ergebnisse Mit 4½ Jahren lagen die Leistungen der LT auf allen Sprachebenen signifikant unter denen der NLT. Es hatten 43 % der LT Sprach- und 41 % Lautbildungsauffälligkeiten. Von den LT waren 37 % logopädisch behandelt worden. Auch unter den NLT waren einzelne Kinder sprachauffällig. Schlussfolgerung Die Ergebnisse sprechen dafür, dass ein verzögerter Sprechbeginn ein Hinweis auf schwache Sprachkompetenzen und ein Zeichen eines Risikos für persistierende Sprachauffälligkeiten ist. Spätsprecher sollten deshalb frühzeitig erfasst und gefördert werden. Da aber über die Hälfte der LT keine anhaltenden Sprachauffälligkeiten zeigen, sind kostenintensive Interventionen in den meisten Fällen nicht gerechtfertigt. Empfehlenswert ist unter Berücksichtigung von Effektivität und Kosten-Nutzen-Verhältnis die systematische Anleitung der Eltern zu sprachförderndem Verhalten in Kleingruppen.

Zusammenfassung Für ein Sprachscreening haben sich in den ersten Lebensjahren Elternfragebögen bewährt. Mit diesen kann der augenblickliche Sprachentwicklungsstand eines Kindes recht gut beurteilt werden. Aufgrund der großen Variabilität des frühen Spracherwerbs sind aber in den ersten 1½ Lebensjahren eine Vorhersage des weiteren Sprachverlaufs und eine Früherkennung sprachgestörter Kinder nicht möglich. Erst am Ende des zweiten Lebensjahres lassen sich Kinder mit einem erhöhten Risiko für Sprachentwicklungsstörungen erfassen. Eine ausreichend sichere Identifizierung sprachentwicklungsgestörter Kinder gelingt nicht vor dem Ende des dritten Lebensjahres. Ein spezifisches Sprachscreening sollte ab der U7 durchgeführt werden. Zur Früherkennung von Risikokindern bei der U7 eignet sich insbesondere der SBE-2-KT und für die U7a der SBE-3-KT. Beide Elternfragebögen sind normiert und standardisiert und die diagnostische Zuverlässigkeit bei der Identifizierung sprachauffälliger Kinder wurde belegt. Bei einem positiven Screeningbefund ist in einem zweiten Schritt eine weitere Diagnostik zur Abklärung der Art und Ausprägung der Sprachprobleme erforderlich.

Late talkers (LTs) show very different courses of language development. The aim of this study was to examine whether subgrouping LTs in terms of language comprehension could allow the identification of specific subtypes with different prognoses. Amongst other assessment strategies, standardized language (SETK-2, SETK 3-5), general nonverbal development (MFED, SON-R 2½-7) and hearing tests (TOAE) were used to examine 48 LTs at the ages of 25 and 37 months. Deficits in language comprehension were recorded for 38 % of the LTs. LTs with and without impaired language comprehension differed only slightly in terms of their further language and nonverbal development, as well as in terms of anamnestic data. Comprehension of words but not of sentences proved to be a predictor of later speech impairments. Classification of LTs based on the comprehension of single words, but not of sentences or general language comprehension, at the age of 25 months can define subgroups of children with different prognoses. However, this only leads to marginal improvements in the predicted development of LTs, since substantial impairment of word comprehension is rarely observed.

... In addition to language problems, DLD may have long-term (neuro)psychological sequelae, including long-lasting learning problems and negative psychosocial outcomes (Conti-Ramsden et al., 2012;Snowling et al., 2006). Importantly, even LTs who ended up not having a diagnosis of DLD show linguistic performances significantly lower than those of controls without language delay as far as in late adolescence (Grossheinrich et al., 2019;Rescorla, 2009;Rice et al., 2008). As highlighted in recent international and national consensus conferences (Bishop et al., 2016;Sansavini, Favilla, et al., 2021), early identification of those children with an enhanced probability of experiencing persistent language disorder is crucial but still challenging. ...

... In contrast to the results found by Escera and Grau (1996), in our data the replicability of the N1 amplitudes was also much higher in the deviant responses than the individual stability of the MMN tudes. Source analyses of the ERPs of this study (Albrecht et al., 1998) showed very stable results for the N1 as well and a low stability for the MMN sources. The somewhat lower reliability of the deviant responses as compared to the standards is probably due to the fact that for these waveforms a lower number of sweeps were averaged resulting in a lower SNR. ...

... During the last decade, research on developmental dyslexia has accumulated, and yet the theories about mechanisms underlying this deficit are still controversial (Ramus et al., 2003;Witruk, Friederici, & Lachmann, 2002;Habib, 2000;von Suchodoletz, 1999). We will start by briefly reviewing two of the most prominent theories in current research on developmental dyslexia, the phonological deficit hypothesis and the auditory deficit hypothesis. ...

In an earlier study we found that mothers of children with speech-language impairment often feel depressed (33%), disappointed (25%) or aggressive (14%) as a consequence of their child's developmental disability [39] . However, it is not clear whether the negative emotional reactions of the mothers stem from stigmatization or are in fact not causally related to the pejorative labeling by the environment. ...

... The finding of the present study also foregrounds the provision of opportunities for children to improve their motor proficiency, especially when it is observed that these opportunities are not granted to all individuals despite their fundamental roles. For instance, children with developmental speech and language disorders rarely participate in play and sports activities due to their failure in establishing relationships with others (Camarata & Conture, 2003;Gertner, Rice, & Hadley, 1994). This matter, as shown by Visscher et al. (2010), leads to lower motor proficiency of children with developmental speech and language disorders compared with their typically developing peers (see also , Visscher, Houwen, Scherder, Moolenaar, & Hartman, 2007). ...

... Desta forma, a revisão evidenciou a importância de monitorar o desenvolvimento do vocabulário, inclusive pela importante relação para o desenvolvimento de habilidades posteriores, como a decodificação e compreensão leitora (19,25) , bem como as formas de uso dos instrumentos para elaboração desta triagem em questão. Com isso, as habilidades de vocabulário receptivo e expressivo foram escolhidas para compor o instrumento, pois a produção de poucas palavras pode ser um dos principais indicadores de atrasos no desenvolvimento da linguagem (19) , característica que pode ser observada em diagnósticos, como no transtorno do desenvolvimento da linguagem (TDL) (26) , transtorno do espectro do autismo (27) e atraso de linguagem (28) . ...

The instrument was developed for the assessment of early language skills in German (Grimm & Doil, 2006) with substantial and significant correlations to direct measures of children's language competence via language tests (correlations between 0.45 and 0.85 e.g., with the SETK-2 or RDLS-III; see Sachse et al., 2007a). Furthermore, the ELFRA-2 shows good prognostic validity for later language skills/language disorders (between 59% and 64% using the RATZ-Index; Sachse et al., 2007b). ...
