Typically developing Spanish-English bilingual children's production of twelve grammatical morphemes was analyzed for accuracy and described as a function of their English mastery, as indexed by mean length of utterance (MLU). Results revealed positive trends in morpheme accuracy as MLU increased. Despite a large degree of between subject variability, the data demonstrated general patterns that were consistent with previous literature, namely that the rate and trajectory of morpheme acquisition differs from monolingual norms, and that particular morphemes are predictably more and less challenging for bilingual children to produce accurately. MLU "cut-points" were suggested based on functional breaks in accuracy for several morphemes. / text

After having worked within the preschool and it’s system for a number of years, we have often reflected over the fact that many educators tend to look at children with language difficulties in several different ways, and many of them being conflicting. Something that might contribute to this problem is the fact that the term itself, language difficulties, is defined differently between individuals, who in turn affects the way educators and preschools deal with the problem. The aim of this study is to create an understanding of the problems related to language difficulties, and how it is being dealt with within the preschool environment. To achieve this we have chosen to work within a qualitative research approach, alongside a discourse analysis. The selection of informants we have chosen consists of ten, qualified educators. Within this study we have collected a variety of descriptions for the term language difficulties, and how these in turn affect the way that children’s language, the typical and the atypical, is developed. As reference material we have chosen to use the paper Med blicken på barnet - Om olikheter inom förskolan som diskursiv praktik, by Palla (2011), and we stick to this theoretical approach throughout the study. Furthermore, we will try to explain the language development of children through developmental psychology and language theories. Through the analysis of the results found in this study, we conclude that the definition and construction of the term language difficulties, varies greatly, but are always seen as correct and true by the individual behind it. This in turn affects the way that educators deal with the children that are affected. In this study, two reoccurring aspects to this have been found, namely, the age of the child, and the responsibility held by the preschool. These aspects seem to be important in forming the image that educators have of the matter, and furthermore shape the way that they value and deal with it.

Past tense verb production in children with specific language impairment and language-matched children with typical language was compared using language samples and a standardized probe (Rice/Wexler Test of Early Grammatical Impairment). Analyses revealed accuracy and error type differences between elicitation types and groups. Results have important clinical practice implications.

Regular (e.g., jumped) and irregular (e.g., fell) past tense verb acquisition in children with typical language development (TL) occurs between ages 3-5. In children with specific language impairment (SLI), acquisition of these forms is extended and errors in spontaneous conversation may even continue into adulthood. However, there is a lack of consensus as to whether probed or spontaneous language samples give a more accurate representation of a child’s linguistic skills. The first aim of this study was to determine if there were differences in regular and irregular past tense verb production accuracy between two Elicitation Methods: probed vs. spontaneous language sampling. The second aim was to determine if accuracy and error patterns differed between children with SLI and children with TL. The participants included 11 children with SLI (mean age: 5 years) and 20 children with TL (mean age: 3 years 6 months). Each participant received a battery of tests to determine language status. This battery included two elicitation methods for regular and irregular past tense: a probe and a spontaneous language sample. The Rice/Wexler Test of Early Grammatical Impairment probed past tense verb production using picture prompts and a standardized verbal routine. Additionally, a language sample was recorded in which participants told three thematically related stories provided spontaneous productions. The first two stories were read by the examiner first and the child was asked to retell it. The first story was presented in the present tense. The second story was presented in the past tense. The third story was made up by the child based on the pictures and the tense was free to vary. These stories provided the language sample that was then transcribed and coded for a statistical analysis of verb production. Within and between groups ANOVAs revealed statistically significant differences between the probe and spontaneous language samples, with the probe yielding higher accuracy for regular and irregular past tense verb production in both groups. There was no significant Group effect or Group by Elicitation Method interaction. Analysis of the types of errors produced revealed a statistically significant Group by Elicitation Method interaction. Post hoc analysis found for regular past tense verbs, children with SLI produced more stem-form errors than children with TL. For irregular past tense forms, children with SLI produced more stem form errors, while children with TL produce more overregularization errors. The observed pattern of errors is consistent with inclusionary criteria for SLI, the literature, and theoretical foundations. The results add to the literature about the accuracy of probe and spontaneous language sample elicitation methods.

Speech-language pathologists are challenged with providing children with treatment that results in the greatest amount of improvement in the least amount of time. To aid in this challenge, we examined how quickly and efficaciously seven children with a specific language impairment (SLI) learned verbs compared to seven children with typical language (TL) development. Each child was taught the meaning and use of six nonsense verbs. Nonsense verbs were used to ensure that the target verbs had never been heard by any of the participants before the experiment and allowed us to control verb exposure. Each participant received up to four training sessions of 30-minutes each. During these sessions, the examiner utilized naturalistic conversational techniques and play activities with carefully selected sets of toys that corresponded to the meaning of the target words. The training sessions were ended when children demonstrated 100% accuracy in their understanding of the verbs and 50% accuracy in their production during a probe task. All sessions were audio-recorded and the experimenters and childs utterances were reliably coded. Analysis revealed that the two groups received the same input from the experimenter in terms of the number and type of exposures to the verbs. We examined the childrens nonsense verb productions for their rate and quality. Rate of verb acquisition was measured by counting: 1) the number of sessions required before the criteria for learning was met; 2) the number of exposures before childs first spontaneous production of each target verb; and 3) the number of exposures before childs first elicited production of each target verb. Quality of verb acquisition was measured by counting: 1) the number of alternative real verbs substituted for a nonsense verb and 2) the accuracy of transitive target verb usage. Although the results were not statistically significant for any of the measures tested, there was a trend for children with SLI to learn the target nonsense verbs more slowly but just as

Generally prosody is described as the rhythmic, dynamic and melodic features of language. Prosody is further often described as suprasegmental, since its properties go beyond vowels and consonants, which are segmental characteristics of language. A relationship between prosody and music has been noticed and described for several decades. At present, there are several studies proving relationship between prosodic and musical abilities.   The aim of the present study was to construct a test for prosodic non-linguistic perception and production regarding intonation and rhythm. The test was tried out on 16 children with typical language development aged 4;6-7;6 years.   Before testing of ITAP each participant were asked about musical experience. For formal assurance that the participants had typical language development a pretesting was performed.   The results demonstrate an even range and therefore the complexity of ITAP seems to be on a representative level. Furthermore, ITAP is viable and the design is advantageous. The results of the present study suggest that both phonological working memory and grammatical ability are related to the aspects of intonation tested in ITAP.   The study contributes to the knowledge about possible relations between prosodic and musical abilities, and it provides guidance on what children with typical language development are expected to achieve on ITAP.

Abstract This study examined Finnish children’s narrative skills using a picture-based story generation task. 4- to 8-year-old children with typical development (n = 172), 5- to 7-year-old children with specific language impairment (SLI) (n = 19) and 5- to 10-year-old children with autism spectrum disorder (ASD) (n = 16) participated in the study. Linguistic (productivity, syntactic complexity, grammatical accuracy) and pragmatic (referential accuracy, event content, mental state expressions, discourse features, and story comprehension) measures were used so as to gain a comprehensive picture of narrative skills. The choice of measures was based on the narrative abilities of the participants, and not all measures were used with all participants. In typically developing children, a subtle development trend was seen in all the measures used, but significant differences between consecutive age-groups were mostly seen in younger participants. The relationship between narrative productivity measures and event content was found to be important. The number of different word tokens was, in particular, useful in explaining the event content. For children with SLI, the linguistic and pragmatic aspects of narration were demanding. Their stories were short and contained less information than those of their control. Their referential and grammatical accuracy was also poorer than among typically developing children, and they showed difficulties in expressing the mental states of the story characters and in story comprehension. Children with ASD produced narratives with an almost similar linguistic structure to those of their control children. However, children with ASD showed difficulties in the pragmatic aspect of narration, in establishing informative story content and in story comprehension. They also tended to include irrelevant information in their stories, which was not seen to that extent in cases of typical development. This dissertation shows a development in 4- to 8-year-olds’ narratives that seems to occur around the ages of 4 and 5. Narrative difficulties seem to be related to both SLI and ASD, but are more wide-ranging in SLI, whereas in ASD difficulties focus on the pragmatic aspects of narration. / Tiivistelmä Tutkimuksessa selvitettiin, millaiset ovat suomalaislasten kuvasarjakerronnan avulla arvioidut kerrontataidot. Tutkimukseen osallistui 4–8-vuotiaita tyypillisesti kehittyneitä lapsia (n = 172), 5–7-vuotiaita lapsia, joilla on kielellinen erityisvaikeus (SLI) (n = 19) ja 5–10-vuotiaita lapsia, joilla on autismikirjon häiriö (ASD) (n = 16). Tutkimuksessa käytettiin lingvistisiä (produktiivisuus, syntaksin monipuolisuus, kieliopillinen tarkkuus) ja pragmaattisia (viittaussuhteiden tarkkuus, tapahtumasisältö, mielentilailmaukset, diskurssipiirteet, kertomuksen ymmärtäminen) muuttujia, jotta kerrontataidoista saadaan kokonaisvaltainen kuva. Kaikkia muuttujia ei käytetty kaikkien tutkittavien kesken, vaan tutkimusmenetelmien valinta perustui tutkittavien kerronnan piirteisiin. Tyypillisesti kehittyvien lasten kerrontataidot kehittyivät kaikkien käytettyjen muuttujien osalta, mutta peräkkäisissä ikäryhmissä merkitsevä muutos havaittiin vain nuorempien ikäryhmien välillä. Kerronnan produktiivisuuden ja tapahtumasisällön välillä havaittiin yhteys, ja erityisesti eri saneiden määrä oli merkitsevä tapahtumasisällön selittäjä. Kerronnan lingvistinen ja pragmaattinen hallinta oli haastavaa lapsille, joilla on SLI. Heidän kertomuksensa olivat pituudeltaan, tapahtumasisällöltään ja mielentilailmauksiltaan niukempia sekä viittaussuhteiltaan epätarkempia kuin tyypillisesti kehittyvien lasten kertomukset. Lapset, joilla on SLI, tuottivat enemmän kieliopillisia virheitä kuin kontrollilapset, ja myös tarinan ymmärtäminen oli heille haastavaa. Kertomuksen lingvistinen rakenne oli likimain samankaltainen tyypillisesti kehittyneillä lapsilla ja lapsilla, joilla on ASD. Lapset, joilla on ASD, tuottivat tapahtumasisällöltään niukempia kertomuksia kuin kontrollilapset, ja lisäksi heidän tarinansa sisälsivät irrelevanttia tietoa. Kertomuksen ymmärtäminen oli myös vaikeaa lapsille, joilla on ASD. Tutkimus osoittaa, että 4–8-vuotiaiden kerrontataidoissa on kehitystä, mikä vaikuttaa olevan aktiivista erityisesti 4–5 ikävuoden aikana. Kerronnan vaikeudet ovat kielellisessä erityisvaikeudessa laaja-alaisia, kun taas autismikirjossa vaikeudet näkyvät ennemmin kerronnan pragmaattisessa hallinnassa.
