The diploma thesis discusses family communications during Mealtimes. The first part defines the basic theoretical concepts of the theory of children's speech and research associated with it, it defines preschool child development with an emphasis on language and further defines the concept of family communication and child directed speech. At the end of the theoretical part the thesis explains the importance of food/meals in family life. The theoretical part is mainly based on professional literature. The second part consists of five case studies that focus on the analysis of video communications during family meals. All families that participated on the recording signed a consent. The information was also obtained with the help of sociologically oriented survey about adult participants. All recordings were transcribed according to the CHAT system guidelines, which is part of the CHILDES database. The results are compared with the findings of the professional literature.

The following diploma thesis addresses linguistic speech in the children's program at the Radio Junior Club. The first section describes verbal expressions, defines basic theoretical concepts related to the stratification of Czech language, defines child listeners with a focus on the pre-school development period as well as the primary and middle school period and also explains the concept of child-oriented speech. The structure of Czech Radio and individual programs at Radio Junior with emphasis on the Radio Junior Club are described at the end of the theoretical section. The practical section contains two analyses describing the moderator's language and how it is responded to positively according to sound level, lexicology, morphology and syntax. The recordings were taken from the Czech Radio archive and the ORAL2013 transcriptional system, which was adapted for analysis purposes, was used to transcribe the spoken language. The results of the analyses were compared and generalized along with findings in expert literature.

The main results of the PhD thesis are described in the summary. The main objective of the thesis is to define the acquisition of lexical and morphosyntactic features of Lithuanian adjective. The analysis is based on the large quantity of linguistic data (~ 400 000 words), which is the corpus of four children compiled according the method of longitudinal observation. The study has interchangeably applied several methods of analysis: longitudinal observation, corpus linguistics, error analysis and comparative method. Statements to be Defended 1. Lexical features of adjectives are acquired by children with difficulties: they often confuse adjectives of a single semantic group and make many errors. 2. Children easily acquire morphosyntactic features of adjectives: they do not make many errors. Some errors may be observed only in cases, when adjective paradigms do not coincide with noun paradigms. 3. Lexical and morphosyntactic features of adjectives are acquired simultaneously. The meaning of adjective is realised only when multi-word combinations and morphosyntactic features have been acquired. 4. The acquisition of adjectives correlates with the individual language development. Bigger lexical variety of adjectives is more characteristic to children with early and late language development, if compared to children with typical language development. Morphosyntactic features of adjectives do not pose problems to children with late language development. 5. The acquisition of...

Unga barn föredrar redan från födseln att lyssna till positivt tal, vilket karaktäriserar barnriktat tal. Idenna studie kontrasterades neutral och positiv känsla i ett ordinlärningsparadigm där tittiden hos 16-månader gamla, svensktalande barn (N=12) analyserades när de testades på två påhittade ord.Målorden presenterades antingen i positivt barnriktat tal eller neutralt barnriktat tal. Detta gjordes föratt se om det positiva barnriktade talet underlättar inlärningen av nya ord. Deras tittid på detefterfrågade objektet analyserades sedan med en tvåvägs-ANOVA. Det fanns inga signifikantaskillnader mellan röstlägena. Slutsatsen som drogs var att hypotesen, att tittiden för det objekt sompresenteras i positivt tal är längre, inte kunde bekräftas men inte heller förkastas på grund av problemmed datainsamlingen samt dataanalysen. Inför framtida studier rekommenderas att utöka antaletdeltagare, samt undersöka andra variabler som kan påverka den tidiga ordinlärningen. / Already from birth young children prefer to listen to positive speech, which is a characteristic of childdirected speech. In this study neutral and positive tone was contrasted in a word-learning paradigmwhere the eye-movement of 16-month-old Swedish speaking children (N= 12) were analysed whenthey were tested on two made-up words. The words were either presented in neutral child-directedspeech or positive child-directed speech. This was done to see if the early word-learning is facilitatedby positive tone. The looking time was then analysed by a two-way ANOVA, and there was nosignificant difference between the two emotions. The conclusion drawn was that the hypothesis, thatthe looking time of the children that presented with positive child-directed speech would be longer,could not be confirmed nor rejected due to problems with collecting data and data analysis. Prior tofuture studies it is recommended to expand the number of participants, as well as examine othervariables that may affect early word learning.

In this thesis, the usage of iconic expressions, or sound symbolic expressions, is investigated in Swedish child-directed speech during the first two years of life. Furthermore, it is explored whether there is an effect of the usage of sound symbolism on productive vocabulary at 2;0 years. Ten monolingual Swedish and typically-developing children and their parents were selected at the ages of 0;3, 0;6, 0;9, 1;0, 1;3, 1;6, 1;9 and 2;0 years. The sound symbolic expressions were extracted, classified and analysed. One finding is that sound symbolic expressions are used by all parents in varying degrees from sparsely to abundantly. On average 0,9 sound symbolic expressions were used per minute by all parents. There was no significant effect of the usage of sound symbolism on productive vocabulary. Nevertheless, this work shows that iconicity is used in early childhood and might be a part of the register child-directed speech. Further studies should investigate more thoroughly the effect of iconicity on language acquisition. / I denna studie undersöktes ikoniska, eller ljudsymboliska, uttryck i svenskt barnrikat tal under barnets första två levnadsår. Utöver detta testades det om det fanns någon effekt av användning av ljudsymbolik på barnets produktiva ordförråd vid 2;0 år. Tio enspråkiga svenska och typiskt-utvecklade barn och deras föräldrar valdes ut vid 0;3, 0;6, 0;9, 1;0, 1;3, 1;6, 1;9 och 2;0 år och de ljudsymboliska uttrycken extraherades, klassificerades och analyserades. Ett resultat var att alla föräldrar använde sig av ljudsymboliska uttryck; varierande från lite till mycket. I genomsnitt användes det 0,9 ljudsymboliska uttryck per minut av alla föräldrarna. Ingen signifikant effekt på det produktiva ordförrådet kunde hittas. Trots detta så visar detta arbete att ikonicitet används under den tidiga barndomen och att ikonicitet kanske är en del av talstilen ‘barnriktat tal’. Framtida forskning kan undersöka ikonicitetens påverkan på språkinlärning mer ingående. / Modelling infant language acquisition from parent-child interaction (MINT)

Abstract The present longitudinal follow-up study had two main goals. Firstly, this study aimed to describe aspects of maternal interactive/communicative behaviour that could be considered constitutive in sensitive responsiveness. Secondly and most importantly, it aimed to find predictive relations between characteristics of mother-infant interaction around the onset of infant intentional communication and subsequent child communicative and linguistic development. The participants were 27 Finnish-speaking mothers and their healthy first-born infants. Analyses of the amount and types of maternal and infant communicative acts as well as maternal responses to infant signals were carried out from videotaped free-play samples at the infants' age of 10 months. In addition, the CARE-Index was used to rate maternal sensitivity and infant co-operativity. At 12 months, children's communicative and linguistic skills were assessed by using the MacArthur Communicative Development Inventories and the Communication and Symbolic Behaviour Scales. At 30 months, the Reynell Developmental Language Scales III was used to assess comprehensive and expressive language. The results suggest that maternal activity in eliciting interaction and conversational interchanges is characteristic of sensitive responsiveness around the onset of infant intentionality. However, very distinctive aspects of verbal behaviour that might be constitutive in sensitive responsiveness were not found — probably as a result of considerable individual variation in all aspects of maternal as well as infant interactive/communicative behaviour that were analysed. As predictors of communicative and linguistic skills at 12 months, both maternal and infant characteristics made a significant contribution. In general, the predictive relations found were quite specific. In turn, except for the predictive validity of maternal sensitivity for comprehensive language at 30 months, later language outcomes were predicted only by children's communicative and linguistic skills at 12 months, suggesting that over time, language development becomes increasingly child-driven. Individual differences in early communicative capacities may also to some extent mask the language-facilitating effects of parenting. On the other hand, some potentially facilitating effects of parental behaviour may be elicited by the infant's well-advanced communicative skills. The importance to acknowledge transactional processes in parent-child interaction is highlighted — both in future research and clinical applications.

Variationsmängder är en egenskap i barnriktat tal som karaktäriseras av successiva yttranden i vilka den vuxne talaren upprepar och omformulerar sitt budskap med en konstant intention. Syftet med studien var att undersöka variationsmängder över tid i tal riktat till barn i åldrarna 7-33 månader. Målet var att studera vilka typer av yttranden som dominerar variationsmängderna vid olika åldrar, samt vilka yttrandetyper som tenderade att förekomma tillsammans inom variationsmängderna. Vidare undersöktes intention och tempusförändringar hos verb i dessa variationsmängder. Ett skript skrevs för att kategorisera yttrandetyper med data från en korpus över barnriktat tal. Resultatet undersöktes sedan kvantitativt utifrån fyra åldersgrupper. Yttrandenas komplexitet inom variationsmängder visade sig stiga ju äldre barn det rörde sig om. Vidare sågs en skillnad i den vuxnes intention då barnen blev äldre, samt en minskning i användandet av interjektioner i kombination med ja/nej-frågor och komplexa satser ju äldre barnen blev. En tolkning av resultatet föreslogs vara att den vuxne själv tenderar att hålla i båda sidor av konversationen då de talar med yngre barn till skillnad från när de talar med äldre, mer verbala, barn som själva kan bidra med svaret. / Variation sets are a feature in child-directed speech characterized by successive utterances in which the adult speaker repeats and reorders their message with a constant intent. The aim of this study was to investigate variation sets over time in speech directed to children in the ages 7-33 months. The purpose was to study which types of utterances that dominates the variation sets at different ages, and which utterance-types that tend to co-occur within the variation sets. Furthermore intent was studied as well as change in verb tense in these variation sets. A script was written to categorize types of utterances with data from a corpus consisting of child directed speech. A quantitative research was performed on the results based on four different age groups. The complexity of the utterances within variation sets was shown to grow with the increasing age of the children. Furthermore a noticeable difference was observed in the intent of the adult speaker, correlating with the age of the child, and also a decrease in use of interjection combined with yes/no- questions and complex utterances the older the children were. A suggested interpretation of the result was that the adult tend to take both sides of the conversation when the children are young as opposed to when they speak to older, more verbal, children that can provide the answer themselves.

En hög andel repetitioner är ett av de utmärkande dragen i barnriktat tal. Tidigare forskning har visat att andelen repetitioner i barnriktat tal varierar beroende på barnets ålder. Dessutom tyder forskningen på att repetitioner i barnriktat tal kan vara främjande för språkutvecklingen. Syftet med studien var att undersöka eventuella variationer över tid i andelen repetitioner i barnriktat tal under det första levnadsåret, samt försöka hitta ett samband mellan detta och barnens språkliga utveckling. Repetitionerna i föräldrarnas tal hos tio förälder-barn-dyader då barnet var 3, 6, 9 och 12 månader undersöktes kvantitativt. Exakta och varierade självrepetitioner samt exakta och varierade repetitioner av barnens yttranden undersöktes och jämfördes med samma barns språkliga nivå vid 18 månader. Resultatet visade att andelen exakta självrepetitioner var cirka en tredjedel lägre vid 12 månaders ålder än vid de tre tidigare inspelningstillfällena. Den totala andelen repetitioner av barnens yttranden mer än fyrdubblades från 3 till 12 månader. Ett samband kunde påvisas mellan repetitionerna under det första levnadsåret och barnens språkutveckling, där en låg andel exakta självrepetitioner vid 6 till 9 månader korrelerade med en hög språklig nivå vid 18 månader. Som en tolkning av resultatet föreslogs kopplingar mellan barnens aktiva språkbruk och repetitionerna i föräldrarnas tal. / A high proportion of repetitions is one of the distinctive features of child-directed speech (CDS). Research has shown that the percentage of repetitions in CDS varies over time depending on the age of the child. In addition, it is suggested that repetitions in CDS correlate with child language development. The aim of the study was to investigate the possible variations over time in the percentage of repetitions in CDS during the child’s first year, and to try to find a connection between repetitions and the child’s language development. Repetitions in parent speech in ten parent-child dyads as the children were 3, 6, 9 and 12 months old were investigated quantitatively. Exact and varying self-repetitions and exact and varying repetitions of the child’s utterances were investigated and compared to the same children’s linguistic level at 18 months of age. The results showed that the percentage of exact self-repetitions was more than 30 percent lower at the age of 12 months than at 3, 6 and 9 months of age. The total percentage of repetitions of the child’s utterances increased more than four times from 3 to 12 months of age. A connection was found between the repetitions during the child’s first year and the child’s language development, indicating that a low percentage of exact self-repetitions at 6 to 9 months of age correlated with a high vocabulary at 18 months of age. A link between the expressive language of the child and the repetitions in parents’ speech was suggested. / MINT: Modelling infant language acquisition from parent-child interaction (MAW 2011.007)
