1. 1. Perceptual reorganization of vowels : Separating the linguistic and acoustic parts of the mismatch response

   Författare :Ellen Marklund; Francisco Lacerda; Iris-Corinna Schwarz; Riitta Salmelin; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; language acquisition; infants; speech perception; MMR; MMN; perceptual reorganization; Linguistics; lingvistik;

   Sammanfattning : During the first year of life, infants go from perceiving speech sounds primarily based on their acoustic characteristics, to perceiving speech sounds as belonging to speech sound categories relevant in their native language(s). The transition is apparent in that very young infants typically discriminate both native and non-native speech sound contrasts, whereas older infants show better discrimination for native contrasts and worse or no discrimi­na­tion for non-native contrasts.

3. 2. Phonological Adoption through Bilingual Borrowing : Comparing Elite Bilinguals and Heritage Bilinguals

   Författare :Memet Aktürk-Drake; Niclas Abrahamsson; Sarah Thomason; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; loanword phonology; language contact; bilingualism; second-language acquisition; perceptual salience; language dominance; linguistic variation; sociolinguistics; Turkish; Bilingualism; tvåspråkighet;

   Sammanfattning : In the phonological integration of loanwords, the original structures of the donor language can either be adopted as innovations or adapted to the recipient language. This dissertation investigates how structural (i.e. phonetic, phonological, morpho-phonological) and non-structural (i. LÄS MER

4. 3. Emergence of words : Multisensory precursors of sound-meaning associations in infancy

   Författare :Eeva Klintfors; Francisco Lacerda; Daniel Swingley; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; language acquisition; word acquisition; auditory-visual; multisensory; sound-meaning association; distributional learning; perceptual salience; infancy; språkinlärning; ordinlärning; audio-visuell; multisensorisk; förbindelser mellan ljud och betydelse; distributionell inlärning; perceptuell prominens; spädbarn; Phonetics; Fonetik; Phonetics; fonetik;

   Sammanfattning : This thesis presents four experimental studies, carried out at the Phonetic laboratory, Stockholm University, on infants’ ability to establish auditory-visual sound-meaning associations as a precursor of early word acquisition. Study I reports on the effect of linguistic variance on infants’ ability (3- to 20-months) to establish sound-meaning associations. LÄS MER

5. 4. The language learning infant: Effects of speech input, vocal output, and feedback

   Författare :Lisa Gustavsson; Francisco Lacerda; Roger Moore; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; human; language; language acquisition; perception; production; humanoid; development; model; embodied system; speech signal processing; vocal tract morphology; acoustic; speech input; information processing; scaling; interaction; growth; infant; imitation; feedback; perceptual salience; modeling; Phonetics; Fonetik; Phonetics; fonetik;

   Sammanfattning : This thesis studies the characteristics of the acoustic signal in speech, especially in speech directed to infants and in infant vocal development, to gain insight on essential aspects of speech processing, speech production and communicative interaction in early language acquisition. Three sets of experimental studies are presented in this thesis. LÄS MER

7. 5. Self-motion and Presence in the Perceptual Optimization of a Multisensory Virtual Reality Environment

   Författare :Alexander Väljamäe; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Determining the perceptually optimal resolution of multisensory renderingmight help to foster the development of cost-effective, highly immersivemulti-modal displays for mediated environments (e.g. virtual and augmentedreality). LÄS MER
