2. 1. The Effects of Age of Onset on VOT in L2 Aquisition and L1 Attrition : A Study of the Speech Production and Perception of Advanced Spanish-Swedish Bilinguals

   Author : Katrin Stölten; Niclas Abrahamsson; Ulla Sundberg; Kirk Sullivan; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; second language acquisition; first language attrition; maturational constraints; critical period; voice onset time; stop production; categorical perception; activation threshold hypothesis; L1 use; highly proficient L2 learners; L1 Spanish; L2 Swedish; Bilingualism; tvåspråkighet;

   Abstract : This thesis explores the role of age in second language (L2) acquisition and first language (L1) attrition. The focus is on Voice Onset Time (VOT) in the production and categorical perception of word-initial L1 and L2 stops in highly advanced L1 Spanish learners of L2 Swedish. READ MORE

4. 2. The acquisition of contrast : a longitudinal investigation of initial s+plosive cluster development in Swedish children

   Author : Fredrik Karlsson; Kirk P. H. Sullivan; Peter E. Czigler; Marilyn M. Vihman; Umeå universitet; []
   Keywords : HUMANIORA; HUMANITIES; phonological contrast; speech development; place and manner of articulation; aspiration; structural complexity; acoustic cues; homonym production; Phonetics; Fonetik;

   Abstract : This Thesis explores the development of word-initial s+plosive consonant clusters in the speech of Swedish children between the ages of 1;6 and 4;6. Development in the word-initial consonant clusters is viewed as being determined by 1) the children’s ability to articulate the target sequence of consonants, 2) the level of understanding of which acoustic features in the adult model production are significant for the signalling of the intended distinction, and 3) the children’s ability to apply established production patterns only to productions where the acquired feature agrees with the adult target, to achieve a contrast between rival output forms.

5. 3. Mother tongue - Phonetic Aspects of Infant-Directed Speech

   Author : Ulla Sundberg; Anne Fernald; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; infant-directed speech; language acquisition; mother-infant interaction; Phonetics; Fonetik; Phonetics; fonetik;

   Abstract : Phonetic aspects of mother-infant interaction are discussed in light of a functionalist Mother-infant phonetic interaction (MIPhI) model. Adults addressing infants typically use a speech style (infant-directed speech, IDS) characterized by, for instance, extensive suprasegmental (prosodic) modulations. READ MORE

6. 4. Sound Generation and Propagation in the Human Upper Airways

   Author : Lukas Schickhofer; Mihai Mihaescu; Anders Dahlkild; Mats Karlsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

   Abstract : The human upper airways embrace the source of phonation and affect the modulation of the voice, which is of vital importance for communication. Moreover, unwanted sounds may be generated in the upper airways due to elastic, collapsible parts that are susceptible to flow-induced vibration and resonance. READ MORE

7. 5. Tailoring and standardizing the assessment of ability and disability in ADHD and autism : the development of WHO ICF core sets

   Author : Soheil Mahdi; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The concept of health has evolved over time and is today considered a multidimensional construct that involves not only absence of impairments or pathologies, but also quality of life and individual functioning. This conceptualization is especially important to individuals with neurodevelopmental disorders (NDD), as these are characterized by early-onset symptoms that tend to persist into adulthood, interfering with individual well-being, daily life activities and engagement in society.
