  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; []

    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. Spike-Based Bayesian-Hebbian Learning in Cortical and Subcortical Microcircuits

    Författare :Philip Tully; Anders Lansner; Matthias Hennig; Gordon Pipa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bayes rule; synaptic plasticity and memory modeling; intrinsic excitability; naïve Bayes classifier; spiking neural networks; Hebbian learning; neuromorphic engineering; reinforcement learning; temporal sequence learning; attractor network; Computer Science; Datalogi;

    Sammanfattning : Cortical and subcortical microcircuits are continuously modified throughout life. Despite ongoing changes these networks stubbornly maintain their functions, which persist although destabilizing synaptic and nonsynaptic mechanisms should ostensibly propel them towards runaway excitation or quiescence.

  4. 3. Babble, grunts, and words : a study of phonetic shape and functional use in the beginnings of language

    Författare :Liselotte Roug-Hellichius; Florien J. Koopmansvan Beinum; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Phonetics; Fonetik; Phonetics; fonetik;

    Sammanfattning : The present study follows in the tradition of those seeking to understand linguistic behavior from a cognitive and socio-biological perspective (Bates, Benigni, Bretherton, Camaioni and Volterra 1979, Lindblom 1992, Hauser 1996) by tracing the development of a non-linguistic vocal behavior in relation to communicative and early lexical advances. More specifically the study focuses on the occurrence of what are termed ìcommunicative gruntsî and their functional relationship to adult based word use in one Swedish boy from 11 to 19 months of age.
