  2. 1. Effects of peripheral auditory adaptation on the discrimination of speech sounds

    Author : Francisco Lacerda; Hartmut Traunmüller; Olle Engstrand; Björn Lindblom; Louis Pols; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Adaptation; discrimination; categorical perception; Phonetics; Fonetik; Phonetics; fonetik;

    Abstract : This study investigates perceptual effects of discharge rate adaptation in the auditory-nerve fibers. Discrimination tests showed that brief synthetic stimuli with stationary formants and periodic source were better discriminated when they had an abrupt as opposed to a gradual onset (non-adapted vs adapted condition).

  4. 2. Effects of environmental acoustic factors, individual differences and musical training on speech perception in simulated classrooms

    Author : Douglas MacCutcheon; Robert Ljung; Daniel Västfjäll; Högskolan i Gävle; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; speech in noise; cognition; perception; musical training; spatial listening; virtual classroom environment; bakgrundsljud; kognition; taluppfattning; musikalisk träning; rumsligt lyssnande; virtuella klassrumsmiljöer; Hållbar stadsutveckling; Sustainable Urban Development;

    Abstract : Formal learning takes place primarily through speech perception in classroom environments and is therefore dependent on the listener’s ability to cope with a number of acoustic factors that interfere with the speech signal. As classrooms are inclusive spaces accommodating learners with a broad range of abilities and backgrounds, this research investigated some of the ways in which individual differences in supporting cognitive skills are related to speech perception outcomes in various challenging acoustic environments.

  5. 3. On-scalp MEG using high-Tc SQUIDs: Measuring brain activity with superconducting magnetometers

    Author : Christoph Pfeiffer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-Tc SQUID; neuroimaging; magnetoencephalography; localization; on-scalp MEG; sensor array; magnetometer;

    Abstract : This thesis describes work done towards realizing on-scalp magnetoencephalography (MEG) based on high critical temperature (high- T c) superconducting quantum interference device (SQUID) sensors. MEG is a non-invasive neuroimaging modality that records the magnetic fields produced by neural currents with good spatial and high temporal resolution. READ MORE
