1. The language learning infant: Effects of speech input, vocal output, and feedback
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
2. On Perceived Exertion and its Measurement
Sammanfattning : The general aim of the thesis is to answer questions on general and differential aspects of perceived exertion and on the measurement of its intensity variation. Overall perceived exertion is commonly treated as a unidemensional construct. This thesis also explores its multidimensional character. Four empirical studies are summarized (Study I-IV). LÄS MER
3. On Enhancement and Quality Assessment of Audio and Video in Communication Systems
Sammanfattning : The use of audio and video communication has increased exponentially over the last decade and has gone from speech over GSM to HD resolution video conference between continents on mobile devices. As the use becomes more widespread the interest in delivering high quality media increases even on devices with limited resources. LÄS MER
4. Getting a Feel for Tactile Space : Exploring Haptic Perception of Microtexture
Sammanfattning : The present thesis is based on three studies that research different aspects of fine texture perception. The goal is to better understand the mechanisms involved in haptic perception of textures below 200 µm, also known as microtextures. LÄS MER
5. Quantitative and qualitative analysis of touch, cold and warmth in health, neuropathic pain and fibromyalgia
Sammanfattning : The general aim of the present thesis is to examine tactile and thermal perceptual (dys)function by quantitative and qualitative tests of patients with neuropathic pain or fibromyalgia, and to compare results with those of healthy persons. A specific aim is to provide individual data for diagnostic purposes, specific to touch, cold, and warmth (profiles). LÄS MER
