Sammanfattning : Previous studies showed that emotional pictures capture attention. Further, this effect was decreased by manipulating spatial attention. In contrast, studies produced mixed findings for effects of perceptual load on attention to emotional pictures. Emotional pictures can be phobic or nonphobic. LÄS MER
Sammanfattning : Event-related potentials were measured in a series of studies where issues concerning attention were of special interest. In particular, the P300 was used as an index of controlled attention. Papers I and III studied nicotine effects on the P300. LÄS MER
Sammanfattning : Children born before 32 gestational weeks have a high incidence of neuropsychological deficits. The structural and functional correlates of such impairments in preterm infants are incompletely understood, and early diagnostic tools are needed, but still lacking. LÄS MER
4. On Signal Dependent Basis Functions, Estimation of Event Related Potentials and Multiple Window Spectrum Analysis
Sammanfattning : The three parts of this thesis are different examples of utilization of signal dependent basis functions in the estimation procedure. The first part surveys a number of parametric methods applied to estimation of single ERP (P300). LÄS MER
5. Impulse Response Identification Applied to Estimation of Event-Related Potentials and Non-Intrusive Echo Path Analysis
Sammanfattning : This thesis consists of five parts in which problems in two fields, medical and telecommunication, have been studied. In the first part, a prediction algorithm, the Prony method, for estimation of frequencies and damping factors of sinusiods is developed for a coloured noise disturbance. LÄS MER
