1. Fearful attention : Investigating event-related potentials in spider phobia
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
2. Applications of event-related potentials in the study of attention
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
3. Auditory event-related potentials and cognitive outcome after very preterm birth
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. Examining neurobehavioral effects of chemosensory exposure to local irritants using event related potentials
Sammanfattning : The aim of this thesis was to examine whether unpleasant odors disturb cognitive task performance. At first glance, it seems intuitive that for example the smell of fire smoke would immediately interrupt my current writing at the computer. LÄS MER
