2. 1. Fearful attention : Investigating event-related potentials in spider phobia

   Author : Joakim Norberg; Stefan Wiens; Jonas Persson; Harald Schupp; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; attention; phobia; event-related potential; Psychology; psykologi;

   Abstract : 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. READ MORE

4. 2. Applications of event-related potentials in the study of attention

   Author : Magnus Lindgren; Institutionen för psykologi; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; event-related potentials; attention; nicotine; toxic encephalopathy; hypoglycaemia; P300; Psychology; Psykologi;

   Abstract : 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. READ MORE

5. 3. Auditory event-related potentials and cognitive outcome after very preterm birth

   Author : Holger Hövel; Lund Pediatrik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Preterm; Event-related potentials; Mismatch negativity; Magnetic resonance imaging; developmental outcome;

   Abstract : 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. READ MORE

6. 4. On Signal Dependent Basis Functions, Estimation of Event Related Potentials and Multiple Window Spectrum Analysis

   Author : Maria Hansson; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal processing; spectrum analysis; multiple windows; anaesthesia; Nb-trough; damped sinusoids; single ERP; Signal dependent basis functions; Event Related Potentials;

   Abstract : 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). READ MORE

7. 5. Examining neurobehavioral effects of chemosensory exposure to local irritants using event related potentials

   Author : Stephanie Anja Juran; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : 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. READ MORE
