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

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

   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

3. 2. Attention capture by sudden and unexpected changes : a multisensory perspective

   Författare :Erik Marsja; Jessica K. Ljungberg; Gregory Neely; Patrik Hansson; François Vachon; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attention Capture; Tactile; Auditory; Visual; Crossmodal; Bimodal; Distraction; Short-term memory; Attention; Psychology; psykologi;

   Sammanfattning : The main focus for this thesis was cross-modal attention capture by sudden and unexpected sounds and vibrations, known as deviants, presented in a stream the same to-be-ignored stimulus. More specifically, the thesis takes a multisensory perspective and examines the possible similarities and differences in how deviant vibrations and sounds affect visual task performance (Study I), and whether the deviant and standard stimuli have to be presented within the same modality to capture attention away from visual tasks (Study II).

4. 3. FEAR - A process influenced by concurrent processing demands

   Författare :Anna Bjärtå; Örjan Sundin; Elaine Fox; Mittuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attention; Fear; Performance; Processing resources;

   Sammanfattning : Fear is a central aspect in mammalian evolution, prompting escape from and avoidance of threat and dangers. Therefore, it is reasonable to believe that we have a well developed system to detect dangers and quickly respond to them. LÄS MER

5. 4. Orchestrating Innovation in the Multinational Enterprise : Headquarters Involvement in Innovation Transfer Projects

   Författare :Henrik Dellestrand; Ulf Andersson; Martin Johanson; Andrew Delios; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Multinational enterprise; headquarters-subsidiary relationships; innovation transfer; involvement; orchestration; resource allocation; attention; subsidiary evolution; Business studies; Företagsekonomi; Business Studies; Företagsekonomi;

   Sammanfattning : In the past several decades research has emphasized innovation development and transfer as key issues when investigating the multinational enterprise (MNE). This thesis focuses on the question of what factors make headquarters involve itself in innovation transfer projects taking place between a sending and a receiving subsidiary within the MNE. LÄS MER

7. 5. Applications of Diversity and the Self-Attention Mechanism in Neural Networks

   Författare :Axel Berg; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; point cloud; self-attention; keyword spotting; deep learning; computer vision; machine learning; label diversity;

   Sammanfattning : This thesis covers three contributions in applications of neural networks. The first is related to diversity and ensemble learning, while the other two cover novel applications of the self-attention mechanism. An important aspect of training a neural network is the choice of objective function. LÄS MER
