1. Room acoustics and cognitive load when listening to speech
Sammanfattning : The present thesis investigated the effects of background noise or a long reverberation time in learning situations. All studies used spoken texts that were presented above the speech intelligibility threshold, but were degraded enough to make listening more effortful. LÄS MER
2. Experimental study of an intermittent ventilation system in high occupancy spaces
Sammanfattning : Spaces with high occupancy density like classrooms are challenging to ventilate and use a lot of energy to maintain comfort. Usually, a compromise is made between low energy use and good Indoor Environmental Quality (IEQ), of which poor IEQ has consequences for occupants’ health, productivity and comfort. LÄS MER
3. Make It Easier : A psychological perspective on sustainable behavior change
Sammanfattning : Human behavior is the cause of most environmental challenges we face today, and widespread behavioral change is urgently needed across actors and scales. Even though the public perception of the current ecological crisis has changed drastically in recent decades, a corresponding shift in behavior is lacking — unfortunately, mere belief in climate change is a poor predictor of taking action.

4. Effects of environmental acoustic factors, individual differences and musical training on speech perception in simulated classrooms
Sammanfattning : Formal learning takes place primarily through speech perception in classroom environments and is therefore dependent on the listener’s ability to cope with a number of acoustic factors that interfere with the speech signal. As classrooms are inclusive spaces accommodating learners with a broad range of abilities and backgrounds, this research investigated some of the ways in which individual differences in supporting cognitive skills are related to speech perception outcomes in various challenging acoustic environments.

5. Pilots’ decision-making, emotions and cognitive performance in simulated environments
Sammanfattning : The aim of this thesis is to investigate pilots’ performances in distinct simulation environments as related to the phenomena of cognition, emotion and fatigue. By doing so, it provides psychological material to broaden the understanding and possibility to development of pilots’ non-technical skills category related to the operational context. LÄS MER
