  1. 6. Experimental study of an intermittent ventilation system in high occupancy spaces

    Författare :Alan Kabanshi; Patrik Sörqvist; Hans Wigö; Robert Ljung; Hazim Awbi; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermittent airflow; Indoor air quality; Perceived air quality; Thermal sensation; thermal comfort; Air movement acceptability; Convective cooling; Cooling effect.; Intermittent luftflöde; Luftstrålar; Upplevd luftkvalitet; Termisk komfort; Acceptans av luftrörelser; Konvektiv kylning; Kyleffekt.; Hållbar stadsutveckling; Sustainable Urban Development;

    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. 7. Disruption of writing in noisy office environments

    Författare :Marijke Keus van de Poll; Patrik Sörqvist; Stefan Wiens; Högskolan i Gävle; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; background speech; writing; speech intelligibility; Speech Transmission Index; masking; sound source location; working memory capacity; inattention; noise sensitivity; task interruptions; bakgrundsprat; skriva; taluppfattbarhet; Speech Transmission Index; maskering; ljudposition; arbetsminneskapacitet; uppmärksamhet; ljudkänslighet; uppgiftsavbrott; inget Strategiskt forskningsområde SFO ; no Strategic Research Area SFO ;

    Sammanfattning : The overall aim of the four experimental studies included in this dissertation was to investigate the influence of background speech on writing performance. In Paper I, a manipulation of speech intelligibility of background speech, by using the Speech Transmission Index (STI), revealed disruptive effects at lower STI values (i.e. LÄS MER

  4. 8. Make It Easier : A psychological perspective on sustainable behavior change

    Författare :Noah Linder; Stephan Barthel; Therese Lindahl; Robert Ljung; Patrik Sörqvist; Janne Hukkinen; Högskolan i Gävle; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pro-environmental behavior; behavior change; intervention; habits; intentions; information; nudge; choice architecture; miljövänligt beteende; beteendeförändring; vanor; intentioner; information; nudge; valarkitektur; Hållbar stadsutveckling; Sustainable Urban Development;

    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.

  5. 9. How memory of the past, a predictable present and expectations of the future underpin adaptation to the sound environment

    Författare :Anatole Nöstl; Patrik Sörqvist; Daniel Västfjäll; Högskolan i Gävle; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Memory; Expectations; Adaptation; Habituation; Predictions; Attentional capture; Auditory distraction; Minne; förväntningar; anpassning; habituation; prediktioner; fångad uppmärksamhet; auditiv distraktion;

    Sammanfattning : By using auditory distraction as a tool, the main focus of the present thesis is to investigate the role of memory systems in human adaptation processes towards changes in the built environment. Report I and Report II focus on the question of whether memory for regularities in the auditory environment is used to form predictions and expectations of future sound events, and if violations of these expectations capture attention.

  7. 10. Change Detection of the Unexpected : Enhancing change detection of the unexpected in a complex and high risk context – guiding visual attention in a digital display environment

    Författare :Ulrik Spak; Else Nygren; Patrik Sörqvist; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; awareness; change blindness; change detection; command and control; display; feedback; human-computer interaction; inattentional blindness; monitoring; surveillance; visual cue; Människa-dator interaktion; Human-Computer Interaction; Ledningsvetenskap;

    Sammanfattning : Change detection of objects and events in our visual surroundings is sometimes severely difficult, especially if these changes are unexpected. Such failures in change detection may cause huge malicious outcomes in contexts characterized by high levels of complexity and risk. LÄS MER
