    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Partial automation; human factors; event-related potentials; cognitive underload; task interference; additional task; automation experience; automation trust; Partial automation; mänskliga faktorer; Eventrelaterade potentialer; kognitiv underbelastning; arbetsstörningar; sidouppgift; automatiseringserfarenhet; automatiseringsförtroende;

    Sammanfattning : The technological development in recent years is currently reflected in the implementation of more and more advanced driver assistance systems (ADAS). A clear example is found in the automated driving systems being marketed today. LÄS MER

  4. 3. Cross-functional brain imaging of attention, memory, and executive functions : Unity and diversity of neurocognitive component processes

    Författare :Petter Marklund; Lars Nyberg; Akira Miyake; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human memory; executive functions; prefrontal cortex; sustained and transient neural activity; declarative long-term memory; attention; working memory; functional neuroimaging; cognitive control.; Psychology; Psykologi;

    Sammanfattning : The central theme of the present thesis revolves around the exploration of similarities and differences in brain activity patterns invoked by the component processes underlying mnemonic, executive and attentional functions. The primary aim was to identify and functionally characterize commonly recruited brain regions in terms of shared component processes, which has been a largely neglected area of research in cognitive neuroscience.

  5. 4. Attacking predators and fleeing prey : detection, escape and targeting behaviour in birds

    Författare :Ulrika Kaby; Innes Cuthill; Stockholms universitet; []
    Nyckelord :zoology; ethology; birds; animal behaviour;

    Sammanfattning : The aim of this thesis is to further our understanding of predator and prey behaviour and decision making in different attack situations. The thesis deals with escape strategies, predator detection ability and prey targeting behaviour. LÄS MER

  7. 5. Students' narratives from graphical artefacts : Exploring the use of mathematics tools and forms of expression in students' graphicacy

    Författare :Oduor Olande; Karl Göran Karlsson; Astrid Pettersson; Luis Radford; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Critical-analytical approach; Graph comprehension; Graphicacy; Graphical artifacts; Statistical literacy; Semiotics; Mathematical Education; Matematikdidaktik;

    Sammanfattning : The research concerns presented in this dissertation addresses aspects of students’ interaction with commonly occurring graphical artefacts in teaching and learning environments. In particular, focus is on how the students make sense of these artefacts in relation to subject specific tools and forms of expression. LÄS MER
