  • Jóhannesson, Ómar I.; Kristjansson, Arni; Thornton, Ian M. (Wiley-Blackwell, 2017-03-02)
    In previous studies we have shown that human foraging patterns appear to be constrained by attention. However, we also noted clear individual differences in foraging ability, where some individuals can apparently keep more than one target template in ...
  • Brinkhuis, M. A. B.; Brascamp, J. W.; Kristjansson, Arni (SAGE Publications, 2018-11)
    During visual search, selecting a target facilitates search for similar targets in the future, known as search priming. During bistable perception, in turn, perceiving one interpretation facilitates perception of the same interpretation in the future, ...
  • Spagnol, Simone; Hoffmann, Rebekka; Herrera Martínez, Marcelo; Unnthorsson, Runar (Elsevier BV, 2018-07)
    Translating visual representations of real environments into auditory feedback is one of the key challenges in the design of an electronic travel aid for visually impaired persons. Although the solutions currently available in the literature can lead ...

    An exciting possibility for compensating for loss of sensory function is to augment deficient senses by conveying missing information through an intact sense. Here we present an overview of techniques that have been developed for sensory substitution ...
  • Ólafsdóttir, Inga María (University of Iceland, School of Health Sciences, Faculty of Psychology, 2020-11)
    Visual attention has traditionally been studied with single-target search tasks where observers look for a single target and make a response, then the search is over and the trial ends. These studies have furthered our knowledge of visual attention ...
  • Olason, Daniel; Hayer, Tobias; Meyer, Gerhard; Brosowski, Tim (Frontiers Media SA, 2017-07-25)
    In October 2008, Iceland experienced the fastest and deepest financial crisis recorded in modern times when all three major banks went bankrupt in less than 2 weeks. The purpose of this follow-up study is to examine potential changes in participation ...
  • Spagnol, Simone; Hoffmann, Rebekka; Kristjansson, Arni; Avanzini, Federico (Acoustical Society of America (ASA), 2017-04)
    Stimulus order has been reported to affect perceived loudness. This letter investigates how temporal order affects distance discrimination of receding and approaching pairs of sound sources rendered binaurally in the anechoic near-field. Individual ...
  • Klein, Sabine; Kohler, Sara; Krüerke, Daniel; Templeton, Arnoud; Weibel, Adrian; Haraldsson, Erlendur; Nahm, Michael; Wolf, Ursula (S. Karger AG, 2017-10-26)
    Hintergrund: Wissenschaftliche Studien zum mentalen Zustand sterbender Personen in den Wochen und Tagen vor dem Tod liegen bisher nur vereinzelt vor. Bekannt ist, dass die Spiritualität zum Lebensende hin eine wichtigere Rolle einnimmt als zuvor. ...
  • Guðmundsdóttir, Kristín; Sigurðardóttir, Zuilma Gabriela; Ala'i-Rosales, Shahla (American Psychological Association (APA), 2017-04)

  • Sigurdardottir, Heida Maria; Jozranjbar, Bahareh (Springer International Publishing, 2019)
    Face recognition is an essential skill that in many species is associated with apparently specialized neurological and cognitive mechanisms. This chapter summarizes some of the behavioral and neuroscientific research on laterality effects in face ...
