  • 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 ...
  • Rafiei, Mohsen (University of Iceland, School of Health Sciences, Faculty of Psychology, 2021-12-10)
    Our eyes are the primary gates to the visible world around us. Yet, whatever we perceive involves a translation of the patterns of the photons hitting our retinas into mental representations. It could be argued that visual perception is merely an ...
  • 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, ...
  • Tanrikulu, Ömer Daglar; Chetverikov, Andrey; Kristjánsson, Árni (2020)
    Observers can learn complex statistical properties of visual ensembles, such as their probability distributions. Even though ensemble encoding is considered critical for peripheral vision, whether observers learn such distributions in the periphery has ...
  • Thornton, Ian M.; Tagu, Jérôme; Zdravković, Sunčica; Kristjánsson, Árni (2021-05-06)
    Attention is known to play an important role in shaping the behaviour of both human and animal foragers. Here, in three experiments, we built on previous interactive tasks to create an online foraging game for studying divided attention in human ...
  • Ásgeirsson, Árni; Kristjansson, Arni (Frontiers Media SA, 2014-04-10)
    Consistent financial reward of particular features influences the allocation of visual attention in many ways. More surprising are 1-trial reward priming effects on attention where reward schedules are random and reward on one trial influences attentional ...
  • Brinkhuis, M. A. B.; Kristjansson, Arni; Harvey, Ben M; Brascamp, Jan W (Oxford University Press (OUP), 2019-11-07)
    Priming of attention shifts involves the reduction in search RTs that occurs when target location or target features repeat. We used functional magnetic resonance imaging to investigate the neural basis of such attentional priming, specifically focusing ...
