    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, ...

    Introduction: Patients with diabetes and diabetic peripheral neuropathy (DPN) place their feet with less accuracy whilst walking, which may contribute to the increased falls-risk. This study examines the effects of a multi-faceted intervention on ...

    Both intact and deficient neural processing of faces has been found in dyslexic readers. Similarly, behavioral studies have shown both normal and abnormal face processing in developmental dyslexia. We tested whether dyslexic adults are impaired in tests ...
  • 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 ...
  • Chetverikov, Andrey; Campana, Gianluca; Kristjansson, Arni (Association for Research in Vision and Ophthalmology (ARVO), 2017-02-28)
    We recently demonstrated that observers are capable of encoding not only summary statistics, such as mean and variance of stimulus ensembles, but also the shape of the ensembles. Here, for the first time, we show the learning dynamics of this process, ...
  • Hansmann-Roth, Sabrina; Chetverikov, Andrey; Kristjansson, Arni (Association for Research in Vision and Ophthalmology (ARVO), 2019-08-01)
    Objects have a variety of different features that can be represented as probability distributions. Recent findings show that in addition to mean and variance, the visual system can also encode the shape of feature distributions for features like color ...
  • Manassi, Mauro; Kristjansson, Arni; Whitney, David (Springer Science and Business Media LLC, 2019-12-01)
    In everyday life, we continuously search for and classify objects in the environment around us. This kind of visual search is extremely important when performed by radiologists in cancer image interpretation and officers in airport security screening. ...

    Traditional search tasks have taught us much about vision and attention. Recently, several groups have begun to use multiple-target search to explore more complex and temporally extended “foraging” behaviour. Many of these new foraging tasks, however, ...
  • 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 ...

    We describe the Multilanguage Written Picture Naming Dataset. This gives trial-level data and time and agreement norms for written naming of the 260 pictures of everyday objects that compose the colorized Snodgrass and Vanderwart picture set (Rossion ...
