    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 ...

    Grapheme-color synesthesia is a condition where the perception of graphemes consistently and automatically evokes an experience of non-physical color. Many have studied how synesthesia affects the processing of achromatic graphemes, but less is known ...

    Early-life risk factors, such as family disruption, maltreatment, and poverty, can negatively impact children's scholastic abilities; however, most previous studies have relied on cross-sectional designs and retrospective measurement. This study ...

    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 ...
  • 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 ...

    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)
    This article describes the development and results of behavioral training via telecommunication for three caregivers of children with autism. A single-subject, multiple baseline experimental design, replicated across caregivers, preschool children with ...

    Background: More than 500 million people worldwide live within exposure range of an active volcano and children are a vulnerable subgroup of such exposed populations. However, studies on the effects of volcanic eruptions on children’s health beyond the ...
  • Jónsdóttir, Sigrídur Lóa; Brynjarsdóttir, Birta; Sæmundsen, Evald E.; Sigurðsson, Jón Friðrik (Exeley, Inc., 2018)
    Background: Studies on early intervention have reported significant gains for many children with autism. Knowledge on how these children fare in adulthood is limited. Objective: To examine long-term outcome of children with autism who received ...
  • Hoffmann, Rebekka; Valgeirsdóttir, Vigdís Vala; Jóhannesson, Ómar I.; Unnthorsson, Runar; Kristjansson, Arni (Springer Nature, 2018-10-06)
    Vibrotactile displays can compensate for the loss of sensory function of people with permanent or temporary deficiencies in vision, hearing, or balance, and can augment the immersive experience in virtual environments for entertainment, or professional ...
  • Sigurdardottir, Heida Maria; Hjartarson, Kristján Helgi; Guðmundsson, Guðbjörn Lárus; Kristjansson, Arni (Elsevier BV, 2019-05)
    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 ...

    We use polygenic risk scores (PRSs) for schizophrenia (SCZ) and bipolar disorder (BPD) to predict smoking, and addiction to nicotine, alcohol or drugs in individuals not diagnosed with psychotic disorders. Using PRSs for 144 609 subjects, including 10 ...

    Background Hypertensive disorders complicate up to 10% of pregnancies. Evidence suggests a potential association between maternal hypertensive disorders during pregnancy, particularly preeclampsia, and adverse neurodevelopment in the offspring, but ...

    Previous research shows that dyslexic readers are impaired in their recognition of faces and other complex objects, and show hypoactivation in ventral visual stream regions that support word and object recognition. Responses of these brain regions ...

    Many environmental problems stem from unsustainable human consumption. Accordingly, many studies have focused on the barriers to pro-environmental behavior. The inability or unwillingness to act is partially related to personal values as well as the ...
  • 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, ...
