    The field of lower limb prosthetics has advanced rapidly in the past two decades with increasingly sophisticated devices becoming available each year. Nevertheless, function has yet to be fully restored for people with lower limb amputation. Active ...

    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 ...

    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 ...

    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, ...

    The small-scale study presented here was the first test of three instruments in a sample of Icelandic children: IS-FORM, IS-PSEUDO, and the Strengths and Weaknesses of ADHD-symptoms and Normal-behavior (SWAN) rating scale. Participants in this study ...

    While tactile acuity for pressure has been extensively investigated, far less is known about acuity for vibrotactile stimulation. Vibrotactile acuity is important however, as such stimulation is used in many applications, including sensory substitution ...
  • Guðmundsdóttir, Kristín (University of Iceland, School of Health Sciences, Faculty of Psychology, 2018-12)
    Ágrip Bakgrunnur og meginmarkmið: Markviss og snemmtæk atferlisíhlutun er gagnreynd aðferð sem mælt er með við íhlutun barna með einhverfu og skyldar þroskaraskanir. Hins vegar njóta ekki öll börn og fjölskyldur þeirra slíkrar íhlutunar né þeirrar ...
  • Stefánsson, Kristján K. (Univeristy of Iceland, 2017-05)
    The importance of school engagement (i.e., the willingness to engage in learning) for school success, such as good academic achievement and low dropout rates, has been well established. At the same time, intentional selfregulation (ISR; i.e., the ...

    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, ...

    Background Every year a substantial number of children are affected by natural disasters worldwide. However, data are scarce on long-term psychological impact of natural disasters on children's health. Identifying risk factors and outcomes associated ...

    The key characteristic of a traumatic event as defined by the Diagnostic and Mental Manual of Mental Disorders (DSM) seems to be a threat to life. However, evidence suggests that other types of threats may play a role in the development of PTSD and ...
