(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 ... -
(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, ...
-
(IOS Press, 2016-09-21)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 ...
-
(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 ...
-
(Springer Nature, 2018-01-23)People often miss salient events that occur right in front of them. This phenomenon, known as change blindness, reveals the limits of visual awareness. Here, we investigate the role of implicit processing in change blindness using an approach that ...
-
(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 ...
-
(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 ...
-
(Springer Nature, 2017-04-04)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 ...
-
(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 ...
-
(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, ...
-
(Springer Nature, 2017-08-30)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 ...
-
(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 ...
-
(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. ...
-
(Public Library of Science (PLoS), 2019-07-25)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, ...
-
(MDPI AG, 2016-06-27)The Sound of Vision project involves developing a sensory substitution device that is aimed at creating and conveying a rich auditory representation of the surrounding environment to the visually impaired. However, the feasibility of such an approach ...
-
(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 ...
