The way the cognitive system scans the visual environment for relevant information–visual
search in short–has been a long-standing central topic in vision science. From its inception …

To investigate how tactile and proprioceptive information are used in haptic object
discrimination we conducted a haptic search task in which participants had to search for …

We conducted a haptic search experiment to investigate the influence of the Gestalt
principles of proximity, similarity, and good continuation. We expected faster search when …

It remains controversial whether using two hands and multiple fingers provides any
perceptual advantage over a single index finger. The present study examines this long …

Numerosity judgments of small sets of items (≤ 3) are generally fast and errorfree, while
response times and error rates increase rapidly for larger numbers of items. We investigated …

We proposed to abandon the item as conceptual unit in visual search and adopt a fixation-
based framework instead. We treat various themes raised by our commentators, including …

We investigated the applicability of the Gestalt principle of perceptual grouping by proximity
in the haptic modality. To do so, we investigated the influence of element proximity on haptic …

We used a haptic enumeration task to investigate whether enumeration can be facilitated by
perceptual grouping in the haptic modality. Eight participants were asked to count tangible …

When performing everyday tasks, we often move our eyes and hand together: we look
where we are reaching in order to better guide the hand. This coordinated pattern with the …

Much of the evidence for theories in visual search (including Hulleman & Olivers'[H&O's])
comes from inferences made using changes in mean RT as a function of the number of …
