Out of all the human senses, touch is the one that is most often unappreciated, and
undervalued. Yet, the surface of the human body, the skin, is actually one huge sheet of …

Research in cognitive psychology has focused mainly on the visual modality as the input
interface for mental processes. We suggest that integrating studies from different modalities …

The last decade has seen a rapid growth in our understanding of the cognitive systems that
underlie mathematical learning and performance, and an increased recognition of the …

Small quantities of visual objects can be rapidly estimated without error, a phenomenon
known as subitizing. Larger quantities can also be rapidly estimated, but with error, and the …

Dedicated maps for cognitive quantities such as timing, size and numerosity support the
view that topography is a general principle of brain organization. To date, however, all of …

Subitizing is a fast and accurate enumeration process of small sets of usually less than four
objects. Several models were proposed in the literature. Critically, only pattern recognition …

Groupitizing is a recently described phenomenon of numerosity perception where clustering
items of a set into smaller “subitizable” groups improves discrimination. Groupitizing is …

Advances in tactile cognition and haptics have increased our understanding of the
multimodal nature of touch. Haptic data is mostly confined to human performance arising …

Our study explores various aspects of enumerating small quantities in the tactile modality.
Fingertips of one hand were stimulated by a vibro-tactile apparatus (for 100/800 ms) …

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 …
