During self-motion, the world normally appears stationary. In part, this may be due to
reductions in visual motion signals during self-motion. In 8 experiments, the authors used …

We address the challenges of how to model human perceptual grouping in random dot
arrays and how perceptual grouping affects human number estimation in these arrays. We …

Humans and other species have perceptual mechanisms dedicated to estimating
approximate quantity: a sense of number. Here we show a clear interaction between self …

Behavioral studies of numerical cognition have shown that perceptual threshold for
numerosity discrimination depends on the range of numerical values to be estimated …

While recent studies in adults have demonstrated the existence of a neural mechanism for a
visual sense of number, little is known about its development and whether such a …

Considerable recent work suggests that mathematical abilities in children correlate with the
ability to estimate numerosity. Does math correlate only with numerosity estimation, or also …

While observers are adept at judging the density of elements (eg, in a random-dot image), it
has recently been proposed that they also have an independent visual sense of number. To …

Adult number representations can belong to either of two types. One is discrete, language-
specific, and culturally-derived; the other is analog and language-independent. Quantitative …

Background Recent studies have demonstrated that fish display rudimentary numerical
abilities similar to those observed in mammals and birds. The mechanisms underlying the …

It has been claimed that a genuinely abstract numerical representation would be capable of
representing the numerosity of any set of discrete elements independently of the attributes of …
