Separate Mechanisms for Perception of Numerosity and Density
Psychological Science, 2013 Despite the existence of much evidence for a number sense in humans, several researchers have questioned whether number is sensed directly or derived indirectly from texture density. Here, we provide clear evidence that numerosity and density judgments are subserved by distinct mechanisms with different psychophysical ...

Brain Sciences, 2022 Many individuals, when faced with mathematical tasks or situations requiring arithmetic skills, experience exaggerated levels of anxiety. Mathematical anxiety (MA), in addition to causing discomfort, can lead to avoidance behaviors and then to ...

Number comparison under the Ebbinghaus illusion
Frontiers in Psychology, 2022 A series of studies show interest in how visual attributes affect the estimate of object numbers in a scene. In comparison tasks, it is suggested that larger patches are perceived as more numerous.

Numerosity estimation in visual stimuli in the absence of luminance-based cues. [PDF]
PLoS ONE, 2011 BackgroundNumerosity estimation is a basic preverbal ability that humans share with many animal species and that is believed to be foundational of numeracy skills.

Motion along the mental number line reveals shared representations for numerosity and space
eLife, 2016 Perception of number and space are tightly intertwined. It has been proposed that this is due to ‘cortical recycling’, where numerosity processing takes over circuits originally processing space.

Groupitizing Improves Estimation of Numerosity of Auditory Sequences
Frontiers in Human Neuroscience, 2021 Groupitizing is a recently described phenomenon of numerosity perception where clustering items of a set into smaller “subitizable” groups improves discrimination.

Perception of visual numerosity in humans and machines
CoRR, 2019 Numerosity perception is foundational to mathematical learning, but its computational bases are strongly debated. Some investigators argue that humans are endowed with a specialized system supporting numerical representation; others argue that visual numerosity is estimated using continuous magnitudes, such as density or area, which usually co-vary ...

The effect of perceptual grouping on haptic numerosity perception [PDF]
Attention, Perception, & Psychophysics, 2014 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 dots as quickly and accurately as possible, while moving their finger pad over a tactile display.

Frontiers in Human Neuroscience, 2021 Humans and other species share a perceptual mechanism dedicated to the representation of approximate quantities that allows to rapidly and reliably estimate the numerosity of a set of objects: an Approximate Number System (ANS).
