The impact of emotion on numerosity estimation [PDF]
Frontiers in Psychology, 2013 Both time and numerosity can be represented continuously as analog properties whose discrimination conforms to Weber’s Law, suggesting that the two properties may be represented similarly.

Symmetry as a grouping cue for numerosity perception
Scientific Reports, 2022 To estimate the number of objects in an image, each element needs to be segregated as a single unit. Several principles guide the process of element identification, one of the strongest being symmetry.

The numerosity and mean size of multiple objects are perceived independently and in parallel. [PDF]
PLoS ONE, 2017 It is well documented that people are good at the rapid representation of multiple objects in the form of ensemble summary statistics of different types (numerosity, the average feature, the variance of features, etc.).

Non-Numerical Methods of Assessing Numerosity and the Existence of the Number Sense
Journal of Numerical Cognition, 2023 In the literature on numerical cognition, the presence of the capacity to distinguish between numerosities by attending to the number of items, rather than continuous properties of stimuli that correlate with it, is commonly taken as sufficient ...

Numerosity Perception and Perceptual Load: Exploring Sex Differences Through Eye-Tracking
Journal of Eye Movement ResearchThis study investigates sex differences in numerosity perception and visuospatial abilities in adults using eye-tracking methodology. We report the results of a controlled dual-task experiment that assessed the participants’ visuospatial and numerosity ...

Frontiers in Computational Neuroscience, 2009 Humans and animals are known to share an ability to estimate or compare the numerosity of visual stimuli, and this ability is considered to be supported by the cortical neurons that have unimodal tuning for numerosity, referred to as the numerosity ...

Autistic individuals show less grouping-induced bias in numerosity judgments
Frontiers in Child and Adolescent Psychiatry, 2023 IntroductionWhen items are connected together, they tend to be perceived as an integrated whole rather than as individual dots, causing a strong underestimation of the numerosity of the ensemble. Previous evidence on grouping-induced biases of numerosity

The Grouping-Induced Numerosity Illusion Is Attention-Dependent
Frontiers in Human Neuroscience, 2021 Perceptual grouping and visual attention are two mechanisms that help to segregate visual input into meaningful objects. Here we report how perceptual grouping, which affects perceived numerosity, is reduced when visual attention is engaged in a ...

Near-optimal integration of the magnitude information of time and numerosity
Royal Society Open Science, 2023 Magnitude information is often correlated in the external world, providing complementary information about the environment. As if to reflect this relationship, the perceptions of different magnitudes (e.g.

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.
