Visual Perception Supports Adults in Numerosity Processing and Arithmetical Performance
Frontiers in Psychology, 2021 Previous studies have found a correlation between numerosity processing and arithmetical performance. Visual perception has already been indicated as the shared cognitive mechanism between these two; however, these studies mostly focused on children.

Aging and Numerosity Estimation [PDF]
The Journals of Gerontology: Series B, 2007 Abstract In two experiments, young and older participants were asked to find the approximate number of dots in collections including between 40 and 460 dots. Experiment 1 showed that both age groups had comparable performance and no age-related differences in the power-function exponents for numerosity.

Numerosities are not ersatz numbers
Behavioral and Brain Sciences, 2021 Abstract In describing numerosity as “a kind of ersatz number,” Clarke and Beck fail to consider a familiar and compelling definition of numerosity, which conceptualizes numerosity as the cognitive counterpart of the mathematical concept of cardinality; numerosity is the magnitude, whereas number is a scale through which numerosity/cardinality is ...

Scientific Data, 2023 The ability to handle non-symbolic numerosity has been recurrently linked to mathematical abilities. The accumulated data provide a rich resource that can reflect the underlying properties (i.e., dot ratio, area, convex hull, perimeters, distance, and ...

iScience, 2023 Summary: Numerosity perception is a fundamental cognitive function in humans and animals. Using an individual difference approach with a comprehensive dataset (N = 249), we performed a voxel-based morphometry analysis to unravel the neuroanatomical ...

Grouping mechanisms in numerosity perception [PDF]
Open Mind, 2020 Enumeration of a dot array is faster and easier if the items form recognizable subgroups. This phenomenon, which has been termed groupitizing, appears in children after one year of formal education and correlates with arithmetic abilities. We formulated and tested the hypothesis that groupitizing reflects an ability to sidestep counting by using ...

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.

Numerosity perception is tuned to salient environmental features
iScience, 2022 Summary: Numerosity perception is a key ability to guide behavior. However, current models propose that number units encode an abstract representation of numerosity regardless of the non-numerical attributes of the stimuli, suggesting rather coarse ...

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).
