Adaptation acts directly on the sensory representation of numerosity [PDF]
Scientific ReportsLike most perceptual systems, the perception of numerosity is susceptible to adaptation. However, while adaptation to large numerosities is large and spectacular, obvious on demonstration, adapting to sparse fields (reverse adaptation) causes smaller ...

Numerosity Comparison, Estimation and Proportion Estimation Abilities May Predict Numeracy and Cognitive Reflection in Adults [PDF]
Frontiers in Human Neuroscience, 2021 This study explores whether and how different tasks associated with approximate number system (ANS) ability are related to numeracy and cognitive reflection in adults.

Adaptation to visual numerosity changes neural numerosity selectivity [PDF]
NeuroImage, 2021 Perceiving numerosity, i.e. the set size of a group of items, is an evolutionarily preserved ability found in humans and animals. A useful method to infer the neural underpinnings of a given perceptual property is sensory adaptation.

Numerosity adaptation suppresses early visual responses [PDF]
Communications BiologyHumans and many other animals possess an innate ability to rapidly perceive numerosity: the number of objects in a visual scene. Numerosity perception is influenced by adaptation, whereby previously viewed numerosities affect perception of the current ...

Numerosity Perception and Perceptual Load: Exploring Sex Differences Through Eye-Tracking [PDF]
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 ...

Distinct neural representational geometries of numerosity in early visual and association regions across visual streams [PDF]
Communications BiologyVisual numerosity, traditionally linked to the parietal cortex, is now thought to be represented across a broader cortical network, including early visual and associative areas in both streams.

Hierarchical representations of relative numerical magnitudes in the human frontoparietal cortex [PDF]
Nature CommunicationsThe ability to estimate numerical magnitude is essential for decision-making and is thought to underlie arithmetic skills. In humans, neural populations in the frontoparietal regions are tuned to represent numerosity.

Efficient numerosity estimation under limited time. [PDF]
PLoS Computational BiologyThe ability to rapidly estimate non-symbolic numerical quantities is a well-conserved sense across species with clear evolutionary advantages. However, despite its importance, this sense is surprisingly imprecise and biased, and a formal explanation for ...

The relationship between numerosity perception and mathematics ability in adults: the moderating role of dots number [PDF]
PeerJ, 2021 Background It has been proposed that numerosity perception is the cognitive underpinning of mathematics ability. However, the existence of the association between numerosity perception and mathematics ability is still under debate, especially in adults ...
