Numerosity Perception in Peripheral Vision [PDF]
Frontiers in Human Neuroscience, 2021 Peripheral vision has different functional priorities for mammals than foveal vision. One of its roles is to monitor the environment while central vision is focused on the current task.

The specious interaction of time and numerosity perception [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2021 Magnitude information is essential to create a representation of the external environment and successfully interact with it. Duration and numerosity, for example, can shape our predictions and bias each other (i.e. the greater the number of people queuing, the longer we expect to wait).

Grouping Mechanisms in Numerosity Perception [PDF]
Open Mind, 2021 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 perception is tuned to salient environmental features [PDF]
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 ...

Quantum spin models for numerosity perception. [PDF]
PLoS One, 2023 Humans share with animals, both vertebrates and invertebrates, the capacity to sense the number of items in their environment already at birth. The pervasiveness of this skill across the animal kingdom suggests that it should emerge in very simple populations of neurons.

Feature-selective adaptation of numerosity perception [PDF]
Proceedings of the Royal Society B: Biological SciencesPerceptual adaptation has been widely used to infer the existence of numerosity detectors, enabling animals to quickly estimate the number of objects in a scene. Here, we investigated, in humans, whether numerosity adaptation is influenced by stimulus feature changes as previous research suggested that adaptation is reduced when the colour of adapting ...

Topology-defined units in numerosity perception [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2015 Significance What is a number? The answer to this age-old and fundamental question of philosophy has increasingly benefited from recent scientific investigation using psychology and neuroscience. To verify the invariant nature of numerosity perception, we manipulated the numbers of items connected/enclosed in arbitrary and irregular forms ...

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 ...

Symmetry as a grouping cue for numerosity perception. [PDF]
Sci Rep, 2022 AbstractTo 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. In the current study, we investigated how symmetry affects the ability to rapidly estimate the number of objects (numerosity).

EEG signature of grouping strategies in numerosity perception. [PDF]
Front Neurosci, 2023 The moment we see a group of objects, we can appreciate its numerosity. Our numerical estimates can be imprecise for large sets (>4 items), but they become much faster and more accurate if items are clustered into groups compared to when they are randomly displaced.
