Perceptual grouping, not covert attention, drives the connectedness effect in the ANS
A robust finding in numerical cognition is that connecting items within an array leads to systematic underestimation of numerosity. This provides evidence that approximate numerosity perception relies on discrete objects rather than on continuous variables (e.g., total area, density, convex hull). While this connectedness effect is often attributed to perceptual grouping, an alternative interpretation is that connected items may capture covert at…
Sensitivity to Geometric Shape Regularity Emerges Independently of Vision
In a visual intruder task, regular quadrilaterals such as squares and rectangles are easier to process than matched shapes devoid of parallelism, symmetry or right-angles. This geometric regularity effect was found in various human groups, including preschoolers and uneducated adults, but not in non-human primates. It was proposed to reflect a fundamental ability to combine discrete geometric features into structured representations of geometric …
From shape to number
Enumerating a large set of objects (e.g., more than four items) can be accomplished more quickly and/or accurately when the objects are grouped into clusters based on Gestalt principles such as proximity and color similarity, a phenomenon known as “groupitizing.” However, whether other visuospatial features can similarly influence this mechanism remains unclear. This study investigated the impact of a novel feature: shape-from-dots homogeneity. P…
Numerosity adaptation resists filtering
The mechanisms underlying numerosity perception remain debated, with some theories proposing a dedicated system for segmented items and others suggesting reliance on low-level features like spatial-frequency or texture-density. Numerosity adaptation-where exposure to one array alters the perceived numerosity of a subsequent one-has been interpreted as evidence for a numerosity-specific mechanism. However, recent accounts argue that this effect ma…
The influence of self-experienced iconic finger-postures on numerical processing
Number is not just an illusion
While seminal theories suggest that nonsymbolic visual numerosity is mainly extracted from segmented items, more recent views advocate that numerosity cannot be processed independently of nonnumeric continuous features confounded with the numerical set (i.e., such as the density, the convex hull, etc.). To disentangle these accounts, here we employed two different visual illusions presented in isolation or in a merged condition (e.g., combining t…
Spatial frequency equalization does not prevent spatial–numerical associations
There is an intense debate surrounding the origin of spatial–numerical associations (SNAs), according to which small numbers are mapped onto the left side of the space and large numbers onto the right. Despite evidence suggesting that SNAs would emerge as an innate predisposition to map numerical information onto a left-to-right spatially oriented mental representation, alternative accounts have challenged these proposals, maintaining that such a…
