Mechanisms for perception of numerosity or texture-density are governed by crowding-like effects.
We have recently provided evidence that the perception of number and texture density is mediated by two independent mechanisms: numerosity mechanisms at relatively low numbers, obeying Weber's law, and texture-density mechanisms at higher numerosities, following a square root law. In this study we investigated whether the switch between the two mechanisms depends on the capacity to segregate in...
متن کاملInfant perception of numerosity.
A multiple habituation paradigm was used to determine whether 10--12-month-old infants were able to discriminate between visual arrays which differed only in their numerosity (2 vs. 3, 3, vs. 4, or 4 vs. 5 items). 96 infants were tested in one of two conditions. In the heterogeneous condition, infants were habituated to a series of slides in which only the number of items remained invariant, wh...
متن کاملPhenomenal Effects of Microelements’ Numerosity on Texture Appearance
This paper describes peculiar qualitative effects occurring in texture appearance, resulting from the manipulation of the amount of textural microelements. Keeping fixed the textural local properties, the increase of microelements’ number produces a texture aspect more homogeneous and denser. Conversely, patterns filled by a small number of elements exhibit a more salient subparts’ articulation...
متن کاملTexture contrast aftereffects are monocular; texture density aftereffects are binocular
Two experiments examined interocular transfer for simple and dynamic aftereffects of density and contrast. Simple aftereffects of texture contrast were shown to be primarily monocular. Texture density aftereffects were shown to be primarily binocular. Similarly, dynamic aftereffects to repeated changes in contrast were found to be completely monocular; those to repeated changes in density were ...
متن کاملNumber, texture and crowding.
A recent study shows that selectivity for numerosity emerges as a natural property in deep networks of hierarchical generative models of visual perception. These results, together with recent conceptualizations of crowding and texture, suggest that the 'sense of number' is a fundamental visual property, independent of texture and seemingly related attributes.
