Proximity model of perceived numerosity
Attention, Perception, & Psychophysics, 2021The occupancy model (OM) was proposed to explain how the spatial arrangement of dots in sparse random patterns affects their perceived numerosity. The model's central thesis maintained that each dot seemingly fills or occupies its surrounding area within a fixed radius ro and the total area collectively occupied by all the dots determines their ...

Numerosity-Length Interference
Experimental Psychology, 2007Abstract. The existence of a common mechanism for length and numerosity processing was tested with a Stroop task. Participants compared the length or the numerosity of arrays of dots, for which the two variables were manipulated independently to create congruent, incongruent, or neutral pairs.

Numerosity discrimination: Infants discriminate small from large numerosities
European Journal of Developmental Psychology, 2006Two experiments investigated numerosity discrimination in 7-month-old infants, comparing their performance on numbers within the range of subitizing (2 and 3 elements) with numbers marking the limit of this range, 4 elements, or lying outside this range (5 and 6 elements).

Interactions between area and numerosity
Psychological Research, 1988The concept of filled area, i.e. the impressionistic ensemble of parts of a stimulus field occupied by dots, is used to account for various kinds of numerosity illusions due to perceptual interaction between a number of dots and their spatial arrangement.

Abstract Clarke and Beck (C&B) assume that approximate number system (ANS) representations should be assigned referents from our scientific ontology. However, many representations, both in perception and cognition, do not straightforwardly refer to such entities.

Numerosity Discrimination of Tactile Stimuli
Perceptual and Motor Skills, 1976The ability of 40 college students to discriminate the number of tactile stimuli presented simultaneously was measured in two experiments. Stimulation was provided by 12 solenoids fixed to points on the arms and legs. Exp. I showed a mean correct discrimination level of between 1.55 and 2.10 solenoids. Exp.

Statistical regularities reduce perceived numerosity
Cognition, 2016Numerical information can be perceived at multiple levels (e.g., one bird, or a flock of birds). The level of input has typically been defined by explicit grouping cues, such as contours or connecting lines. Here we examine how regularities of object co-occurrences shape numerosity perception in the absence of explicit grouping cues.

Numerosity cognition is a cognitive ability that is not restricted by sensory modalities. It remains unclear whether numerosity processing among different modalities can interact with each other. Here, by using psychophysical methods, EEG techniques, and source localization analysis, we measured neural responses to the interaction between auditory ...

The particulate nature of matter was not evident for a long time in early history. Demokritos (460–370 BC) is mostly credited with the concept of particulate matter, probably based on philosophical grounds. But it was centuries later before the concept was really established by the systematic scientific work of Antoine-Laurent Lavoisier (1743–1794 ...
