Number and density discrimination rely on a common metric: Similar psychophysical effects of size, contrast, and divided attention.
While observers are adept at judging the density of elements (e.g., in a random-dot image), it has recently been proposed that they also have an independent visual sense of number. To test the independence of number and density discrimination, we examined the effects of manipulating stimulus structure (patch size, element size, contrast, and contrast-polarity) and available attentional resource...
متن کاملA common visual metric for approximate number and density.
There is considerable interest in how humans estimate the number of objects in a scene in the context of an extensive literature on how we estimate the density (i.e., spacing) of objects. Here, we show that our sense of number and our sense of density are intertwined. Presented with two patches, observers found it more difficult to spot differences in either density or numerosity when those pat...
متن کاملPsychophysical evidence for the number sense
It is now clear that most animals, including humans, possess an ability to rapidly estimate number. Some have questioned whether this ability arises from dedicated numerosity mechanisms, or is derived indirectly from judgements of density or other attributes. We describe a series of psychophysical experiments, largely using adaptation techniques, which demonstrate clearly the existence of a num...
متن کاملMetric Learning with Adaptive Density Discrimination
Distance metric learning (DML) approaches learn a transformation to a representation space where distance is in correspondence with a predefined notion of similarity. While such models offer a number of compelling benefits, it has been difficult for these to compete with modern classification algorithms in performance and even in feature extraction. In this work, we propose a novel approach exp...
متن کاملPsychophysical evidence for a radial motion bias in complex motion discrimination
In a graded motion pattern task we measured observers' ability to discriminate small changes in the global direction of complex motion patterns. Performance varied systematically as a function of the test motion (radial, circular, or spiral) with thresholds for radial motions significantly lower than for circular motions. Thresholds for spiral motions were intermediate. In all cases thresholds ...
