Perceptual organization, visual attention, and objecthood
We have previously demonstrated that the mere organization of some elements in the visual field into an object attracts attention automatically. Here, we explored three different aspects of this automatic attentional capture: (a) Does the attentional capture by an object involve a spatial component? (b) Which Gestalt organization factors suffice for an object to capture attention? (c) Does the ...
متن کاملFrom Gibson’s Fire to Gestalts: A bridge-building theory of perceptual objecthood
Two kinds of rifts separate perceptual researchers: theoretical and modality-specific. Theoretical rifts divide modality-specific communities, and modality-specific rifts divide theoretical communities. Each group seeks to understand perception, but each uses such different approaches that synthesis into one coherent theory has been impossible. Here, we examine the fissures and propose a theory...
متن کاملObjecthood: an Event Structure Perspective
The notion 'object' 1 has proved useful in the description of grammatical phenomena in and across languages as it picks out a set of noun phrases characterized by a convergence of what Keenan (1976) calls behavioral and coding properties. Concomitantly, this notion has even been taken as a primitive within certain approaches to linguistic representation (e.g. Relational Grammar, Lexical Functio...
متن کاملCosts and benefits in perceptual categorization.
Observers categorized perceptual stimuli when the category costs and benefits were manipulated across conditions, and costs were either zero or nonzero. The cost-benefit structures were selected so that performance across conditions was equivalent with respect to the optimal classifier. Each observer completed several blocks of trials in each of the experimental conditions, and a series of nest...
متن کاملThe Effect of Objecthood on Processing Efficiency
The term objecthood is used to convey the degree of image regularity in terms of properties such as closure, symmetry and parallelism. The notion of objecthood is evaluated in the light of the existing psychological data on sensory-driven biases of attentional selection. Extending the biased competition for selection framework, we tested if higher objecthood of the image modulates its salience ...
