Connecting Perceptual Organization To Time Perception
<p>Previous research suggests that the organizational cue, connectedness, can influence time judgments of geometric shapes. The stimuli of those experiments consisted of geometric shapes with lines. In the organized set of stimuli, the lines joined the shapes together, and in the unorganized set of …

Perceptual organization and its influence upon attention
… One of the most fundamental steps in this organizational process lies in the construction of objects. By breaking down our sensory input into objects the mind provides a basis upon which it can begin to scaffold our understanding of the world. This thesis therefore explores the basic stages …

Perceptual organization and selective attention: Age-related effects
The research dealing with age-related deficits in driving performance has suggested that changes in visual selective attention are related to changes in driving performance with age. The research reported here seeks to complement past research by investigating age-related changes in facets of …

Learning to see : the early stages of perceptual organization
… common fate motion cues provide a level of perceptual organization which forms the basis for the learning of subsequent cues.

Perceptual Organization in Parkinson’s Disease: A Behavioral Investigation of Basal Ganglia Dysfunction
… exploring the importance of the basal ganglia in perceptual organization (PO) abilities by examining the specific impairments incurred with the damage of such a vital structure is imperative. Therefore, this study attempted to investigate PD performance in tasks in computerized classic gestalt …

Neural correlates of auditory perceptual organization measured with direct cortical recordings in humans
… irrelevant information. How the brain works to perceptually organize the acoustic environment remains unclear despite the multitude of recent studies utilizing microelectrode recordings in experimental animals or non-invasive human neuroimaging. In particular, the role that brain areas outside …

Cognitive grouping in air traffic control
… target tracking tasks have been shown to utilize perceptual organization. This organization has been shown to have both Gestalt features and goal-oriented features. Previous studies have attempted to use memory recall techniques to examine potential cognitive groupings in air traffic control …

A Comparison of Intellectual Test Performance Across Native American and European American Children
… the two groups on Performance IQ or, on the Perceptual Organization Index, Significant scoring differences were also not evident on the Coding, Picture Arrangement, Arithmetic, Block Design, Vocabulary-, Object Assembly and Comprehension subtests. Significant scoring differences were found …

Listening with generative models
… auditory scene synthesis model to address the perceptual organization of sound into sources and events. We aimed to bridge between classical auditory scene analysis phenomena and everyday sounds, asking whether common generative principles could explain auditory scene analysis in both cases. We …

Effects of early and delayed visual experience on intersensory functioning in bobwhite quail chicks
… role of timing of sensory experience in early perceptual organization.

The role of texture in auditory scene analysis
… system must separate the mixture into coherent perceptual representations that are likely to correspond to the underlying sources in the world. This process is known as auditory scene analysis. Although a rich body of work has probed auditory scene analysis with simple synthetic stimuli and …

GPU Accelerated Refined Tensor Voting
… The Tensor Voting algorithm offers a robust perceptual organization and feature extraction solution by leveraging geometric and contextual information. However, its high computational complexity has limited its adoption in many cases. Tensors do not always fall within what the original …

PERCEPTUAL REPRESENTATION OF SPEAKER GENDER
… analyses were used to ascertain listeners’ perceptual organization of speakers. Cluster solutions for listeners’ categorizations of general similarity revealed a complex hierarchical structure in which speakers were broadly differentiated based on gender prototypicality, and more finely …

Structured representations in visual working memory
… computational model that formalizes the roles of perceptual organization and the encoding of summary statistics in visual working memory, and provides a way to quantify capacity even in the presence of richer, more structured memory representations. This formal framework predicts how well …

The Discovery of perceptual structure from visual co-occurrences in space and time
… structures? In this thesis I argue that perceptual organization reflects statistical regularities in the environment. When visual primitives occur together much more often than one would expect by chance, we may learn to associate those primitives and to form a perceptual group. The first …

Neuropsychological and adaptive skills deficits in children with attention-deficit/hyperactivity disorder with and without comorbid fetal alcohol spectrum disorder
… significant deficiencies in verbal ability and perceptual organization whereas children with ADHD/FASD have shown impairment in all of these cognitive abilities. When compared to typically developing children with approximately the same level of general intelligence, children with ADHD have been …
