Hemispheric Effects of Response Hand and Concurrent Auditory and Visual Information Processing on Task Performance
… "integrity" between the hemisphere of information input, processing, and motor response. This task-hemispheric integrity has been found to exist during concurrent performance of verbal and spatial tasks, both of which are presented in a visual modality. The present study sought to …

Visual Information Processing of Geometric Figures as a Function of Complexity and Field of Vision
… of this study was to investigate whether human information processing does occur in parallel in the right hemisphere and serially in the left hemisphere as suggested by the hemisphere strategy model. In addition, this study was also designed to determine if there is a right hemisphere advantage …

Effects of Nicotine Pharmacology and Stimulus Expectancies on Withdrawal and Attentional Processing
… Wisconsin Smoking Withdrawal Scale and the Rapid Visual Information Processing task. This design created four groups of participants split by instructional set (told high-dose nicotine cigarette vs. told low-dose nicotine cigarette) and actual nicotine dose (low-dose vs. high-dose). For subjective …

Selective Attention: Noise Suppression and Signal Enhancement
Whether visual selective attention is manifested under display conditions containing no competing or irrelevant noise elements has become a topic of increasingly widespread interest in visual information processing. The results of many early detection studies suggest that attention is the filtering …

An informatics system for exploring eye movements in reading
… these researchers to design experiments, present visual stimuli and process the large quantity of numerical data produced by the eye tracker. However, most applications, especially commercial products, are designed for a particular tracking device and tend to be general purpose. Few of them are …

Lokalisation sukzessiv präsentierter Reize : Interaktion räumlicher Aufmerksamkeit und lokaler Verarbeitungsmechanismen
… regions. However, the spatial resolution of the visual system could be distorted by psychophysical variables as eccentricity or successive presentation of stimuli. This study deals with a perceptual error which is influenced by both factors. The clarification of this error should contribute to …

Visual attention shifting in autism spectrum disorder
… spectrum disorders (ASD). Abnormalities in visual attention are particularly notable in ASD and have the potential to inform an understanding of the aberrant neural networks underlying this disorder. The current study utilized a model integrating components of both a two-stage model of …

Toward a more biologically plausible model of object recognition
… and the first few hundred milliseconds of visual information processing in the ventral pathway of the primate visual cortex. There are three major contributions. First, the two main operations in the model (Gaussian and maximum) have been cast into a more biologically plausible form, using …

Characterization Of High-Voltage-Activated Calcium Channels In Retinal Bipolar Cells
<p>Retinal bipolar cells, conveying visual information from photoreceptors to ganglion cells, segregate visual information into multiple parallel pathways through their diversified cell types and physiological properties. Voltage-gated Ca<sup>2+</sup> channels could be particularly important …

Case Studies in Invertebrate Visual Processing: I. Spectral and Spatial Processing in the Early Visual System of Drosophila melanogaster II. Binocular Stereopsis in Sepia officinalis
This thesis addresses two aspects of visual processing in two different invertebrate organisms. The fruit fly, Drosophila melanogaster, has emerged as a key model for invertebrate vision research. Despite extensive characterisation of motion vision, very little is known about how flies process …
