Intermodal spatial attention differs between vision and audition: an event-related potential analysis.

Subjects were required to attend to a combination of stimulus modality (vision or audition) and location (left or right). Intermodal attention was measured by comparing event-related potentials (ERPs) to visual and auditory stimuli when the modality was ...

Combining sensory information: mandatory fusion within, but not between, senses.

Humans use multiple sources of sensory information to estimate environmental properties. For example, the eyes and hands both provide relevant information about an objects shape. The eyes estimate shape using binocular disparity, perspective projection, ...

Convergence of visual and tactile shape processing in the human lateral occipital complex.

We have recently demonstrated using fMRI that a region within the human lateral occipital complex (LOC) is activated by objects when either seen or touched. We term this cortical region LOtv for the lateral occipital tactile-visual region. We report here ...

Infant perceptual and conceptual categorization: the roles of static and dynamic stimulus attributes.

Infants categorization of animals and vehicles based on static vs. dynamic attributes of stimuli was investigated in five experiments (N=158) using a categorization habituation-of-looking paradigm. In Experiment 1, 6-month-olds categorized static color ...

Perception onset time during fixations in free viewing.

In this study, we investigated when visual perception begins in fixations. During picture viewing, the picture was degraded at the beginning of selected saccades and changed back to the original after varying intervals. Participants manually responded ...

An oscillatory correlation model of visual motion analysis.

We describe and evaluate a model of motion perception based on the integration of information from two parallel pathways: a motion pathway and a luminance pathway. The motion pathway has two stages. The first stage measures and pools local motion across ...

Eye movements of large populations: II. Deriving regions of interest, coverage, and similarity using fixation maps.

The analysis of eye movement traces (i.e., the patterns of fixations in a search) is more complex than that of such parameters as mean fixation duration, and as a result, previous attempts have focused on a qualitative appraisal of the form of an eye ...

Attention to repeated images on the World-Wide Web: another look at scanpath theory.

The scanpath theory of visual perception was tested using Web pages as visual stimuli. Scanpaths are repetitive sequences of fixations and saccades that occur upon reexposure to a visual stimulus. Since Internet users are exposed to repeated visual ...

Using high frame rate CMOS sensors for three-dimensional eye tracking.

A novel three-dimensional eye tracker is described and its performance evaluated. In contrast to previous devices based on conventional video standards, the present eye tracker is based on programmable CMOS image sensors, interfaced directly to digital ...

A laser-based eye-tracking system.

This paper reports on the development of a new eye-tracking system for noninvasive recording of eye movements. The eye tracker uses a flying-spot laser to selectively image landmarks on the eye and, subsequently, measure horizontal, vertical, and ...
