Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Reaching for objects, walking without hitting obstacles, landing on a chair as you sit (instead of falling to the floor), these and all our physical actions depend on an ability to perceive our own bodies in space, to know where our limbs are relative to one another and relative to the rest of the world. One way that the human brain encodes this information is called proprioception, the brain relies on its own control and feedback...

We demonstrate how an objective measure can be employed in the widely employed rubber hand illusion paradigm. This measure is obtained by modifying the well-established crossmodal congruency task. This task allows the investigation of multisensory processes which are critical for modulations of body representations as in the rubber hand illusion.

Here we present a Ground Penetrating Radar (GPR) system based on a ground-coupled, densely populated antenna array for monitoring the dynamic process of subsurface water infiltration. A time-lapse radar image of the infiltration process allowed estimating the depth of the wetting front during the course of the infiltration process.

Liquid Phase Reactor: Sucrose Inversion

Source: Kerry M. Dooley and Michael G. Benton, Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA Both batch and continuous flow reactors are used in catalytic reactions. Packed beds, which use solid catalysts and a continuous flow, are the most common configuration. In the absence of an extensive recycle stream, such packed bed reactors are typically modeled as "plug flow". The other most common continuous reactor is a stirred tank, which is assumed to be perfectly...
FAQs
Familiar-object expectations provide the visual system with a strong prediction about likely shape. When shading, perspective, and apparent contours support that prediction, the brain may interpret conflicting geometric information according to the expected object rather than its actual surface orientation. This makes the illusion useful for examining how prior knowledge guides perceptual interpretation.
Monocular cues remain available from a single viewpoint and can strongly suggest a particular three-dimensional shape through shading, perspective, and surface contours. Binocular disparity may indicate a different depth arrangement, yet the combined monocular pattern can dominate perception. The resulting conflict reveals that depth perception depends on weighted evidence, not on binocular information alone.
The phenomenon shows that perceived shape is constructed by integrating sensory signals with expectations rather than copied directly from physical geometry. Ambiguous images can therefore produce a stable but incorrect interpretation of surface depth. In behavior research, this provides a way to examine how the visual system resolves disagreement among cues during ordinary perception.
Attention is relevant because observers may selectively process different aspects of an ambiguous image, including familiar-object structure, shading, perspective, or apparent contours. Studying the illusion alongside attention research can clarify whether perceptual interpretation changes when observers focus on particular visual information. This connects depth inversion with broader questions about how attention shapes visual experience.
Researchers can present ambiguous three-dimensional objects or images and examine how observers interpret their surface orientation and depth. The key comparison concerns perceived shape versus the object’s actual geometry, especially when monocular cues conflict with binocular disparity. Such observations help characterize the influence of prior knowledge and sensory integration on visual judgments.
The illusion offers a framework for studying unusual or altered depth perception in visual disorders by showing how competing cues are combined. In virtual reality and computer-generated displays, the same principles can guide designs that manipulate perceived depth through shading, perspective, contours, or disparity. These applications connect perceptual research with both clinical investigation and display development.
