In the motion-extrapolation hypothesis, the visual system can extrapolate the instantaneous position of a moving object from its past trajectory. The existence of such a mechanism in human vision has been intensely debated. Here, we show compelling perceptual extrapolation of both first- and second-order moving stimuli, the magnitude of which depends on blurring of the visual target. The spatio...

This study investigates the interrelations among role integration–segmentation, role identiWcation, reactions to interruptions, and work–life conXict. Results from a Weld survey of university staV employees suggest that as highly identiWed roles are integrated into other domains, high role integration is related to less negative reactions to interruptions, and employees who integrate work into ...

Nurse Ratched or 'Big Nurse' in Ken Kesey's counter-culture novel One Flew Over the Cuckoo's Nest is one of popular culture's most arresting and memorable images of the nurse. She is, however, deemed to be remarkable primarily for her malice and authoritarianism. This paper argues that such a purely realist reading fails to fully appreciate the significance of the character of Nurse Ratched. A ...

Reviewing consumers' motivations to attend performances in a continuously evolving social and technological context is essential because live concerts generate an important and growing share of revenues for the music industry. Evolving fans' preferences and technological innovations constantly alter the way music is distributed and consumed. In a marketing 3.0 era, what consumers do with music ...

Scientific research is heavily dependent on communication and collaboration. Research does not exist in a bubble; scientific work must be communicated in order to add it to the body of knowledge within a scientific community, so that its members may 'stand on the shoulders of giants' and benefit from all that has come before. The effectiveness of scientific communication is crucial to the pace ...

Experiments are presented showing that visual search for Mueller-Lyer stimuli is based on complete configurations rather than component segments. Segments easily detected in isolation were difficult to detect when embedded in a configuration, indicating preemption by low-level groups. This preemption--which caused stimulus components to become inaccessible to rapid search--was an all-or-nothing...

Recent experiments have provided new clues as to how, in visual perception, three-dimensional depth is signaled and integrated with image motion.

Two experiments are reported that examine the influence of semantic contextual constraints on an individual's ability to use parafoveal visual information. Subjects were presented either a word (reptile) or a row of Xs in foveal vision along with a parafoveal nonword (snckks) centered 2.3 degrees or 5 degrees to the left or right of fixation. The subjects were asked to pronounce the parafoveal ...

We address the problem of simultaneous estimation of scene structure and restoration of images from blurred photometric measurements. In photometric stereo, the structure of an object is determined by using a particular reflectance model (the image irradiance equation) without considering the blurring effect. What we show is that, given arbitrarily blurred observations of a static scene capture...
