Explores a range of vocal and visual practices deployed by Japanese speakers during the course of a word search in naturally occurring conversation and shows how such embodied practices provide publicly available resources for recipients to organize their relevant participation in the ongoing word search.

Discusses access to digitized images in information retrieval and cognitive engagement with viewed images. Describes an investigation that looked at how users view images in relation to how they can be described, or categorized, and in what manner they match other images in the same collection.

First, newborns' preferential looking between pairs of stimuli which varied in real size and viewing distance was solely determined by retinal size. Second, newborns desensitized to changes in distance and retinal size strongly preferred an object of a different size to the familiar one. (RH)

Two studies examined whether individual faces are perceived categorically. A linear continuum of "morphed" faces was generated between individual exemplars of familiar faces. Subjects, undergraduate students, discriminated most accurately when face-pairs straddled apparent category boundaries; thus individual faces are perceived…

Eight experiments, each with 10 observers in each condition, show that the visual search for Mueller-Lyer stimuli is based on complete configurations rather than component segments with preemption by low-level groups. Results support the view that rapid visual search can only access higher level, more ecologically relevant structures. (SLD)

It is argued that a reflectance channel that requires priority information is shown to be less plausible for the human visual system than J. L. Dannemiller (1989) argued. In the response, Dannemiller replies that lightness is not an illuminant invariant surface descriptor when daylight illuminant substitutions are considered. (SLD)

Prison inmates (n=72) were screened for scotopic sensitivity syndrome (SSS), a visual perceptual dysfunction; 11% had low levels of SSS, 18.1% moderate, and 79.8% high, compared with 12-14% of the general population. Remedial colored overlays improved reading considerably for 55.6%, moderately for 33.3%. (SK)

Examined relationship between visual organization, perceptual closure, and compulsive-like behaviors in 3- to 6-year-olds. Found that children's performance on visual organization and perceptual-closure tasks were significantly related to compulsive-like behaviors reported by parents, and these associations were mediated by mental age. Results…

In this article, the author states that architects, musicians and other thoughtful people have, since the time of Pythagoras, been fascinated by various harmonious proportions. One, is the visual harmony attributed to Euclid, called "the golden section". He explores this concept in geometries of one, two and three dimensions. He added,…

In 2 experiments, the authors examined how characteristics of a simulated traffic environment and in-vehicle tasks impact driver performance and visual scanning and the extent to which a computational model of visual attention (SEEV model) could predict scanning behavior. In Experiment 1, the authors manipulated task-relevant information bandwidth…

The purpose of the present study was to identify differences between cerebral hemispheres for processing temporal intervals ranging from .9 to 1.4s. The intervals to be judged were marked by series of brief visual signals located in the left or the right visual field. Series of three (two standards and one comparison) or five intervals (four…

Controlling a hand-held tool requires that the tool user bring the tool into contact with an environmental surface in a task-appropriate manner. This, in turn, requires applying muscular forces so as to overcome how the object resists being moved about its various axes. Perceived properties of hand-held objects tend to be constrained by inertial…

The authors used counterpredictive cues to examine reflexive and volitional orienting to eyes and arrows. Experiment 1 investigated the effects of eyes with a novel design that allowed for a comparison of gazed-at (cued) target locations and likely (predicted) target locations against baseline locations that were not cued and not predicted.…

F. Attneave (1954) famously suggested that information along visual contours is concentrated in regions of high magnitude of curvature, rather than being distributed uniformly along the contour. Here the authors give a formal derivation of this claim, yielding an exact expression for information, in C. Shannon's (1948) sense, as a function of…

In the present study, 9-, 12- and 16-month-old infants were familiarized to a block that was repeatedly lowered into a container and lifted from that container again. In the subsequent test phase, the block passed through the container opening either without making contact with the container rim or colliding with the rim in three places but…
