The thesis of this article is that, in the drawings of very young children, line is produced as a path before it is produced as a boundary. An explanation for this progression is proposed. (Author/JMB)

In three studies of infants' ability to perceive partially occluded objects with specific appearances, a screen alternately uncovered and covered either a connected or interrupted rectangle. Pattern of infants' looking times suggests that they perceive the unity of the partially occluded object by 6.5 months but did not perceive the form of the…

Assessed infants' and adults' adjustment of hand orientation before grasping objects. Found that infants modified their hand orientation to match the long axis of an object, did not make anticipatory hand adjustments before reaching through a narrow aperture to grasp an object, and oriented their hand to be parallel with the handle of an object.…

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…
