P. J. Kellman and T. F. Shipley (1992) and P. J. Kellman, P. Garrigan, and T. F. Shipley (2005) suggested that completion of partly occluded objects and illusory objects involve the same or similar mechanisms at critical stages of contour interpolation. B. L. Anderson, M. Singh, and R. W. Fleming and B. L. Anderson (2007) presented a number of…

The influence of attention on perceptual awareness was examined using metacontrast masking. Attention was manipulated with endogenous cues to assess the effects on the temporal and spatial parameters of target visibility. Experiment 1 examined the time course of effective masking when the target and mask set were presented at an attended vs. an…

Our body-shadows are special stimuli in the visual world. They often have anatomical resemblance with our own body-parts and move as our body moves, with spatio-temporal correlation. Here, we show that self-attributed body-shadows cue attention to the body-part they refer to, rather than the location they occupy. Using speeded spatial…

Two experiments investigated how 16-20-week-old infants visually tracked an object that oscillated on a horizontal trajectory with a centrally placed occluder. To determine the principles underlying infants' tendency to shift gaze to the exiting side before the object arrives, occluder width, oscillation frequency, and motion amplitude were…

Asperger Syndrome (AS), a condition on the autistic spectrum, is characterized by deficits in the ability to use social cues to infer mental state information. Few studies have examined whether these deficits might be understood in terms of differences in visual information processing. The present study employed functional magnetic resonance…

A holographic process is presented where the object is made of the real image produced by a two-mirror system. Single-step reflection hologram recording is achieved. Details of the process are given, optics concepts are outlined and demonstrative results are presented. (Contains 6 figures and 2 footnotes.)

Upside-down inversion disrupts the processing of spatial relations between the features of a face, while largely preserving local feature analysis. However, recent studies on face inversion failed to observe a clear dissociation between relational and featural processing. To resolve these discrepancies and clarify how inversion affects face…

Four experiments examined young children's knowledge about the visual characteristics of writing, specifically personal names. Children younger than 4 years of age, even those who could read no simple words, showed some knowledge about the horizontal orientation of English names, the Latin letters that make them up, and their left-to-right…

We combine the Dimension-Action (DA) model with translational models to account for both the Stroop and the flanker effects. The basic assumption of the model is that there are distinct visual modules, each of which is endowed with both perception and response selection processes. We contrast this model with an alternative widespread view, the…

Kindergarten children were exposed to a behavior modification training activity involving perceptual scanning, which was designed to increase the field-independent mode of perception. The training was evaluated, based upon a group of 18 experimental subjects and a control group of 17 children. Subjects in the training group were individually…

This study examined differences in the number of perceptual judgment modifications made by 36 subjects showing different levels of dogmatism when the source of information was manipulated among superior, subordinate, and peer sources. An experimental and a control group were used, and a 2x3 factorial analysis design was developed. Dogmatism was…

In teaching students how to write, the utilitarian aspect does not need to be ignored, but--more important--the imaginative, expressive aspect should be emphasized. Since all writing depends on the full resources of the imagination, students need to be taught how to recreate or vivify people, objects, scenes, and feelings. A process which helps…

Based on the premise that perception is a continual series of simple hypotheses about the external world which are built up and selected by sensory experiences, this book explores in detail some of the major findings in perception and speculates about interconnections between sensory experiences, brain function, perception, and language and…

Techniques have been developed for research and teaching purposes on the sensory losses that accompany the aging process. By experiencing the sensory loss, those working with the aged understand how the environment and professional interaction can assist, support, and enhance coping and functioning by the older person.

Points out that oral reading involves visual, auditory, and kinesthetic perception and that it is impossible to divide reading methods into auditory and visual categories. Discusses the need to discover whether a child's perceptual abilities are directly related to his learning propensities and lists several other areas of needed research.…
