One- and two-month-old infants were shown schematic drawings of a human face with features arranged (1) naturally, (2) symmetrically but scrambled, and (3) asymmetrically and scrambled. Two-month-olds discriminated among all arangements and preferred the natural arrangement; one-month-olds showed no discrimination or preference. (Author/DB)

Using 60 subjects, aged five to eight, this study assessed the magnitude of relation between deaf children's perceptual motor development, measured by the Developmental Test of Visual Perception, and their language development. The relationship was positive and significant, but the value too small to indicate reliable association for individuals.…

Shows how to use Rudolf Arnheim's theory of visual thinking in technical writing classes. (RL)

Investigates the magnitude of the over- and under-estimated portions of the Ebbinghaus (Titchner's circles) illusion in 688 subjects ranging in age from 5 to 70 years. (Author/SS)

Explores sensory experiences, both real and imagined, that occur while reading. (MKM)

Three experiments investigated four-month-old infants' capacity to perceive bimodally specified events by detecting the temporal synchrony of sound bursts with the visable impacts of surfaces. (Author/SS)

The effectiveness of motion parallax for relative and absolute distance judgments was studied using second-, fourth-, and sixth-grade children and college students. (JMB)

Schoolboys from the Ivory Coast and from Kenya were tested on a simple task intended to detect the effect of implicit-shape constancy. (Editor)

In answer to R. Allington's criticism of the Jordan Left-Right Reversal Test (JLRRT), the author contends that Allington's research used an outdated version of the JLRRT, that Allington's research into the relationship of visual reversals to reading skills does not reflect on the validity of the test to measure reversals.

Separation thresholds for groups of 26 dyslexic and normal children attending the first year of secondary school were obtained with pairs of identically-oriented and spatially-overlapping straight lines presented at orientations varying from zero to 90 degrees. (Editor)

It is much easier to look for an unfamiliar character (such as an upside down A) embedded among familiar ones than to look for a familiar character (A) among unfamiliar ones. Furthermore, the nature of the background seems more important toperformance than the nature of the target. (Editor)

Five experiments investigated children's understanding that expectations based on prior experience may influence a person's interpretation of ambiguous visual information. Results suggest that understanding of interpretation begins at approximately six years of age. (HTH)

Examined effects on duration of gaze of infant- and adult-directed (ID and AD) speech signalling presentation of adult faces. Found that, when ID speech segments signaled presentation of a smiling, sad, fearful, or angry face, significant and comparable conditioning occurred with the smiling and sad faces, whereas nonsignificant and more variable…

Three studies investigated whether eye gaze cueing in 4-month-old infants is the result of a domain-specific module or reflects the activity of domain-general processes. In two of three experiments, infants perceived apparent motion of the pupils, and this directly elicited saccades, but only when this motion was preceded by a period of direct…

Discusses why public perceptions of the importance of Kettlewell's investigations on the phenomenon of industrial melanism diverge from those of researchers who actually work on the phenomenon. Explains the important role photographic and film depictions of differential bird predation play in Kettlewell's popularizations. (Author/SOE)
