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criticism of the Jordan Left-Right Reversal Test (JLRRT), the author contends that Allington's research used an outdated version of the JLRRT, that Allington's research into the relationship of visual reversals to reading skills does not reflect on the validity of the test to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

Discussion of multimedia libraries and the need for storage, indexing, and retrieval techniques focuses on the combination of computer vision and data mining techniques to model high-level concepts for image retrieval based on perceptual features of the human visual system. Uses fuzzy set theory to measure users' assessments and to capture users'…

A new qualitative scoring system for the Rey Visual Memory Test was tested for its ability to distinguish between malingerers and nonmalingerers. The new system, based on the types of errors made, was able to distinguish between 53 psychiatrically disabled and 64 normal nonmalingerers, and between nonmalingerers and 91 possible malingerers.

Experiments involving a total of 114 college students from Indiana and Israel demonstrate that the initial analysis of visual objects into features from different dimensions strongly constrains postperceptual processes of response selection. A model of response selection is proposed to account for the findings. (SLD)

Used a habituation-dishabituation procedure to test ability of 4-, 5-, and 7-month-olds to differentiate between a subjective ellipse and a nonsubjective pattern that were constructed by displacing the inducing elements of the illusory figure. Found that even 4-month-olds discriminated between the subjective ellipse and nonillusory display. This…

Neuropsychological findings relevant to the question of whether visual imagery is visual or perceptual are reviewed and compared to cognitive psychology theories. Imagery does not appear to represent information acquired through visual sensory channels; rather, it seems to use some of the same neural representational machinery as does vision. (SLD)
