Seven-year-olds compared successively presented oblique lines which varied as to their position within a square display and their relation to the diagonal axis of the display. Children apparently encoded lines in terms of position and axis features. They used a categorical spatial representational system to compare oblique lines. (Author/RD)

Finke and Kurtzman report that fields of resolution increase with increases in the diameter of both perceived and imagined circular patterns. In contrast, we find no such increase for imagined circular patterns when the experimenter is not aware of the experimental predictions, even though our subjects received imagery training.

Four experiments show that observers can selectively attend to one of two stationary superimposed pictures. Selective recognition occurred with large displays in which observers were free to make eye movements during a 3-sec exposure and with small displays in which observers were instructed to fixate steadily on a point. (Author/RD)

The time needed to process visual feedback information for the control of aimed movements was investigated in two experiments. Examination of movement patterns indicated that the average time between presentation of visual error information and initiation of a movement correction was 135 msec, which is shorter than previous estimates.

How strategies affect learning of categories that lack necessary and sufficient attributes is explored. The authors propose that strategy variations induced by instructions affect only the amount of information represented about attributes, not processes operating on representations. An experiment required subjects to classify schematic faces into…

Discusses how an individual's visual system processes cues to motion in depth. A theoretical model of the operations of the visual system that underlie the perception of motion in depth is included. (HM)

The effects of stimulus duration and contrast on duration of visible persistence as a function of spatial frequency were investigated in normal and specific-reading-disabled children. Results suggest that disabled readers have different contrast processing at low and high spatial frequencies and indicate differences between readers in basic visual…

Three groups of eight Ss (Down's syndrome, CA control, and MA control) received a battery of tests to assess recall and recognition memory using either auditory or visual input with verbal and nonverbal responses. Results indicated that the Down's syndrome group possessed deficits in both storage and retrieval abilities, with storage of visually…

Shows how photographs of teenagers were used to trigger high school students' creative writing. Provides samples of student poetry. (RL)

One hundred thirty-six 5-to-10-year-old Israeli children were given three black and white photographs of a highway, a column of identical tanks, and a row of elephants, and were asked some questions on each one of the photographs in order to elicit responses of three-dimensional perception. (CM)

A comparative assessment of eight normal and eight psychotic children in a stimulus generalization paradigm using simple and complex figures. Six of the subjects fulfilled the criteria for infantile autism. (CM)

Establishes the validity of the Picture Potency Formula as a tool to predict the extent to which children will respond to pictures. (FL)

Forty elementary children (six and nine year olds) and 20 college students were required to discriminate identical pairs of visual stimuli from mirror images. It was hypothesized that a key factor in performance would be the extent to which orientation was a functionally significant attribute of the stimuli. (Author/MP)

In order to examine whether the visual picture of the mother would, by itself, encourage toddlers to play in an unfamiliar situation, the effects of films of mothers were compared to the actual presence of the mothers, and to films of unfamiliar women. (CM)

"32 English readers and 32 Hebrew readers were shown stimuli with directional characteristics (English and Hebrew letters) and stimuli with no directional characteristics (arrays of different circles, bars, colors, and geometric figures) for scanning. The results showed that, while directional stimulus characteristics affected the direction…
