Publisher Summary This chapter defines two common classes of perceptual anisotropy.
They are perceptual salience of the main orthogonals, meaning the orientation hierarchy of …

Symmetry has long been viewed as a feature of objects that facilitates ease of perception.
Three experiments investigated 4-to 5-month-old infants' detection and processing of vertical …

Symmetrical visual patterns, particularly vertically symmetrical ones, are preferred and
processed faster than asymmetrical patterns by adults. Results of 3 experiments with 61 4 …

Conducted 3 experiments to assess the development of symmetry perception in children
between the ages of 4 and 6 yrs. Exp I employed a learning task in which 72 Ss were asked …

The anisotropic properties of space have received intermittent study some time. Takala (ii) in
his summary of the pertinent literature and in his own experimental work pointed up the fact …

Visual perception in human adults varies throughout the visual field, both across eccentricity—
decreasing with distance from the center of gaze—and around isoeccentric locations—that …

Four experiments were conducted to assess converging aspects of 4-month-old infants'
perception of symmetry in visual patterns. Experiments 1 and 2 manipulated the structure …

Two psychophysical studies show that 5–11-yr-old children are increasingly likely to have
greater visual sensitivity for horizontal and vertical sinusoidal gratings than for diagonal …

The normal human adult can see the difference between a" Z" and an" N". A lateral rotation
of just 90 degrees produces a stimulus change in this graphic form, which is easily …

One of the most obvious characteristics of the visual world is its stability. The world does not
rotate as you turn around (you would become badly disoriented if it did) nor does it shoot …
