In order to examine the degree to which form perception affects the formation of apparent-motion experience, subjects were presented with nine ambiguous apparent-motion situations, where the elements of each single flash were various figures. (Editor)

It was hypothesized that a moving or stationary observer who samples an ambient optic array specific to egomotion over a flat plain obtains a phenomenal experience of egomotion over that environment and further that the focus of expansion need not be present in the optic array sample for an observer to perceive his heading and egomotion.…

The purpose of the present work was to investigate the relation between pattern goodness and accuracy of reproduction in backward masking. It may be hypothesized that good patterns, being easier to encode as wholes, will be reproduced more easily than poorer patterns. Four experiments were performed. (Author)

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)

The purpose of the present experiment was to compare auditory with visual perception of rhythmic temporal patterns. (Author)

The main objective of the present investigations was to determine whether or not young human infants see the physical spectrum in a categorical fashion as human adults and animals who possess color vision regularly do. (Author)

Attempts to replicate Gogel's (1972) observations with points of light and examines in addition whether the same results would be obtained if the binocularly nearer object was made visually more massive than the farther object and if the residual oculomotor cues were varied to produce different values of the reference distance. (Author/RK)

Four studies showed that a substantial proportion of their subjects, aged four to seven years, responded as if elements "out of sight" in pictures were either nonexistent or imcomplete. Termed "literalism," this mode of responding was related to age but little influenced by training or another form of structured experience.…

In a replication and extension of an experiment by Eagle, Wolitzky & Klein (1966), subjects wrote brief stories describing an Object Relations Test card following exposure to a 7 x 7 letter matrix in which were embedded either neutral words or emotive words. (Editor)

Article investigated the pattern of results for three series of tests in which monkeys were deprived of sight of their limbs from birth. (Author/RK)

The relationship between perceptual sensitivity and stimulus emotionality was investigated employing a methodology aimed to preclude the intervention of response variables. (Editor)

The primary concern in this study has been to interpret the ways in which perception of a letter depends on properties of other letters present in the same display. (Author)

A tachistoscopic recognition task was administered to 36 retarded readers and 36 normal readers aged 6.5 to 7.5 yr. The purpose was to determine whether the retarded readers' visual-perceptual deficit was a function of speed of exposure and/or difficulty of discriminating alternatives on response cards. (Editor)

The influence of stimulus number and familiarity on judged duration were investigated. Results showed that the number of stimulus elements presented within a given interval affected its perceived duration, although the familiarity of those elements (as defined herein) did not. (Editor/RK)

Explores the possibility that measurable individual differences in hypnotic susceptibility or the ability to attend selectively to informational cues may account for a portion of the variability found in several types of geometrical visual illusions. (Author/RK)
