Experiments investigated whether more elements in the upper part of a visual configuration influenced newborns' preference for face-like patterns. Findings indicated that newborns preferred nonface-like stimuli with more upper part elements over nonface-like stimuli with more lower elements, but did not prefer face-like over nonface-like stimuli…

Investigated 5-month-olds' perception of an object whose center was occluded and whose ends were visible only in succession. Found that infants perceived the object as one connected whole when the ends underwent common motion but not when the ends were stationary. Results suggest that infants perceive object unity but not object form. (Author/BC)

Investigated whether normal children could self-regulate intermittent cycle ergometer exercise using a prescribed target rating of perceived exertion (RPE), discriminate between target RPEs, and produce intermittent target RPEs in ascending and descending sequences. RPE was estimated using the Children's OMNI Scale of Perceived Exertion. Overall,…

Results provided evidence that 6- and 12-week-old infants' preferences for a moving set of stripes over a stationary set were based on the velocity rather than on the temporal frequency of stripe movement. Estimated velocity thresholds of 9 degrees per second for 6 week olds and 4 degrees per second for 12 week olds extended results of previous…

A comparison of parent and adolescent subjects' ratings of the adolescent subjects' pubertal stage with a nurse practitioner's ratings indicated that adolescent and parent ratings of pubertal development can be used when precise assessment is not required. For questions requiring absolute accuracy, ratings by trained health care personnel are…

Infants 7 to 8.5 months of age successfully differentiated 2 spectral structures in the context of variations in fundamental frequency, intensity, and duration. Subjects' performance with nonarbitrary categories could not be attributed to memorization of the familiarized set. (RH)

Research is reviewed for evidence that female responses to objects, images, and themselves constitute a different perspective or reality from those of males, and whether a different set of constraints exists in the relations between the male artist and his creation and between the female artist and hers. (MSE)

In three studies, infants reached for objects as distinct units when the objects moved separately or were separated in space. Otherwise, infants reached for objects as one unit. In one study, patterns of dishabituation provided further evidence that separated or separately moving objects were perceived as distinct units. (RH)

High functioning autistic individuals (N=16) were compared with age-matched normal control subjects on a visual recognition matching task. Autistic subjects performed particularly poorly on meaningless material, but were able to utilize meaning to aid their visual memory. Results did not support a simple parallel between autism and mediotemporal…

Fundamental concepts of Gaussian Recognition Theory are reviewed, and one of the major theorems used to test for perceptual independence among stimulus dimensions is disputed through a relatively simple counterexample. An amended version of the theorem, Theorem 4, is offered, and a simulation demonstrates its utility. (SLD)

A study investigated the effect of reduced relative frequency of feedback on the ability to calibrate kinesthetic awareness of 90 healthy young and older subjects. Results show that reduced relative knowledge of results frequency depressed the performance of the older subjects but raised performance of younger subjects in the acquisition phase.…

Suggests that within bureaucratic systems norms of behavior develop that can be classified as system-beating. Examines elements necessary for such behavior to occur: individual with role within system; system comprised of many specific roles; observation of practical actions and practical circumstances; interpretation of these circumstances;…

Argues that reality is different and unique for every species and every individual within a species. Language plays an integral part in the construct of human reality and brings intellectual order to the world of the senses. (MDM)

A model for solution of the motion correspondence problem is presented that is capable of maintaining the identities of individuated elements as they move. Many properties of the model are consistent with what is known about physiological mechanisms underlying human motion perception. (SLD)

The 1954 review of visual motion perception by James J. GIbson anticipated future developments in the field, but these developments were achieved without closely following Gibson's ideas. Reasons for the dormancy of his ideas are explored, and contemporary work on motion perception is evaluated from Gibson's perspective. (SLD)
