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)

Examines, with skepticism, the history and development of forensic phonetics in response to the publication of "Forensic Phonetics" by J. Baldwin and P. French (1990). Three issues are specifically explored: (1) whether voices are unique, (2) whether a purely auditory approach is adequate, and (3) whether legally sufficient conclusions…

Reports on three experiments showing the crucial importance of the "half boundary" in children's proportional judgments. Concludes that the concept of "half" plays a crucial role in children's early proportional reasoning and that the half boundary is similar to, though not as powerful as, the category boundaries discovered in…

Notes that people often see what they expect to see, have learned to see, or want to see. Presents theoretical discussion of perception and cognition. Identifies 10 skills for correcting perceptual and cognitive processes involved in dealing with incoming stimuli. Proposes that these skills will increase social workers' accuracy in making…

Discusses visual perception; the way technology can change the way people see; combining seeing and technology to create visual cultures; the influence of the World Wide Web on visual technologies; and changes in visual culture, including museums and their Web sites. (LRW)

Examines what 180 students think about electronic monitoring and compares their perceptions to those of 29 electronically-monitored offenders. Results show that students were less supportive of electronic monitoring but when asked about what offenders have to give up, they viewed the sanction more punitively than did offenders. Implications…
