Developmental prosopagnosia (DP) is a severe impairment in identifying faces that is present from early in life and that occurs despite no apparent brain damage and intact visual and intellectual function. Here, we investigated what aspects of face processing are impaired/spared in developmental prosopagnosia by examining a relatively large group…

Representational momentum refers to the phenomenon that observers tend to incorrectly remember an event undergoing real or implied motion as shifted beyond its actual final position. This has been demonstrated in both visual and auditory domains. In 5 pitch discrimination experiments, listeners heard tone sequences that implied either linear,…

The purposes of this study were to: (a) examine differences within specific kinematic variables and ball velocity associated with developmental component levels of step and trunk action (Roberton & Halverson, 1984), and (b) if the differences in kinematic variables were significantly associated with the differences in component levels, determine…

The authors describe 3 human spatial navigation experiments that investigate how limitations of perception, memory, uncertainty, and decision strategy affect human spatial navigation performance. To better understand the effect of these variables on human navigation performance, the authors developed an ideal-navigator model for indoor navigation…

The authors proposed a model of the control of interceptive action over a ground plane (Chardenon, Montagne, Laurent, & Bootsma, 2004). This model is based on the cancellation of the rate of change of the angle between the current position of the target and the direction of displacement (i.e., the bearing angle). While several sources of visual…

A multiple-baseline design was used to evaluate the effects of a pre-shot putting routine on the putting performance of four NCAA Division I golfers. The routine involved a combination of multisensory imagery and simulated putting movements. Results suggested that the intervention was effective for some participants. Discussion focuses on…

Presents one approach to solving problems concerned with minimum stopping distances. In this approach differing negative accelerations are considered in addition to the speed and reaction time. (GS)

Article described a course taught at a university department of theater that was designed to deepen our cognizance of the potential of the human body as a dance instrument as it widened our knowledge of dance in the context of human history. (Author/RK)

Diagrams and photographs are incorporated in an explanation of the physics involved in the skills of diving and swimming. (CP)

Examines the relationship between the ease with which a picture is interpreted and the structural similarity between the picture and the subject it represents. Preschoolers, first graders, sixth graders, and college students participated in the study. (CW)

Presents instructions for constructing an electronic device that provides the release of two spheres from the same point, one vertically and the other with a horizontal motion. (GS)

Describes an experiment developed to study the velocity components of thermionic electrons, temperature-limited emission, cathode and anode work functions, and the contact difference in potential between cathode and anode. (Author/GS)

Emphasizing the importance of economy and efficiency in the production of computer animation, this master's thesis outlines methodologies that can be used to develop animated sequences with the highest quality images for the least expenditure. It is assumed that if computer animators are to be able to fully exploit the available resources, they…
