While running up an incline at a speed chosen by themselves, subjects apparently will perceive the work effort to be the same as running on the level, when in fact it is costing them more energy. (MM)

Results indicate that infants are able to recognize a human face from a specific motion pattern even when the face lacks static facial features. (PCB)

Examines discrimination of geometric shapes by three-month-old infants who were presented with geometric stimuli moving laterally at two different velocities. Finds that subjects discriminate between geometric forms at velocities that, according to previous findings, might interfere with shape discrimination. Discusses the possible interactive…

Pulsed ultrasound was used to study tongue movements in the speech of children from 3 to 11 years of age. Speech data attained were characteristic of systems that can be described by second-order differential equations. Relationships observed in these systems may indicate that speech control involves tonic and phasic muscle inputs. (Author/RH)

Accuracy of horizontal arm-positioning toward the midline of the body was investigated, comparing two methods of presentation of the test position (verbal versus passive movement) and three extents of angular displacement. (RC)

The tracking behavior of Infants up to 5 months of age was studied using linear and circular trajectories, with partial occlusion of the trajectories. Results indicate that it is not until the age of about 16 weeks that infants can be said to be tracking a moving object as an object. (Author/WY)

"The results of the present study demonstrate that 10-month-old infants will move away from their mothers into a wider environment and that the properties of the wider environment control, in part, the infant's departure. (Author)

Holograms of faces were used to study two- and five-month-old infants' discriminations of changes in facial expression and pose when the stimulus was seen to move or to remain stationary. While no evidence was found suggesting that infants preferred the moving face, evidence indicated that motion contrasts facilitate face recognition. (Author/RH)

Six experiments assessed 4- to 8-month-old infants' reactions to probable and improbable orientation positions following invisible transformations from an original orientation. Availability of orientation cues, objects' path of motion, and amount of invisible spatial transformation were varied. Results indicated that infants as young as 4 months…

Assessed 14-week-olds' attention to green or red target objects moving in a field of distracting objects that varied in color. Found that infants' detection of green moving targets was masked in the presence of mixed red and green objects. Masking was not observed for red targets or for green targets in a field of green objects. (BC)

Being physically educated means one has the tools--the abilities, knowledge, experiences, and awareness--to find meaning in movement, thereby enlarging oneself and one's world. Teachers should not teach fitness, skills, rules, or strategies for their intrinsic value. Instead, teachers should teach movement in all its varied forms. (IAH)

Derives a general equation for the period of nonsimple harmonic motion where the magnitude of the restoring force is given by F=kxn. (JRH)
