The development of infant sensitivity to biomechanical motions.

Findings from 3 experiments are interpreted as suggesting that infants, by 36 weeks of age, are extracting fundamental properties necessary for interpreting a point-light display as a person.

Perception of biomechanical motions by infants: implementation of various processing constraints.

It is suggested that infants are sensitive to local rigidity in biomechanical displays but that this sensitivity is orientation specific, and possible mechanisms for this specificity are discussed in the context of additional constraints on the processing of biomechanicals displays.

Perception of the symmetrical patterning of human gait by infants.

Findings suggest that 3-month-old infants respond to the absolute and relative motions within a single limb, whereas 5-month old infants respond primarily to the relations between limbs and, in particular, to the bilateral symmetry between the limbs.

Infant use of relative motion as information for form: Evidence for spatiotemporal integration of complex motion displays

It is concluded that infants demonstrate the capacity to integrate the information contained within nonuniform trajectories into a coherent structure by 7 months of age.

Young Infants Detect the Direction of Biological Motion in Point-Light Displays.

It is reported that 6-month-old infants can differentiate leftward and rightward motions from a movie depicting the sagittal view of an upright human point-light walker, walking as if on a treadmill.

Three Months-Old’ Preferences for Biological Motion Configuration and Its Subsequent Decline

It is found that three-month-old infants prefer a coherent point-light walker in relation to a scrambled display, but both five- and seven-month old infants do not show any preference, and the different perceptual, attentional, motor, and brain processes available at each age group are discussed.

Infants perceive human point-light displays as solid forms.

Six- and nine-month-old infants showed significantly greater recovery of attention to the final phase of testing whether infants would selectively apply the principle of solidity to upright human displays, suggesting that infants are able to bind a solid vertical form to human motion.

Biological motion preference in humans at birth: role of dynamic and configural properties.

Results confirm and extend previous comparative and developmental data, supporting an inborn predisposition to attend to biological motion in humans.



The Perception of Relative Motion by Young Infants

By five months of age, infants seem to be sensitive to relative-motion cues, and presumably have the ability to group moving stimuli perceptually.

Spatio-temporal differentiation and integration in visual motion perception

A complex vector analysis of the proximal motion pattern is accomplished at the initial stage of physiological signal recording and that it is a consequence of receptive field organization is indicated in terms of vector calculus.

Development of visual organization: the perception of subjective contours.

Findings are interpreted as indicating that infants can perceive subjective contours, however, the age of this accomplishment probably varies with both the characteristics of the array and the abilities of the observer.

Coding Theory Adapted to Gait Perception

Restle's coding theory for movement perception is merged with certain aspects of Johansson's vector descriptions of movement to investigate the relative perceptual prominence of several kinds of

Gait Perception as an Example of How We May Perceive Events

In An Essay Concerning Human Understanding, John Locke (Locke, 1690/1959, 11:8:9) listed five primary qualities of objects in the world around us: solidity, extension, figure, number, and motion.

Visual perception of biological motion and a model for its analysis

The kinetic-geometric model for visual vector analysis originally developed in the study of perception of motion combinations of the mechanical type was applied to biological motion patterns and the results turned out to be highly positive.

Visual motion perception.

The author uses projective relations as the theoretical foundation of his investigations of visual space and motion and concludes that during locomotion the components of the human visual environment are interpreted as rigid structures in relative motion.

Infant responses of ocular fixation to moving visual stimuli.

A program to generate synthetic walkers as dynamic point-light displays

Using a technique that began with the work of Marey (1895/1972), Johansson (1973, 1975, 1976) has begun to explore the underlying stimulus structure of biological motion. One version of the technique
