We tested the ability of children 3–5 years of age to recognise biological motion displays. Children and adults were presented with moving point-light configurations depicting a walking person, four-legged animals (dogs), and a bird. Participants were able to reliably recognise displays with biological motion, but failed in the identification of a static (four consecutive frames taken from each sequence) version. The results indicate that, irrespective of the highly reduced and unusual…

Biological Motion Shown Backwards: The Apparent-Facing Effect
The findings suggest that in interpreting impoverished point-light biological-motion stimuli the visual system may neglect distortions caused by showing a film backwards, and this property appears to be robust across perceptual development.
Perception of Elliptic Biological Motion
The findings indicate that adults are highly sensitive to violation of the two-thirds power kinematic law, and possible ways for a cross-talk between perception and production of biological movement, and the brain mechanisms involved in biological motion processing are discussed.
The Development of Sensitivity to Biological Motion in Noise
Development of sensitivity to biological motion implies an immaturity at 6 years of age in the neural networks involved specifically in the processing of biological motion, networks that may include the superior temporal sulcus (STS).
Development of motion processing in children with autism.
Children with autism were particularly impaired in processing biological motion in relation to any developmental measure (chronological or mental age), and there was some developmental overlap in ability to process other types of visual motion between typically developing children and the children with autism, and evidence of developmental change in both groups.
Perception of Pointing from Biological Motion Point-Light Displays in Typically Developing Children and Children with Autism Spectrum Disorder
TD children, but not children with ASD, were faster to identify a validly cued target than an invalidlyCued target and a scrambled version of the point-light pointing gesture produced no validity effect in either group.
Infant Behavior and Development he development of gaze behaviors in response to biological otion displays
The results suggest that the ability to process the higher-level information provided by biological motion patterns, such as the attentional direction of others, develops by 12 months, but not by 9 months, of age.
Sensitive perception of a person's direction of walking by 4-year-old children.
Evidence is presented that 4-year-old children are sensitive to small differences in a person's direction of walking (∼7°) far beyond what has been previously shown, and this sensitivity only occurred for perception of an upright walker, consistent with the recruitment of high-level visual areas.
Dissociable cortical processing of recognizable and non-recognizable biological movement: analysing gamma MEG activity.
The stimulus-specific time course and topographic dynamics of cortical oscillatory activity indicate that the brain rapidly dissociates spatial coherence and meaning revealed through biological movement.
Perception and production of biological movement in patients with early periventricular brain lesions.
Visual sensitivity to biological motion in adolescents who were born very preterm is examined using the simultaneous masking paradigm, favouring the assumption that the common network for perception and production of biological motion might be inherent for the brain.


Recognition of Animal Locomotion from Dynamic Point-Light Displays
The ability to interpret biological motion is general and is not restricted to human movements.
Low-level visual processing of biological motion
Results suggest that the effect relies upon responses in low-level motion-detecting processes, which operate over short temporal and spatial intervals and respond to local modulations in image intensity, and does not involve hierarchical visual analysis of motion components.
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.
Subconfigurations of the human form in the perception of biological motion displays.
The perception of biological motion by human infants.
The results of this experiment demonstrate that infants 4 to 6 months of age exhibit a preference for biological motion patterns, and support the hypothesis that this perception of biological motion is an intrinsic capacity of the visual system.
Infant sensitivity to figural coherence in biomechanical motions.
Seeing biological motion
The steepness of the summation curves indicates that the mechanisms that analyse biological motion do not integrate linearly over space and time with constant efficiency, as may occur for other forms of complex motion, but instead adapt to the nature of the stimulus.

Performance in a direction discrimination task remained fairly constant across inter-stimulus interval (ISI) when the walker was presented within a random motion mask but increased with ISI when the mask motion duplicated the motion of thewalker.
Global Processing of Biological Motions
