Point-light walkers with and without local motion features for determining direction
نویسندگان
چکیده
In 1978, James Cutting published an algorithm to generate point-light displays that resemble the movements of the joints of a human walker. The method has since been used frequently to create stimuli for research on biological motion perception. More recently, Troje and Westhoff (2006) found that pattern of local movement of the feet was used to derive the direction in which a pointlight walker is facing, even when structural information is removed. The results of previous studies that direction could not be determined using a scrambled version of Cutting's walker, may be explained by the significantly different motion of the feet between Cutting's walker and motion-captured humans.

Effects of aging on biological motion discrimination
Previous studies have shown that older subjects have difficulties discriminating the walking direction of point-light walkers. In two experiments, we investigated the underlying cause in further detail. In Experiment 1, subjects had to discriminate the walking direction of upright and inverted point-light walkers in a cloud of randomly moving dots. In general, older subjects performed less accu...
متن کاملContribution of coherent motion to the perception of biological motion among persons with Schizophrenia
People with schizophrenia (SCZ) are impaired in several domains of visual processing, including the discrimination and detection of biological motion. However, the mechanisms underlying SCZ-related biological motion processing deficits are unknown. Moreover, whether these impairments are specific to biological motion or represent a more widespread visual motion processing deficit is unclear. In...
متن کاملLocal-to-global form interference in biological motion perception.
Point-light walkers have been useful to study the contribution of form and motion to biological motion perception by manipulating the lifetime, number, or spatial distribution of the light points. Recent studies have also manipulated the light points themselves, replacing them with small images of objects. This manipulation degraded the recognizability of biological motion, particularly for loc...
متن کاملLocal form interference in biological motion perception
Replacing the local dots of point-light walkers with complex images leads to significant detriments to performance in biological motion detection and discrimination tasks. This detriment has previously been shown to be larger when the local elements match the global shape in object category and facing direction. In contrast, studies using Navon stimuli have demonstrated that local interference ...
متن کاملContribution of configural information in a direction discrimination task: Evidence using a novel masking paradigm
Understanding how structure and motion information contribute to the perception of biological motion is often studied with masking techniques. Current techniques in masking point-light walkers typically rely on adding surrounding masking dots or altering phase relations between joints. Here, we demonstrate the use of novel stimuli that make it possible to determine the noise level at which the ...
