Allocation of attention to biological motion: local motion dominates global shape.
Directional information can be retrieved from a point-light walker (PLW) in two different ways: either from recovering the global shape of the articulated body or from signals in the local motion of individual dots. Here, we introduce a voluntary eye movement task to assess how the direction of a centrally presented, task-irrelevant PLW affects the onset latency and accuracy of saccades to peri...
متن کاملLocal and global information in biological motion
Animate motion patterns are a rich source of biologically significant information. They quickly and reliably signal the presence of an animate agent and convey its identity, actions and intentions. Observing other people in motion, our visual system is able to retrieve information about sex, age and weight of a person and can even detect signatures that identify a familiar individual. The relev...
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 کاملAdaptation to spiral motion: global but not local motion detectors are modulated by attention
In this study, we investigated the effect of attention on local motion detectors. For this purpose we used logarithmic spirals previously used by Cavanagh and Favreau [Perception, 1980, 9(2), 175-182]. While the adapting stimulus was a rotating logarithmic spiral, the test stimulus was either the same spiral or its mirror image. When superimposed, all contours of the spiral stimulus and its mir...
متن کاملCharacterizing global and local mechanisms in biological motion perception.
The perception of biological motion is subserved by both a global process that retrieves structural information and a local process that is sensitive to individual limb motions. Here, we present an experiment aimed to characterize these two mechanisms psychophysically. Naive observers were tested on one of two tasks. In a walker detection task designed to address global processing, observers we...
