Local form-motion interactions influence global form perception.
Object motion perception depends on the integration of form and motion information into a unified neural representation. Historically, form and motion perception are thought to be independent processes; however, research has demonstrated that these processes interact in numerous and complex ways. For example, an object's orientation relative to its direction of motion will influence its perceiv...
متن کاملHemispheric processing of global form, local form, and texture.
Hemispheric processing of global form, local form, and texture of hierarchical patterns composed of many, relatively small elements and patterns composed of few, relatively large elements was examined in two experiments, employing a Stroop-type paradigm. In experiment 1 subjects were instructed to attend either to the global or the local level of the pattern and to identify the form at the desi...
متن کاملGlobal and Local Attention Processing in Depressed Mood
Background: Attention impairments are the hallmark feature of subclinical depression. The present study used Navon task to compare the allocation of attention to the local and global stimuli in depressed and nondepressed participants. Method: The primary sample included 186 female high school students from Shiraz city who were selected using cluster sampl...
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 versus global perception of ambiguous motion displays.
Four pairs of spots rotating around their common centers, each pair a "doublet", were arranged in a square formation. The doublets initially appear to rotate "locally", but then coalesce into two large squares that slide over each other along circular paths ("global" motion). This perceptual transition from local to global motion occurred within and across a series of repeat trials (Experiment ...
