"Biological motion" Article Ideas:
Part of what I would hope to add to this article is a greater explanation of relevant experiments and studies that deal with uncovering more about the nature of biological motion processing. Particularly, I want to look at some studies that illustrate the difference between the recognition of "local elements" and the perception of "global form", as I think that this is necessary to understanding the process of biological motion.[1] Another experiment I hope to look into was done by Mather et al. (2016) which looks more into the brain structures which are necessary in biological motion processing.[2]
DRAFT:[edit]
Biological motion is the visual system's ability to perceive object movement by connecting a few small, individual stimuli. Humans use biological motion to identify familiar activities and gestures, useful for successful social behavior. Biological motion processing is a highly routine instance of more general perceptual and attentional processes that construct global form information from constituent parts.[3] Currently, research is being done to uncover the brain structures which allow for biological motion processing.
Experiments[edit]
Recent research has begun to focus on the brain structures that are necessary for this processing. Use of Transcranial Magnetic Stimulation gave evidence to suggest that biological motion processing is a dual process that looks at both form and motion, located outside of the MT+/V5 area.[2] Further evidence from another study show that the Default Mode Network is essential in distinguishing between biological and non-biological motion.[4] The results of such experiments indicate that biological motion perception is a process that pulls on several different brain systems even outside of the usual visual processing structures.
Other research looks into the differences between global and local processing of biological motion. One study investigated the contradiction by replacing the local dots of point-light displays with human images or stick figures; the results showed that the brain allocates fewer resources to the global form processing when the local elements are complex, indicating that the brain uses a similar form-based mechanism for the recognition of both global and local stimuli during processing.[1] The results also show that processing local images is an automatic process that interferes with the subsequent processing of the global form of the stimulus.
