The Default Mode Network Differentiates Biological From Non-Biological Motion.
The default mode network (DMN) has been implicated in an array of social-cognitive functions, including self-referential processing, theory of mind, and mentalizing. Yet, the properties of the external stimuli that elicit DMN activity in relation to these domains remain unknown. Previous studies suggested that motion kinematics is utilized by the brain for social-cognitive processing. Here, we ...
متن کاملContributions of form, motion and task to biological motion perception.
The ability of human observers to detect 'biological motion' of humans and animals has been taken as evidence of specialized perceptual mechanisms. This ability remains unimpaired when the stimulus is reduced to a moving array of dots representing only the joints of the agent: the point light walker (PLW) (G. Johansson, 1973). Such stimuli arguably contain underlying form, and recent debate has...
متن کاملMasking of motion by broadband and filtered directional noise
Observers deteeted unidireetional motion of isotropie dot patterns following exposure to (1) broadband noise eontaining all direetions of motion, or (2)noise from whieh eertain sets of direetion had been filtered. The amount of masking varied with the set of directions filtered from the noise, yielding broad directional tuning functions. The breadth of an observers's tuning funetion corresponde...
متن کاملAuditory motion affects visual biological motion processing.
The processing of biological motion is a critical, everyday task performed with remarkable efficiency by human sensory systems. Interest in this ability has focused to a large extent on biological motion processing in the visual modality (see, for example, Cutting, J. E., Moore, C., & Morrison, R. (1988). Masking the motions of human gait. Perception and Psychophysics, 44(4), 339-347). In natur...
متن کاملCortical and subcortical responses to biological motion.
Using fMRI and multivariate analyses we sought to understand the neural representations of articulated body shape and local kinematics in biological motion. We show that in addition to a cortical network that includes areas identified previously for biological motion perception, including the posterior superior temporal sulcus, inferior frontal gyrus, and ventral body areas, the ventral lateral...
