Neural mechanisms of social attention.
Social attention is conveyed primarily by gaze, but also by head and body orientation. These cues not only signal a seen agent's direction of attention but are also used to infer their current goals and intentions. Here, we review recent research showing that different gaze, head and body orientations are represented by distinct neural mechanisms, and show that a statistical summary of recent n...
متن کاملNeural Mechanisms of Intermodal Sustained Selective Attention with Concurrently Presented Auditory and Visual Stimuli
We investigated intermodal attention effects on the auditory steady-state response (ASSR) and the steady-state visual evoked potential (SSVEP). For this purpose, 40-Hz amplitude-modulated tones and a stream of flickering (7.5 Hz) random letters were presented concurrently. By means of an auditory or visual target detection task, participants' attention was directed to the respective modality fo...
متن کاملViewing the body modulates neural mechanisms underlying sustained spatial attention in touch.
Cross-modal links between vision and touch have been extensively shown with a variety of paradigms. The present event-related potential (ERP) study aimed to clarify whether neural mechanisms underlying sustained tactile-spatial attention may be modulated by visual input, and the sight of the stimulated body part (i.e. hands) in particular. Participants covertly attended to one of their hands th...
متن کاملNeural mechanisms of visual selective attention.
Visual selective attention improves our perception and performance by modifying sensory inputs at an early stage of processing. Spatial attention produces the most consistent early modulations of visual processing, which can be observed when attention is voluntarily allocated to locations. These effects of spatial attention are similar when attention is cued in a trial-by-trial, or sustained, f...
متن کاملNeural mechanisms of object-based attention.
What neural mechanisms underlie the ability to attend to a complex object in the presence of competing overlapping stimuli? We evaluated whether object-based attention might involve pattern-specific feedback to early visual areas to selectively enhance the set of low-level features corresponding to the attended object. Using fMRI and multivariate pattern analysis, we found that activity pattern...
