Contingent Negative Variation
Research News and Information
Definition of 'Contingent Negative Variation'A negative shift of the cortical electrical potentials that increases over time. It is associated with an anticipated response to an expected stimulus and is an electrical event indicative of a state of readiness or expectancy. Common names: Contingent Negative Variation; Contingent Negative Variations; Negative Variation, Contingent; Negative Variations, Contingent; Variation, Contingent Negative; Variations, Contingent Negative; Bereitschaftspotential; Readiness Potential |

Mental training enhances attentional stability: neural and behavioral evidence.
19 Oct 2009
The capacity to stabilize the content of attention over time varies among individuals, and its impairment is a hallmark of several mental illnesses. Impairments in sustained attention in patients with attention disorders have been associated with ... Read more...
Processing of auditory location changes after horizontal head rotation.
12 Oct 2009
Under natural conditions, our sound localization capabilities enable us to move constantly while keeping a stable representation of our auditory environment. However, since most auditory studies focus on head-restrained conditions, it is still ... Read more...
ERP evidence for flexible adjustment of retrieval orientation and its influence on familiarity.
29 Sep 2009
The assumption was tested that familiarity memory as indexed by a mid-frontal ERP old-new effect is modulated by retrieval orientation. A randomly cued category-based versus exemplar-specific recognition memory test, requiring flexible adjustment of ... Read more...
