contingent negative variations การใช้

• It is the contingent negative variation ( CNV ).
• These potentials include the contingent negative variation ( CNV ), readiness potential, movement-related potentials ( MRPs ), and N400 potentials.
• These components are the Bereitschaftspotential ( abbreviated BP, and also known as readiness potential, abbreviated RP ) and the Contingent Negative Variation ( CNV ).
• Walter ( 1937, 1953 ) named the delta waves and theta waves, and the contingent negative variation ( CNV ), a slow cortical potential that may reflect expectancy, motivation, intention to act, or attention.
• Later studies on event preparation examining the foreperiod of the contingent negative variation ( CNV ), which orients the subject to respond to warned stimuli, and the foreperiod of the LRP were used to study the exact mechanism of event preparation.
• In the 1960s Walter also went on to discover the " contingent negative variation " ( CNV ) effect ( or " readiness potential " ) whereby a negative spike of electrical activity appears in the brain half a second prior to a person being consciously aware of movements that he is about to make.

• Though some ERP components are referred to with acronyms ( e . g ., contingent negative variation  CNV, error-related negativity  ERN, early left anterior negativity  ELAN, closure positive shift  CPS ), most components are referred to by a letter ( N / P ) indicating polarity ( negative / positive ), followed by a number indicating either the latency in milliseconds or the component's P300 component may exhibit a peak anywhere between 250ms  700ms.
