AB  - A recent series of studies of the auditory equiprobable Go/NoGo task, using fixed 
      interstimulus intervals (ISIs), proposed a processing schema relating observed 
      event-related potential (ERP) components to sequential processing stages. 
      However, it has been demonstrated that attention and ERP components can be 
      affected by the predictable rhythmic timing of fixed ISIs. Hence the aim of the 
      current study was to test the robustness of that processing schema with an 
      unpredictable arrhythmic variable ISI. EEG was recorded from 30 university 
      students at 30 scalp sites in an unwarned auditory equiprobable Go/NoGo task 
      using a variable ISI. Following our previous studies, Go and NoGo ERP components 
      were derived using temporal principal components analysis (PCA). Of the 
      unrestricted Varimax-rotated factors, seven were identifiable as components based 
      on their topography, polarity, and latency: two subcomponents of the N1 (N1-1, 
      and processing negativity, PN), P2/N2b, N2c/P3a, P3b, and two subcomponents of 
      the slow wave (SW-1 and SW-2). These components showed Go/NoGo effects comparable 
      to those previously noted with fixed ISI, supporting the proposed processing 
      schema. The Late Positivity (LP) component, previously speculated to mark 
      cortical deactivation after processing the NoGo stimulus, was not present in the 
      sequence of components. In its absence, activity underlying the observed 
      sustained P300/late positive complex may be involved in processing 
      temporally-uncertain stimuli.
