Figure 2.

A visual representation of the local–global oddball paradigm adapted to the auditory and visual domain. The top section represents the auditory paradigm where each tone represents a 500 Hz pure tone and the signal represents a white noise burst. The bottom section represents the visual paradigm where each sinusoidal grating is designed at 3 cpd and the noise stimulus is a white noise. In both paradigms the standard is played 25 times to establish the global rule and standard-deviant-omission sequences are played at 75%–15%–10% probability. The omission sequence is also played separately at 100%.
