Visual Task Demands and the Auditory Mismatch Negativity: An Empirical Study and a Meta-Analysis
Fig 5
Meta-analysis of how visual task demands changed the MMN (forest plot on left and funnel plot on right).
The analysis focused on the mean amplitudes at Fz (between about 100 and 250 ms after stimulus onset) and was expressed in μV (with 95% CI). The overall negative effect shows that the MMN (i.e., deviant minus standard) was more negative during low than high visual demands (i.e., MMN during low demands minus MMN during high demands). See main text for references to the individual studies. In the forest plot (left), the size of each square corresponds to the weight in the meta-analysis.
