Figure 3: Topographic maps of the primary study-phase and test-phase effects.

Statistical comparisons of mean ERP amplitudes at each electrode site were used to generate t-maps with spherical spline interpolation on a schematic view of the head from above. (a) Study-phase topography showing t-values from the comparison of later false memories to later correct rejections from 600–900 ms. Positive t-values > 2.23 (uncorrected) indicate regions where ERPs in response to later false memories were significantly more positive than ERPs in response to later correct rejections. (b) Test-phase topography showing t-values from the comparison of accurate picture memories to false memories from 900–1200 ms, RT - matched. Positive t-values > 2.20 (uncorrected) indicate regions where ERPs to accurate picture memories were significantly more positive than ERPs to false memories.
