Figure 1.
Face conflict paradigm example.
Example of congruent and incongruent trials as well as trial combinations for conflict adaptation effects. The individual in the picture is not from the Ekman faces, but is an example. The individual has given written informed consent, as outlined in the PLOS consent form, to publication of their photograph. cC = congruent trial preceded by a congruent trial, cI = incongruent trial preceded by a congruent trial, iC = congruent trial preceded by an incongruent trial, iI = incongruent trial preceded by an incongruent trial.
Figure 2.
Event-related potential waveforms for midline electrodes and sensor layout.
a) Grand average waveforms depicting ERP activity at Fz (top), Cz (middle), and Pz (bottom). b) Sensor layout of the 128-channel geodesic sensor net. Solid-line circle indicates centro-parietal recording sites averaged for the early and late P3-like components. cC = congruent trial preceded by a congruent trial, cI = incongruent trial preceded by a congruent trial, iC = congruent trial preceded by an incongruent trial, iI = incongruent trial preceded by an incongruent trial.
Figure 3.
Event-related potential waveforms and source localization.
a) Grand average waveforms depicting P3 activity average across six centro-parietal recording sites as a function of previous- and current-trial congruency. Dotted lines indicate time windows used to extract the early and late P3 activity. b) Portion of P3 captured by temporal factor 1 spatial factor 3 (TF1SF3) as a function of previous- and current-trial congruency and extracted from activity at CPz. c) Sagittal view of dipole source for TF1SF3. d) Voltage map for TF1SF3 iI minus cI activity. cC = congruent trial preceded by a congruent trial, cI = incongruent trial preceded by a congruent trial, iC = congruent trial preceded by an incongruent trial, iI = incongruent trial preceded by an incongruent trial.
