Figures & data
Figure 1 Illustration of the experimental trial structure.
Figure 2 Mean ratings of the degree of willingness-to-pay across four conditions.
Figure 3 Grand mean ERP waveforms elicited by four conditions at Pz electrode site. Black-dotted rectangles indicated the time window used for statistical analysis and the arrow indicated the LPP component.
Figure 4 Scalp distributions of the low price minus high price difference waves under the positive and negative rating conditions in the 500–1000 ms.
Figure 5 The spectrogram at each time-frequency point at Pz electrode site in four conditions.
Figure 6 The spectrogram of the positive and negative rating conditions (average across different price) at Pz electrode site, and the topography of the alpha-ERD from 8 to 13 Hz in the time windows of 500–1000 ms and 1000–1500 ms.
