Figure 4
(a) Scatterplot of trial-by-trial decoding success rates, calculated for each participant (Y-axis), and the average subjective ratings given to imagined experiences on visual imagination trials (X-axis). Blue text relates to statistical tests for a correlation between trial-by-trial decoding success rates and the subjective intensity of imagined experiences, whereas red text relates to statistical tests comparing actual decoding success rates to a chance decoding success rate (33.3%, marked by the black horizontal line). (b) Details are as for Fig. 4a, but analyses relate to average subjective ratings given to imagined experiences on audio imagination trials. (c) Pie chart showing the proportion of participants for whom the experimental condition (imagined Visual, Audio or Resting-State trials) could be decoded on a trial-by-trial basis, from analyses of the PSD of their brain activity, at a rate that was statistically above chance (established via a non-parametric shuffle test, see main text for further details). (d) Decoding Confusion Matrix, depicting proportions of decoded trials averaged across participants as a colour map, X-axis denotes actual experimental conditions and Y-axis the decoded conditions.
