Binary classification results for each of the eight participants and for each pair of directions. Peak accuracy for the best-classifiable pair of directions is given in brackets after the participant code; this pair is also indicated by a double arrow. Classification scores are depicted for all binary pairings of directions. For each participant, the data consists of six polar plots placed at spatial locations analogous to the locations used in the experiment. Each polar plot contains five pie slices depicting classification accuracies between the location of the plot and each of the five other possible directions. Classification accuracies that are significantly different (p < .05) from chance level (50%) are given as yellow-red pie slices, non-significant accuracies are shaded grey. Both the length of a pie piece and its color indicate classification accuracy (lighter color for higher accuracy, darker color for lower accuracy). For instance, for participant iai, only the top-left and the bottom-right directions could be differentiated from each other significantly.
