1 Of the eight synaesthetes, only two showed a significant interaction (S1 and S6, p < .05), with another showing a strong trend (S8, p = .058).

Intriguingly, there was also a trend for an overall advantage for synaesthetes over controls when the shape was defined by display colour ( Figure 4 implies that this may be due to differences at the middle set sizes, but there is only a weak trend for an interaction, so we are not able to analyse this statistically).
