In order to explore whether there was any relationship between the two gradients, we calculated the Pearson correlation between the generalization of acquisition (difference score between the last acquisition trial and the first extinction trial)
and the generalization of extinction (difference score between the first test trial and the last extinction trial). This analysis yielded a significant correlation, r = .25, p < .05 (two-tailed) and showed that those participants who displayed stronger generalization of acquisition were also likely to show stronger generalization of extinction.
