From: Temporal perceptual learning distinguishes between empty and filled intervals
The transfer effects of four conditions for the empty-interval (EI) group (a) and the filled-interval (FI) group (b). The learning index (LI) is defined as the percentage change in the pre-test threshold (i.e. (pre–post)/pre threshold). A positive LI value indicates improvement after training. The red and blue bars indicate the trained condition for each group whereas the other three grey bars represent the untrained conditions. Dots signify individual learning indices. Error bars specify between-subject standard errors (s.e.m.). The asterisks on each bar denote significant results from one-sided, one-sample t-tests with Bonferroni corrections. *p < .05, **p < 0.01, ***p < 0.001.
