Fig. 3.

Trial rules were the same as in Experiment 1. There were three kinds of trial blocks. a 3-trial episodes were created by having small iTi within the episode and large iTi across episode boundaries. This was further reinforced by a faded digit in the background that went from 3 to 1 across the 3 trials making up the episode. b 5-trial episodes were similar to the 3 trial episodes, except that they consisted of 5 trials, and the faded background digit went from 5 to 1 across them. c Trials of the independent trial blocks were presented in a flat sequence with constant iTi and had the digit ‘1’ in their background that remained the same throughout the block.
