Functional magnetic resonance imaging (fMRI) paradigm. (A) Timeline of the fMRI experiment. The experiment consisted of four sessions. Each session started with a learning phase, followed by a test phase. Items were presented in blocks. (B) Structure of one learning block. Each learning block consisted of three items, separated by 1 s. (C) Structure of one test block. Each test block consisted of two items, separated by a response window of 2.5 s. After each test item participants responded with a button press, whether the test item was correct with respect to the rule or not.
