On day 1 participants learned up to 80 auditory-visual associations. On day 2, each visual cue was paired with either a rewarding (set 1, monetary reward) or neutral outcome (set 2, woodchip). On day 3, auditory cues were presented in isolation (‘inference test’), without visual cues or outcomes, and we measured evidence for inference from the auditory cues to the appropriate outcome. Participants performed the inference test in an MRI scanner where fMRI-fMRS data was acquired. After the MRI scan, participants completed a surprise ­associative test for auditory-visual associations learned on day 1
