In the learning phase, thirty-nine participants learned to associate cues with yoghurt drinks. Cues were learned for mildly and highly salty and sweet yoghurts.

In the test phase a cue was presented to participants subliminally (20ms) or supraliminally (500ms) before they tasted and rated liking of one of three yoghurt drinks in each category. The three yoghurt drinks consisted of the trained samples and a new third drink situated approximately half-way in between. The cue-drink combination was …
