a Example of an audiovisual object, producing a sound during a squeezing animation. b Nine audiovisual objects, resulting from the unique combination of size and sound, are labelled with abstract names that participants learn during the course of a behavioural training. c In our bidimensional conceptual space, there are 16 possible directions between two words. d Examples of trials during the comparison task. For each trial, two words are presented in rapid sequence, and participants are instructed to think about how both the perceptual features implied by the object names changed. This was conceivable as a linear trajectory in the bidimensional conceptual space.
