Fig. 3 mit Unterschrift: „Stimulus and task for Experiment 2.1. Subjects were initially presented with the Rubin’s ambiguous vase–face stimulus and instructed to indicate alternations in perception between the vase and faces by button presses. Since the periods of spontaneous perceptual dominance were short compared with the time constant of the BOLD response, we designed an event-related paradigm in which the sudden onset of perception of either (a) the faces or (b) the vase was prolonged by adding subtle local contrast gradients (embossing) to one edge or other of the figure–ground boundary. In (a), following a vase-to-faces transition, the standard image was replaced by an embossed-face version of the same stimulus, whereas in (b), subsequent to a faces-to-vase change, an embossed-vase version replaced the standard.“
