Cue recruitment

Cue recruitment was demonstrated by Haijiang et al. (2006) using a computer-generated rotating Necker cube stimulus. This stimulus is perceptually bistable and may appear to rotate either left or right. To test for cue recruitment, binocular disparity cues (3D cues) were added to the Necker cube, to specify which part of the cube was in front and which was in back. The apparent direction of rotation was thereby brought under experimenter control. The new cue was that the cube moved upward or downward on every trial (contingent on its direction of rotation). Test trials contained the new cue but not the trusted cue. On these trials, trainees tended to see the cube rotating in the same direction it had during training (depending on whether its motion was upward or downward). == External links and references ==
