    J Vis 6:1087-92. 2006

    Perception 36:1043-8. 2007

    Perception 35:959-64. 2006

    Perception 30:785-94. 2001
    ..A plaid surround can induce 2-D illusions that modulate the apparent direction, not just the speed, of moving squares. Thus, the motion salience of a moving edge depends critically on its instantaneous contrast against the background...
