Schematic description of three masked priming methods for which objective direct measures have demonstrated prime invisibility or inaudibility. (a) Visual word repetition priming across case (Dehaene et al. 2001). (b) Repetition priming for faces (Kouider et al. submitted). Masks are made of overlaid and reversed faces and the prime size is reduced by 80% when compared with the target. (c) Repetition priming for spoken words (Kouider & Dupoux 2005). Masks made from backward speech and the prime are attenuated (−15 dB) and time compressed to 35% of their original duration.
