ABSTRACT

Experimental studies of perception without awareness can be traced to the very beginnings of psychology in North America (see Merikle, 1992). In fact, Kihlstrom, Barnhardt, and Tataryn (1992) suggested that the first published study from the first psychological laboratory in North America at Johns Hopkins University was Peirce and Jastrow’s (1884) demonstration that it is possible to perceive small differences in pressure on the skin without any subjective awareness of different sensations. However, despite its relatively long history, research on perception without awareness has been plagued by continual controversy.
