LJ As a result, no putative cases of unconscious perception can hope to avoid the familiar concern that they simply involve weak conscious awareness unreported due to a conservative response criterion (Eriksen 1960; Holender 1986; Phillips 2016; Peters, this symposium).

NA This means the “conscious” condition should not present a large, bright, leisurely stimulus, while the “unconscious” condition uses a small, dim, brief stimulus. In meta-contrast masking the stimulus, in our case a colored disc, is presented very briefly followed after a short interval by a ring whose inner edge coincides with the location that had been the outer edge of the disc. x�U���0 �~�u��"q4����D�R�Vi���������r�AA^#&���8��^C 44 0 obj The color of the disc is the same on all trials. endobj endobj 129 0 obj 42 0 obj 38: 2012: Why does the universe exist?

Yet this test for perception is equivalent to so-called “objective” measures of consciousness (i.e., above chance discriminative sensitivity) (Green and Swets 1966).
