Detectionless processing with semantic activation? A footnote to Greenwald, Klinger, and Liu (1989)

Recently published research has suggested that, in a pattern masking task, semantic activation caused by the target may continue to exist even though subjects cannot detect the target. The experiments are reassessed as an exceptional case of the more general rule that subjects are able to use residual semantic activation to actually detect targets. Furthermore, residual graphic information is far less effective at supporting near-chance target detections.
