The Limits and Possibilities of Unconscious Processing

The existence of unconscious perception is largely acknowledged. However, the limits and possibilities of unconscious processing remain unclear. We used two different approaches to clarify this. First, we conducted a large-scale meta-analysis of masked priming studies to examine the depth of unconscious processing. Second, we contrasted a manipulation on a conscious versus an unconscious level in order to shed light on whether unconscious processing extends to high cognitive levels, similar to conscious processing.
