 Why think that Stage 3 processing is sufficient for consciousness? Given that Stage 3 processing is not accessible to introspective report, we lack introspective evidence for sufficiency. Lamme appeals to experiments with brief presentation of stimuli such as letters where subjects are said to report seeing more than they can identify in report (Lamme 2010). For example, in George Sperling’s partial report paradigm (Sperling 1960), subjects are briefly presented with an array of 12 letters (e.g., in 300 ms presentations) but are typically able to report only three to four letters even as they claim to see more letters (but see Phillips 2011). It is not clear that this is strong motivation for recurrent processing, since the very fact that subjects can report seeing more letters shows that they have some access to them, just not access to letter identity.
