| summary | This presentation can be framed in terms of the following theoretical question: is conscious perception necessary and/ or sufficient for conscious perception? I will present a finding in the context of the attentional blink phenomenon that may question the necessity of conscious perception for short-term memory encoding; that is, it may provide evidence that we can encode an item into short-term memory without consciously perceiving that item.
Some would argue that the most interesting aspect of the attentional blink is lag-1 sparing, i.e. the finding that performance on a second target is enhanced if it immediately follows a first in rapid serial visual presentation. We [Bowman&Wyble, 2007; Wyble et al, 2008; Wyble et al, 2011] and others [Hommel & Akyurek; 2005] have argued that at lag-1, the two targets pass into short-term memory together in a single episode. In this talk, I will further provide evidence that, while second target report accuracy is sparred at lag-1, subjective experience is not. That is, we seem to be able to accurately retrieve the second target from memory, even though we had weak, or possibly absent, perception of it.
We also present evidence that the P3 component of the Event Related Potential indexes subjective visibility to a greater extent than it does short-term memory encoding. |
