Unformatted text preview: s of it occurring. Like the blindsight patient who
was ﬂashed a light and could move their eyes to that light, even though had no idea
of what they were doing. So their conscious awareness was absent, but still getting
that information in some way. How active does the PFC have to be, to have
conscious awareness? Blindsight:!
Residual visual abilities within a visual
ﬁeld defect (scotoma) in the absence of
Fendrich, Wessinger, & Gazzaniga (1992) Neural Correlates of Consciousness!
Unilateral Spatial Neglect!
A behavioral pattern exhibited by
neurological patients with lesions to the
parietal lobe (usually in the right
hemisphere), in which they fail or are slow
in acknowledging objects or events in the
hemispace opposite their lesion.! Either something grabs our attention or directs our attention is some way. Lot of things that occur outside
of out conscious awareness. Just like the change-blindness awareness studies, where things could be
changing right in front of you and we don't notice it until we direct our attention there, a little higher order
Neglect patients are not blind in that part of the visual ﬁeld, but neglect it, and don't pay attention to it. That
could be a form of consciousness as well; that you have to focus on something and bring it in before you
become consciously aware of it, and work on it and keep it in mind. Have cogntive control outside the
realm of consciousness. Neural Correlates of Consciousness!
When Do We Become Conscious of Our Thoughts?! split-brain patients The interpreter is a left-brain system that seeks explanations for internal and
external events in order to produce appropriate response behaviors.!
Work of Gazziniga = consciousness isn't really isn't really coming about until you start making decisions and rationalizations of what you are doing. For example, Joe, which was ﬂashed to stand up on his left
visual ﬁeld, and he stands up, and not until he is asked about does he realize what he is doing. Its not until we focus our interpreter on...
