Consciousness Online: Hakwan Lau on the Higher-Order Theory of Consciousness
Hakwan Lau, a cognitive neuroscientist at Columbia University and the Donders Institute, is interested in empirically testing philosophical theories of consciousness. In this talk he presents the results of his experiments that provide support for the higher-order theory of consciousness. Roughly speaking, this is the view that ordinary consciousness arises as the result of our awareness of ourselves as being in our own mental states.

Lau presents the results of his 2006 paper with Dick Passingham at Oxford. In these studies they produce a blind-sight like condition in normal subjects. That is to say that these subjects are good at detecting whether a stimulus was a square or a diamond, but in some cases reported that they were merely guessing. Because they used a masking paradigm they were able to find conditions where subjects were equally good at detecting the stimulus, but in one case said they were guessing whereas in the other case they said they clearly saw the stimulus.
When put in the scanner it was activity in the dorsal lateral prefrontal cortex that was active when subjects said the stimulus was clearly visible, and was relatively deactivated when the subjects reported they were merely guessing.
Lau also considers and rebuts objections.

ABOUT Consciousness Online
The Online Consciousness Conference was founded and is organized by Richard Brown and is dedicated to the rigorous study of consciousness and mind. I construe consciousness studies very broadly so as to include philosophy of mind, psychology, neuroscience, cognitive science, linguistics, neurophilosophy, and even some philosophy of language! Basically, if it relates to the mind then it relates to consciousness.
The goal is to bring philosophers, scientists, and interested lay persons together in an online venue to promote high-level discussion and exchanging of views, ideas and data related to the scientific and philosophical study of consciousness and mind. A subsidiary goal is to promote and facilitate interaction between online venues and traditional print venues.
About Founder, Richard Brown, PhD
I am a philosopher at the City University of New York. In particular I am an Associate Professor in the Philosophy Program at LaGuardia Community College. I earned my PhD in Philosophy with a concentration in Cognitive Science from the Graduate Center in 2008. My work is focused on the philosophy of mind, consciousness studies, and the foundations of cognitive science but I also have interests and projects in the philosophy of language, metaethics, logic and the philosophy of logic, as well as the history of philosophy.
