    Change blindness is a failure of explicitly detecting changes between consecutively presented images when separated, e.g., by a brief blank screen. There is a growing body of evidence of implicit detection of even explicitly undetectable changes, pointing to the possibility of the implicit change detection as a prerequisite for its explicit counterpart. We recorded event-related potentials (ERPs) of the electroencephalography in adults during an oddball-variant of change blindness flicker paradigm. In this variant, rare pictures with a change were interspersed with (...)

    A number of theories of consciousness define consciousness by the folk-intuition that consciousness is somehow aware of, or ‘given’ to itself. I attempt to undermine this intuition on phenomenological, conceptual and psychological grounds. An alternative, first-order theory of consciousness, however, faces the task of explaining the possibility of self-awareness for consciousness, as well as the everyday intuition supporting it. I propose that another, weaker kind of givenness, ‘givenness as availability’, is up to both of these tasks, and is therefore sufficient (...)
