This article comprehensively examines how information processing relates to attention and consciousness. We argue that no current theoretical framework investigating consciousness has a satisfactory and holistic account of their informational relationship. Our key theoretical contribution is showing how the dissociation between consciousness and attention must be understood in informational terms in order to make the debate scientifically sound. No current theories clarify the difference between attention and consciousness in terms of information. We conclude with two proposals to advance the debate. (...) First, neurobiological homeostatic processes need to be more explicitly associated with conscious information processing, since information processed through attention is algorithmic, rather than being homeostatic. Second, to understand subjectivity in informational terms, we must define information uniqueness in consciousness (e.g., irreproducible information, biologically encrypted information). These approaches could help cognitive scientists better understand conflicting accounts of the neural correlates of consciousness and work toward a more unified theoretical framework. (shrink)

It appears that consciousness science is progressing soundly, in particular in its search for the neural correlates of consciousness. There are two main approaches to this search, one is content-based (focusing on the contrast between conscious perception of, e.g., faces vs. houses), the other is state-based (focusing on overall conscious states, e.g., the contrast between dreamless sleep vs. the awake state). Methodological and conceptual considerations of a number of concrete studies show that both approaches are problematic: the content-based approach seems (...) to set aside crucial aspects of consciousness; and the state-based approach seems over-inclusive in a way that is hard to rectify without losing sight of the crucial conscious-unconscious contrast. Consequently, the search for the neural correlates of consciousness is in need of new experimental paradigms. (shrink)

It is widely held that there is an important distinction between the notion of consciousness as it is applied to creatures and, on the other hand, the notion of consciousness as it applies to mental states. McBride has recently argued in this journal that whilst there may be a grammatical distinction between state consciousness and creature consciousness, there is no parallel ontological distinction. It is argued here that whilst state consciousness and creature consciousness are indeed related, they are distinct properties. (...) Conscious creatures can have, at one time, both conscious and unconscious mental states. This raises the question of what distinguishes the conscious from unconscious mental states of a subject: a question about what state consciousness consists in. Whilst the state/creature distinction may not be of use in explaining every aspect of a subject's consciousness, it does provide a key part of the explanandum for theories of consciousness and mind. The state/creature consciousness distinction is a real one and should not be dropped from our psychological taxonomy. (shrink)

Abstract: “Consciousness” seems to be a polysemic, ambiguous, term. Because of this, theorists have sought to distinguish the different kinds of phenomena that “consciousness” denotes, leading to a proliferation of terms for different kinds of consciousness. However, some philosophers—univocalists about consciousness—argue that “consciousness” is not polysemic or ambiguous. By drawing upon the history of philosophy and psychology, and some resources from semantic theory, univocalism about consciousness is shown to be implausible. This finding is important, for if we accept the univocalist (...) account then we are less likely to subject our thought and talk about the mind to the kind of critical analysis that it needs. The exploration of the semantics of “consciousness” offered here, by way of contrast, clarifies and fine-tunes our thought and talk about consciousness and conscious mentality and explains why “consciousness” means what it does, and why it means a number of different, but related, things.
