Our target article, “Insects have the capacity for subjective experience,” has provoked a diverse range of commentaries. In this response we have collated what we see as the major themes of the discussion. It is clear that we differ from some commentators in our commitments to what subjective experience is and what the midbrain is capable of. Here we clarify where we stand on those points and...
Rapid progress in artificial intelligence (AI) capabilities has drawn fresh attention to the prospect of consciousness in AI. There is an urgent need for rigorous methods to assess AI systems for consciousness, but significant uncertainty about relevant issues in consciousness science. We present a method for assessing AI systems for consciousness that involves exploring what follows from...
An increasing number of authors are willing to attribute phenomenal consciousness to relatively simple organisms like insects. Yet it is not at all clear what functional role the substrates of consciousness would play. Here, we argue phenomenal consciousness is a consequence of how mobile animals with spatial senses and a capacity for goal-directed behaviour resolve the complex problem of...
Claims that an AI system "instantiates" a consciousness- or cognition-theoretic construct are often supported by a cheap correlate: aggregate dependence read as irreducible integration, ordinary shared-store efficiency read as global access, or a confidence-labelled signal read as metacognitive monitoring. Such inferences trade on a construct's appearance while omitting the property that...
Whether current or near-term AI systems could be conscious is a topic of scientific interest and increasing public concern. This report argues for, and exemplifies, a rigorous and empirically grounded approach to AI consciousness: assessing existing AI systems in detail, in light of our best-supported neuroscientific theories of consciousness. We survey several prominent scientific theories of...
For the materialist, the hard problem is fundamentally an explanatory problem. Solving it requires explaining why the relationship between brain and experience is the way it is and not some other way. We use the tools of the interventionist theory of explanation to show how a systematic experimental project could help move beyond the hard problem. Key to this project is the development of...
Video games are a kind of physical computation, and the point holds true of computation more generally. Computationalism about consciousness is the thesis that phenomenal properties supervene on computational ones – that is, that being the right kind of computer is enough to be conscious. The mechanism of action of inhalational anesthetics remains something of a scientific puzzle, especially...
How, why, and when consciousness evolved remain hotly debated topics. Addressing these issues requires considering the distribution of consciousness across the animal phylogenetic tree. Here we propose that at least one invertebrate clade, the insects, has a capacity for the most basic aspect of consciousness: subjective experience. In vertebrates the capacity for subjective experience is...
Kohler's experiments with inverting goggles are often thought to support enactivism by showing that visual re-inversion occurs simultaneous with the return of sensorimotor skill. Closer examination reveals that Kohler's work does not show this. Recent work by Linden et al. shows that re-inversion, if it occurs at all, does not occur when the enactivist predicts. As such, the empirical evidence...
