Under what circumstances does the brain devote resources to only the “when” of sensory events? @ChuckSherrington - Btw on my profile page here there's a link to my webpage, from which you can find the main page of the lab group I belong to. We put published papers online, so you can find some stuff to download, but we're a fairly new group, so not so many publications yet. The group is called 'Prediction and attention' - there might be a few things directly interesting to you. |

Under what circumstances does the brain devote resources to only the “when” of sensory events? @ChuckSherrington: I just got back from holidays and put the Arnal paper in my bag to read while commuting, with this topic in mind :) I'll get back to it soon. In the meantime, the book 'On Intelligence' by Jeff Hawkins is a very good introduction into the brain as a predictive machine. I'm not sure how deep you want to go, and in what direction exactly. I don't know much about timing, and reading myself into this literature is the plan for the next half year. I hear that Kia Nobre has many papers on the subject. |

Are intelligence scores correlated with detection of second stimulus in an Attentional Blink test? I would be surprised if it doesn't correlate. Intelligence scores tend to correlate with almost any cognitive ability. Perhaps you might want to look up John Duncan's work. He's an attention researcher who also published a bit in the intelligence field. I haven't read the key paper myself, but here it is |

Under what circumstances does the brain devote resources to only the “when” of sensory events? Hm, I now realize you're assuming more resources are put into processing something predictable, so my leaky faucet is the exact opposite of what you're asking. In general, there is more neural activity to unpredictable events, i.e. more resources are used. I'll get back to your question once I read Arnal's new paper! |

Under what circumstances does the brain devote resources to only the “when” of sensory events? Presumably when the 'what' is entirely predictable, but the 'when' is not? Like the oh so annoying sound of a dripping faucet :) Would that be an example? I'm not entirely clear what the question is though, but I plan to read this paper in the near future and then it might become clear. I don't think you can ever shut down the 'what' completely though. There's always an input layer (i.e. prediction error layer) which gets excited, and subsequently dampened before progressing to the next stage of processing. But it does get excited on input. |

What are current neuronal explanations and models of 'consciousness'? I think it's a good question, especially since "Consciousness Explained" was written 20 years ago, and a lot of research happened in between. I don't have time to do searches at the moment, so I'll just tell you in this comment (and you can search further) that one model of consciousness, forwarded by Victor Lamme, embraces the idea that recurrent connections between brain areas are the main NCC. I'll write more if I find the time. |

Free online intelligence test with norm table, high reliability, and must be printable? I don't know the assumptions for this test, but if standard assumptions hold, I think it can be used for the intended purpose. Normally, all questions have equal weight, the average score is 100 IQ points, and each IQ point equals 1/15th of a standard deviation of the distribution. This test will give you a total score in IQ points as well as a percentile score, so you can check if these assumptions are true. |
