Book outline[ edit ] Introduction: The Stuff of Thought[ edit ] Dehaene reviews historical intuitions that consciousness must be separate from matter. He explains how consciousness was not even mentioned in neuroscientific circles until the late s, when a revolution in consciousness research began. Dehaene believes that "access consciousness" being aware of and able to report on information is the right definition to start with for scientific investigation. While some philosophers insist that access consciousness differs from "phenomenal consciousness" e. He introduces the project of measuring neural correlates of consciousness using paradigms like minimal contrasts of images, masking subliminal stimuli , binocular rivalry , and attentional blink.

The attentional blink relates to the psychological refractory period , inattentional blindness , and change blindness. Olaf Blanke 's studies on out-of-body experiences explore an example where conscious experience changes while external stimuli stay the same. In Ch. Dehaene is most interested in neural signatures of consciousness that represent the consciousness brain processing itself. Dehaene discusses a debate over whether meaning can be processed unconsciously and concludes based on his own research that it can be.

Chapter 05 - Variations In Consciousness
An N meaning-based wave occurs for unexpected words even when masked or not attended to. Unconscious processing is not just bottom-up but can be enhanced when top-down attention is directed toward a target, even if the target never becomes conscious. Brains can even do some mathematical operations unconsciously, and sitting on a problem to let the unconscious mind work out an answer has proved helpful in several experiments. Convergence on a single interpretation of local receptive-field data does not occur under anesthesia. Creating lasting thoughts that can remain in working memory for use at a later time. Daniel Dennett compares this with an echo chamber.

In contrast, unconscious information decays away exponentially within about a second. Consciousness seems "to collect the information from various processors, synthesize it, and then broadcast the result -- a conscious symbol -- to other, arbitrarily selected processors" p. This resembles a production system in artificial intelligence. Sharing the contents of our minds with others, via language and non-verbal signals. Brains can make confidence assessments in their opinions, which helps with combining judgments optimally.

Unconscious perception is like a wave that peters out upon reaching shore, while conscious perception is more like an avalanche that gains momentum as it progresses. Ignition of a late P3 wave when a word is consciously seen but not when it remains unconscious. Dehaene compares conscious perception to breaking "through the dike of the frontal and parietal networks, suddenly flooding into a much larger expanse of cortex" p. There are actually two P3 waves, and they seem to occupy bandwidth that prevents comprehension of other stimuli at the same time, which explains the attentional blink and the serial nature of consciousness. A marked increase in the power of gamma waves starting at about milliseconds after a stimulus.

Contrary to an initial hypothesis by Francis Crick and Christof Koch , gamma waves around 40 Hz do not appear only during consciousness. But when they show up in unconscious processing, they do have a much reduced intensity. Brain-wide synchronization of information in what's called a "brain web". Granger causality analysis shows strong bidirectional causality, with signals traveling both bottom-up to relay sensory information to higher areas and top-down perhaps as attention or confirmation signals. Consciousness seems to have a "tipping point" or "phase transition" of sorts, an all-or-nothing cutoff. Dehaene uses the phrase "global ignition" to describe the process of neurons bursting into widespread activation, similar to the way an audience begins with a few claps and then erupts into synchronous applause p.

Consciousness is slower than events in the external world. The flash lag illusion illustrates this because we can predict future positions of moving objects but not those of objects that suddenly appear. Conscious percepts have properties of "stability over time, reproducibility across trials, and invariance over superficial changes that leave the content intact" p. To prove causation between brain states and conscious experiences, neuroscientists have used transcranial magnetic stimulation and intracranial electrodes for patients undergoing surgery to directly create perceptions.

An example is phosphene. Dehaene proposes that "When we say that we are aware of a certain piece of information, what we mean is just this: the information has entered into a specific storage area that makes it available to the rest of the brain" p. He adds: "The flexible dissemination of information, I argue, is a characteristic property of the conscious state" p. Dehaene and colleagues have developed computer simulations of neural dynamics that successfully replicate the way in which distributed processing at the brain's periphery gives way to a stable, serial "thought" at higher levels due to feedback amplification of one signal and inhibition of others. The simulation showed the four signatures of consciousness described in Ch. Consciousness seemed to behave like a "phase transition" between one unconscious stable state of low-level activity and another conscious state consisting of snowballing self-amplification and reverberation p.

Subliminal stimuli fail to become conscious because by the time the higher layers try to amplify the signal, the original input stimulation has vanished p. Dehaene suggests that noise fluctuations in neural activity can be amplified and give rise to randomness in our streams of thought p. Recent findings have shown that a few patients without any ability to move not even to move their eyes still show intact consciousness as seen by their ability to answer questions in an fMRI. The trick is to instruct the patients to think about their apartments if they want to say "no" and about playing tennis if they want to say "yes", and the corresponding differences in brain activity can be observed. Different tests can give different answers regarding whether a clinical patient is conscious, and responses may depend on time of day or other factors. Hence, Dehaene suggests "to develop a whole battery" of tests that can be applied in many contexts pp.

Dehaene suggests that computers could become more like animal brains if they had greater communication between processes, more learning plasticity, and more autonomy over decisions. Of these design changes, he suggests that "at least in principle, I see no reason why they would not lead to an artificial consciousness" p. Dehaene suggests that the hard problem of consciousness "just seems hard because it engages ill-defined intuitions", and it "will evaporate" as people better understand "cognitive neuroscience and computer simulations" p. Dehaene also defends a compatibilist notion of free will and suggests even that free will "can be implemented in a standard computer" p.

Reactions[ edit ] James W. Kalat thinks "Consciousness and the Brain is beautifully written, erudite, thoughtful, and likely to provoke discussion for years to come. However, Kalat suggests that this leaves us with a puzzle: "Unless we assume that computers are conscious, the question remains why we are conscious when we perform certain functions, whereas computers can perform virtually the same functions without consciousness. That said, he appreciates Dehaene's book and recommends to "read a chapter at a time because it is jam-packed with intuition-altering experiments. Like Kalat, Hutson finds Dehaene's dismissal of the hard problem unjustified because consciousness is "unique" in being "inherently private, subjective", unlike other phenomena that can be reductively explained.

If the computer had passed the Turing test this way, it follows, says Searle, that he would do so as well, simply by running the program manually. Searle asserts that there is no essential difference between the roles of the computer and himself in the experiment. Each simply follows a program, step-by-step, producing a behavior which is then interpreted by the user as demonstrating intelligent conversation. However, Searle himself would not be able to understand the conversation. Therefore, he argues, it follows that the computer would not be able to understand the conversation either. Searle argues that, without "understanding" or " intentionality " , we cannot describe what the machine is doing as "thinking" and, since it does not think, it does not have a "mind" in anything like the normal sense of the word.

It is a challenge to functionalism and the computational theory of mind , [g] and is related to such questions as the mind—body problem , the problem of other minds , the symbol-grounding problem, and the hard problem of consciousness. Searle writes that "according to Strong AI, the correct simulation really is a mind. According to Weak AI, the correct simulation is a model of the mind. For example, in , AI founder Herbert A. Simon declared that "there are now in the world machines that think, that learn and create". This is not science fiction, but real science, based on a theoretical conception as deep as it is daring: namely, we are, at root, computers ourselves.

Because a computer program can accurately represent functional relationships as relationships between symbols, a computer can have mental phenomena if it runs the right program, according to functionalism. Stevan Harnad argues that Searle's depictions of strong AI can be reformulated as "recognizable tenets of computationalism, a position unlike "strong AI" that is actually held by many thinkers, and hence one worth refuting. Each of the following, according to Harnad, is a "tenet" of computationalism: [35] Mental states are computational states which is why computers can have mental states and help to explain the mind ; Computational states are implementation-independent —in other words, it is the software that determines the computational state, not the hardware which is why the brain, being hardware, is irrelevant ; and that Since implementation is unimportant, the only empirical data that matters is how the system functions; hence the Turing test is definitive.

Strong AI vs. He writes "brains cause minds" [6] and that "actual human mental phenomena [are] dependent on actual physical—chemical properties of actual human brains". If neuroscience is able to isolate the mechanical process that gives rise to consciousness, then Searle grants that it may be possible to create machines that have consciousness and understanding. However, without the specific machinery required, Searle does not believe that consciousness can occur. Biological naturalism implies that one cannot determine if the experience of consciousness is occurring merely by examining how a system functions, because the specific machinery of the brain is essential.

Thus, biological naturalism is directly opposed to both behaviorism and functionalism including "computer functionalism" or "strong AI". Indeed, Searle accuses strong AI of dualism, writing that "strong AI only makes sense given the dualistic assumption that, where the mind is concerned, the brain doesn't matter. However, in more recent presentations Searle has included consciousness as the real target of the argument. The computational model for consciousness stands to consciousness in the same way the computational model of anything stands to the domain being modelled. Nobody supposes that the computational model of rainstorms in London will leave us all wet. But they make the mistake of supposing that the computational model of consciousness is somehow conscious.

It is the same mistake in both cases. Searle, Consciousness and Language, p. The argument, to be clear, is not about whether a machine can be conscious, but about whether it or anything else for that matter can be shown to be conscious. It is plain that any other method of probing the occupant of a Chinese room has the same difficulties in principle as exchanging questions and answers in Chinese. It is simply not possible to divine whether a conscious agency or some clever simulation inhabits the room. The whole point of the thought experiment is to put someone inside the room, where they can directly observe the operations of consciousness. Searle claims that from his vantage point within the room there is nothing he can see that could imaginably give rise to consciousness, other than himself, and clearly he does not have a mind that can speak Chinese. Information could be "down converted" from meaning to symbols, and manipulated symbolically, but moral agency could be undermined if there was inadequate 'up conversion' into meaning.
