CogSci-94 titles, authors, and abstracts can be searched on http://www.gatech.edu/cogsci/cogsci.html. Registration info is also there, or contact cogsci94@cc.gatech.edu. [Ashwin Ram (ashwin@cc.gatech.edu), comp.ai, 6/2/94. David Joslin.]

There is evidence that highly rated chess players are orderly, unconventional (possibly rebellious), able to concentrate deeply, and -- at the top ranks -- suspicious. A. Avani et al., Personality and Individual Differences, 8, 715-719, 1986. Masters and grandmasters apparently expand their search following a negative position evaluation and narrow it following a positive evaluation. R. Reynolds, Bulletin of the Psychonomic Society, 29 (1), 55-56, 1991. [John Rummel (cpropper@facstaff.wisc.edu), rec.games.chess, 6/6/94.] (Rummel is circulating an annotated bibliography for a paper that he is working on.)

"It is commonly believed that qualified chess playing requires the player to be intelligent, to have an outstanding memory, and in addition, that chess has educational benefits and develops a systematic, rational thinking. These views have no solid empirical support." -- A. Avni, Psychological Reports, 67, 899-906, 1990. [John Rummel (cpropper@facstaff.wisc.edu), rec.games.chess, 6/6/94.]

"Well, allow me to introduce myself to you as an advocate of Ornamental Knowledge. You like the mind to be a neat machine, equipped to work efficiently, if narrowly, and with no extra bits or useless parts. I like the mind to be a dustbin of scraps of brilliant fabric, odd gems, worthless but fascinating curiosities, tinsel, quaint bits of carving, and a reasonable amount of healthy dirt. Shake the machine and it goes out of order; shake the dustbin and it adjusts itself beautifully to its new position." -- Robertson Davies, "Tempest-Tost." [Andrew Kuchling (fnord@cs.mcgill.ca), alt.quotations, 10/8/93.]

Hypothetical information processing within microtubules is discussed in Discover (6/94, p. 89). Roger Penrose sees microtubules as channels for the quantum computations that he postulated in "The Emperor's New Mind." The tubules may offer a quiet "quantum" environment within the chaos of normal cell activity. Stuart Hameroff has been studying microtubules since the early 1970s. Their molecular blocks have "slots" for "sliding" electrons. Anesthetics that affect consciousness freeze these electrons in place, but the mechanism is not understood. [David H. Freedman.] (Wild speculation: The calm, out-of-body state induced by drugs, near-death experience, oxygen deprivation, or meditation might reveal computation and cognitive models within the microtubular system. In normal consciousness, these models would be synchronized with sensory inputs carried in nerve impulses. Protozoa could have evolve computational or state-recording elements prior to the evolution of neurons and synaptic meshes, and these microtubular mechanisms would have co-evolved with neural intelligence.)

"Consciousness is mysterious. Quantum mechanics is mysterious. By the Law of Minimization of Mystery, if you find two mysteries, maybe they are the same." -- David Chalmers, 4/17/94. [Steve Potter (spotter @druggist.gg.caltech.edu), Neuron Digest, 5/30/94.]
