This is a précis of a book on frustration theory, whose explanatory domain includes a family of phenomena that have been summarized by the terms dispositional learning and memory-systems that ordinarily have a long-term historical etiology, and in which the learning is relatively reflexive and the memory implicit and not strongly episodic. The book is an… (More)

The role of frustration in learning theory, in the invigoration of behavior and in the development of learned persistence and discrimination learning, is conceptualized. This and other phenomena are facets of the larger explanatory domain of what has come to be known as frustration theory, a theory that has guided the author's own research--from behavioral… (More)

Motivated by the Kerr/CFT conjecture, we explore solutions of vacuum general relativity whose asymptotic behavior agrees with that of the extremal Kerr throat, sometimes called the Near-Horizon Extreme Kerr (NHEK) geometry. We argue that all such solutions are diffeomorphic to the NHEK geometry itself. The logic proceeds in two steps. We first argue that… (More)

We prove that the only four dimensional, stationary, rotating, asymptoti-cally flat vacuum black hole with a single degenerate horizon is given by the extremal Kerr solution. We also prove a similar uniqueness theorem for the extremal Kerr-Newman solution. This closes a longstanding gap in the black hole uniqueness theorems.

The most prominent hypothesis of hippocampal function likens the hippocampus to a "cognitive map," a term used by a famous learning theorist, E. C. Tolman, to explain maze learning. The usual application of this concept of cognitive map, as it applies to the hippocampus, is to what is called spatial learning, mainly in the radial-arm maze of Olton and the… (More)

The recently-conjectured Kerr/CFT correspondence posits a field theory dual to dynamics in the near-horizon region of an extreme Kerr black hole with certain boundary conditions. We construct a boundary stress tensor for this theory via covariant phase space techniques. The structure of the stress tensor indicates that any dual theory is a discrete light… (More)

To my parents, Carlos and Isabel iv Acknowledgements In writing these lines I think of the people without whom I would not be writing these lines. To the person who taught me the inner workings of science, Joe Polchinski, I am deeply grateful. Thank you, Joe, for sharing your knowledge and insight with me, for showing me the way whenever I got off track and… (More)

The behaviorism that cognitive scientists attack is a caricature, drawn primarily from the more polemical writings of J. B. Watson and B. F. Skinner. In this brief commentary, I discuss the fact that these writings, and especially Skinner's, offered the neocognitivists such a polar difference from their own position, that it was easier to ignore the… (More)
