Applied a theory of information integration to decision making with probabilistic events. 10 undergraduates judged the subjective worth of duplex bets that included independent gain and lose components. The worth of each component was assumed to be the product of a subjective weight that reflected the probability of winning or losing, and the subjective worth of the money to be won or lost. The total worth of the bet was the sum of the worths of the 2 components. Thus, each (...) judgment required multiplying and adding operations. The multiplying model worked quite well in 4 experimental conditions. The adding model showed more serious discrepancies, though these were small in magnitude. The theory of functional measurement was applied to scale the subjective values of the probability and money stimuli. Subjective and objective values were nonlinearly related both for probability and for money. (shrink)

Roots presents articles on landmark discoveries that laid the basis for contemporary molecular and cellular biology. In this article, N. H. Horowitz, Professor Emeritus at the California Institute of Technology, and a former associate of George Beadle's, reviews the work that led to the one gene–one enzyme hypothesis.

My suggestion that the H.A. was written during the reign of the Emperor Julian and in his interest has had, on the whole, ‘a bad press.’ Reviewers who have not thought it necessary to support with argument their doubts or their rejection of the theory are in a strong position: they remain practically unassailable. ‘The theory seems on a priori grounds improbable:’ a historical student can only reply that so is human nature—distressingly improbable, as he knows to his cost. ‘After (...) reading this book one puts it down “met een zekere onvoldaanheid:”’ what can an author do save express his regret for having caused Dr. Van de Weerd this discomfort? But two stalwart defenders of the conservative position—De Sanctis and Lécrivain’—have sustained with detailed argument their unqualified rejection of my theory; in their cases it is possible to attempt a rejoinder.

The function of memory is to allow past experience to subserve present goal-oriented thought and action. The defining characteristic of goal-oriented approach/avoidance is value. Value lies beyond the reproductive conception of memory that is basic to both metaphors discussed in Koriat & Goldsmith's target article. Functional memory requires a quite different metaphor, for which a grounded theory is available.

Even after the masterly studies of Leo Sternbach following on the paper by Hilberg1 there are still some small points to be noted on the historical poems of George of Pisidia. In what follows I have, of course, presupposed a knowledge of Sternbach's work which has happily rendered superfluous the new text which he was to have edited for Methuen's Series of Byzantine Texts.

Who was the author of the Fourth Edict in the great persecution of Diocletian's reign we do not know. Its precise terms are not recorded; of the date of its issue we are not informed. It is true that Mr. Kidd has recently written: ‘On April 30, 304, Maximian put out the Fourth Edict in the name of himself and bis co-Augustus,’ but he discreetly forbears to give the reader any hint of the source on which he bases that statement. (...) It may be doubted whether he has any better authority in mind than the ambiguous Passio S. Sabini, which, as even Mr. Mason admitted many years ago, ‘is not in the highest class of the historical relics of its age.’ If, indeed, this supposition does not do Mr. Kidd an injustice, it would have been well to have given some reasoned defence of the document. Dufourcq regards the Passio S. Sabini as a product of the Ostrogothic period, and contends that its picturesque exordium does not depend upon any earlier source. Until his detailed criticism of the Passion is answered, we can hardly use it for the reconstruction of the history of the fourth century. (shrink)

Bullot & Reber (B&R) put forth a design stance to fuse psychological and art historical accounts of visual thinking into a single theory. We argue that this aspect of their proposal needs further fine-tuning. Issues of transgression and coherence are necessary to provide stability to the design stance. We advocate looking to Art Education for such fundamentals of picture understanding.
