The joint receipt of x and y is the fact of receiving them both. If x and y are objects that are valued, their joint receipt is valued as well. Assumming joint receipt is a binary operation that satisfies the conditions of extensive measurement, there is a numerical representation that is additive over joint receipt. We consider the case where x and y are quantities of the same infinitely divisible good. Different sets of assumptions are explored. Invariance with respect to multiplication proves to be interesting. Invariance with respect to addition yields a linear form. A relaxation of the latter yields an approximately linear form. Finally, we consider a non-commutative but bisymmetric joint-receipt operation with a representation arising from preferences over gambles. 相似文献

In this paper I suggest that much of recent experiment in analytic theory, even widely diverse approaches, has a common denominator the problem of the conceptual vacuum created by the shift away from a central creative position of the idea of psychic mechanisms. I try to illustrate, by comparing theories of Bion and George Klein, that this movement seems to point in the direction of considering now what is uniquely psychoanalytic about our theories. I content that what is unique about psychoanalytic theories is that they are involved in the experiential core-function of the applied science by becoming internalized and used symbolically to aid the analyst inwardly to endure persecutory anxiety and loss of the sense of objective reality, and so maintain the analytic position. 相似文献

ROC curves were determined from response latencies of goldfish in a single-stimulus generalization task. The resulting functions were similar to ROC curves obtained by rating methods with human Os. 相似文献

There has been considerable debate in recent years about the status of “imagery” in problem solving. The present experiment attempts to show that while subjects may employ representational strategies when they first encounter a class of problems, they abandon such strategies as they gain experience with the problems. It does this by asking subjects to answer unexpected questions which are based upon the information which they have just used to solve a problem. The hypothesis, which is supported by the results, is that increasing experience with problems will be paralleled by a decreasing ability to answer unexpected questions. The experiment also shows that such effects are not attributable to a build-up in proactive interference. 相似文献
