Cheating: One common morality for gains and losses but two components of morality itself

Previous studies show that decision makers (DMs) lie more to avoid a loss than achieve a gain. Two compelling mechanisms might explain this observation. One assumes that lying is a risky activity and relates to the shape of the monetary value function described by prospect theory, which assumes (a) increased risk taking for loss frames and (b) an asymmetry between the perceived values of losses and gains. The other relates to the importance of self-esteem functions as expressed in self-concept maintenance models, self-esteem issues being weighed against monetary issues. This alternative explanation assumes that a loss frame serves as a factor lowering moral considerations. We report an experimental study presenting sets of lotteries to DMs, once in a moral context and once in a traditional probabilistic context. The results show that DMs take less risk when lotteries are presented in a moral context. It is also shown that DMs take more risk for losses than gains, this holding for both the moral and probabilistic contexts. This latter result suggests that loss/gain asymmetry can be completely explained by prospect theory factors, and framing makes no difference to the valuing of moral considerations.

P-Compatible Hypersubstitution and MP-Solid Varieties

The study of hyperidentities is a growing field of research. While hyperidentities hark back to before 1965 (cf. [1]), they have found a rebirth in the late seventies and early eighties (cf. [8], [9]). It is being expanded in several directions, from connections with clone theory, to finite basis problems, to semigroup theory, to classification of M-solid varieties. Applications to digital logic, formal languages, and hypertext systems have been suggested. The concept of a P-compatible equation, where P is a partition on the set of operation symbols, is a good tool to study the structure of identities. In [4] we asked for P-compatible hyperidentities. In this paper we will consider hypersubstitutions which are compatible with the partition P and will develop a generalized equational theory for certain P-compatible hyperidentities. This revised version was published online in June 2006 with corrections to the Cover Date.     

Magnitude effect contributes to the domain specificity in delay discounting

Discounting is a useful framework for understanding temporal choices. A person who prefers $50 immediately over $100 in 1 month exhibits a higher discount rate than a person deciding to wait for the higher payoff. Although previous research shows that discount rates are domain-specific, we propose an alternative to the domain specificity account. We suggest that differences in discounting alternatives across various domains may result not so much from the domains' nature per se but from differences in perceived attractiveness of the discounted alternatives. We replicated that an illustrative study evidencing domain specificity in discounting (Experiment 1) showed that people's subjective values of the payoffs in domains discounted in this experiment were different (Experiment 2) and used a novel method to match the attractiveness of the available alternatives across domains (Experiment 3). Finally, Experiment 4 showed that when matching was applied, the domain effect disappeared. We conclude that a magnitude effect can, at least partially, explain domain specificity in delay discounting.     

The Structure of Noema in the Process of Objectivation

The subject of the present work is noema and its structure in various stages of the objectivating process. Despite its great importance, this issue has never been adequately explained, neither by Husserl nor by his followers. The main objective is to provide the theory that would describe the structure of noema and its function without simplifying the case or appealing to non-phenomenological data. This has been achieved by way of analysis divided into four sections. The first provides an overview of noema. The second section is devoted to analysis of the process of objectivation, i.e., how an active awareness of the object in a logical sense is constituted by a series of passive experiences. The third section refers to a noema as found at different stages of objectivation. It explains how the increasing level of activity, which turns out to be a noetic function, causes changes to the structure of a noema. The last section summarises the results and stresses the advantages of the developed theory in comparison with other interpretations, especially those offered by Drummond, Smith and McIntyre.     

Pragmatic concepts of valid inference and of implication

Summary The paper gives a tentative reconstruction of the classical theory of so called fallacious arguments. Its title refers to the following observations. One of the fallacies listed in traditional logic ispetitio principii. It seem natural to add to the list another, similar fallacy. An argumentationArg ⁺ considered as a part of a theoretical contextC commits this fallacy relatively toC, if it contains an inference such that the principle of this inference has not been proved inC. By principle of a given inference the conditional is meant whose antecedent and consequent are the conjuction of all the premisses and the conclusion of the inference respectively. If the principle of a given inference has been proved in a given contextC, the inference is valid relatively toC and the premisses are implying the conclusion relatively toC. Both these concepts, of valid inference and of implication do involve the concept of an effectively performed proof; hence they are pragmatic concepts.     

The Nencki Affective Picture System (NAPS): Introduction to a novel,standardized, wide-range,high-quality,realistic picture database

Selecting appropriate stimuli to induce emotional states is essential in affective research. Only a few standardized affective stimulus databases have been created for auditory, language, and visual materials. Numerous studies have extensively employed these databases using both behavioral and neuroimaging methods. However, some limitations of the existing databases have recently been reported, including limited numbers of stimuli in specific categories or poor picture quality of the visual stimuli. In the present article, we introduce the Nencki Affective Picture System (NAPS), which consists of 1,356 realistic, high-quality photographs that are divided into five categories (people, faces, animals, objects, and landscapes). Affective ratings were collected from 204 mostly European participants. The pictures were rated according to the valence, arousal, and approach–avoidance dimensions using computerized bipolar semantic slider scales. Normative ratings for the categories are presented for each dimension. Validation of the ratings was obtained by comparing them to ratings generated using the Self-Assessment Manikin and the International Affective Picture System. In addition, the physical properties of the photographs are reported, including luminance, contrast, and entropy. The new database, with accompanying ratings and image parameters, allows researchers to select a variety of visual stimulus materials specific to their experimental questions of interest.
