Weighted constraints in generative linguistics

Harmonic Grammar (HG) and Optimality Theory (OT) are closely related formal frameworks for the study of language. In both, the structure of a given language is determined by the relative strengths of a set of constraints. They differ in how these strengths are represented: as numerical weights (HG) or as ranks (OT). Weighted constraints have advantages for the construction of accounts of language learning and other cognitive processes, partly because they allow for the adaptation of connectionist and statistical models. HG has been little studied in generative linguistics, however, largely due to influential claims that weighted constraints make incorrect predictions about the typology of natural languages, predictions that are not shared by the more popular OT. This paper makes the case that HG is in fact a promising framework for typological research, and reviews and extends the existing arguments for weighted over ranked constraints.     

Power, propensity to negotiate, and moving first in competitive interactions

Five experiments investigated how the possession and experience of power affects the initiation of competitive interaction. In Experiments 1a and 1b, high-power individuals displayed a greater propensity to initiate a negotiation than did low-power individuals. Three additional experiments showed that power increased the likelihood of making the first move in a variety of competitive interactions. In Experiment 2, participants who were semantically primed with power were nearly 4 times as likely as participants in a control condition to choose to make the opening arguments in a debate competition scenario. In Experiment 3, negotiators with strong alternatives to a negotiation were more than 3 times as likely to spontaneously express an intention to make the first offer compared to participants who lacked any alternatives. Experiment 4 showed that high-power negotiators were more likely than low-power negotiators to actually make the first offer and that making the first offer produced a bargaining advantage.     

Correspondence analysis and association models constrained by a conditional independence graph

The manner in which the conditional independence graph of a multiway contingency table effects the fitting and interpretation of the Goodman association model (RC) and of correspondence analysis (CA) is considered.Estimation of the row and column scores is presented in this context by developing a unified framework that includes both models. Incorporation of the conditional independence constraints inherent in the graph may lead to equal or additive scores for the corresponding marginal tables, depending on the topology of the graph. An example of doubly additive scores in the analysis of a Burt subtable is given.Thanks are due to anonymous referees who substantially improved the original draft of this paper.

SLOTE ON RATIONAL DILEMMAS AND RATIONAL SUPEREROGATION

The so-called optimising conception of rationality includes (amongst other things) the following two claims: (i) that it is irrational to choose an option if you know there is a better one, and (ii) there are no situations in which an agent, through no practical fault of her own, cannot avoid acting irrationally. As part of his ongoing attempt to explain why we need to go beyond the optimising conception, Michael Slote discusses a number of examples in which it seems that (i) and (ii) are inconsistent. According to Slote, these situations seem to involve the existence of rational supererogation (a denial of (i)), or rational dilemmas (a denial of (ii)). The purpose of this paper is to examine Slote's arguments for these claims, and to propose an alternative solution to the problem he presents.     

Pornographic Materials and Commodity Theory

In a 2 × 2 × 2 × 2 (age restriction vs. no age restriction × sex of subject × pornography vs. nonpornography × pre-stimuli vs. post-stimuli test) factorial design, 40 males and 40 females received an experimental booklet containing either pornographic or nonpornographic pictures. Prior to seeing the pictures, half of the subjects of each sex were informed that the photographs came from magazines for adults only (21 years old and over), while the other half received no such information. Subjects were asked to rate the desirability of the pictures as well as their liking of and desire to read and purchase such materials prior to viewing and after viewing the pictures. The results indicated that (a) subjects who were not given age restriction information rated the yet unseen pictures more desirable than subjects who received age restriction information; (b) subjects who were given age restriction information rated the already seen pictures more desirable than subjects who received no age restriction information; (c) males rated pornographic pictures more favorably than did females; (d) subjects in the age restriction information condition expected the yet unseen pictures to be more pornographic than subjects in the no age restriction information condition; and (e) subjects, after seeing the stimuli, rated nonpornographic pictures more desirable than pornographic pictures. There was no support for the hypothesis that the effect of age restriction is an anticipatory phenomenon. The data in part supported and in part conflicted with Fromkin and Brock's (1973) proposition that imposing restrictions on the sale or purchase of pornographic materials will make these materials more attractive and desirable than they would be if there were no restrictions on them.
