The connective or can be treated as an inclusive disjunction or else as an exclusive disjunction. Although researchers are aware of this distinction, few have examined the conditions under which each interpretation should be anticipated. Based on linguistic-pragmatic analyses, we assume that interpretations are initially inclusive before either (a) remaining so, or (b) becoming exclusive by way of an implicature ( but not both ). We point to a class of situations that ought to predispose disjunctions to inclusive interpretations and (...) to situations that encourage exclusive interpretations. A disjunction's ultimate interpretation is based on its potential informativeness, where the interpretation of the disjunctive utterance having the smallest number of true conditions is considered most informative. Our investigation leads to five experiments employing arbitrary materials. Among the problems expected to encourage inclusive interpretations are those that present disjunctions in the antecedents of conditionals and in question forms. The best candidates to produce implicatures are those disjunctions that underdetermine an expected conjunctive conclusion, although other disjunctive utterances that are more informative as exclusive are discussed and tested.

Lest the conjunction seduce readers into supposing that the two are of a piece, we point out that analyses made at the superset level concerning intelligence do not readily align with or outperform the scientific advances made via investigations of reasoning, which at best can be viewed as a subset of intelligent behaviour.

A conversational implicature is an inference that consists in attributing to a speaker an implicit meaning that goes beyond the explicit linguistic meaning of an utterance. This paper experimentallyinvestigates scalar implicature, a paradigmatic case of implicature in which a speaker's use of a term like Some indicates that the speaker had reasons not to use a more informative one from the samescale, e.g. All; thus, Some implicates Not all. Pragmatic theorists like Grice would predict that a pragmatic interpretation is determined (...) only after its explicit, logical meaning is incorporated (e.g. whereSome means at least one). The present work aims to developmentally unpack this prediction by showing how younger, albeit competent, reasoners initially treat a relatively weak term logically beforebecoming aware of its pragmatic potential. Three experiments are presented. Experiment 1 presents a modal reasoning scenario offering an exhaustive set of conclusions; critical among these isparticipants' evaluation of a statement expressing Might be x when the context indicates that the stronger Must be x is true. The conversationally-infelicitous Might be x can be understood logically(e.g. as compatible with Must) or pragmatically (as exclusive to must). Results from five-, seven-, and nine-year-olds as well as adults revealed that a) seven-year-olds are the youngest to demonstratemodal competence overall and that; b) seven- and nine-year-olds treat the infelicitous Might logically significantly more often than adults do. Experiment 2 showed how training with the modal taskcan suspend the implicatures for adults. Experiment 3 provides converging evidence of the developmental pragmatic effect with the French existential quantifier Certains (Some). Whilelinguistically-sophisticated children (eight- and ten-year-olds olds) typically treat Certains as compatible with Tous (All), adults are equivocal. These results, which are consistent with unanticipatedfindings in classic developmental papers, reveal a consistent ordering in which representations of weak scalar terms tend to be treated logically by young competent participants and morepragmatically by older ones. This work is also relevant to the treatment of scalar implicatures in the reasoning literature. (shrink)

In the wake of business scandals at Enron, Arthur Andersen, Global Crossing, Tyco—the list grows daily—there is an increasing sense among employees, executives, investors, and the public that the “anything goes” culture of the New Economy is over. Today, businesses must act responsibly, transparently, and with integrity. Using in-depth case studies and examples from over 50 companies that range from Starbucks to Citigroup, General Motors to General Electric, DuPont to Dell, Ira A. Jackson, former director of the Center for Business (...) and Government at Harvard’s Kennedy School, shows the quantifiable and enduring business advantage to “doing the right thing.” Companies that give back to their employees and society—focusing on values and purpose as well as profitability—often gain commpetitive advantage and improve their brand image, consumer loyalty, and employee satisfaction. Identifying seven principles of making values integral to business processes and practices, PROFITS WITH PRINCIPLES opens the door to a new kind of capitalism, providing a wealth of practical recommendations companies of all sizes can model their own efforts after.

Involuntary autobiographical memories are typically discussed in the context of negative memories such as trauma ‘flashbacks’. However, IAMs occur frequently in everyday life and are predominantly positive. In spite of this, surprisingly little is known about how such positive IAMs arise. The trauma film paradigm is often used to generate negative IAMs. Recently an equivalent positive film was developed inducing positive IAMs . The current study is the first to investigate which variables would best predict the frequency of positive IAMs. (...) Higher levels of positive mood change to the film were significantly associated with the number of positive IAMs recorded in the subsequent week. Results demonstrate the importance of positive emotional reaction at the time of an event for subsequent positive IAMs. (shrink)

The amount of social support literature in the field of interpersonal communication has increased steadily. In the last decade, however, no one has pushed for a conclusion as to what kind of phenomenon social support is. This article aims to describe the essence of social support. The essence is what must be present in all the phenomena that claim to be social support. The study uses phenomenological reduction and imag¬inative variation (1) on social support definitions and (2) on the empirical (...) material of support in men’s friendships. The synthesis of the two sets of material deduces the essence of social support both theoretically and empirically. According to the phenomenological reduction the essence of social support is the awareness of a real or potential void in a person’s life experience, and of otherness that intends to alter that experience to achieve wholeness. Supportive communication is the manifestation of the essence of social support in interpersonal relationships. (shrink)

Matching bias refers to the non-normative performance that occurs when elements mentioned in a rule do not correspond with those in a test item. One aim of the present work is to capture matching bias via reaction times as participants carry out truth-table evaluation tasks. Experiment 1 requires participants to verify conditional rules, and Experiment 2 to falsify them as the paradigm employs four types of conditional sentences that systematically rotate negatives in the antecedent and consequent; and presents predominantly cases (...) having true antecedents. These experiments reveal that mismatching is linked to higher rates of incorrect responses and slower evaluation times. A second aim is to investigate the way not is processed. We compare a narrow view of negations, which argues that negation only denies information, to a search for alternatives view, which says that negations function to prime appropriate alternatives. Findings from both experiments support a narrow reading view. (shrink)

Policy-makers must allocate scarce resources to support constituents’ health needs. This requires policy-makers to be able to evaluate health states and allocate resources according to some principle of allocation. The most prominent approach to evaluating health states is to appeal to the strength of people’s preferences to avoid occupying them, which we refer to as decision utility metrics. Another approach, experienced utility metrics, evaluates health states based on their hedonic quality. In this article, we argue that although decision utility metrics (...) face a number of significant problems, the appropriate response to these problems is not to replace them with experienced utility metrics. Rather, decision utility metrics should be employed in conjunction with experienced utility metrics. Specifically, respondents to decision utility surveys should be provided with the results of experienced utility metrics in an effort to make their decisions better informed and more robust to the deficiencies of decision utility metrics. Ultimately, this approach would improve quality-adjusted life year calculations and enhance the decision-making of policy-makers in allocating resources to support constituents’ health needs.

We present a set-theoretic model of the mental representation of classically quantified sentences (All P are Q, Some P are Q, Some P are not Q, and No P are Q). We take inclusion, exclusion, and their negations to be primitive concepts. We show that although these sentences are known to have a diagrammatic expres- sion (in the form of the Gergonne circles) that constitutes a semantic representation, these concepts can also be expressed syntactically in the form of algebraic formulas. (...) We hypothesized that the quantified sen- tences have an abstract underlying representation common to the formulas and their associated sets of dia- grams (models). We derived 9 predictions (3 semantic, 2 pragmatic, and 4 mixed) regarding people’s as- sessment of how well each of the 5 diagrams expresses the meaning of each of the quantified sentences. We report the results from 3 experiments using Gergonne’s (1817) circles or an adaptation of Leibniz (1903/ 1988) lines as external representations and show them to support the predictions. (shrink)

This paper explores the impact of group affiliation with respect to the on-line processing and appreciation of jokes, using facial electromyography activity and offline evaluations as dependent measures. Two experiments were conducted in which group affiliation varied between the participant and each of two independent speakers whose described political profiles were distinguished through one word: “Right” versus “Left.” Experiment 1 showed that jokes were more highly evaluated and that associated EMG activity was more intense when it was later determined that (...) the speaker was a member of the listener’s ingroup rather than outgroup. In an effort to determine whether these parochial effects can be isolated to ingroup favoritism as opposed to outgroup derogation, Experiment 2 paired a joke-teller described as politically active with one who was described as politically neutral. These more subtle comparisons suggest that the parochial effects observed in our joke understanding paradigm are mediated, at least in part, by the presence of an outgroup member. (shrink)

In the Nicomachean Ethics, Aristotle appears to use an elegant short argument to attack Plato's doctrine of the good, which argument equally appears to attack Aristotle's own doctrine of the good. I consider these two questions: First: Why does Aristotle reverse the judgment of Socrates/Plato on the issue: Which is better - things that are good in themselves, or things that are both good in themselves and good for their consequences? Second: Why does Aristotle attack Plato's doctrine that the Form (...) of the Good is the chief good, with an argument that appears to threaten his own view that eudaimonia is the chief good? I think the answers to these two questions are related. The elegant short argument in question I call "Aristotle's Fast Argument." After apologizing for criticizing views held by friends of his, Aristotle deploys the Fast Argument as a clincher to cap off his refutation of Plato's view that the Form of the Good is the chief good: "And one might ask the question, what in the world they mean by 'a thing itself', if in man himself and in a particular man the account of man is one and the same. For in so far as they are men, they will in no respect differ; and if this is so, neither will there be a difference in so far as they are good. But again it will not be good any the more for being eternal, since that which lasts long is no whiter than that which perishes in a day.". I explore this sketchily presented Fast Argument. I consider why Aristotle may think it is valid and why he does not seem to realize that, on readings that make it effective against Plato's view, his Fast Argument also seems to apply to his own view that eudaimonia is the chief good. This is what I will call "Aristotle's Dilemma." If the Fast Argument is interpreted too narrowly, its point about the whiteness of a white thing being independent of its duration will not apply to the goodness of the Form of the Good. If it is interpreted broadly enough to undermine the claim of the Form of the Good to be the chief good, it will equally undermine that claim for eudaimonia. Finally, I discuss some of the things Plato and Aristotle say about the chief good, and comparable things Immanuel Kant says about the good will. I draw some speculative conclusions that focus on the importance for Aristotle of the goodness of the chief good not being at risk. (shrink)

The model of cerebellar operation is mostly speculation. The same data can be interpreted in a very different way, making fewer assumptions. To wit, sets of Purkinje cells recognize a specific sensorimotor event and trigger a synchronous sensorimotor discharge.

The electrophysiological perspective presents an electrical field that is continuous throughout the body, with an intense focus of dynamically structured patterns at the cephalic end. That there is indeed an isomorphic mapping between the detailed holistic patterns in this field and in perception (at some level) seems certain. Temporal binding, however, may be a greater challenge than spatial binding.
