Questions,Presuppositions and Fallacies

In this paper I focus on the fallacy known as Complex Question or Many Questions. After a brief introduction, in Sect. 2 I highlight its pragmatic dimension, and in Sect. 3 its dialectical dimension. In Sect. 4 I present two accounts of this fallacy developed in argumentation theory, Douglas Walton’s and the Pragma-Dialectics’, which have resources to capture both its pragmatic and its dialectical nature. However, these accounts are unsatisfactory for various reasons. In Sect. 5 I focus on the pragmatic dimension of the fallacy and I suggest amendments to the accounts mentioned drawing on the study of the phenomenon of presupposition in theoretical pragmatics. I argue that the central notion in the definition of the fallacy is that of an informative presupposition. In Sect. 6 I focus on the dialectical dimension of the fallacy. This dimension needs to be explicitly acknowledged in the definition of the fallacy in order to distinguish it from a different, non-dialectical, fallacious argumentative move involving presuppositions.

     

Emotions induced by operatic music: psychophysiological effects of music, plot, and acting: a scientist's tribute to Maria Callas

Operatic music involves both singing and acting (as well as rich audiovisual background arising from the orchestra and elaborate scenery and costumes) that multiply the mechanisms by which emotions are induced in listeners. The present study investigated the effects of music, plot, and acting performance on emotions induced by opera. There were three experimental conditions: (1) participants listened to a musically complex and dramatically coherent excerpt from Tosca; (2) they read a summary of the plot and listened to the same musical excerpt again; and (3) they re-listened to music while they watched the subtitled film of this acting performance. In addition, a control condition was included, in which an independent sample of participants succesively listened three times to the same musical excerpt. We measured subjective changes using both dimensional, and specific music-induced emotion questionnaires. Cardiovascular, electrodermal, and respiratory responses were also recorded, and the participants kept track of their musical chills. Music listening alone elicited positive emotion and autonomic arousal, seen in faster heart rate, but slower respiration rate and reduced skin conductance. Knowing the (sad) plot while listening to the music a second time reduced positive emotions (peacefulness, joyful activation), and increased negative ones (sadness), while high autonomic arousal was maintained. Watching the acting performance increased emotional arousal and changed its valence again (from less positive/sad to transcendent), in the context of continued high autonomic arousal. The repeated exposure to music did not by itself induce this pattern of modifications. These results indicate that the multiple musical and dramatic means involved in operatic performance specifically contribute to the genesis of music-induced emotions and their physiological correlates.     

Generic statements require little evidence for acceptance but have powerful implications

Generic statements (e.g., "Birds lay eggs") express generalizations about categories. In this paper, we hypothesized that there is a paradoxical asymmetry at the core of generic meaning, such that these sentences have extremely strong implications but require little evidence to be judged true. Four experiments confirmed the hypothesized asymmetry: Participants interpreted novel generics such as "Lorches have purple feathers" as referring to nearly all lorches, but they judged the same novel generics to be true given a wide range of prevalence levels (e.g., even when only 10% or 30% of lorches had purple feathers). A second hypothesis, also confirmed by the results, was that novel generic sentences about dangerous or distinctive properties would be more acceptable than generic sentences that were similar but did not have these connotations. In addition to clarifying important aspects of generics' meaning, these findings are applicable to a range of real-world processes such as stereotyping and political discourse.     

Tailoring Gratitude Interventions. How and for Whom Do They Work? The Potential Mediating Role of Reward Processing and the Moderating Role of Childhood Adversity and Trait Gratitude

Outcomes of gratitude interventions are encouraging, but inconsistent across studies. In addition, both mechanisms of change and effect modifiers for these interventions are largely unknown. Recent data point toward potential candidates and suggest reward processing may be a promising mechanism underlying these interventions, while childhood adversity (CA) and trait gratitude may impact on them. However, existing research aimed at investigating these hypotheses is scarce. Building on these, we examined the effectiveness of a gratitude intervention for decreasing depressive symptoms and negative affect and increasing positive affect. We also investigated changes in reward processing following intervention and explored differences in adherence and drop-out between groups. Finally, we investigated the moderating role of CA and trait gratitude.

Participants (N=237, ages between 18–56) were randomly allocated to a gratitude or active control condition (14 days). Following intervention, findings indicated a significant decrease in depressive symptoms and negative affect in both conditions. While positive affect remained stable, a significant time effect emerged for reward processing. CA severity, but not multiplicity, moderated the effectiveness of the intervention, adherence and drop-out. Trait gratitude moderated the effectiveness of the gratitude intervention only on depressive symptoms.

Gratitude interventions may not be the best fit for everyone. Thus, we recommend tailoring interventions, especially in individuals reporting a history of severe CA.

     

On The Virtue of Judging Others

An other‐directed moral judgement is contrasted with a moral evaluation of one's own behaviour; it is argued that having a capacity to make self‐directed moral judgements is at the core of being within morality, while a lack of disposition on the part of a mature individual to judge others is indicative of the corresponding lack with regard to the self‐directed evaluations. Our readiness to evaluate the behaviour of others measures the level of our commitment to a system of morality. Consistent nonjudgementalism subverts the interpersonal nature of moral values and points to a deeper issue – an unwillingness of a nonjudgementalist to apply moral categories to her own choices.     

Descriptions and Tests for Polysemy

Viebahn (Pac Philos Q 99:749–762, 2018. https://doi.org/10.1111/papq.1222) has recently argued that several tests for ambiguity, such as the conjunction-reduction test, are not reliable as tests for polysemy, but only as tests for homonymy. I look at the more fine-grained distinction between regular and irregular polysemy and I argue for a more nuanced conclusion: the tests under discussion provide systematic evidence for homonymy and irregular polysemy but need to be used with more care to test for regular polysemy. I put this conclusion at work in the context of the debate over the alleged referential-attributive ambiguity of the definite article. In reply to various criticisms, defenders of the ambiguity view argue that this is a case of polysemy. But opponents object that the dual use of the definite article fails tests for ambiguity. The debate seems to have come to stalemate, unless the relevance of the tests is determined for cases of alleged polysemy. I conclude that the balance of considerations incline towards rejecting the ambiguity thesis.
