Comic Impossibilities

Argues for the controversial and initially counterintuitive thesis that theatrical magic (that is, the performance of conjuring tricks) is a form of standup comedy

Sonic Pictures

Winning essay of the American Society for Aesthetics' inaugural Peter Kivy Prize. Extends Kivy's notion of sonic picturing through engagement with recent work in philosophy of perception. Argues that sonic pictures are more widespread and more aesthetically and artistically important than even Kivy envisioned. Topics discussed include: the nature of sonic pictures; the nature of sounds; what we can (and more importantly, cannot) conclude from musical listening; sonic pictures in film; beatboxing as an art of sonic picturing; and cover songs as sonic pictures. To be published in the Journal of Aesthetics and Art Criticism

Resilient Understanding: The Value of Seeing for Oneself

The primary aim of this paper is to argue that the value of understanding derives in part from a kind of subjective stability of belief that we call epistemic resilience. We think that this feature of understanding has been overlooked by recent work, and we think it’s especially important to the value of understanding for social cognitive agents such as us. We approach the concept of epistemic resilience via the idea of the experience of epistemic ownership and argue that the former concept has Platonic pedigree. Contrary to longstanding exegetical tradition, we think that Plato solves the “Meno problem” with an appeal to the epistemic resilience characteristic of understanding, not the well-groundedness characteristic of canonical cases of propositional knowledge. Finally, we apply our discussion to the case of science outreach and the challenge of global warming skepticism and conclude with directions for future research

Understanding “Understanding” in Public Understanding of Science

This study examines the conflation of terms such as “knowledge” and “understanding” in peer-reviewed literature, and tests the hypothesis that little current research clearly distinguishes between importantly distinct epistemic states. Two sets of data are presented from papers published in the journal Public Understanding of Science. In the first set, the digital text analysis tool, Voyant, is used to analyze all papers published in 2014 for the use of epistemic success terms. In the second set of data, all papers published in Public Understanding of Science from 2010–2015 are systematically analyzed to identify instances in which epistemic states are empirically measured. The results indicate that epistemic success terms are inconsistently defined, and that measurement of understanding, in particular, is rarely achieved in public understanding of science studies. We suggest that more diligent attention to measuring understanding, as opposed to mere knowledge, will increase efficacy of scientific outreach and communication efforts

Using accelerometry to classify physical activity intensity in older adults:What is the optimal wear-site?

This study aimed to determine the optimal accelerometer wear-site specific cut-points for discrimination of the sedentary time, light physical activity and moderate-to-vigorous physical activity (MVPA) in older adults. Twenty-three adults (14 females) aged 55-77 years wore a GENEActiv accelerometer on their non-dominant wrist, dominant wrist, waist and dominant ankle whilst undertaking eight, five-minute bouts of activity: lay supine, seated reading, slow walking, medium walking, fast walking, folding laundry, sweeping and stationary cycling. VO2 was assessed concurrently using indirect calorimetry. Receiver-operating-characteristic (ROC) analyses were used to derive wear-site specific cut-points for classifying intensity. Indirect calorimetry indicated that being lay supine and seated reading were classified as sedentary (3 METs). Areas under ROC curves indicated that the classification of sedentary activity was good for the non-dominant wrist and excellent for all other wear sites. Classification of MVPA was excellent for the waist and ankle, good for the waist and poor for the dominant and non-dominant wrists. Overall, the ankle location performed better than in other locations. Ankle-worn accelerometry appears to provide the most suitable wear-site to discriminate between sedentary time and MVPA in older adults

What We Hear

A longstanding philosophical tradition holds that the primary objects of hearing are sounds rather than sound sources. In this case, we hear sound sources by—or in virtue of—hearing their sounds. This paper argues that, on the contrary, we have good reason to believe that the primary objects of hearing are sound sources, and that the relationship between a sound and its source is much like the relationship between a color and its bearer. Just as we see objects in seeing their colors, so we hear sound sources in hearing their sounds

Sounds Fully Simplified

In ‘The Ockhamization of the event sources of sound’ (2013), Roberto Casati, Elvira Di Bona, and Jérôme Dokic argue that ‘ockhamizing’ Casey O’Callaghan’s account of sounds as proper parts of their event sources yields their preferred view: that sounds are identical with their event sources. This article argues that the considerations Casati et al. marshal in favor of their view are actually stronger considerations in favor of a quite different view: a variant on the Lockean conception of sounds as ‘sensible qualities’ that treats sounds as audible properties of their event sources
