Just What Is Musical Tempo?
Justin London (Music, Carleton College)
When we listen to music its tempo is rarely, if ever, in doubt. Within just a few seconds, we know whether the music is fast, moderate, or slow. Yet the cues for these judgments are not simple or straightforward. This presentation will begin with a few illustrative examples, which we will then unpack in terms of their beat rate, loudness, event density, and spectral flux. The effect of familiarity with the music (and musical style) will then be considered. Moving beyond auditory cues, the effect of watching others moving while listening, as well as one's own movement while listening, will be added to the picture, showing that tempo perception has important cross-modal aspects. Finally, and perhaps as a way of untangling the Gordian knot of the auditory, visual, and kinesthetic cues for tempo, an energistic account of tempo is given, suggesting that "tempo" is not so much a measure of musical speed, but rather an index of the energy required to produce and/or move with the music.

Perspective-taking and Dishonest Communication in Primates and Other Animals
Frans BM de Waal, Living Links, Yerkes National Primate Research Center, Emory University
The study of Theory-of-Mind (ToM) began with ape research by Emil Menzel and later David Premack after which it expanded in developmental psychology, which made it a key measure of social intelligence. Recently, ToM research returned with a vengeance to the apes when a False Belief task was finally conducted. The apes seemed to pass, which adds evidence that apes and a few other nonhuman animals can take the perspective of others. One of the expressions of this capacity is tactical deception, which is clearly more developed in apes than most other species, although there is also evidence for corvids. There is plenty of functional deception in animals (e.g. mimicry), but tactical deception is more flexible and based on learning and anticipation of the reactions of others. It may require enhanced perspective-taking and self-other distinction. I will review the evidence for this capacity in the primates based on both experimental studies and anecdotal information.
Lying, American Style
Bradd Shore, Department of Anthropology, Emory University
Even for the most ardent empiricist, there can be no objective definition of lying. Like many of our familiar ideas, lying can only make sense as “a cultural model” rather than as a simple objective phenomenon. In this talk, I will try to illuminate some of the presuppositions that underwrite the American cultural model, and to suggest some of the ways in which this model has been politically deployed and manipulated in recent decades.
Little liars: How children learn to tell lies?
Kang Lee, Professor & Canada Research Chair Tier 1, University of Toronto
In this talk, I will use scientific evidence from my lab and others over the last two decades to show that lying begins early in life and discuss what factors contribute or do not contribute to the development of lying, why children lie, and whether we adults can easily detect children’s lies. Furthermore, I will discuss recent developments in technology that may help us detect children’s lies and such technology’s applications in lie-detection and beyond.
Face Value: The Irresistible (and misleading) Influence of First Impressions
Alexander Todorov, Department of Psychology, Princeton University
Physiognomy – the pseudoscience of reading character from faces – has long been discredited, but we are all naïve physiognomists. People form instantaneous impressions from faces, agree on these impressions, and act on these impressions. In the last 10 years, we have introduced data-driven computational methods that allow us to visualize the configurations of face features leading to specific impressions such as trustworthiness. That is, we are able to visualize appearance stereotypes. But are these stereotypes accurate? In the last decade, there has been a resurgence of studies claiming that the stereotypes are indeed accurate. But a closer look at the modern studies shows that the claims of the new physiognomy are almost as exaggerated as those of the old physiognomy. First, different images of the same person can lead to completely different impressions. Second, often our decisions are more accurate if we completely ignore face information and rely on common knowledge. So why do we form first impressions? In our quest to know others and in the absence of good information, we are forced to rely on appearance information. This information could be useful as a guide to the intentions and actions of the person in the immediate here and now, but it is misleading as a guide to the person’s character.
What Happened to The News? - Technology, Politics and the Vanishing Truth
Jonathan Mann CNN International anchor
Many Americans believe that the news media intentionally lie to them. President Donald Trump is the best-known detractor of "fake news," though he himself has been accused of lying more than any other public figure in recent memory. Former CNN anchor Jonathan Mann will address the overlapping changes to technology, politics and business that have crippled our national conversation with deception and distrust.
Onions and Identities: Theater and the True Self
Tim McDonough, Theater Studies, Emory University. Resident Artist, Theater Emory
The conflict between truth and deceit, reality and appearance, being and seeming is a theme to which theater is perfectly suited, because theater is deception in service of truth. Drama is densely populated by duplicitous schemers, by power figures whose lies maintain the sociopolitical status quo, and by characters in search of themselves, who mirror to us our confusions and self-deceptions about self. Theater provides a template for understanding identity and insight into several existentially and socially necessary forms of deceit. Excerpts from Hamlet, King Lear, Peer Gynt, Angels in America, and several other plays.
The Science of Magic and the Art of Deception
Alex Stone, Professional magician, writer and entertainer, New York City
“Magic takes place not in the hands of the magician but in the mind of the spectator.”
Magic is dramatized deception, lying as performance art, cons as theatre. Magicians trick our brains into seeing what isn’t real, and for whatever reason our brains let them get away with it. Turns out, you can learn a lot about how the mind works—and why it sometimes doesn’t—by looking at how magicians distort our perception. Through a mix of psychology, storytelling, and sleight-of-hand, Stone explores the cognitive underpinnings of misdirection, illusion, scams, and secrecy, pulling back the curtain on the many curious and powerful ways our brains deceive us—not just when we’re watching a magician stage his swindles, but throughout our everyday lives.
