Humans throughout history have described a peculiar state between sleep and wakefulness characterized by paralysis, conscious awareness of one’s surroundings, and terrifying hallucinations. We currently term this phenomenon "sleep paralysis," but it has gone by many other names depending upon time, place, and culture (e.g., kanashibari, the "old hag", nocturnal alien abductions, the Mara).  Although it is a very scary experience not well-known to the lay public, it is actually a fairly well-understood sleep disorder.  After first discussing the history of sleep paralysis in myth/folklore and its many connections to paranormal beliefs, the current medical and psychological literatures will be summarized. Finally, the many interesting attempts to "treat" these episodes across the ages will be described.

Brian A. Sharpless, Ph.D. is an Associate Professor of Clinical Psychology at the American School of Professional Psychology (ASPP) at Argosy University - Northern Virginia. After completing his graduate work at Pennsylvania State University, he completed his post-doctoral training at the University of Pennsylvania.  Dr. Sharpless has broad research interests in psychopathology, psychodynamic psychotherapy, and the history/philosophy of clinical psychology. He (along with Karl Doghrmaji, MD) is author of Sleep Paralysis: Historical, Psychological, and Medical Perspectives and editor of Unusual and Rare Psychological Disorders: A Handbook for Clinical Practice and Research.  Both volumes are currently available through Oxford University Press.

A Rational Approach to Oral Tradition and Stonehenge

Writer, researcher, science educator and
Foundation member of the Australian Skeptics

Indigenous cultures are usually represented as living in a fog of superstition. A rational glimpse says that they simply wouldn’t have survived if that were the case. We need to be skeptical of simplistic explanations of indigenous cultures that talk only about child-like stories and exotic religious rituals. They needed field guides to all the plants, all the animals, geology and astronomy. They needed navigational charts to travel great distances for trade, and genealogies to ensure they didn’t interbreed. They needed a legal system and ethical rules … but they had no writing. How did they memorize so much stuff?

This talk will explain the tricks of their memory trade and how we can use these methods in contemporary society. Mobile hunter-gatherers, such as Australian Indigenous cultures, embedded a highly pragmatic knowledge system in the landscape. What happens in the transition to farming? That question explains the detailed archaeological record of a vast range of prehistoric monuments including Stonehenge, the Nazca Lines and the statues of Easter Island.

Dr. Lynne Kelly is an Australian writer, researcher and science educator, as well as being a foundation member of the Australian Skeptics. Her academic work focuses on the way indigenous cultures memorize vast amounts of rational information through the mnemonic devices used by ancient and modern oral cultures from around the world. In applying that research to archaeology, she has proposed a new theory for the purpose of Stonehenge and ancient monuments the world over.  Her new book, The Memory Code: The Secrets of Stonehenge, Easter Island and Other Ancient Monuments (Pegasus Books, 2017), has already gone into reprint in Australia.

March 11 - Earth In Human Hands: Shaping Our Planet’s Future

Presented by David Grinspoon, Ph.D.
Senior scientist at the Planetary Science Institute

David Grinspoon will be talking about his new book Earth In Human Hands: Shaping Our Planet’s Future.   Among the topics to be discussed is the merits and demerits of “activating” the Search for Extra-Terrestrial Intelligence (SETI) by transitioning from passive listening to deliberate sending of messages to targeted star systems.  This has become something of a hot topic again with the publication of the end-note in a recent Communications of the ACM by Seth Shostak, wherein SETI’s senior astronomer takes an uncharacteristically pessimistic view of the possible consequences of reaching out to our interstellar neighbors. Can science fiction serve as a Gedankenexperiment for possible outcomes in advance of the actuality? 

Copies of Dr. Grinspoon’s book will be available.

David Grinspoon is an astrobiologist, award-winning science communicator, and prize-winning author. He is a senior scientist at the Planetary Science Institute and adjunct professor of astrophysical and planetary science at the University of Colorado. His research focuses on climate evolution on Earth-like planets and potential conditions for life elsewhere in the universe. In 2013 he was appointed as the inaugural chair of astrobiology at the U.S. Library of Congress where he studied the human impact on Earth systems and organized a public symposium on the Longevity of Human Civilization.  Dr. Grinspoon has been recipient of the Carl Sagan Medal for Public Communication of Planetary Science by the American Astronomical Society and has been honored with the title “Alpha Geek” by “Wired Magazine.”
