The Blind Individuals Who See By Sound

Using a technique similar to what bats and dolphins use, human echo-locators navigate using audio cues given off by reflective surfaces in the environment. Few people know that this same technique can work for human beings. But as a matter of fact, echolocation comes quite naturally to people like Daniel Kish, who were deprived of visual information from a young age. Read an excerpt on echolocation from The Superhuman Mind in this month's issue of Discover Magazine.

The First Known Female Acquired Savant

My PI and co-author of The Superhuman Mind: Free the Genius is Your Brain recently sat down with ABC's Nightline to explain the fascinating case of Leigh Erceg, a colorado rancher who acquired synesthesia after sustaining severe spinal and brain injuries. Not only did she regain her ability to walk, she's become a prolific artist and poet.

Is the relativity of Simultaneity a Temporal Illusion?

In this recent paper in the philosophical journal Analysis, Berit Brogaard and I defend Tensism against a popular objection. Tensism holds that the present moment has a special status that sets it apart from the past and the future, independently of perceivers. One of the main objections to this view has been Einstein’s argument from special relativity, which aims at showing that absolute simultaneity is a myth. We argue that the moving observer in a causal variant of Einstein’s original thought experiment is subject to a temporal illusion. Owing to the analogy of the cases, this casts doubt on the conjectures that there is no privileged frame of reference and that special relativity poses a problem for tensism.

Hearing colours: On a remarkable phenomenon with philosophical implications

In this recent article Berit Brogaard and I wrote for The Philosophers’ Magazine, we discuss the philosophical implications of synesthesia, a neurological condition where the senses are mixed. For example, some synesthetes attribute particular colors or personalities to letters and numbers to tastes to certain words. It turns out that this fascinating endowment might inform our understanding of many cognitive areas including memory and human intelligence.

 Synesthesia is a complex condition in which the senses are mixed. In this episode of St. Louis on the Air, I speak with Don Marsh about how synesthesia research might provide insight as to how the brain works.
