Using Sound to Navigate the World: Echolocation by Bats and Blind Humans @ Nancy R. and Norton T. Dodge Performing Arts Center
4:40 PM to 5:40 PM
The Phi Beta Kappa Zeta Chapter of Maryland at St. Mary's College of Maryland is pleased to welcome Dr. Cynthia Moss, Professor of Psychological and Brain Sciences, with joint appointments in Neuroscience and Mechanical Engineering, at Johns Hopkins University as it's ninth PBK Visiting Scholar.
Humans tend to rely heavily on vision to navigate, but blind individuals must make use of other senses. Indeed, some blind humans produce tongue clicks and listen to echoes reflecting from objects in their surroundings, similar to echolocating bats and dolphins. In this lecture, Dr. Moss will present details on the sound features that are used for echolocation by animals and blind humans and the acoustic cues they use to localize objects in the environment. She will also discuss the contribution of spatial attention and memory to the execution of behavioral tasks without vision. By comparing echolocating animals and humans, we can identify biological specializations and general principles that operate to support spatial navigation.
