DeLong's research interests are in human and animal cognition and sensory perception. Past research has focused on cognitive representation, learning, and memory in two animal groups: cetaceans (dolphins and whales) and bats. Bats are active at night, where vision is only marginally useful, and cetaceans spend time underwater at depths where light does not penetrate. Instead of relying on vision, these animals use an active mode of sound perception called echolocation (biological sonar), during which they emit high-frequency sounds which bounce off objects and produce echoes. They use these echoes to navigate, find prey, and avoid obstacles. Her research involves investigating the content of the echo images and she has conducted research with dolphins, whales, bats and human subjects. Current and ongoing research program will encompass perception research with different animal species as well as human cognitive research.
DeLong teaches Introduction to Psychology, Cognitive Psychology, Psychology of Perception, Learning and Memory, Language and Problem Solving and Advanced Cognition.
