A recent Science News article, “Human echolocation works step by step,” features research by Smith-Kettlewell scientists Santani Teng and Haydée García-Lázaro. Their study, “Neural and Behavioral Correlates of Evidence Accumulation in Human Click-Based Echolocation,” shows how expert echolocators build spatial information over multiple click-echo pairs.

Human Echolocation
What is echolocation? Sometimes, the surrounding world is too dark and silent for typical vision and hearing. This is true in deep caves, for example, or in murky water where little light penetrates. Animals living in these environments often have the ability to echolocate: They make sounds and listen for their reflections. Like turning on a flashlight in a dark room, echolocation is a way to illuminate objects and spaces actively using sound.
