The most interesting topic learned in this class was echolocation which is locating objects by reflecting sound. while reading the perception book I learned that blind people use echolocation to know where they are going. In specific, blind mountain bikers were able to know the trail they were rideing just based on echolocation. I further researched this topic and found that researchers did a study on blind and sighted people that never used echolocation before. While under a functional magnetic resonance imaging scanner, researchers played sounds in different parts of the room and found that when playing the sounds showed activity in non-sighted people's primary visual cortex which is similar to sighted people looking at visual stimuli (Servick, 2019)
