Working in David Eagleman's laboratory,[6] Vaughn helped discover that brains create perception by integrating peri-dictively, that is, information both before and after an event contribute to our perception of it.[7] Eagleman and Vaughn also discovered the "glimpse effect", in which briefly glimpsed photographs of people were judged to be more attractive than the same photographs viewed for a long duration.[8]
As a QCBio Collaboratory Fellow, he teaches a seminar on modern statistical methods (permutations, machine learning, bootstrapping) to UCLA faculty, postdoctoral fellows, and students.[9] He also taught machine learning at the UCLA NITP Summer Course.[10] He earned his PhD in neuroscience at UCLA with his thesis entitled "Using Machine-Learning to Diagnose Perception, Feeling, and Action: A Study of Neuroimaging, Psychometric, and Insurance Claims Data".[11]
Recently, Vaughn and Ariana Anderson received a grant from UCLA's CTSI Research to develop ChatterBaby, an app that facilitates communication between hearing-impaired parents and their hearing-abled babies. The app facilitates communication between parent and child by translating sound into colored waveforms in real-time, allowing parents to develop a visual intuition of what their and their babies's speech sounds like. This "sensory substitution" will allow parents to not only recognize patterns when their child speaks, but also tailor their own speech patterns to what best allows them to communicate with their child. ChatterBaby is featured in Vaughn's TEDx talk, but is undergoing more development before public release.[2]
Vaughn and Eagleman created an app, eyeFi [12] which acts as a reverse visualizer, turning video information into sound. eyeFi is an entertainment of a deeper concept the two were exploring on using sensory substitution to overcome visual impairments by translating vision into audio for the blind.
