His perceptual research aims to elucidate neural mechanisms of consciousness and perception using machine learning. Vaughn has presented his findings on empathy and neuroplasticity in a TEDx talk [2] as well as at the Society for Neuroscience [3] [4] and DARPA Network Narratives. [5]

Science

Research

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.

TEDx

Vaughn gave a TEDx talk at UCLA on neuroplasticity, entitled "Neurohacking: Rewiring Your Brain". [2] [13]

Media

Vaughn has made TV appearances on Entertainment Tonight , [14] The Today Show , [15] Nova ScienceNow , [16] ShapingHOU, [17] Great Day Houston, [18] and Local KPRC. [19] Vaughn has been featured in Time , [20] 002houston, [21] Cosmopolitan , [22] Houston Magazine, [23] First Class Magazine, [24] Houston Chronicle , [25] Daily Bruin , [26] and Culture Map. [27]

Music career

From 2012 to 2015 Vaughn was also a DJ and producer. His first album, entitled The Don Vaughn Experiment, [28] [29] featured former 98 Degrees singer Nick Lachey, reached #28 on the iTunes Dance charts.

Victoria Vesna, Mark Cohen, Vaughn, and others in the art and science community at UCLA [30] presented a performance entitled "brainstorming" at Sonos Studios [31] in Los Angeles. The exhibit explored the effect of music on feelings of connectedness, and how brain activity changed as a result.

<span class="mw-page-title-main">Neurolinguistics</span> Neuroscience and linguistics-related studies

Neurolinguistics is the study of neural mechanisms in the human brain that controls the comprehension, production, and acquisition of language. As an interdisciplinary field, neurolinguistics draws methods and theories from fields such as neuroscience, linguistics, cognitive science, communication disorders and neuropsychology. Researchers are drawn to the field from a variety of backgrounds, bringing along a variety of experimental techniques as well as widely varying theoretical perspectives. Much work in neurolinguistics is informed by models in psycholinguistics and theoretical linguistics, and is focused on investigating how the brain can implement the processes that theoretical and psycholinguistics propose are necessary in producing and comprehending language. Neurolinguists study the physiological mechanisms by which the brain processes information related to language, and evaluate linguistic and psycholinguistic theories, using aphasiology, brain imaging, electrophysiology, and computer modeling.

Computational neuroscience is a branch of neuroscience which employs mathematical models, computer simulations, theoretical analysis and abstractions of the brain to understand the principles that govern the development, structure, physiology and cognitive abilities of the nervous system.

A mental image is an experience that, on most occasions, significantly resembles the experience of 'perceiving' some object, event, or scene, but occurs when the relevant object, event, or scene is not actually present to the senses. There are sometimes episodes, particularly on falling asleep and waking up, when the mental imagery may be dynamic, phantasmagoric and involuntary in character, repeatedly presenting identifiable objects or actions, spilling over from waking events, or defying perception, presenting a kaleidoscopic field, in which no distinct object can be discerned. Mental imagery can sometimes produce the same effects as would be produced by the behavior or experience imagined.

<span class="mw-page-title-main">Neuroesthetics</span> Sub-discipline of empirical aesthetics

Neuroesthetics is a relatively recent sub-discipline of applied aesthetics. Empirical aesthetics takes a scientific approach to the study of aesthetic experience of art, music, or any object that can give rise to aesthetic judgments. Neuroesthetics is a term coined by Semir Zeki in 1999 and received its formal definition in 2002 as the scientific study of the neural bases for the contemplation and creation of a work of art. Neuroesthetics uses neuroscience to explain and understand the aesthetic experiences at the neurological level. The topic attracts scholars from many disciplines including neuroscientists, art historians, artists, art therapists and psychologists.

Cognitive development is a field of study in neuroscience and psychology focusing on a child's development in terms of information processing, conceptual resources, perceptual skill, language learning, and other aspects of the developed adult brain and cognitive psychology. Qualitative differences between how a child processes their waking experience and how an adult processes their waking experience are acknowledged. Cognitive development is defined as the emergence of the ability to consciously cognize, understand, and articulate their understanding in adult terms. Cognitive development is how a person perceives, thinks, and gains understanding of their world through the relations of genetic and learning factors. There are four stages to cognitive information development. They are, reasoning, intelligence, language, and memory. These stages start when the baby is about 18 months old, they play with toys, listen to their parents speak, they watch tv, anything that catches their attention helps build their cognitive development.

Neuroplasticity, also known as neural plasticity, or brain plasticity, is the ability of neural networks in the brain to change through growth and reorganization. It is when the brain is rewired to function in some way that differs from how it previously functioned. These changes range from individual neuron pathways making new connections, to systematic adjustments like cortical remapping. Examples of neuroplasticity include circuit and network changes that result from learning a new ability, environmental influences, practice, and psychological stress.

Neuroconstructivism is a theory that states that phylogenetic developmental processes such as gene–gene interaction, gene–environment interaction and, crucially, ontogeny all play a vital role in how the brain progressively sculpts itself and how it gradually becomes specialized over developmental time.

<span class="mw-page-title-main">Reward system</span> Group of neural structures responsible for motivation and desire

The reward system is a group of neural structures responsible for incentive salience, associative learning, and positively-valenced emotions, particularly ones involving pleasure as a core component. Reward is the attractive and motivational property of a stimulus that induces appetitive behavior, also known as approach behavior, and consummatory behavior. A rewarding stimulus has been described as "any stimulus, object, event, activity, or situation that has the potential to make us approach and consume it is by definition a reward". In operant conditioning, rewarding stimuli function as positive reinforcers; however, the converse statement also holds true: positive reinforcers are rewarding.

<span class="mw-page-title-main">Is Google Making Us Stupid?</span> Magazine article by technology writer Nicholas G. Carr

Is Google Making Us Stupid? What the Internet Is Doing to Our Brains! is a magazine article by technology writer Nicholas G. Carr, and is highly critical of the Internet's effect on cognition. It was published in the July/August 2008 edition of The Atlantic magazine as a six-page cover story. Carr's main argument is that the Internet might have detrimental effects on cognition that diminish the capacity for concentration and contemplation. Despite the title, the article is not specifically targeted at Google, but more at the cognitive impact of the Internet and World Wide Web. Carr expanded his argument in The Shallows: What the Internet Is Doing to Our Brains, a book published by W. W. Norton in June 2010.

<span class="mw-page-title-main">Laura-Ann Petitto</span> American psychologist and neuroscientist (born c. 1954)

Laura-Ann Petitto is a cognitive neuroscientist and a developmental cognitive neuroscientist known for her research and scientific discoveries involving the language capacity of chimpanzees, the biological bases of language in humans, especially early language acquisition, early reading, and bilingualism, bilingual reading, and the bilingual brain. Significant scientific discoveries include the existence of linguistic babbling on the hands of deaf babies and the equivalent neural processing of signed and spoken languages in the human brain. She is recognized for her contributions to the creation of the new scientific discipline, called educational neuroscience. Petitto chaired a new undergraduate department at Dartmouth College, called "Educational Neuroscience and Human Development" (2002-2007), and was a Co-Principal Investigator in the National Science Foundation and Dartmouth's Science of Learning Center, called the "Center for Cognitive and Educational Neuroscience" (2004-2007). At Gallaudet University (2011–present), Petitto led a team in the creation of the first PhD in Educational Neuroscience program in the United States. Petitto is the Co-Principal Investigator as well as Science Director of the National Science Foundation and Gallaudet University’s Science of Learning Center, called the "Visual Language and Visual Learning Center (VL2)". Petitto is also founder and Scientific Director of the Brain and Language Laboratory for Neuroimaging (“BL2”) at Gallaudet University.

Activity-dependent plasticity is a form of functional and structural neuroplasticity that arises from the use of cognitive functions and personal experience; hence, it is the biological basis for learning and the formation of new memories. Activity-dependent plasticity is a form of neuroplasticity that arises from intrinsic or endogenous activity, as opposed to forms of neuroplasticity that arise from extrinsic or exogenous factors, such as electrical brain stimulation- or drug-induced neuroplasticity. The brain's ability to remodel itself forms the basis of the brain's capacity to retain memories, improve motor function, and enhance comprehension and speech amongst other things. It is this trait to retain and form memories that is associated with neural plasticity and therefore many of the functions individuals perform on a daily basis. This plasticity occurs as a result of changes in gene expression which are triggered by signaling cascades that are activated by various signaling molecules during increased neuronal activity.

Educational neuroscience is an emerging scientific field that brings together researchers in cognitive neuroscience, developmental cognitive neuroscience, educational psychology, educational technology, education theory and other related disciplines to explore the interactions between biological processes and education. Researchers in educational neuroscience investigate the neural mechanisms of reading, numerical cognition, attention and their attendant difficulties including dyslexia, dyscalculia and ADHD as they relate to education. Researchers in this area may link basic findings in cognitive neuroscience with educational technology to help in curriculum implementation for mathematics education and reading education. The aim of educational neuroscience is to generate basic and applied research that will provide a new transdisciplinary account of learning and teaching, which is capable of informing education. A major goal of educational neuroscience is to bridge the gap between the two fields through a direct dialogue between researchers and educators, avoiding the "middlemen of the brain-based learning industry". These middlemen have a vested commercial interest in the selling of "neuromyths" and their supposed remedies.
