Talker Variability at ASA 2018 in Minneapolis

May 14th, 2018

Scientists from the CNRLab presented two new research studies on perception and cognition of talker variability at the May 2018 of the Acoustical Society of America in Minneapolis, including the results from a Sargent Senior Thesis for Distinction completed by lab alumna Kristina Furbeck.

CNRLab scientists are using the new Siemens 3T Prisma scanner at the BU Cognitive Neuroimaging Center to study how the brain consistently recognizes speech in different contexts. Read more about our experiences with the new imaging center in this article from BU Today.

Dyslexia and the brain: A problem with rapid neural adaptation

December 21st, 2016

dyslexia-adaptation-figure_web_small

Our new findings, published today in Neuron, reveal that the brains of children and adults with dyslexia show less rapid neural adaptation than the brains of typical readers. Rapid neural adaptation is a kind of learning that the brain does in just a few seconds to make perception more efficient. A dysfunction of rapid neural adaptation may make it difficult for individuals with dyslexia to coordinate the demanding neural plasticity involved in learning to read.

Exploring how the brain understands sentences

October 11th, 2016

tlscottA new paper in PNAS, coauthored by Terri Scott, CNRLab doctoral student, and researchers at Harvard (Ev Fedorenko) and MIT (Nancy Kanwisher), explores how the brain extracts meaning as sentences unfold. This work “opens up new avenues for investigating the sequence of neural events that underlie construction of linguistic meaning.”

Future of Language Science

October 3rd, 2016

Dr. Perrachione presented work from the CNRLab at the Future of Language Science symposium at Northwestern University. The symposium included alumni presentations in celebration of the Department of Linguistics‘ 50th anniversary.

In his presentation, Dr. Perrachione reported new work conducted at Boston University studying how noninvasive brain stimulation can facilitate foreign language learning, and two ongoing projects with collaborators from MIT investigating how the brain changes as a result of foreign language learning.

Congratulations, Ja Young!

CNRLab undergraduates featured at UROP symposium

October 16th, 2015

Elly Hu (CAS ’16) presents her poster on “Stimulus variability in rapid auditory categorization.” Elly used behavioral methods and noninvasive neurostimulation to investigate the factors that affect listeners’ ability to adapt to phonetic consistency in speech.7D2_3747_600x400

Tyrone Hou (CAS ’18) presented his e-poster on “Computerized biofeedback for lexical tone learning.” Tyrone developed a computer program that automatically compares a speaker’s lexical tone productions to canonical Mandarin lexical tones, providing second-language learners with feedback to help improve their Mandarin pronunciation.
