Speech and Language Science Labs
Bilingual Child Language Research Lab
Vera Gutierrez-Clellen, Director
- The Bilingual Child Language Research Laboratory (BCLRL) is located in the Speech, Language and Hearing Sciences building on campus. The BCLRL's research program focuses on studies of language in children with and without language impairment from various bilingual (Spanish-English) backgrounds.
Child Language & Cognitive Processes Laboratory
Julia Evans, Director
- The Child Language & Cognitive Processes Laboratory works with children with and without Specific Language Impairment and other language disorders. The laboratory's research focuses on working memory, word learning and mental representation of words and sounds.
Cognitive Neuroscience Lab
Tracy Love, Director
- The Cognitive Neuroscience Laboratory consists of four separate research areas in the field of cognitive neuroscience: aphasia, language development, neuroimaging, and psycholinguistics.
Under the direction of Dr. Tracy Love-Geffen, the CNL's research efforts are centered on the study of human cognitive processes, with a major emphasis on language processing in adults and children throughout the life span.
Language Acquisition, Poverty, and Culture Laboratory
Sonja L. Pruitt, Director
- The Language Acquisition, Poverty, and Culture Laboratory is located in
the Speech, Language, and Hearing Sciences Building on the main campus
(SLHS 101). The mission of the lab is to foster research in child
language development and disorders. The disorder that is
primarily studied is Specific Language Impairment (SLI). The primary
research focus of the lab is to detail the vocabulary and grammar of
preschool children and children diagnosed with to improve the
assessment and intervention practices of Speech Language
Pathologists. Child language development in the context of
linguistic diversity and poverty, efficacy of prevention models for
"at-risk" populations, and the role of child language research in shaping
public policy are other areas of research that we actively pursue.
Language and Cognitive Neuroscience Lab
Karen Emmorey, Director
- The Laboratory for Language and Cognitive Neuroscience (LLCN) is located at 6495 Alvarado Road, Suite 200. The LLCN research program focuses on signed languages to ask questions about the nature of human language, about the relation between language and other cognitive systems, and about the neural systems that underlie language and cognition. The lab facilities include a filming studio, digital editing suites, an SMI head-mounted eye tracking system for measuring eye gaze, and an NDI Optotrak Certus for measuring movement. Neuroimaging research is conducted at the Center for Functional MRI at UCSD and at the University of Iowa PET Imaging Center. The LLCN provides a rich research training ground for Deaf and hearing students (undergraduate, graduate, and post-doctoral). Please click on the lab link for more information.
Language Processes Lab
Lew Shapiro, Director
- The Language Processes Lab is the primary research laboratory for Dr. Shapiro. The focus of the lab is to chart the on-line characteristics of lexical and sentence processing in college-age and older adults, and in individuals with brain damage and who have aphasia. Experimental techniques are developed that probe the language and cognitive systems as they are operating under real-time constraints. Much of this research is interdisciplinary and uses knowledge gathered from the areas of psycholinguistics, linguistics, cognitive neuroscience, communicative disorders and the speech and language sciences. One important goal is to develop accounts of language processing that can be used to describe and explain language disorders, and to develop efficacious treatments for these disorders. Another goal is to illuminate brain-language relations through lesion studies (aphasia) and neuroimaging. Undergraduate and graduate students are involved in the operations of all aspects of the lab, including designing experiments, producing digitized audio and visual materials, procuring and running research participants, analyzing data, and reporting results. Dr. Shapiro's work is funded by the National Institutes of Health.
Neuropsychology Laboratory
Beverly Wulfeck, Director
-
The Neuropsychology lab is located at the CC-Alvarado building.
It serves as the primary research and teaching laboratory for
Dr. Beverly Wulfeck, a cognitive psychologist who conducts research
in adult aphasia and childhood language disorders. The student
research lab has microcomputers with a wide range of text processing,
graphical, and statistical software packages. The lab is equipped
with video and audio taping, and language ranscription equipment
to code and process research data. The testing room is equipped
with microcomputers, dual monitors, a sound system, and a Macintosh
powerbook for computer based experiments of language processing
and attention. All computers are connected to the SDSU system
and to the Internet.
The focus of the research in this laboratory has been in the
brain bases of disorders of language and cognition in adults and
children, and in relationships between language specific disabilities
and cognitive processing deficits. Dr. Wulfeck has been a pioneer
in the development of real time processing paradigms to examine
language and cognitive processing capacities in children and adults.
In addition to her own grants, Dr. Wulfeck has been a co-investigator
in cross-linguistic studies of aphasia with Elizabeth Bates (UCSD)
for 12 years. Dr. Wulfeck's research incorporates graduate students
working to establish a child and adult language disorders research
program that builds upon the clinical populations in the SDSU
Communications Clinic. This program will provide research opportunities
for clinical faculty, as well as graduate and undergraduate students.
Phonological Typologies Laboratory
Jessica Barlow, Director
- The Phonological Typologies Laboratory is located in the Communications
Clinic Building on the main campus (CC-136). It serves as the primary teaching
and research laboratory for Dr. Jessica Barlow, a linguist who conducts research in language acquisition and
phonological disorders. The lab is equipped with four computer
workstations and analog and digital audio and video recording
devices for the analysis of speech obtained from adults, normally
developing children, and children with phonological disorders.
The lab also has equipment for use in transcription of speech
samples for research-related and course-related activities. The
primary research focus of the lab is to characterize the development
of sounds, sound patterns, and sound sequences in phonological
acquisition, and to test the adequacy of linguistic theories in
accounting for the data. The lab is beginning research on Spanish-English
bilingual phonological development as well. Another major focus
of research in the lab is treatment efficacy, specifically in
terms of how linguistic theory and issues of phonological markedness
can aid in the remediation of children with phonological disorders.
Speech Physiology Laboratory
Ignatius Nip, Director
- The Speech Physiology Lab is located in SLHS building. The focus of the laboratory is to examine changes in speech physiology and speech motor performance over the course of typical development and how these developmental changes differ in children with speech disorders. In addition, the lab investigates the relations between cognition, language, and speech motor performance interact during speech and language development. The lab primarily uses an eight-camera optical motion capture system to record and transduce the movements of the lip and jaw and also uses of electromyography, aerodynamics, and acoustic analysis techniques.
