Ph.D. in Hearing, Speech, and Language Sciences
The Ph.D. program in Hearing, Speech, and Language Sciences prepares students with a masters or clinical doctorate in a related field (e.g., Au.D., M.S. in SLP) for faculty and research positions in universities and other research facilities. The Ph.D. program consists of coursework in research methods and statistics, professional issues (teaching, grant-writing), and advanced topics in hearing, speech, and language sciences. Students are also expected to be continuously enrolled in ASL classes until they have successfully completed (or tested out of) PST 303.
Additional requirements include a qualifying examination, a supervised practicum in higher education teaching, a research internship leading to a pre-dissertation project, a candidacy examination, and a dissertation that addresses a critical question in hearing, speech, and language sciences. Students in the HSLS Ph.D. program have research opportunities within the department, as well as with other Gallaudet departments and affiliated programs in other universities and research sites.

Summary of Requirements
Year I – Fall (12 Credits)
Note: Excluding ASL from total credits
This introductory course sequence develops the primary statistical concepts and techniques needed to conduct research. This course presumes no previous statistical background other than college-level algebra or its equivalent. The course goal is to develop many of the basic conceptual theories underlying statistical applications, while
also developing a critical perspective toward statistics. Students will develop skills in descriptive statistical analysis, simple correlation procedures, and hypothesis testing. Computer-assisted analysis will complement course work.
Discussion of the theory and applications of inferential statistics, including sampling, estimation, confidence intervals, inferences, effect sizes and hypothesis testing as well as descriptive statistics, validity and reliability. Specific statistical techniques such as t tests, Chi Square, one way and factorial analyses of variance, correlations, simple and multiple regression as well as an introduction to trend analysis will be presented. Lab experiences in using SPSS or similar computer programs for analyzing data will be provided. Evaluations of statistical methods used in published research will be discussed.
The series of Advanced Topic classes are designed to introduce foundational issues in Hearing, Speech and Language Sciences. It is designed to explore theories, research methodologies and translation to clinical practice in each of the three areas. Students can expect to build a foundation of knowledge that can inform research in hearing, speech, and language sciences. The Speech Science Course include topics in speech acoustics, speech production and speech perception. In speech acoustics, students will study the physics of sound waves and how it is created and transmitted. In speech production, methods and tools for addressing typical and atypical generation of speech are examined. In Speech Perception, the many factors in hearing, seeing and feeling speech is studied. Focus will be given to different theoretical account and models of speech acoustics, production and perception.

The Language Science Course will include the study of theoretical constructs (principles, parameters and non-linear phonology), methods (psycholinguistics, grammaticality judgment, reaction time) and terminology (cohesion, agreement, features) of the Language Sciences (linguistics, neurolinguistics and psycholinguistics).
Year I – Spring (13 Credits)
The series of Advanced Topic classes are designed to introduce foundational issues in Hearing, Speech and Language Sciences. It is designed to explore theories, research methodologies and translation to clinical practice in each of the three areas. Students can expect to build a foundation of knowledge that can inform research in hearing, speech, and language sciences. The Hearing Science Course will focus on the anatomy, physiology and psychophysical (psycho-acoustics) bases of sound detection, discrimination and perception. The processing and perception of sounds (speech and non-speech) by a typical or atypical auditory system will be explored along with procedures, instrumentation and techniques employed in hearing science research.
In HSL 887 Lab Rotation it is expected that students rotate through the various laboratories in the HSLS department and research laboratories within the university under the guidance of their academic advisor. Students are expected to: (1) observe activities within the lab, (2) attend lab meetings, and /or (3) participate in ongoing research activities. Students will become familiar with the questions framing the laboratory¿s research, how each question is addressed through various methodologies, and gain hands-on experience with the steps of the scientific method. Students are expected to submit reflection papers highlighting their experience in each laboratory. Students will describe the observed theory or hypothesis, research design, analysis and clinical interpretation in hearing, speech and language sciences and relate it to their own experiences and readings.
The main purpose of the Advanced Research Design I course is to facilitate student's
integration of theory, research design, and measurement issues with knowledge of
statistical procedures needed to plan, accomplish, and evaluate qualitative and
quantitative research projects in speech, language and hearing sciences. Students will
develop their ability to locate, review, and critically evaluate research studies. The
course will cover the proper format for research proposals and reports, measurement
issues, and sampling. In addition, the student is introduced to quantitative and
qualitative approaches to research. The student will develop critical analysis abilities
using the criteria of validity and reliability as explicated in experimental design
principles. Specifically, the course will focus on (1) Identifying and formulating
research questions, (2) Completing a literature search and literature review, (3) non-experiment (qualitative) research design (case studies, survey research), (3)
experimental research and levels of evidence, (4) research participants and sampling,
(5) data analysis: describing different types of data, (6) data analysis: inferential
statistics, (7) research outcomes.
Qualifying Examination at end of semester
Year II – Fall (11-14 Credits)
This course is intended to develop professional competencies in three areas: (a)
knowledge and use of the following approaches to research: experimental, quasiexperimental, causal-comparative, qualitative, and correlational research, and (b) develop knowledge of experimental research design options, (c) development of formal research proposals. This course will address major concepts, issues, and techniques of quantitative research methods.
In this course students are introduced to various pieces of software, hardware, and laboratory techniques common to research in speech, language, and hearing sciences. Through various teaching methodologies students learn to use the basic tools that are important for research in hearing, speech and language sciences with a focus on gaining practical, hands-on experience. The goal of this course is to prepare students to critically make decisions regarding laboratory instrumentation for experiments.
This seminar is a pre-requisite for PhD students in the HSLS PhD Program who will be enrolled in a Practicum in University Instruction the following Spring semester. Students in this seminar become familiar with trends and issues in higher education instruction and supervision of interns in higher education Audiology and SLP programs.
It is expected that every student complete at least one year of supervised research under the mentorship of an established researcher/faculty member. Students may complete this requirement during their full-time residency year (during the first three years of matriculation) in which the student is required to spend at least 15 hours per week in supervised research activity. This is to provide students with an opportunity to work with and learn from established researchers in transitioning previously acquired academic knowledge and skills to applied knowledge and skills. The main goal is to provide students with a sound overview of scientific research to prepare them to begin doctoral research. Students' ability to apply the scientific method to speech, language, and hearing research will be advanced. Students will refine their ability to evaluate the research literature, formulate a research question, and develop a research design. Ideally, research practicum should culminate in one or more of the following: (1) submission of an article for publication, 2) submission for presentation at a referred conference, (3) pre-dissertation project or pilot data for their dissertation.
Year II – Spring (11-15 Credits)
In the Ph.D. Professional and Ethical Issues Seminar course addresses
topics of interest to doctoral students who plan to seek faculty positions in academic
settings. Topics addressed include mentor-mentee relationships, job hunting and
interviewing, academic career development, curriculum vitae, electronic portfolios,
professional organizations serving college and university professors, tenure and promotion decisions, professional ethics, professional liability, mission statements and strategic objectives in academic settings, the roles of administers and faculty in curriculum development, faculty evaluation, and shared governance. This course will include discussion and readings of topics concerning scientific, research and medical ethics and practical issues in the scientific advancement of speech, language and hearing sciences. Discussions will also center on cultural considerations on scientific advancements in the field.
