Lynne NygaardProfessor

Biography

Dr. Nygaard received her B.A. in Psychology from Barnard College and received her Ph.D. in Cognitive Science from Brown University in 1991. She was an NIH Postdoctoral Trainee in the Department of Psychology at Indiana University and joined the Emory faculty in 1995. Her research examines the perceptual, cognitive, biological, and social underpinnings of human spoken communication.  In particular, her research assesses the perceptual and cognitive flexibility found in language users across cognitive and social contexts and the types of experience that promote or inhibit behavioral and neural plasticity.  Her laboratory uses a variety of methodologies including behavioral assays, eye tracking, linguistic and acoustic analyses, and neuroimaging.

Research

My research seeks to develop an understanding of human communication. I am interested in how listeners interpret a talker’s intentions, thoughts, and feelings, using both linguistic and non-linguistic aspects of spoken language. Speech is a highly complex signal. Speakers convey information intentionally with the syllables, words, and sentences that they utter. In addition, however, an enormous amount of information is conveyed through a speaker’s individual vocal characteristics and style. Spoken language requires that the listener integrate what is being said with how it is being said. Understanding the interplay between the perception of the words and sentences of spoken language with the processing of non-linguistic properties of speech is essential for a complete account of spoken communication.

Current Projects

Perceptual Learning of Voice and Accent. This project is designed to examine the role of talker and accent familiarity in spoken language. We have been studying how perceptual learning of particular talker’s style of speech influences listeners’ ability to understand the linguistic content of these utterances.

Sound Symbolism. This project explores instances of linguistic reference that involve non-arbitrary relationships between linguistic symbol and real world reference. We are exploring the extent to which aspects of linguistic form resemble external referents in natural languages and the implications of this kind of sound symbolism for language representation and use.

Auditory Imagery During Reading. This project explores the characteristics of auditory imagery for speech. Our studies examine whether readers simulate or image characteristics of human speech such as speaking rate and tone of voice when reading text passages. Of particular interest is whether the linguistic representations that are accessed during reading are auditory in nature? Do readers engage in a type of auditory imagery for speech when reading text?

Prosody and Meaning. This project is designed to examine the influence of tone of voice on spoken word recognition. We are interested in the integration of meaningful prosody, both emotional and non-emotional, with the semantic content of words and sentences. Of particular interest is how and at what point in the processing of spoken words listeners integrate tone of voice with linguistic content and whether this integration helps listeners to infer word meaning.

Social Expectations and Spoken Language Use. This project examines the ways in which social expectations or stereotypes influence spoken language communication. We are interested in the expectations that are formed when hearing talker- and group-specific properties of spoken language and how these expectations influences ongoing language processing and representation. Of particular interest is the extent to which social expectations influences our tendency to vocally accommodate or imitate conversational partners.
