Associate Professor of Cognitive Science
In 1990, she was awarded a Rhodes Scholarship which enabled her to pursue an M.Phil. in Theoretical Linguistics at Wolfson College, Oxford University. She received her Ph.D. in Psychology from the University of Pennsylvania in 1998.
She is interested in the structure of lexical representations and in applying electrophysiological techniques, in particular event related potentials, to the investigation of cognitive phenomena. Her thesis work consisted of investigating the relationship between orthography and lexical stress in English.
Her current research is focused on examining how complex words are represented in the mental lexicon. She teaches courses in cognitive psychology, cognitive neuroscience and psycholinguistics.
Words are the basic linguistics units of a language and the ability to recognize a word is a fundamental component of reading. For many years most of the research in reading was conducted in English, and it was assumed that what was true for reading English words would also be true for words in other languages. However, many languages differ in striking ways from English and studying these languages can be useful in illustrating the different ways that people approach reading. In this class we will look at the structure of words in the Semitic languages-Hebrew and Arabic-and consider how differences in word structure can influence the ways in which we read. Students will learn how to read and critically evaluate the scholarly literature on the psychology of reading. No knowledge of Hebrew or Arabic is required.
This course is an upper-level research seminar designed for students who wish to learn electrophysiological techniques and how to analyze electrophysiology data. Course requirements will consist of reading primary research articles, executing an event related potential (ERP) research project on visual processing, and analyzing the data that is collected. The class will cover all elements of setting up an ERP research project and we will focus on both the theory and practical aspects of developing and running research study. The data analyses methods will cover a range of techniques from classical univariate statistical techniques to more advanced multivariate statistical learning methods. Students are expected to work independently.
The problem of explaining how the brain enables human conscious experience remains a great mystery of human knowledge. This course is an introduction to cognitive neuroscience in which we will attempt to examine the neural underpinnings of the mind's complex processes, paying particular attention to vision, attention, and memory. Cognitive neuroscience incorporates elements of physiological psychology, neuroscience, cognitive psychology and neuropsychology. In this course we will become familiar with the tools of research used in cognitive neuroscience and with questions that motivate researchers in the field. Students will be expected to read and critically analyze articles from the professional scientific literature.
The purpose of this course is to introduce you to human cognition or the scientific study of the mind. We will take an information processing view of psychological functions. Thus we will spend much of our time discussing information, in the form of mental representations, and how this information is transformed in the mind. We will examine how perceptual information enters the mind, how attention is used to select from the array of available incoming sensory information, how knowledge is encoded, stored in and retrieved from memory, how information is conveyed to others via language, and how information is used in reasoning and decision making. Students will be expected to read and critically analyze articles from the professional scientific literature.
Human social interaction relies upon the ability to correctly attribute beliefs, goals, and percepts to other people. This set of meta-representational abilities--a "theory of mind"--allows us to understand the behavior of others. Individuals with autism are often thought to lack a theory of mind as they show impairments on tasks testing this ability, as well as impairments on tasks involving language and face processing. The goal of this course was to examine the links between these three domains: language, face processing and social cognition, and the role each plays in helping us navigate the social world. Prerequisite: One prior course in cognitive science, cognitive psychology, social psychology, developmental psychology, physiological psychology, comparative psychology, linguistics, neuroscience or any other relevant area.
The course will focus on the acquisition of two or more languages by both children and adults. We will look at how two or more languages are represented in the mind of an individual and ad the mental processes that allow individuals to produce and understand sentences in each language. Questions that we will consider include: Who is considered bilingual and what are the criteria for 'knowing' a language? How does bilingualism influence linguistic and cognitive development? How does the cognitive system cope with the need to develop efficient processing mechanisms for two or more different languages and maintain separate access and representational mechanisms for each language? How is language is represented in the bilingual brain?
This course is an upper-level research seminar designed for students who wish to learn electrophysiological techniques and how to apply those techniques to answer research questions in the domain of cognitive psychology and cognitive neuropsychology. In this year's course students will help design a study of attention, run participants, and analyze the data. Additionally, they will have the opportunity to develop an original research project from conception through piloting participants. Course requirements will consist of reading primary research articles, designing, and executing an event related potential (ERP) research project. The class will cover all elements of setting up an ERP research project and we will focus on both the theory of electrophysiological research techniques as well as practical aspects of developing and running a research project. Prerequisite: one prior course in cognitive psychology, neuroscience, computer science or other relevant area.
Language is paramount among the capacities that characterize humans. We hold language as a marker of our humanity, and by understanding language we assume that we will understand something important about ourselves. In this course we will ask, and try to answer questions such as the following: What's so special about language? How do we produce sentences? How do we understand them? What might cause us to fail at either task? What is meaning, and how does language express it? Is our capacity for language a biological endowment unique to the human species?
