Biography

I am an associate professor at UCLA in the Department of Linguistics, and director of the UCLA Language Processing Lab. My research investigates how language users develop a sufficiently rich linguistic meaning during online comprehension. Recent topics include the processing of ellipsis and the assignment of focus, as well as the role of other semantic, pragmatic, and prosodic defaults in sentence interpretation.

I am committed to using experimental methods in my research, including Internet based questionnaires, corpora, and online methods such as self-paced reading and eye tracking. See this page for a description of the various methods and data collection tools used in the lab.

Before UCLA, I was an assistant professor at Pomona College, in the Department of Linguistics & Cognitive Science.

I am an organizer for the California Meeting on Psycholinguistics (CAMP), and hosted the inaugural meeting at UCLA in 2017. CAMP 2018 was held at the University of Southern California. CAMP 2019 was held at UC Santa Cruz. CAMP 2021 will be held virtually at UC Irvine.

Finally, I lead the Psycholinguistics / Neurolinguistics Seminar most quarters; the current schedule may be found here.

Research interests

How does the language processing system make efficient use of multiple sources of information to produce a sufficiently rich representation? What information may go underspecified? How does grammatical knowledge constrain representations considered during online sentence processing?

Teaching

Courses for 2020-2021

Spring 2021. Language Processing [Ling 132]

Course description:

Psycholinguistics is a relatively young, but rapidly growing, discipline that addresses how language might be realized as a component within the general cognitive system, and how language is comprehended, produced, and represented in memory. It is an interdisciplinary effort, drawing on research and techniques from linguistics, psychology, neuroscience, and computer science, and utilizes a variety of methods to investigate the underlying representations and mechanisms that are involved in linguistic computations.

This course concentrates on (i) uncovering and characterizing the subsystems that account for linguistic performance, (ii) exploring how such subsystems interact, and whether they interact within a fixed order, and (iii) investigating how the major linguistic subsystems relate to more general cognitive mechanisms.


Spring 2021. Seminar in Semantics [Ling 252]

Resources

Eye tracking corpora and tools

Los Angeles Reading Corpus of Individual Differences

The Los Angeles Reading Corpus of Individual Differences (LARCID) is a corpus of natural reading and individual differences measures. The corpus is currently a feasibility pilot of eye tracking data collected from 15 readers. Five texts from public domain sources were included. In addition to the eye tracking measures, a battery of individual difference measures, along with basic demographic information, was collected in a separate session. Individual difference measures included the Rapid Automatized Naming, Reading Span, N-Back, and Raven’s Progressive Matrices tasks.

Pilot data, write up, and R-markdown files can be found on this Open Science Framework page. Comments welcome!

Robodoc

Robodoc is a Python program that automatically cleans eye tracking data of blinks and track losses. This new version improves usability and command line options. Learn more about this handy code here.



Corpus tools

Embedded appositives corpus

The Embedded Appositives Corpus is an annotated collection of 278 sentences containing appositives embedded syntactically in the complement of propositional attitude predicates and verbs of saying, drawn from 177 million words of novels, newspaper articles, and TV transcripts. Intended to inform work on appositives, conventional implicatures, and textual entailment. Includes a Javascript interface, an XML corpus, and a short write-up describing the data and their theoretical relevance.

NPR Corpus scraper

THE NPR Corpus scraper is a collection of Python programs built to crawl NPR and download transcripts into XML format, with links to audio files of radio interviews into a directory. It can be tweaked to crawl other news sites. Note: this tool requires a working knowledge of Python. To be posted with instructions soon!



The script downloads the Linguist List job posting archives for the years specified below. After some reformatting, it removes all but tenture track job postings and categorizes the jobs according to keywords listed in the posting. The method for categorization largely follows previous efforts; see the Language Log postings on the 2008 data, 2009 data, and 2009-2012 data.



A fully executable R Markdown tutorial is hosted on github. To clone with git into a folder called scrape, run this command from the terminal:

git clone https://github.com/jaharris/linglist-scrape.git scrape


Odds and ends

CombineResults.rb.

Simple to the point of trivial, this Ruby program writes results from Linger’s .dat files to a single file with the experiment name automatically appended along with the number of subjects run. Primarily for command line phobics. If Ruby is installed on Windows, simply place in the same folder as your .dat files, and then double click on the icon to run. Also works with Mac and Linux.
