Find out more about the tools used in the lab to conduct our research.
The lab is home to several tools for online experimentation. We house an anachoic chamber for phonetics recording and presenting auditory stimuli, as well as various eye trackers and an EEG recording system for collecting ERP data.
SR Eyelink 1000 We use this tower-mounted eye tracker, which uses a high speed camera to record eye movements at up to a 2000 Hz (twice per millisecond) to study reading in a natural setting. The camera can also be used with a desktop mount to permit free movement of the head.
See lab video on the Sign Up page for an overview of a reading experiment.
BioSemi ActiveTwo We recently acquired use of an BioSemi ActiveTwo EEG recording unit. The system records from 64 active electrodes to measure electromagnetic potentials from the scalp.
Ibex Farm. Alex Drummond's web-based tool for collecting judgments online. My tutorial from a talk at USC on how to use Ibex Farm with Amazon's Mechanical Turk, along with a handy Excel script for formatting the materials, and a sample R-file, can be found here.http://spellout.net/ibexfarm
English Lexicon Project. Powerful database for collecting lexical characteristics such as frequency, neighborhood size, bigrams, etc.http://elexicon.wustl.edu
English pond. Another tool for extracting lexical characteristics from a list of words from English, Spanish, French, Dutch, and German. Particularly useful for determining neighborhood size.http://clearpond.northwestern.edu/englishpond.html
UCLA Corpus resources. A summary with links of the corpora accessible on the department's server.http://www.linguistics.ucla.edu/general/CorporaSummary/Corporasummary2.htm
Mouse tracker. For presenting mouse trajectory experiments, with a very intuitive interface.http://www.mousetracker.org/
Linger. A versatile tool for lexical decision, priming, and self-paced reading. Requires the Tcl/Tk framework (and the occasional hack).http://tedlab.mit.edu/~dr/Linger
UMass eye tracking software. Multiple programs developed by Chuck Clifton and others at UMass Amherst for all aspects of text based experiments. For use with the SR Eyelink II or 1000.http://www.psych.umass.edu/eyelab/software
Experiment builder. From SR Research, a nice suite of presentation and analysis tools for just about any type of eye research. We've used it for a pupillometry experiment. Great software support, too.http://www.sr-research.com/eb.html
