Our laboratory is well equipped for a wide range of experiments and computational modeling.
Behavioral Research: Our laboratory has two large rooms equipped with several PC computers for testing human participants in experiments. Our laboratory also has a meeting room with a large conference table, an office, and an anteroom for storage.
Data Analysis. We have several Mac PC computers equipped with a wide range of software for data analysis and presentation, including MATLAB, SPSS, Sigmaplot, Microsoft Office, and other programs.
Computational Modeling. In addition to laboratory Mac and PC computers for model development, we make use of the high performance computing facilities at Vanderbilt’s Advanced Computing Center for Research and Education (ACCRE). ACCRE currently maintains a beowulf cluster with well over 2000 processing cores and a multi-terabyte storage system. Our laboratory also participates in a large-scale data sharing grid supported by the TDLC and ACCRE.
Eye Tracking. Our laboratory shares an SR Research EyeLink II eye tracking system.
Data, Models, and Supplemental Information
We are just begining to archive data and supplemental information from our publications. More will come later (I’d say soon, but I’d be lying).

Working simulations of the independent race model and the interactive race model described in Boucher, Palmeri, Logan and Schall, Inhibitory Control of Mind and Brain: An Interactive Race Model of Countermanding Saccades can be found at http://www.psy.vanderbilt.edu/faculty/palmeri/psyrev07_model/.
Working simulations of the Gated Accumulator model described in Purcell, Heitz, Cohen, Logan, Schall, and Palmeri, Neurally Constrained Modeling of Perceptual Decision Making can be found at http://catlab.psy.vanderbilt.edu/wp-content/uploads/PurcellHeitzCohenLoganSchallPalmeri_PublicCode1.zip
I’ve compiled a bunch of useful resources for computational modeling as a part of a graduate-level modeling course I teach : PSY318 Computational Modeling.
I don’t believe in reinventing the wheel especially when someone else has done a much better job than I might have. Here are some web sites I’ve found that are useful resources:
John Kruschke’s Virtual Mentor for Graduate Students This is a great resource for beginning graduate students (and beginning faculty mentoring graduate students for the first time). Thanks John for putting this together.
Diffusion Model Analysis Toolbox (Vandekerckhove and Tuerlinckx) Thanks to Joachim and Francis for developing this great suite of MATLAB tools for simulating and fitting the diffusion model.
G*Power3 is an easy-to-use general purpose package for statistical power calculations.
Professional Development Information is a web site I put together for our graduate students in Psychological Sciences at Vanderbilt. It gives some useful information on creating a scientific vita and has links to a number of useful sites on early career development and grant writing.
(more to come whenever I get a chance)
Institutional Resources and Research Centers
Our research is enhanced by our affiliation with research centers that provide important funding and support for research infrastructure.
Temporal Dynamics of Learning Center (TDLC). Our laboratory is part of the Perceptual Expertise Network (PEN), which is now one of four research networks in a new NSF funded Science of Learning Center devoted to studying the role of time and timing in human learning. The center funds some of our research as well as network activities of PEN.
Perceptual Expertise Network (PEN). PEN is a collaborative research network working together to explore how different brains approach object recognition and categorization.
Advanced Computing Center for Research and Education (ACCRE). ACCRE is the high performance computing center at Vanderbilt. It supports a cluster of well over 1000 processors on linux computers that we regularly use in our computational modeling research.
Center for Integrative and Cognitive Neuroscience (CICN). CICN provides important administrative and computer support for many aspects of the research done in our laboratory.
Vanderbilt Vision Research Center (VVRC). The VVRC provides our laboratory administrative, computer, and graphics design support.
Vanderbilt University Institute for Imaging Science (VUIIS). VUIIS supports a 3T and 7T research-only MR scanner for human brain imaging research at Vanderbilt.

To the tune of Dreadlock Holiday
Lyrics by Suzie Dukic (with help from Mike Mack)
I was walkin’ down the street
Concentratin’ on truckin’ right
I heard a smart voice beside of me
And I looked round in a state of fright I
saw four scientists, one mad
The others from the gutter
They looked me up and down a bit
And turned to each other
I say I don’t like science oh no, I love it
I don’t like research no no, I love it
Don’t walk away yet
You got to show some respect
We have our doctorates
And you’re prosopagnosic
They said come back to the lab with us
They said we’ll give you some dollars
I said I don’t know my cars, man
And I’m afraid that I might holla
They said we like you, we want you
We need you for our research
You’ll see faces and greebles
While we record your blood flow properties
And EEG’sâ€¦..and I say!
I don’t like science oh no,
I love it
I don’t like research no no,
I love it
They said don’t walk away yet
You got to show some respect
We’ve got millions in grants
And a posse of students
I hurried back to the Hard Rock
Sinkin Pina Colada
I heard Gary beside me say
Would you like something harder
He said I’ve got it, you want it,
My Models are the best, and if you try ’em
You’ll like ’em, and wallow in the Research Holiday
Don’t like the Hard Rock, oh no, I love her
Don’t like Chicago, no no, I love her
He said don’t you walk away yet
Got to show some respect,
Don’t you walk away yet,
Cause you ain’t seen the owls yet
Don’t like the PI’s, no no, I love them,
Don’t like the trainees, ohhh,
I love them,
I love the Science!
