Welcome to Computational Models of Aphasia at the
University of California,
Irvine's Auditory & Language
This site draws much of its inspiration from the Aphasia Modeling Project.
This website provides statistical methods for applying the two-step, interactive model of lexical access to picture naming responses (Foygel & Dell, 2000).
Users may enter naming response frequencies to obtain Bayesian point and interval estimates of the S-weight and P-weight parameter values with the best fit, or users may enter S-weight and P-weight parameter values to obtain naming response probabilities.
Please contact Grant M. Walker for questions or comments regarding the model or the theory behind it.
Please contact Grant M. Walker for technical questions about the model's implementation, or to report a problem with this web page.
