General Overview

This corpus is from a large-scale clinical trial focused on predictors of therapy-induced language outcomes in chronic aphasia: POLAR, Predicting Outcomes of LAnguage Rehabilitation in aphasia. POLAR involved a cross-over design where half of the participants with chronic aphasia were randomized to first undergo 3 weeks of speech-language therapy (SLT) (5 times/week) focused on phonological processing and then receive 3 weeks of semantically focused SLT with a 4-week break between the two SLT phases. The remaining half of participants were randomized to receive semantic SLT first and then phonological SLT during the second therapy phase.

The participants did 3 tasks from the AphasiaBank protocol at each test time: Broken Window picture description, Cinderella storytelling, and Sandwich procedural discourse (peanut butter and jelly). Note: The Sandwich task was administered with a photo of a peanut butter and jelly sandwich. It was not the photo from the AphasiaBank standard discourse protocol that was offered to people who were having difficulty with the task.

MRI scans for these participants can be found at Open Neuro. To match scan numbers to transcript numbers, you can use this key. The scans are in Nifty (nii) format and may include anatomical (anat), functional (func) or diffusion-weight imaging (dwi) scans across several sessions. They need to be downloaded one-by-one. The MRIcroGL program which can be downloaded from here provides a good way to view these scans on the desktop.
