Abstract Semantic Association Network Training (AbSANT) Each session will be 2 hours long and will occur twice each week for a total of 20 sessions.
Behavioral: Abstract Semantic Association Network Training (AbSANT)
In each session, the participant will be asked to categorize words, choose/discuss semantic features for each word that accurately describe the word, and generate as many words as possible within a category.
- Therapy Effect Size: Change in word generation performance from pre- to post-treatment measured using a version of Cohen's d [ Time Frame: At baseline and at approximately 10 weeks (i.e., the end of therapy) ]The mean of the baseline scores is subtracted from the mean of the post-treatment scores, and then divided by the standard deviation (SD) of the baseline scores. 6.5-8 is considered a small effect size, 8-9.5 is medium, and above 9.5 is large.
- Change in fMRI activation patters from pre- to post-treatment [ Time Frame: At baseline and at approximately 10 weeks (i.e., the end of therapy) ]Blood-oxygen-level-dependent MRI signal measured during task and rest and subjected to statistical tests of significant change from pre- to post-treatment.
