Semantic Feature Analysis training will be provided in the language that was selected by the computational model.

SFA training entails having the speech-language pathologist (SLP) guide the participant through generation of pertinent semantic features for pictured treatment items (e.g., category membership, physical description, location of item in context, action associated with item). Treatment is applied to a set of items in the context of single-subject, multiple baseline designs so that replication of treatment effects could be evaluated within and across participants. Treatment will be administered two times per week until prescribed accuracy levels were met during treatment probes or a maximum number of treatment sessions was completed.

Semantic Feature Analysis training will be provided in the language opposite to that which was selected by the computational model.

Accuracy of naming black and white pictures that are both trained and untrained in English and Spanish will be assessed in naming tests. These tests were conducted repeatedly throughout the study, from baseline (prior to treatment) to the end of treatment. All naming responses were scored using as correct or incorrect. Proportion accuracy was calculated for each set of items for every testing session. Baseline scores were compared to end of treatment scores to obtain individual effect sizes for each sets of items for each participant.

The PALPA/Evaluación del Procesamiento Lingüístico en la Afasia (EPLA) is a standardized assessment for reading simple words and spoken words in both English and Spanish out of 30 words.

The BNT is a standardized naming assessment that includes 60 pictures that can be named in either English or Spanish.

Western Aphasia Battery:The WAB-R is a standardized, gold-standard assessment for determining the presence, type, and severity of post-stroke aphasia, with excellent reliability and validity. The WAB-R measures performance across a variety of expressive and receptive language domains and takes approximately 45-60 minutes to administer. Weighted performance across four of these domains - spontaneous speech, auditory verbal comprehension, repetition, and naming/word finding - yields a composite score, the WAB-R Aphasia Quotient (AQ). The WAB-R AQ is an impairment-based metric that reliably indexes aphasia severity across different aphasia subtypes. Range is 0 t0 100.

The Pyramids and Palm Trees is a non-verbal (language-independent) semantic processing assessment that includes 3 pictures of which the person has to decide which two go together. There are 52 items in this test with a range of 1-52.
