Structural Priming Treatment in Aphasia: The Role of Lexical and Abstract Syntactic Representations.

PMID 41124315WHAT IT FOUND
Structural priming improved sentence production in aphasia, with gains maintained at one week.
Crucially, aphasic patients learned better when prime and target sentences used different verbs. Same-verb training, which helps healthy speakers, actually reduced gains in this group.
Key findings
01Participants with aphasia showed significant improvements in sentence production accuracy from baseline to one-day posttesting, and these gains were maintained at one-week posttesting.
02In participants with aphasia, treatment gains were greater in the different-verb condition compared to the same-verb condition, an effect opposite to that seen in healthy controls.
03Improvements generalized to untrained items, as exposure to specific stimuli during training did not affect accuracy levels at posttesting.

What it does not show
The study included only PWA with mild-to-moderate aphasia who could already produce some simple sentences, so results may not apply to severe aphasia. Maintenance of gains was only assessed up to one week post-training; longer-term retention is unknown. Generalization was tested to untrained items within the same modalities (production/completion), but not to other communication contexts like conversation or narrative. The study was a Phase 1 pretrial design with a relatively small sample (24 PWA), limiting certainty regarding efficacy compared to a full RCT.
Declared interests
This study was supported by the National Institute on Deafness and Other Communication Disorders Grant R01DC019129. No conflicts of interest involving commercial sponsors or authors declaring financial ties to treatment providers were reported in the provided text.
The easy way to misread this
Do not interpret the lack of benefit from same-verb training in PWA as a failure of structural priming. The treatment was effective; the specific component of lexical overlap was not. Additionally, do not assume these results apply to severe aphasia, as all participants had mild-to-moderate deficits and retained some sentence production ability.
