Alignment refers to the interactive use of similar words to accomplish a linguistic and cognitive "common ground" in conversations. Alignment is thought to be unconscious, relying on priming mechanisms. This occurs uniquely in conversational contexts and has been shown in choices of words, grammatical constructions, and even indirect language and gestures. This study reports a couple who demonstrated very little pretherapy alignment, using a couples-based approach. The client realized an increase in utterances and words, and no change in incoherent utterances. Her nonaphasic spouse increased his use of alignment. Naïve observers of therapy sessions perceived later sessions as more positive than earlier sessions.
