Abstract
Script training is an effective treatment of stable (e.g., stroke-induced) and progressive
aphasia of varying severities and subtypes. The theoretical underpinnings of script
training are discussed and include fluency-inducing conditions, speech shadowing,
principles of neuroplasticity, and automatization. Script training outcomes are reviewed,
with a focus on discourse in persons with stable aphasia (PWSAs) and in persons with
primary progressive aphasia (PWPPAs). PWSAs and PWPPAs are able to acquire and maintain
short scripted monologues or conversational dialogues, with some evidence of generalization
to untrained topics and settings. Advances in both technology and access have enriched
script training protocols, so they now range from no-tech written script approaches
to high-tech audiovisual support and avatars. Advances in audio and/or visual support
promote large amounts of practice of less errorful whole-message language processing
during a fluent language inducing condition. With enough practice, users decrease
reliance on supports and independently produce scripted content. Script training can
be delivered in a variety of settings (individual, group, telepractice), lends itself
well to homework programs, and is in accordance with the principles of neuroplasticity
for neurorehabilitation. Incorporating script training into therapy programming is
advantageous throughout aphasia recovery following brain injuries such as stroke.
It is also beneficial for persons with progressive disease for prophylaxis, remediation,
and compensation. Recommendations for implementing script training in clinical practice
and future research directions are presented.
