Summary
Script training improved speech fluency and connected speech measures in individuals with nonfluent/agrammatic primary progressive aphasia (nfvPPA). This intervention demonstrated significant gains in speech production and timing post-treatment.
Area of Science:
- Speech-language pathology
- Neuroscience
- Linguistics
Background:
- Script training is a speech-language intervention that uses repeated rehearsal of functional content to improve fluent connected speech.
- It has shown benefits for individuals with aphasia and apraxia of speech, including those with primary progressive aphasia (PPA).
- Previous studies on script training in nonfluent/agrammatic PPA (nfvPPA) focused on limited outcome measures, leaving potential benefits to connected speech less understood.
Purpose of the Study:
- To evaluate the utility of a broader range of connected speech measures for assessing script training outcomes in individuals with nfvPPA.
- To characterize the effects of Video-Implemented Script Training for Aphasia (VISTA) on various speech production and timing parameters.
- To explore the application of automated and semi-automated analysis tools in quantifying treatment effects.
Main Methods:
- Twenty individuals with nfvPPA participated in the study, receiving Video-Implemented Script Training for Aphasia (VISTA).
- Trained and untrained script topics were assessed pre- and post-treatment.
- Speech samples were transcribed and analyzed using Computerized Language ANalysis (CLAN) for fluency, grammar, and informativeness, alongside acoustic measures of speech timing.
Main Results:
- Participants showed significant improvements in words per minute, reduced fluency disruptions, increased mean length of utterance, enhanced grammatical complexity, and a higher proportion of open to closed class words for trained topics.
- A reduction in mean and variability of syllable duration and mean pause duration was observed.
- The speech-to-pause ratio increased, indicating improved speech flow.
Conclusions:
- Script training effectively promotes fluency of connected speech in individuals with nfvPPA.
- The study highlights the value of comprehensive, automated, and semi-automated speech measures in evaluating the impact of speech interventions.
- These findings support script training as a beneficial therapy for improving connected speech in nfvPPA.

People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
