Sentence Production in a Discourse Context in Latent Aphasia: A Real-Time Study

Area of Science:

• Neurolinguistics
• Speech-Language Pathology

Background:

• Aphasia can affect spoken language production.
• Latent aphasia presents subtle challenges in discourse.

Purpose of the Study:

• To identify factors influencing spoken sentence production in adults with latent aphasia.
• To analyze discourse patterns in latent aphasia.

Main Methods:

• Analysis of discourse samples from AphasiaBank (Cinderella story).
• Speech analysis software used to measure pause durations (silent and filled).
• Comparison of latent aphasia, anomic aphasia, and neurotypical controls using mixed-effect models.

Main Results:

• Latent and anomic aphasia groups showed significantly longer pauses than controls.
• Pause duration was not affected by syntactic complexity.
• Both clinical groups paused more before longer sentences compared to shorter ones.

Conclusions:

• Reduced processing speed is a key factor in compromised spoken sentence production in latent aphasia.
• Increased pausing in latent aphasia impacts discourse fluency and cognitive load.
