NCT03309930

Brief Summary

The purpose of this two phase study is to evaluate comprehension by people with acquired brain injury. The phase 1 portion of the study will examine comprehension of narrative paragraphs under 3 conditions: (a) written text only, (b) auditory output only (i.e., synthetic speech - David voice) or combined written text and auditory output. The phase 2 portion of the study is to evaluate comprehension of sentences and paragraphs produced with computer generated (synthesized) speech and digitized natural speech after multiple exposures.

Outcome Measures

Primary Outcomes (2)

  • Comprehension Across Conditions (Study 1 of 2)

    Participants will answer 10 multiple choice questions regarding the information contained in each of the 12 stories presented in 3 conditions: (1) written text only (b) auditory output only and (c) combined written text and auditory output .

    Comprehension accuracy across conditions will be assessed over 1 to 2 days.

  • Repeated Exposure to Digitized and Synthetic Speech (Study 2 of 2)

    Participants will answer 30 yes/no questions per session. Comprehension percentage accuracy will be measured over the course of 2 weeks

    2 weeks

Secondary Outcomes (2)

  • Comprehension Generalization

    measured 1 week and 4 weeks post termination of treatment

  • Perceived Comprehension Accuracy

    measured 1 week and 4 weeks post termination of treatment

Study Arms (1)

Comprehension Acquired Brain Injury

EXPERIMENTAL

All participants will be exposed to 3 conditions: (a) written text, (b) auditory output (synthetic speech), and combined conditions for study 1. For study 2 participants will be repeatedly exposed to synthetic speech output to determine the influence on comprehension. Participants are not required to participate in both studies.

Behavioral: Comprehension Acquired Brain Injury

Interventions

For study 1 participants will be exposed to 3 conditions as stated in previous descriptions and will last 1 to 2 sessions. Study 2 will begin with 1 session with the researcher lasting about 30 minutes. Then participants will be asked to complete practice at home for about 15 minutes each day for 2 weeks using a computer/iPad. Study 2 Post Testing and Maintenance Sessions 1 and 2: approximately 60 minutes per session.

SINGLE GROUP
Model Details: During Study 1 participants will be exposed to three different conditions: (a) written text only, (b) auditory synthetic speech output only and (c) a combined condition (written and auditory output). During Study 2 participants will be provided repeated exposure to synthetic speech. Participants can participate in 1 or both studies with 1 study results not being dependent on the other study. .
