Narrative Comprehension by People With Acquired Brain Injury

Part 1 Experimental Procedures: Written or Spoken Paragraph Level Measure o Participants will read or listen to 12 paragraph length narrative stories in the following 3 conditions: (a) written text only, (b) auditory output only (i.e., synthetic speech - David), or combined written text and auditory output. Participants will answer 10 questions regarding the information contained in each of the 12 stories. Anticipated time requirements: 1 to 2 sessions lasting about 60 minutes each.

Part 2 Experimental Procedures: Repeated Exposures

• Independent Training Session Practice

• To prepare the participants for independent practice (exposure) to the Synthetic 1 Condition during home training, the researchers will complete the first Independent Training Session with the participant within the clinic environment to verify participants understanding of the experimental procedure.

• The researchers will provide written instructions with simplified language and picture support to remind the participant of the practice instructions.

• Independent training sessions will utilize the Test of Silent Reading Efficiency and Comprehension (TOSREC) sentences recorded using the Synthetic 1 Voice Condition and the Digitized Voice Condition. TOSREC sentences are simple sentences presented at 1st, 2nd, and 3rd grade levels. Example sentence include: "A cow is an animal", and "Bears go to school". The participants will respond "yes" or "no" to each of 30 TOSREC sentences presented in a systematically randomized order. "Yes" and "no" responses will be recorded using active areas on the iPad created using a computer program designed for delivering stimuli (e.g., Blackboard, Canvas). All practice will be completed via the computer platform (e.g., Blackboard, Canvas) on the iPad. All 30 practice items should be completed in one sitting; however, the participant can take a break 5-10 minutes break during practice if needed.

• During this first Independent Training Session Practice, the researcher will provide the participant with verbal and written instructions regarding how to access each item and ensure that the participant understands the task prior to independent practice.

• Independent Training Sessions

• Participants will be given an iPad with Wi-Fi capabilities to use in their home (as well as a charger. Alternatively, participants may choose to use their own iPad.

• The researchers will instruct each participant to listen to and/or reading 15 sentences per day per condition (Synthetic 1 and Digitized Sentence presentations). The researchers will provide written instructions with simplified language and picture support to remind the participant of the practice instructions.

• The participants will respond "yes" or "no" to each of the 30 TOSREC sentences presented in a systematic randomized order. All 30 practice items should be completed in one sitting; however, the participant can take a 5-10 minute preach during practice if needed.

• Participants will receive feedback about overall percentage performance accuracy at the end of each daily session.

• All practice will be completed via the computer platform (e.g., Blackboard, CANVAS) on the iPad. Participants will practice for a period of two weeks (12 sessions). This is expected to take the participants no more than 15 minutes per day. The person will be asked to complete the practice up to 6 days per week. The participant will decide the days and times of practice as fits his or her schedule.
