| dc.description.abstract | In academic environments, the ability to comprehend written text is critical for successful learning. In spite of the importance of this skill, few programs exist for improving comprehension, especially for typically developing readers. Previous research demonstrated that cervical vagus nerve stimulation (cVNS) is a safe and effective method for driving neural plasticity. However, an invasive and expensive procedure is not practical for a reading intervention. Recent research has demonstrated that the auricular branch of the vagus nerve can be accessed non-invasively through transcutaneous auricular vagus nerve stimulation (taVNS) at the outer ear (Frangos, Ellrich, & Komisaruk, 2015). Recent work in our lab provides evidence that taVNS paired with training can improve novel letter-sound learning (Thakkar et al., under review). Thus, we hypothesized that pairing taVNS with reading would aid reading comprehension in typically developing young adults. We recruited typically developing young adult readers and verified reading ability using standard assessments. Eligible participants were randomly assigned to receive either active or sham stimulation to the posterior tragus of the left ear while reading passages and subsequently answering standard comprehension questions from the GORT-5 (Wiederholt & Bryant, 2012). Participants were scored on time spent reading, errors in reading, and reading comprehension. Data collection suggests a benefit of active stimulation on reading comprehension, as compared to those receiving sham stimulation. Implications of this work may suggest using taVNS as a novel intervention for reading comprehension, but further studies should extend the methods in a sample of struggling readers. | |
