The Audiovisual Mismatch Negativity in Predictive and Non-Predictive Speech Stimuli in Older Adults With and Without Hearing Loss.

Adults with aging-related hearing loss (ARHL) experience adaptive neural changes to optimize their sensory experiences; for example, enhanced audiovisual (AV) and predictive processing during speech perception. The mismatch negativity (MMN) event-related potential is an index of central auditory processing; however, it has not been explored as an index of AV and predictive processing in adults with ARHL. In a pilot study we examined the AV MMN in two conditions of a passive oddball paradigm - one AV condition in which the visual aspect of the stimulus can predict the auditory percept and one AV control condition in which the visual aspect of the stimulus cannot predict the auditory percept.

Perceptions and Lived Experiences of Arab American Parent Participants in LENA Start: Lessons for Parent Education Programs in Minoritized Communities.

Purpose: This article investigates caregivers' perceived experience as part of the first implementation of LENA Start for Arab American families in New York City, with particular attention to the children's bilingual status as heritage speakers raised in marginalized communities within the United States.

Method: A qualitative analysis of a semistructured focus group interview conducted with five Arab American mothers who participated in the program was conducted to explore parents' perception and experience of the program using Glaserian grounded theory analysis.

Results: Parents reported more talking and reading with their children after participation, but the recorded data showed the changes were not significant.

Research Self-Efficacy and Productivity in Communication Sciences and Disorders Faculty.

Introduction: In the field of Communication Sciences and Disorders (CSD) emphasis is placed on advancing research to inform evidence based practice. However, there is little information about the research support and productivity of current faculty members in the discipline. The aims of this study are: to describe the resources and workload of faculty at different types of institutions; to examine whether self-perception of research self-efficacy differs between faculty across institution types; and to investigate whether self-efficacy, institutional factors, or workload characteristics predict research productivity.

Neural Correlates of Modality-Sensitive Deviance Detection in the Audiovisual Oddball Paradigm.

The McGurk effect, an incongruent pairing of visual /ga/-acoustic /ba/, creates a fusion illusion /da/ and is the cornerstone of research in audiovisual speech perception. Combination illusions occur given reversal of the input modalities-auditory /ga/-visual /ba/, and percept /bga/. A robust literature shows that fusion illusions in an oddball paradigm evoke a mismatch negativity (MMN) in the auditory cortex, in absence of changes to acoustic stimuli.
