Both vulnerabilities to COVID-19 and childhood trauma have deep roots in health inequities. Children of color especially risk severe COVID-19 illness, with long-term effects that amplify existing health disparities, including trauma exposure. Similarly, children of color report more adverse childhood experiences (ACEs) than non-Hispanic White children. ACEs and other potentially traumatic events are associated with lifelong physical and psychological health problems. Policy must prioritize health equity (the absence of differences in health care access, quality, and outcomes based on ethnicity, race, and socioeconomic status). A trauma-informed approach emphasizes recovery and resilience. Principles of health equity can join with trauma-informed policy and practice for families and communities to help mitigate the effects of childhood trauma during the pandemic and beyond.
Recognition of target keywords in CRM sentences in the presence of competing CRM sentences has been shown to depend upon both the rhythmic context of target and background speech and F0 differences between target and background speakers. The present study investigated the role of the relative timing of target and background keywords for background keywords that were presented either in isolation (Experiment 1) or embedded within their associated background context (Experiment 2) for target and background material that was spoken by the same male talker. In Experiment 1, onset asynchrony of target and background keywords varied between –200 ms and 200 ms. Results showed an asymmetric U-shaped performance curve where (1) target recognition improved with increasing deviation of background keywords from the expected onset timing of target keywords and (2) target words were better recognized when they began before background keywords compared to when they began after. In Experiment 2, where background keywords were embedded within their original CRM context, performance was reduced to chance for both an intact background rhythm condition and a range of altered background rhythm conditions. Results will be discussed in terms of a selective entrainment hypothesis and the role of F0 differences in speech segregation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
