Project description:Reduced orienting to name is an early behavioral risk marker for neurodevelopmental disorders. However, individual instances of infants' behavioral responses to name are limited in both reliability and predictive validity. Physiological responses such as heart rate (HR) deceleration may serve as more sensitive metrics than behavioral methods. As a first step toward validating HR deceleration as a candidate psychophysiological measure of name processing, we examined the congruency of behavioral and cardiac responses to name in 12-month-old typically developing infants. Infants exhibited greater median HR deceleration and spent a larger proportion of time in HR deceleration when they behaviorally oriented to their names than when they failed to do so; however, maximum HR deceleration was not related to behavioral responses. These findings provide preliminary evidence that specific HR deceleration metrics may be useful indices of infants' responses to name and may inform psychophysiological mechanisms underlying behavioral responses.

Project description:IntroductionNames are a reflection of identity and often have personal meaning. The chronic mispronunciation of names can undermine one's identity and be experienced as a microaggression. This workshop aims to provide historical context for names as well as resources for correct name pronunciation.MethodsWe developed a 60-minute interactive virtual workshop with didactics, small-group sharing of personal experiences, and case discussions. We used an anonymous postworkshop survey to evaluate workshop effectiveness.ResultsWe presented the workshop at one local academic conference and two local educational conferences to learners of all levels from medical students to faculty. We collected postworkshop survey results from 78 participants of diverse racial and ethnic backgrounds. Participants reported learning historical context, ways to ask about correct name pronunciation, correcting name mispronunciation, documenting pronunciation, and sources for applications to practice. The main barriers to implementing workshop lessons included personal and structural factors.DiscussionThis workshop effectively fills an educational gap by addressing the importance of correct name pronunciation in order to provide a more inclusive environment for clinicians and patients alike.

Project description:Potato (Solanum tuberosum) is the third most important food crop in the world. Although the potato genome has been fully sequenced, functional genomics research of potato lags relative to other major food crops due primarily to the lack of a model experimental potato line. Here, we present a diploid potato line, 'Jan', which possesses all essential characteristics for facile functional genomics studies. Jan has a high level of homozygosity after seven generations of self-pollination. Jan is vigorous and highly fertile with outstanding tuber traits, high regeneration rates, and excellent transformation efficiencies. We generated a chromosome-scale genome assembly for Jan, annotated genes, and identified syntelogs relative to the potato reference genome assembly DMv6.1 to facilitate functional genomics. To miniaturize plant architecture, we developed two "mini-Jan" lines with compact and dwarf plant stature using CRISPR/Cas9-mediated mutagenesis targeting the Dwarf and Erecta genes related to growth. Mini-Jan mutants are fully fertile and will permit higher-throughput studies in limited growth chamber and greenhouse space. Thus, Jan and mini-Jan provide an outstanding model system that can be leveraged for gene editing and functional genomics research in potato.

Project description:Difficulties in selectively attending to one among several speakers have mainly been associated with the distraction caused by ignored speech. Thus, in the current study, we investigated the neural processing of ignored speech in a two-competing-speaker paradigm. For this, we recorded the participant's brain activity using electroencephalography (EEG) to track the neural representation of the attended and ignored speech envelope. To provoke distraction, we occasionally embedded the participant's first name in the ignored speech stream. Retrospective reports as well as the presence of a P3 component in response to the name indicate that participants noticed the occurrence of their name. As predicted, the neural representation of the ignored speech envelope increased after the name was presented therein, suggesting that the name had attracted the participant's attention. Interestingly, in contrast to our hypothesis, the neural tracking of the attended speech envelope also increased after the name occurrence. On this account, we conclude that the name might not have primarily distracted the participants, at most for a brief duration, but that it alerted them to focus to their actual task. These observations remained robust even when the sound intensity of the ignored speech stream, and thus the sound intensity of the name, was attenuated.
