Item Annotating Modernism: Marginalia and Pedagogy from Virginia Woolf to the Confessional Poets(Taylor & Francis, 2021) Goodspeed-Chadwick, Julie; IUPUC School of Liberal ArtsItem Associations between acoustic features of maternal speech and infants’ emotion regulation following a social stressor(Wiley, 2022-01) Kolacz, Jacek; daSilva, Elizabeth B.; Lewis, Gregory F.; Bertenthal, Bennett I.; Porges, Stephen W.; IUPUC Division of ScienceCaregiver voices may provide cues to mobilize or calm infants. This study examined whether maternal prosody predicted changes in infants’ biobehavioral state after the still face, a stressor in which the mother withdraws and reinstates social engagement. Ninety-four dyads participated in the study (infant age 4–8 months). Infants’ heart rate and respiratory sinus arrhythmia (measuring cardiac vagal tone) were derived from an electrocardiogram (ECG). Infants’ behavioral distress was measured by negative vocalizations, facial expressions, and gaze aversion. Mothers’ vocalizations were measured via a composite of spectral analysis and spectro-temporal modulation using a two-dimensional fast Fourier transformation of the audio spectrogram. High values on the maternal prosody composite were associated with decreases in infants’ heart rate (β = −.26, 95% CI: [−0.46, −0.05]) and behavioral distress (β = −.23, 95% CI: [−0.42, −0.03]), and increases in cardiac vagal tone in infants whose vagal tone was low during the stressor (1 SD below mean β = .39, 95% CI: [0.06, 0.73]). High infant heart rate predicted increases in the maternal prosody composite (β = .18, 95% CI: [0.03, 0.33]). These results suggest specific vocal acoustic features of speech that are relevant for regulating infants’ biobehavioral state and demonstrate mother–infant bi-directional dynamics.Item Associations between infant–mother physiological synchrony and 4- and 6-month-old infants’ emotion regulation(Wiley, 2021-09) Abney, Drew H.; daSilva, Elizabeth B.; Bertenthal, Bennet I.; IUPUC Division of ScienceIn this study we assessed whether physiological synchrony between infants and mothers contributes to infants’ emotion regulation following a mild social stressor. Infants between 4 and 6 months of age and their mothers were tested in the face-to-face-still-face paradigm and were assessed for behavioral and physiological self-regulation during and following the stressor. Physiological synchrony was calculated from a continuous measure of respiratory sinus arrhythmia (RSA) enabling us to cross-correlate the infants’ and mothers’ RSA responses. Without considering physiological synchrony, the evidence suggested that infants’ distress followed the prototypical pattern of increasing during the Still Face episode and then decreasing during the reunion episode. Once physiological synchrony was added to the model, we observed that infants’ emotion regulation improved if mother–infant synchrony was positive, but not if it was negative. This result was qualified further by whether or not infants suppressed their RSA response during the Still Face episode. In sum, these findings highlight how individual differences in infants’ physiological responses contribute significantly to their self-regulation abilities.Item Book Review—My Life with a Theory: John L. Holland’s Autobiography and Theory of Careers(NBCC, 2021-01) Carr, Darrin; IUPUC Division of ScienceItem Brief Report: Reduced Temporal-Central EEG Alpha Coherence During Joint Attention Perception in Adolescents with Autism Spectrum Disorder(Springer, 2016-04) Jaime, Mark; McMahon, Camilla M.; Davidson, Bridget C.; Newell, Lisa C.; Mundy, Peter C.; Henderson, Heather A.; Science, IUPUI ColumbusAlthough prior studies have demonstrated reduced resting state EEG coherence in adults with autism spectrum disorder (ASD), no studies have explored the nature of EEG coherence during joint attention. We examined the EEG coherence of the joint attention network in adolescents with and without ASD during congruent and incongruent joint attention perception and an eyes-open resting condition. Across conditions, adolescents with ASD showed reduced right hemisphere temporal-central alpha coherence compared to typically developing adolescents. Greater right temporal-central alpha coherence during joint attention was positively associated with social cognitive performance in typical development but not in ASD. These results suggest that, in addition to a resting state, EEG coherence during joint attention perception is reduced in ASD.Item Counseling Adolescents Aging Out of Foster Care: A Neglected and Underserved Population(2021) Tertocha-Ubelhor, Taylor; Russ, Brian R.; IUPUC Division of ScienceThe high prevalence of youth aging out of the foster care system and the numerous poor outcomes they experience during the transition to emerging adulthood has been well documented. Although addressing the complex needs and concerns of this distinct population can be difficult, mental health counselors maintain the philosophical tenants and training strengths necessary to successfully serve youth aging out of foster care. This article aims to provide counselors with the historical context, developmental framework, and specific challenges needed to better understand this population, as well as suggested counseling implications to address their unique needs by reviewing relevant literature.Item Current contributions to the systematics of Thraulodes Ulmer 1920 (Ephemeroptera: Leptophlebiidae)(Magnolia Press, 2021-12) Jacobus, Luke M.; IUPUC Division of ScienceItem The Dual Literary Biography of Sylvia Plath and Anne Sexton: A Review of Three-Martini Afternoons at the Ritz: The Rebellion of Sylvia Plath and Anne Sexton by Gail Crowther(Indiana University, 2021-10) Goodspeed-Chadwick, Julie; IUPUC School of Liberal ArtsThis book review provides an overview of the newest biography about Sylvia Plath and Anne Sexton.Item An EEG based Channel Optimized Classification Approach for Autism Spectrum Disorder(IEEE, 2019) Haputhanthri, Dilantha; Brihadiswaran, Gunavaran; Gunathilaka, Sahan; Meedeniya, Dulani; Jayawardena, Yasith; Jayarathna, Sampath; Jaime, Mark; IUPUC Division of ScienceAutism Spectrum Disorder (ASD) is a neurodevelopmental condition which affects a person's cognition and behaviour. It is a lifelong condition which cannot be cured completely using any intervention to date. However, early diagnosis and follow-up treatments have a major impact on autistic people. Unfortunately, the current diagnostic practices, which are subjective and behaviour dependent, delay the diagnosis at an early age and makes it harder to distinguish autism from other developmental disorders. Several works of literature explore the possible behaviour-independent measures to diagnose ASD. Abnormalities in EEG can be used as reliable biomarkers to diagnose ASD. This work presents a low-cost and straightforward diagnostic approach to classify ASD based on EEG signal processing and learning models. Possibilities to use a minimum number of EEG channels have been explored. Statistical features are extracted from noise filtered EEG data before and after Discrete Wavelet Transform. Relevant features and EEG channels were selected using correlation-based feature selection. Several learning models and feature vectors have been studied and possibilities to use the minimum number of EEG channels have also been explored. Using Random Forest and Correlation-based Feature Selection, an accuracy level of 93% was obtained.Item Ephemeroptera of Canada(ARPHA, 2019-01-24) Jacobus, Luke M.; IUPUIC Division of ScienceThus far, 335 currently valid species in 82 genera and 21 families of mayflies (Ephemeroptera) have been documented from Canada, remarkably representing a little more than half of the combined species richness of Canada, Mexico and the USA. The current known species richness for Canada represents an increase of 11.3% as compared to that reported in 1979. Species richness is greatest in the families Heptageniidae (83), Baetidae (76) and Ephemerellidae (45). A total of 328 DNA Barcode Index Numbers (BINs) are available for Canadian mayfly species. The greatest net gains anticipated for future species tallies are for Baetidae (25), Heptageniidae (10) and Leptophlebiidae (10). A total of 66 more species overall is anticipated for Canada, with greatest gains potentially coming from lentic habitats across Canada and from far eastern and far western areas in general. However, even metropolitan areas should not be overlooked for the potential of discovery.
