    Abstract The aim of this study was to discover the effects of COVID-19 on the mental health, academic life, social life of students and discover their interrelationships at a boarding school in New Jersey, USA. A majority of participants reported that COVID-19 had a negative effect on their mental health and social lives, felt well informed about COVID-19 cases on campus, and were unconcerned about getting COVID-19 at school. Given the correlations and differences observed, it is likely that some groups of adolescents may be at greater risk of impacted mental health as a result of the COVID-19 pandemic. .

    Abstract This study aimed to determine the prevalence of and associations between anxiety, social isolation, and loneliness in a sample of older adults in Northern California during the stay-at-home order enacted during the COVID-19 pandemic. 514 older adults completed a 24-item survey. Perceived isolation and loneliness were reported in 56.4% and 36.0% of participants, respectively. Loneliness was found to be associated with both social isolation and COVID-19-related anxiety; however, social isolation and coronavirus-related anxiety were unrelated. Healthcare providers, social service providers, and families are encouraged to maintain or increase contact with older adults during the COVID-19 pandemic.

    Abstract Purpose Evidence-based data analysis methods are important in clinical research fields, including speech-language pathology and audiology. Although commonly used, null hypothesis significance testing (NHST) has several limitations with regard to the conclusions that can be drawn from results, particularly nonsignificant findings. Bayes factors (BFs) can be used to complement NHST and quantify the strength of evidence in favor of 1 hypothesis over another, given the data: commonly, either the alternate hypothesis over the null or the null hypothesis over the alternate. This article provides an introduction to BFs through JASP, a free, open-source, graphics-based statistics package that allows researchers to easily conduct both NHST and Bayesian analyses in a clear and reproducible manner. Method and Results Both traditional NHST analyses and Bayesian equivalents for correlations,

    Abstract Cognitive control warrants efficient task performance in dynamic and changing environments through adjustments in executive attention, stimulus and response selection. The well-known P300 component of the human event-related potential (ERP) has long been proposed to index "context-updating"-critical for cognitive control-in simple target detection tasks. However, task switching ERP studies have revealed both target P3 (300-350 ms) and later sustained P3-like potentials (400-1,200 ms) to first targets ensuing transition cues, although it remains unclear whether these target P3-like potentials also reflect context updating operations. To address this question, we applied novel single-trial EEG analyses-residue iteration decomposition (RIDE)-in order to disentangle target P3 sub-components in a sample of 22 young adults while they either repeated or switched (updated) task rules. The rationale was to revise the context updating hypothesis of P300 elicitation in the light of new evidence suggesting that "the context" consists of not only the sensory units of stimulation, but also associated motor units, and intermediate low- and high-order sensorimotor units, all of which may need to be dynamically updated on a trial by trial basis. The results showed functionally distinct target P3-like potentials in stimulus-locked, response-locked, and intermediate RIDE component clusters overlying parietal and frontal regions, implying multiple functionally distinct, though temporarily overlapping context updating operations. These findings support a reformulated version of the context updating hypothesis, and reveal a rich family of distinct target P3-like sub-components during the reactive control of target detection in task-switching, plausibly indexing the complex and dynamic workings of frontoparietal cortical networks subserving cognitive control.
