To determine whether the past half-year of COVID-19-related lockdowns, stay-at-home orders, and social isolation were associated with changes in high-risk alcohol use, a total 5,931 individuals completed Alcohol Use Disorders Identification Test (AUDIT) at one six time points from April through September 2020. Over 6-month period, hazardous use likely dependence increased month-by-month for those under lockdowns compared to not restrictions. This increase harmful related behaviors is have...
Artificial language learning studies have demonstrated that learners exposed to many different nonword combinations representing a grammatical form demonstrate rapid of without explicit instruction. However, presented with few exemplars, even when they are repeated frequently, fail learn the underlying grammar. This study translated this experimental finding in therapeutic context.Eighteen preschool children impairment received conversational recast treatment for morpheme errors. Over 6-week...
Background: By March 2020, the World Health Organization declared COVID-19 crisis as a worldwide pandemic and many local governments instituted stay-at-home orders closed non-essential businesses. Within United States, tens of millions workers lost their jobs financial security during first few weeks national response, in an attempt to slow global pandemic. Because enormity its potential impact on mental health, objective present study was document prevalence health problems association with...
To combat the spread of COVID-19, many communities implemented restrictions on personal movement, often referred to as "lockdowns." We hypothesized that continued lockdowns might be associated with increased feelings aggression.Over first six months COVID-19 pandemic, Buss-Perry Aggression Questionnaire (BPAQ) was administered a total 5,928 adults distributed proportionally from across United States during independent online cross-sectional surveys collected each month. Data 6-month period...
The U.S. vaccine campaign against COVID-19 began in December 2020, but many individuals seem reluctant to get vaccinated. During the first week of vaccination campaign, we collected data from 1017 with an online survey identify factors that were associated willingness once it is available. Most participants (55.3%) willing vaccine, although 46.2% also expressed some fear vaccine. Political ideology was by far most consistent predictor both be vaccinated and followed participant sex,...
Even without explicit instruction, learners are able to extract information about the form of a language simply by attending input that reflects underlying grammar. In this study, authors explored role variability in learning asking whether varying number unique exemplars heard learner affects an artificial syntactic form.
Acute exposure to light within the blue wavelengths has been shown enhance alertness and vigilance, lead improved speed on reaction time tasks, possibly due activation of noradrenergic system. It remains unclear, however, whether effects extend beyond simple processes also other aspects cognition, such as memory performance. The aim this study was investigate a thirty minute pulse versus placebo (amber light) in healthy normally rested individuals morning during verbal consolidation (i.e.,...
Background. Mild traumatic brain injuries (mTBIs) are a significant social, sport, and military health issue. In spite of advances in the clinical management these injuries, underlying pathophysiology is not well-understood. There critical need to advance objective biomarkers, allowing identification tracking long-term evolution changes resulting from mTBI. Diffusion-weighted imaging (DWI) allows for assessment white-matter properties shows promise as suitable biomarker mTBI pathophysiology....
Objective: Identify the treatment effects of 6 weeks daily 30-minute sessions morning blue light therapy compared with placebo amber in sleep disruption following mild traumatic brain injury. Design: Placebo-controlled randomized trial. Participants: Adults aged 18 to 45 years a injury within past months ( n = 35). Main Outcome Measures: Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, Beck Depression Inventory II, Rivermead Post-concussion Symptom Questionnaire, Functional Outcomes...
Introduction Emotional intelligence (EI) is associated with a range of positive health, wellbeing, and behavioral outcomes. The present article describes the development validation an online training program for increasing EI abilities in adults. was based on theoretical models emotional functioning empirical literature successful approaches socioemotional skills resilience. Methods After initial design, programming, refinement process, completed tested efficacy sample 326 participants (72%...
Socioemotional skills, such as the ability to recognize, understand, and regulate emotions of self others, are associated with both physical emotional health. The present study tested effectiveness a recently validated online training program for increasing these skills in adults. In this study, 448 participants (323 female) were randomly assigned complete or placebo control program. Among those who completed (
Mild traumatic brain injury (mTBI) remains the most commonly reported head in United States, and is associated with a wide range of post-concussive symptoms including physical, cognitive, affective impairments. Elevated aggression has been documented mTBI; however, neural mechanisms at chronic stage recovery remain poorly understood. In present study, we investigated association between white matter integrity mTBI using diffusion tensor imaging (DTI). Twenty-six age-matched adults...
Despite extensive research in the field of aging neuroscience, it still remains unclear whether age related cortical changes can be detected different functional networks younger adults and these respond identically to healthy aging. We collected high-resolution brain anatomical data from fifty-six young (mean = 30.8±8.1 years, 29 males). performed whole parcellation into seven networks, including visual, somatomotor, dorsal attention, ventral limbic, frontoparietal default mode estimated...
Background: Mild traumatic brain injuries (mTBIs) are associated with novel or worsened sleep disruption. Several studies indicate that daily morning blue light therapy (BLT) is effective for reducing post-mTBI daytime sleepiness and fatigue. Studies demonstrating changes in structure function following BLT limited. The present study's purpose to identify the effect of on functional connectivity association between these self-reported change sleepiness. Methods: A total 62 individuals...
Insomnia is often accompanied by excessive pre-sleep rumination. Such ruminative thinking also associated with increased connectivity of the default mode network (DMN). It likely that DMN and rumination contribute to pathogenesis insomnia. We hypothesized resting state functional (rsFC) between other brain regions prior bedtime would predict objectively measured sleep among individuals Twenty participants (12 female; M age = 26.9, SD 6.6 years) symptoms insomnia underwent an rsFC scan in...
Mild traumatic brain injury (mTBI) is a common and often inconspicuous wound that frequently associated with chronic low-grade symptoms cognitive dysfunction. Previous evidence suggests daily blue-wavelength light therapy may be effective at reducing fatigue improving sleep in patients recovering from mTBI. However, the effects of on structure remain unexplored. In this study, we analyzed white-matter diffusion properties, including generalized fractional anisotropy, quantity water isotropic...
Blue wavelength light has been used successfully as a treatment method for certain mood disorders, but, the underlying mechanisms behind enhancing effects of remain poorly understood. We investigated single dose 30 min blue ( n = 17) vs. amber 12) exposure in sample healthy adults on subsequent resting-state functional and directed connectivity, associations with changes state affect. Individuals who received showed greater positive connectivity between right amygdala region within left...
