Many natural events generate both visual and auditory signals, and humans are remarkably adept at integrating information from those sources. However, individuals appear to differ markedly in their ability or propensity to combine what they hear with what they see. Individual differences in audiovisual integration have been established using a range of materials, including speech stimuli (seeing and hearing a talker) and simpler audiovisual stimuli (seeing flashes of light combined with tones).

Mice produce ultrasonic vocalizations (USVs) at different ages and social contexts, including maternal-pup separation, social play in juveniles, social interactions, and mating in adults. The USVs' recording can be used as an index of sensory detection, internal state, and social motivation. While sensory deprivation may alter USVs' emission and some social behaviors in deaf and anosmic rodents, little is known about the effects of visual deprivation in rodents.

Article Synopsis
  • - This study highlights a new method of using cobalt silylene (Co=Si bond) for catalysis, which helps in group-transfer reactions.
  • - The setup offers two different sites (Co and Si) for activating substrates, which makes the process more versatile and efficient.
  • - By having these distinct reaction sites, the method prevents issues where competing substrates could deactivate the catalyst, allowing for smoother nitrene-group transfer to carbon monoxide.

Chronic hepatitis C infection is a major cause of liver cancer in the United States. Hawai'i's incidence of liver cancer consistently ranks among the highest in the US, due in part to the high prevalence of hepatitis B in the state. To better understand the factors associated with liver cancer among patients in Hawai'i with hepatitis C virus (HCV) infection, the patient database of Kaiser Permanente's Hawai'i region was used to identify a cohort of 3198 patients with a history of chronic HCV infection, of whom 159 (5%) were diagnosed with liver cancer between the years 2004-2020.

Revisiting the target-masker linguistic similarity hypothesis.

Atten Percept Psychophys

July 2022

Carleton College, Department of Psychology, One North College St, Northfield, MN, 55057, USA.

The linguistic similarity hypothesis states that it is more difficult to segregate target and masker speech when they are linguistically similar. For example, recognition of English target speech should be more impaired by the presence of Dutch masking speech than Mandarin masking speech because Dutch and English are more linguistically similar than Mandarin and English. Across four experiments, English target speech was consistently recognized more poorly when presented in English masking speech than in silence, speech-shaped noise, or an unintelligible masker (i.

Dominant species often have disproportionately high abundance in restored communities compared to native remnants, which potentially could reduce the conservation value of restorations. Research is needed to determine how the abundance of dominant species in restoration plantings affects community assembly, species diversity, and ecosystem function. Most studies of dominant species in grasslands were modeled after experiments on keystone species, using the short-term experimental removal of dominants to test their functional role in ecosystems.

St. Croix Watershed Research Station, Science Museum of Minnesota, Marine on St. Croix, Minnesota, United States of America.

The microbial communities of lake sediments have the potential to serve as valuable bioindicators and integrators of watershed land-use and water quality; however, the relative sensitivity of these communities to physio-chemical and geographical parameters must be demonstrated at taxonomic resolutions that are feasible by current sequencing and bioinformatic approaches. The geologically diverse and lake-rich state of Minnesota (USA) is uniquely situated to address this potential because of its variability in ecological region, lake type, and watershed land-use. In this study, we selected twenty lakes with varying physio-chemical properties across four ecological regions of Minnesota.

Hampshire College, 893 West St., Amherst, MA 01002, USA; Mount Holyoke, 50 College St., South Hadley, MA 01075, USA. Electronic address:

The P3 component (P300, P3b) is considered to be an effective index of attention and categorization processes when elicited in a visual oddball task, specifically reflecting the selection of a rare target item among frequent non-targets. Researchers have proposed that target categorization is guided by representations of target features held in working memory (WM), thus guiding attention and categorization processes to distinguish targets from non-targets. Although WM is theorized to have visuospatial, verbal and executive function components, most studies do not investigate how these WM components contribute to the P3.

Vax attacks: How conspiracy theory belief undermines vaccine support.

Prog Mol Biol Transl Sci

February 2022

Stony Brook University, Department of Political Science, Stony Brook, NY, United States.

As the world continues to respond to the spread of a novel coronavirus (SARS-CoV-2, which causes the disease commonly known as COVID-19), it has become clear that one of the most effective strategies for curbing the pandemic is the COVID-19 vaccine. However, a major challenge that health organizations face when advocating for the uptake of the COVID-19 vaccine is the spread of related misinformation and conspiracy theories. This study examines factors that influence vaccine hesitancy using two online survey samples, one convenience and one nationally representative, collected in the early summer of 2020 during the height of the second peak of coronavirus cases in the United States.

Hox transcription factors are conserved regulators of neuronal subtype specification on the anteroposterior axis in animals, with disruption of Hox gene expression leading to homeotic transformations of neuronal identities. We have taken advantage of an unusual mutation in the Caenorhabditis elegans Hox gene lin-39, lin-39(ccc16), which transforms neuronal fates in the C. elegans male ventral nerve cord in a manner that depends on a second Hox gene, mab-5.

Predation, combat, and the slings and arrows of an abrasive and high impact environment, represent just some of the biotic and abiotic stressors that fishes are armored against. The Pacific Spiny Lumpsucker (Eumicrotremus orbis) found in the subtidal of the Northern Pacific Ocean is a rotund fish covered with epidermal, cone-shaped, enamel odontodes. The Lumpsucker is a poor swimmer in the wave swept rocky intertidal, and this armor may be a lightweight solution to the problem of collisions with abiotic obstacles.

Musical expertise improves the precision of timing perception and performance - but is this expertise generic, or is it tied to the specific style(s) and genre(s) of one's musical training? We asked expert musicians from three musical genres (folk, jazz, and EDM/hip-hop) to align click tracks and tap in synchrony with genre-specific and genre-neutral sound stimuli to determine the perceptual center ("P-center") and variability ("beat bin") for each group of experts. We had three stimulus categories - Organic, Electronic, and Neutral sounds - each of which had a 2 × 2 design of the acoustic factors Attack (fast/slow) and Duration (short/long). We found significant effects of Genre expertise, and a significant interaction for both P-center and P-center variability: folk and jazz musicians synchronize to sounds typical of folk and jazz in a different manner than the EDM/hip-hop producers.

: Behavioral models suggest that strong tension-reduction alcohol-outcome expectancies (TREs) among drinkers should be associated with greater tension reduction after drinking. Yet, the few studies investigating this have found either no relationship or the opposite relationship.: We sought to explore this relationship by building upon the limitations of past studies and employing a placebo-controlled, within-subject experimental design.

To conserve wide-ranging species in human-modified landscapes, it is essential to understand how animals selectively use or avoid cultivated areas. Use of agriculture leads to human-wildlife conflict, but evidence suggests that individuals may differ in their tendency to be involved in conflict. This is particularly relevant to wild elephant populations.

The Significant Interest view entails that even if there were no medical reasons to have access to genetic knowledge, there would still be reason(s) for prospective parents to use an identity-release donor as opposed to an anonymous donor. This view does not depend on either the idea that genetic knowledge is profoundly prudentially important or that donor-conceived people have a right to genetic knowledge. Rather, it turns on general claims about (1) parents' obligations to help promote their children's well-being and (2) the connection between a person's well-being and the satisfaction of what I call their "worthwhile significant subjective interests.

"American Indian" as a Racial Category in Public Health: Implications for Communities and Practice.

Am J Public Health

November 2021

Danielle R. Gartner (Sault Ste. Marie Tribe of Chippewa Indians) is with the Department of Epidemiology & Biostatistics, College of Human Medicine, Michigan State University, East Lansing. Rachel E. Wilbur (Tolowa descent and Chetco descent) is with the Department of Anthropology, College of Arts & Sciences, and the Carolina Population Center, University of North Carolina, Chapel Hill. Meredith L. McCoy (Turtle Mountain Band of Chippewa Indians descent) is with the Department of American Studies and the Department of History, Carleton College, Northfield, MN.

When public health considers the health and disease status of Indigenous people, it often does so using a racial lens. In recent decades, public health researchers have begun to acknowledge that commonly employed racial categories represent history, power dynamics, embodiment, and legacies of discrimination and racism, rather than innate biology. Even so, public health has not yet fully embraced an understanding of other components of identity formation for Indigenous people, including political status within Native nations.
