McIntosh described the northern prominence as a “hedgerow in the solar plasma", which does appear exactly at the same spot around the sun’s polar crown every 11 years. Over this period, things like solar radiation, ejection of solar material, sunspots, and solar flares fluctuate. ![]() Solar cycles are periodic 11-year changes in the Sun’s activity. Scott McIntosh, a solar physicist and deputy director at the National Center for Atmospheric Research in Boulder, Colorado, told that he has never seen a vortex like this but notes that something odd usually happens at the sun's 55 degree latitudes once every solar cycle. Prominences consist of hydrogen and helium, and usually erupt when a structure becomes unstable and bursts outward, releasing the plasma. According to NASA, solar prominence is a large bright feature that extends outward from the Sun's surface. In a commentary that will accompany the article, University of Tennessee at Knoxville psychologist Lowell Gaertner, PhD, and his colleagues argue that simply looking at surface differences among cultures - what they call the phenotype - does little to advance the understanding of universal human behavior or genotype.The find is just the latest in a series of interesting space observations thanks to the capabilities of the James Webb Space Telescope. To address the problem, Heine and his colleagues suggest that journal editors and funding agencies encourage researchers to discuss the limitations of their samples and seek more representative study participants. “We hope that researchers will come to realize just how precarious a position we’re in when we’re trying to construct universal theories from a narrow, and unusual, slice of the population,” says Heine. ![]() He and his colleagues use many examples to demonstrate that studies that rely on a narrow swath of the world’s population need to be careful in assuming, as many do, that their results are universally applicable to the human species. If such seemingly basic processes as visual perception can differ across cultures, says Henrich, it makes sense that others do, too. In fact, people from some cultures were completely unaffected by certain illusions. college students perceive some visual illusions to a much greater degree than people from many other cultures, including the San foragers of the Kalahari. In one illustrative study from the 1966 book “The Influence of Culture on Visual Perception,” researchers found that U.S. ![]() They found that people from Western, educated, industrialized, rich and democratic (WEIRD) societies - who represent as much as 80 percent of study participants, but only 12 percent of the world’s population - are not only unrepresentative of humans as a species, but on many measures they’re outliers. ![]() In a forthcoming issue of Brain and Behavioral Sciences, anthropologist Joe Henrich, PhD, and psychologists Steven Heine, PhD, and Ara Norenzayan, PhD, review the available database of comparative social and behavioral science studies. The over-sampling of American college students may be skewing our understanding of human behavior, finds an analysis by researchers from the University of British Columbia. ![]()
