From research showing that adults in an Amazon village had about equal competence to Harvard students at basic geometry, Elizabeth Spelke drew a striking lesson.“Amazonian adults look like Harvard students, not like kids,” Spelke, a professor of psychology, told a packed room at the Barker Center Thursday night. “We learned that knowledge of Euclidian geometry can develop in the absence of schooling.”The surprising results from the study of Brazil’s Munduruku show that formal learning is not needed to develop navigational skills, said Spelke, director of the Laboratory for Developmental Studies.Spelke, whose lab is renowned for research into the development of language and other bedrock cognitive skills, focused in her talk on research into how animals and humans place themselves and navigate. The experiments involve spinning research subjects — whether humans or lab rats — until they lose their bearings, and studying how they reorient themselves in a spartan room.Infants and toddlers are adept at using geometric clues to orient themselves in three-dimensional space to find a hidden toy, but less so if their bearings have been disturbed. Lab rats had the same problem, and were unable to process complex decisions or to integrate more than one element. Somewhere along the development continuum, humans, whether at Harvard or in a village along the Amazon, develop the ability to integrate a second distinguishing characteristic — such as a wall painted a different color — to get their bearings. The function of navigation is innate to humans.The frontier is in understanding how it develops.“How does it become natural to us?” she asked.Spelke found no differences in navigational skills based on gender.“There are no sex differences,” she said. “People are really good at this. It’s something we do without being aware of it.”But with more dependence on computers and robots, our abilities might be at risk, she said, seizing on an audience member’s question about the effects of technology, such as smartphones, on child development.“I am worried we’re all going to be using GPSes all the time,” Spelke said. “The Mundurukus are better than Harvard students because they have to keep navigating all the time.”Drivers in modern societies rely heavily on GPS navigation. Looking at a map is almost old-fashioned.“I’m worried it will cause our systems to atrophy,” Spelke said.“We’re doing this enormous experiment on ourselves and our children and grandchildren,” she said. “Innate systems disappear if you don’t use them. It’s a real question of what’s going to happen with all this.”
Effective March 1, the Notre Dame Security Police Department will be renamed the Notre Dame Police Department, the University announced in a press release Thursday.With the name change, the department aims “to bring clarity for both the campus community and partners in law enforcement, more accurately portray the enforcement duties of the department and reinforce the department as a sworn police force,” according to the release. The department reached the decision after extensive research, which included meetings with groups on campus and at other institutions, the press release said.According to the release, the department will also be undergoing several operational changes to better distinguish police officers from other campus security workers. Only police officers will be responding to phone calls, and only officers will patrol the campus and drive police cars with sirens and light bars. Police officers will still wear navy blue shirts and pants, but outreach, engagement and safety inspection staff will now wear green shirts and khaki pants.“When someone calls the Notre Dame Police Department, they will be speaking with a police officer,” Notre Dame police chief Keri Kei Shibata said in the release. “And only our officers will respond to emergencies and patrol campus, so our students, visitors, faculty and staff will know what they can expect from the officer.” Outreach and community staff will spearhead crime prevention and community outreach programs, including training sessions for personal defense and sexual assault prevention. Safety and inspection staff will continue to perform routine inspections across campus. Tags: Campus Safety, NDSP, Notre Dame Security Police

New Delhi : Live Streaming Cricket, Australia vs Sri Lanka at Hotstar and Star Sports: Sri Lanka has chosen to bowl against Australia at the Kennington Oval in London. Suranga Lakmal is out while Nuwan Pradeep and Lasith Malinga are in. For Australia, Jason Behrendorff replaces Nathan Coulter-Nile. Aaron Finch blasted his 24th fifty but David Warner fell for 26 as Dhananjaya de Silva broke the 82-run stand for the opening wicket. Finch continued on his merry ways and shared a brilliant partnership with Steve Smith. The Australian skipper converted his fifty into a big one as he blasted his 14th century and first in the ICC Cricket World Cup 2019 to boost the five-time champions against the 1996 champions. Australia are currently third in the points table while Sri Lanka are fifth. Australia has lost only once against Sri Lanka and that was in the final of the 1996 World Cup. The 20th match of the ICC World Cup 2019 will feature Australia vs Sri Lanka locking horns with each other at The Oval in London on Saturday. It wouldn’t be wrong to say that Sri Lanka has been the unlukiest team in the ongoing ICC Cricket World Cup 2019 with two of their four games being washed out due to heavy rain. Sri Lanka started off their World Cup campaign with an obnoxious outing, suffering a 10-wicket loss against the current table toppers New Zealand. However, they came back strongly against Afghanistan to open their account in this mega event. Australia, led-by Aaron Finch are currently placed at number two position in points table and have won three out of four games in the competition so far.
