Then, in random order, they repeatedly showed them pictures of either a lion or an impala in a matrix of other distractor images and asked them to find the target animal.<\/p>\n<p>\u2018Following exposure to people yawning, participants were faster at detecting lions and slower in their search of impala,\u2019 said the researchers.<\/p>\n<p>A previous study by the same university found that seeing people yawn increased people\u2019s ability to detect snakes.<\/p>\n<p>By replicating the study with a different animal, the team were able to show that the effect was not just specific to snakes, but across different contexts.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/i.dailymail.co.uk\/1s\/2023\/09\/19\/22\/71701345-12537693-Studies_suggest_that_people_who_do_not_yawn_when_they_see_someon-a-125_1695159521198.jpg\" height=\"400\" width=\"634\"><\/p>\n<p>A previous study by the same university found that seeing people yawn increased people\u2019s ability to detect snakes\u00a0<\/p>\n<p>Dr Andrew Gallup, who was involved in both studies, said: \u2018Replications are important to ensure that the original findings were not spurious or due to some chance events or statistical anomalies.<\/p>\n<p>\u2018When we are able to replicate previous experiments, as we have done here, we gain confidence that the findings represent true effects.<\/p>\n<p>\u2018In this case, we also wanted to replicate the previous study to ensure that the effects observed in the original study were not due to the specific type of stimulus used (i.e., snakes).<\/p>\n<p>\u2018By performing a conceptual replication, we show that seeing other people yawn enhances threat detection, i.e., it improves vigilance, across different contexts.\u2019<\/p>\n<p>Source: <a href=\"https:\/\/www.dailymail.co.uk\/sciencetech\/article-12537693\/yawn-suny-polytechnic-institute-science-news.html\" target=\"_blank\" rel=\"noopener\">Read Full Article<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Yawns could help keep us safe by making people nearby more vigilant to threats when someone is tired Researchers found seeing someone yawn makes people more vigilant to threats\u00a0 Previous study found seeing yawns increased people\u2019s ability to detect snakes.
