It’s time to face that we can’t pay attention to things, we don’t really want to do it

“I can’t do anything for more than fifteen minutes without looking at the mobile.” A while ago, in Xataka we published A very interesting report about how we had become an eternally decentralized generation. In it, a good number of testimonies and several experts talked about one of the common places of our time: the feeling that we are losing our ability to pay attention. But is it true? The question is not absurd, of course. Especially since the debate is not so much whether memory (attention or other cognitive abilities) changes with the use of mobile devices. Of course they change. They change functionally and do so at a structural level. As Manuel Sebastián explained to usResearcher at the Cerebral Cartography Unit of the Complutense University, “we know that the text that includes links (hypertext) seems to be remembered worse in general, which is totally logical because they constitute distractors and the role of attention is critical in memory” . However, as Sebastián reminded us, “the fact that information is processed differently is not necessarily bad.” The question is whether the changes are worse, if they are leaving us more helpless in the face of certain phenomena of the world. What about our attention? A few months ago, a team from the Faculty of Psychology of the University of Vienna this question was askedbut it is not something to answer. After all, to do so we need to be able to go beyond personal sensations and find attention measurements in numerous contexts, times and ages. Measurements, in addition, that they were not theoretical but were vinvulated to solve concrete problems. Where could they find such data? There was only one answer: in Intelligence tests. That huge tailor drawer that are intelligence tests. For decades, psychologists have been passing intelligence tests to millions of people and, thanks to this, we have a huge base of psychometric evaluations. Well, among that huge amount of data: there is attention tests. Once they realized this, the Researchers gathered 179 Studies with 287 independent samples from 32 different countries over 31 years: that is, they gathered evidence of more than 20,000 people and examined whether throughout these three decades a decay of attention was identified. The results are … counterintuitive. When they examined children, adolescents and young people, They realized that their scores remained stable over the years. When they examined adults, they found that, in fact, The scores improved. Yes, you have read well: our attention has been improving for years. So we are not losing attention capacity? As Adam Grant saidProfessor of Organizational Psychology at Wharton, the problem has never been attention, it is motivation. If we want to use our attention we have the ability to do it, the problem is that we usually do not want. We are so surrounded by interesting and attractive things that we end up letting us fall into multitasking. And, of course, that has consequences. In fact, it is likely that these consequences are the most notice and those that produce the feeling that we are losing the ability to pay attention. Come on, we are “cheating” ourselves. For example, we know that “pay attention” to various media at the same time (watch a movie while we consult the mobile) It has a negative effect on memory. That is, we remember worse what we see while we do other things. The fact is that when we begin to remember the movies worse, we attribute it to our attention and not to the way we saw the movie. Everything is confused. And you have to be careful with that, because if we do not start from reality, it will be impossible Dominate again Our attention capacity.

The “hypercarnivore” that lived 30 million years ago and today focuses the attention of paleontologists

The Egyptian paleontologist Shorouq al-Ashqar and her team were about to conclude their work in the archaeological site where they worked when they noticed something that caught their attention. As explained by Al-Ashqar, it was teeth of considerable size that stood out from the rock. Bastetodon Syrtos. The teeth belonged to the fossilized skull of a mammal of about 30 million years old and belonging to a species so far unknown. The team responsible for the finding has cataloged the new species He has given him a name: Bastetodon Syrtos. The “almost complete” skull found has allowed the team to obtain valuable information about This new species. For example, let’s heal the animal would have had a size similar to that of modern leopards. B. Syrtos would have belonged to the order of the hyitodontes (Hyaenodonta), an already extinct group of mammals related to that of carnivores (Carnivora), The group in which there are species present such as cats and hyenas. The name Hyaenodonta It makes reference to these animals since, despite not having a direct relationship, the shape of the teeth of the extinct order is similar to that of the teeth of the modern species. Hypercarnivorous diet. The skull It has even served to get an idea of ​​what this animal ate. The team indicates that B. SyrtosIt would have been what we know as a “hypercarnivore” (this time in a non-taxonomic but strictly food sense), an animal whose diet would have consisted of at least 70% of meat. This species would have been, their discoverers believe, on the cusp of the “food pyramid” in its ecosystem. The team presented its finding Through an article In the magazine Journal of Vertebrate Paleontology. Etymology of a name. The choice of name is a wink in the history of the country in which it has been discovered. The Egyptian goddess Bastet embodied, Explain the teamprotection, pleasure and good health. Bastet was represented well as a cat well as an anthropomorphic figure with a feline head, similar to that that members of the newly discovered species could have had. “-Oode,” on the other hand, it is a usual suffix in zoology that means “tooth.” The fayum. Thanks to its oasis, the fayum is one of the few areas where the water dyes green the land beyond the Nile Valley, which makes it a key region for agriculture in Egypt. But there is another characteristic that makes this environment interesting: its deposits, both archaeological and paleontolocic. The new finding, in fact, has served to give context to some remains found in the region 120 years ago. From the skull found and fossils discovered in 1904 in the region belonging to hyitodars of a size even larger than that of B. Syrtos. They classify these remains into a different genre to what they have called Sekhmetops. Bastetodon and Sekhmetops. Until now these animals (whose new name also refers to an Egyptian god, Sekhmet) had been classified in the same group as European hyenodontes. The new classification places the origin of the two new genres, Bastetodonand Sekhmetopsin the African continent itself. According to the new study, these two genres would have expanded in successive waves from Africa to the adjacent continents and even to North America.
