According to the findings of a new study from Queen’s University Belfast, narcissistic teens may show better results at school.
For the study, a lead researcher Kostas Papageorgiou and his colleagues recruited 340 teenage students from different high schools in Milan, Italy. Having assessed the received data, the scientists concluded that teens with higher levels of subclinical narcissism tend to be more mentally tough what leads to better performance at school.
Lead researchers Kostas Papageorgiou, a lecturer in developmental psychopathology at Queen’s University Belfast in the United Kingdom, says: “People who score high on subclinical narcissism may be at an advantage because their heightened sense of self-worth may mean they are motivated, assertive, and successful in certain contexts.”
A recent research from the US finds that people who go to bed and wake up early have a lower risk of developing depression.
A team of researchers analyzed the relevant medical data of 32,470 female participants who were aged 55 years on average. In 2009, at the start of the study, all participants were depression-free. In the course of the study, they reported changes in their health in questionnaires after 2 years.
Having analyzed the gathered data, the team concluded that early birds had a 12–27% lower risk of depression than other participants.
Lead study author Céline Vetter says: “Alternatively, when and how much light you get also influences chronotype, and light exposure also influences depression risk. Disentangling the contribution of light patterns and genetics on the link between chronotype and depression risk is an important next step.”
According to a new study, conducted by the researchers from Ohio State University, US, coffee is not only can help us more alert and focus but also can enhance interaction within a team. The study was published in the Journal of Psychopharmacology.
For the research, the scientists conducted two related experiments. For the first experiment, seventy-two undergraduate students were recruited. They were randomly split into groups of 5 persons. For the second experiment, the scientists recruited 61 participants.
Having analyzed the received data from both experiments, the researchers found that the volunteers who had drunk regular coffee before participation tended to talk more, but they were also more focused on their given topic of discussion and did not ramble as much as those who had not ingested caffeine.
A new study from Ohio State University, US, suggests that sociability, especially later in life, may bring many mental and physical health benefits — it can protect against cognitive decline.
For their research, the scientists included mice aged 15–18 months. As a part of an experiment, they were divided into two groups. One group was housed in pairs modeling “an old couple”. The other mice were placed into groups containing 6 rodents. They were given the conditions modeling housing condition for 3 months.
Having analyzed the received results, the scientists concluded that mice that were living in a group were better in remembering new locations and new things.
The researchers insist that it is important for people to make decisions about choosing a place to live when they get older, as these choices could either facilitate social activities or prevent individuals from maintaining a rich social life.
A recent study, which is considered to be the largest of its kind, suggests that a certain link exists between people who wear glasses (or contacts) and cognitive function. According to its findings, intelligent people are almost 30% more likely to wear glasses.
For the study, a team of scientists analyzed the genetic information of over 300,000 individuals from existing genomic databases where the participants provided samples for DNA analysis, answered questionnaires, and underwent tests designed to give a measure of their general cognitive ability.
Genetic statistician Gail Davis, a lead author of the study, of the University of Edinburgh in the UK, says: “This study, the largest genetic study of cognitive function, has identified many genetic differences that contribute to the heritability of thinking skills. The discovery of shared genetic effects on health outcomes and brain structure provides a foundation for exploring the mechanisms by which these differences influence thinking skills throughout a lifetime.”
