Anxiety is transmitted through the eyes

06.06.2016

Psychologists from Uppsala University and Washington University in St. Louis have found that the transmission of anxiety can occur through the eyes. Experiments were performed with infants 6 and 9 months old - they were shown a black circle of different diameters on a white background. The circle imitated the pupil, wide or narrow, and so, as it turned out, if the child was shown a wide "pupil", then his pupils dilated in response. For comparison, a black square was used, but children's pupils did not react to it.

It is known that the pupils react to an emotional state: fear, anxiety, in general, any emotional arousal makes them dilate. Of course, a circle on a white background is still not a real pupil, but it was important for the researchers to be able to accurately control the diameter of the pupil, which is why they chose such a surrogate. And, of course, it’s hardly worth talking about anxiety here either: on the one hand, as we said, the pupils dilate to any emotional arousal, on the other hand, the researchers were interested in the response itself, that is, whether the pupils of children can copy (even if not real).

However, stress can indeed be contagious. Sarah Waters and her colleagues at New York University and the University of California at San Francisco set the following experiment: women who had children of 12 and 14 months were subjected to stress - of course, with their consent.

The stressful situation was organized as usual: they were asked to make a report in front of the audience, which then had to evaluate the speaker, and the ratings could be either negative, or neutral, or positive. Then, after some time, the mothers returned to the children - and, as it turned out, plunged them into anxiety: the children's heart rate increased, other physiological indicators of stress appeared, and they began to avoid strangers. But those babies whose mothers did not go through a stressful test perceived strangers more calmly and did not become infected with any stress.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

The danger of carbonated drinks 28.09.2020

According to researchers from the University of Alabama at Birmingham, sugary soft drinks can also be a predictor of aggressive behavior in adolescents aged 11-13 years.

Sweet carbonated drinks, according to scientists, not only arouse aggression in teenagers, but also lead to the fact that by the age of 16 they begin to increase their consumption. So, we can talk about addiction.

Experts note that in order to reduce aggression in the behavior of adolescents, it is necessary to reduce the amount of carbonated drinks. At the same time, researchers do not exclude that reducing the number of such drinks can lead to depression.

Earlier studies have already confirmed the relationship between aggressiveness and mental problems in adolescents. It was among these children that cases of increased hyperactivity, depression, and suicidal tendencies were more common.
