We are afraid of snakes and spiders from birth

26.10.2017

Even small children, who know almost nothing about the world around them, react nervously to pictures of snakes and spiders.

Very, very many of us are afraid of snakes and spiders - albeit not to the point of immediate fainting, but still. However, where does arachnophobia with ophidiophobia (or fear of snakes) come from? Someone believes that we learn to be afraid of spiders and snakes while we grow up, that is, these fears are acquired. Someone, on the contrary, believes that both are innate features of the psyche. On the one hand, it seems that everything is quite simple to find out here: you need to analyze when ophidiophobia and arachnophobia manifest themselves in the process of growing up.

And such experiments were repeatedly carried out: the children were shown images, among which there were pictures with spiders and snakes, and they watched the reaction. If a child noticed a dangerous object faster than something peaceful and harmless, it means that a mental program is already working in him, instructing him to be afraid of these creatures. But such studies usually involve quite large children, so that doubt inevitably arises whether the fear of snakes and spiders is really innate in them, or whether they have already learned it.

Psychologists from the Max Planck Institute for Human Brain and Cognitive Research, the University of Vienna and the University of Uppsala have found a way to solve this mystery. And they solved it simply - with the help of six-month-old babies. At this age, you should not expect from a child that he managed to learn something about spiders and snakes - he has not yet learned the world around him so well. Children were shown pictures of spiders or flowers in one version, or snakes or fish in another, and psychological reactions to the picture were assessed by changes in pupil size. Pupils are known to dilate when aroused, when we experience strong emotions and stress. At pictures of spiders and snakes, children's pupils noticeably dilated; in other words, even very young children can be worried about snakes and spiders.

At the same time, it is known from earlier studies that young children are not afraid of bears, rhinos, or any other potentially dangerous animals. Apparently, the fear of snakes and spiders is "sewn" into our brains by evolution. Obviously, the whole point is that once upon a time the ancestors of people for a very long time lived side by side with such snakes and spiders, which were really worth fearing. As for the larger predators, compared to snakes and spiders, they probably did not annoy the ancient great apes so much and not for so long.

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, ... >>

Controlling waves in a magnet using superconductors 04.11.2023

Research into the interaction of superconductors with magnets, conducted by Dutch physicists, opens up prospects for effective control of spin waves, which could become an alternative to existing technologies in the field of electronics. For many years, scientists have been looking for methods to effectively control spin waves, and new results confirm the possibility of controlling them at the micro level using superconductors.

The theory suggests that metal electrodes could provide control over spin waves, but such effects have been rare in experiments until now. TU Delft researcher Toeno van der Sar highlights that their research team has achieved a breakthrough by achieving complete control of spin waves using a superconducting electrode.

The magnetic field created by the spin wave interacts with the superconductor, which in turn acts as a mirror, reflecting the magnetic field and making it easier to control the up and down motion of the spin wave. It is important to note that changing the temperature of the superconducting electrode can fine-tune the magnitude of these changes in the spin waves.

To test their hypothesis, the scientists used a thin magnetic layer of yttrium iron garnet (YIG), a superconducting electrode, and another to excite spin waves. Cooling the device to -268 degrees led to the transition of the electrode to a superconducting state. The gradual slowing down of spin waves as they cool allowed scientists to study the properties of superconductors and spin waves in more detail.

Toeno van der Sar highlights the promise of spin-wave devices and superconductors that generate low heat and can generate light waves. It presents the possibility of using spintronic versions of frequency filters, resonators and other components in electronic devices, including cell phones, transistors and quantum computer elements.
