Babies cry in their native language

08.02.2010

A group of psychologists from the University of Würzburg (Germany) recorded the cry of 60 newborns from three to five days old from Germany and France. The recordings were then passed through a computer that produced a spectrogram of the sounds.

The resulting diagrams show that German infants start crying with high and loud notes, and then gradually reduce the frequency and volume. French, on the contrary, move from low frequency and volume to high.

The authors of the work attribute this to the fact that the child hears his native speech while in the womb, and imitates some features of pronunciation in his crying, even without being able to speak. It is known that the French raise their tone towards the end of the phrase, and their stress is always at the end of the word. In German, the stress is usually closer to the beginning of the word.

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, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Helping your child with homework is not helpful 19.08.2022

For decades, the scientific community has encouraged parental help and control over homework. Allegedly, the joint performance of school work has a positive effect not only on discipline, but also on the grades of children. Alas, American scientists in a new study dispelled this myth.

US scientists used two datasets covering students in grades 1-5 in public and private schools. When analyzing the results, the socioeconomic status and education of parents were also taken into account. The results were very surprising - no relationship was found between parents' help with homework and the child's success in math or reading.

Scientists have found that no matter how smart an adult or child is, whatever their socioeconomic status, and how much time is spent on textbooks, this is unlikely to have any significant impact on a child's academic results.

In earlier studies, scientists have already wondered what kind of help parents should provide with homework. And they came to the conclusion that with the right attitude and choice of the right strategy, adults are able to instill in a child a love of learning.

However, there are many factors that can hinder rather than help you succeed in school. For example, parents may perceive helping with homework as stressful, which can create some tension or pressure. Lack of time in adults can lead them to simply complete tasks on their own and give answers instead of explanations. But scientists see the main reason for the failure of such assistance in the fact that parents are simply not trained to convey information in the way that teachers do.

"Primary school is the growth of knowledge, but even more - the skills and habits of the child," scientists say.

The researchers note that although doing homework together will not affect academic performance, it may well have positive results in other aspects - for example, preventing a child's psychological health or increasing the amount of time spent together.
