Portable devices harm the development of speech

15.05.2017

Dr. Catherine Birken of The Hospital for Sick Children (SickKids) and Julia Ma of the University of Toronto conducted a study on the impact of portable devices - smartphones, tablets, electronic games and more - on children from 6 to 24 months. According to the results of the work, these children may have a higher risk of delayed expressive speech.

The study involved 894 children aged 6 months to 2 years. Over 18 months, according to parental data, 20 percent of children used handheld devices daily, averaging 28 minutes. Based on readings from the Speech Delay Tool, the researchers found that the more time a child spent on the gadget, the more likely the child was to have speech delays.

For every additional 30 minutes that a portable device was on, the risk of delay increased by 49 percent. However, there was no obvious association between screen time and delays in social interactions, development of gestures and body language, etc.

“Handheld devices are ubiquitous these days,” said Dr. Birken. “While the new pediatric guidelines suggest limiting screen time for infants and toddlers, we believe smartphone and tablet use with young children has become fairly common. This is the first study , reporting an association between handheld device time and an increased risk of delaying the development of expressive speech"

More research is needed to understand the type and content of screen activities that children engage in, to further explore the mechanisms underlying the apparent association between screen time and speech delays, such as time spent with parents on handheld devices, and to understand how it influences the deep and long-term outcomes of early childhood communication development.

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, ... >>

XNUMXD water vapor screen 18.04.2014

Scientists and engineers at the University of Bristol have developed an original desktop display that uses water mist instead of a screen. The display is capable of displaying XNUMXD shapes and could change the way humans and computers interact.

The resolution of the "fog screen" is not high, but it has great potential and is still easier to implement and use than immersive virtual reality technologies.

The new screen is a suspension of tiny drops of water in the air, onto which a three-dimensional or flat image is projected using a projector. Users can not only look at the picture, but also rotate it, drag it, "pass" it to each other with simple hand movements. The screen allows you to display two-dimensional images, while the absence of obstacles for hands facilitates interaction with the picture.

The table itself is a simple structure, consisting of a fog machine (water tank and fans), a projection screen, video cameras and projectors that create a kind of interactive whiteboard on the surface of the table. This board demonstrates two-dimensional images that can be "pulled out" from the screen and "hung" in the air - that is, use the projection on the water mist.

The developers note that their screen facilitates the collaboration of several people who have to exchange various data in the form of tables and three-dimensional images. Users can see each other's activities and quickly communicate the necessary information. Switching between individual and group work is also significantly accelerated. Such opportunities can be useful to the military or employees of emergency response headquarters.

The new desktop display will be presented at the end of April at the international conference ACM CHI 2014.
