Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Adults evaluate children according to words 29.02.2016

Often in a conversation about children, you can hear that some boy or girl has a smart face or smart eyes (well, or not smart, but vice versa). On the other hand, it is just as common to hear that someone's son or daughter is developed beyond his years. But how do we assess how developed a child is? It seems self-evident that adults evaluate children by their appearance, by facial expressions: after all, children are not adults, and they cannot yet express their personality in words and deeds. However, in reality, appearance is not the main thing, and we believe more in what the child says than in how he looks.

Psychologists from Florida Atlantic University set up an experiment in which adults were shown several photographs of six-year-old children, boys and girls. Some photos were artificially "grown up" - so that the child looked not at 6, but at 8-10 years old, while other photos, on the contrary, underwent "rejuvenation" - the children looked 4-5 years old. The photographs were accompanied by children's thoughts-statements, which were supposed to help adults determine the psychological portrait of the child. For example, the phrase "the sun won't come out tomorrow because it's (at something) angry" obviously spoke of the immaturity, "childishness" of a child who still lives to a very large extent in his fantasies. That is, the descriptions indicated how boys and girls are oriented in the world, how intellectually developed, etc.

Combinations of words and photos were offered in a variety of ways: sometimes only a photo was shown, sometimes words were attached to the photo that "by age" did not match the photo (that is, in the photo the child, when compared with his own words, was younger or older), and sometimes a portrait photographic and verbal portrait coincided.

Adults, in the end, made their own psychological verdict: they had to say whether the child liked to lie, whether he was quick-witted, whether he was friendly, affable or not. Psychologists, in turn, concluded how an adult sees a child - as still small or as already large. As a result, it turned out that children were evaluated mainly by what and how they said.

For example, when a participant in the experiment (be it a man or a woman - gender did not play a role) described his impression of a child who "said" about the "angry sun", then he perceived him as a little one, no matter how old the boy was ( or a girl - here the floor also played almost no role) looked in the photo. Moreover, it was “very childish” thoughts that had the greatest power, that is, having heard some strange fantasy, an adult was more likely to underestimate the child’s age than, on the contrary, add years to him if he suddenly said something smart.

It must be emphasized that we are talking only about a certain age, from 4 to 10. At earlier times, we evaluate child development mostly in appearance - how plump the cheeks are, how round the eyes are, and so on. But then the children fully master speech, the school is already shining for them, the world is getting bigger for them, social interactions are becoming more complicated - and here, in order to understand how adequate the child is to the world, one cannot do without words.
