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. ... >>

Words and their emotional coloring 11.01.2019

Researchers at the University of Göttingen studied how the brain processes words to associate positive or negative emotions with them.

In the human mind, many objects and people in everyday life have an emotional meaning. For example, a pair of woolen socks has emotional value if it was the last thing a grandmother knitted before she died. The same applies to words. The stranger's name doesn't have an emotional connotation for you at first, but if a love relationship develops, then even the name suddenly takes on a positive connotation.

Scientists from the Institute of Psychology. Georg Elias Müller at the University of Göttingen analyzed how people attach emotional meaning to initially neutral signs, words and faces. For hours, participants explored these connections through a process of systematic rewards and losses. For example, if they received money every time they saw a certain neutral word, it acquired a positive emotional connotation. Conversely, if participants lost money every time they saw a certain word, it became negatively colored. The study also showed that people reinforce positive associations much faster than neutral or negative ones.

Using electroencephalography (EEG), the researchers also analyzed how the brain processes various stimuli. The brain usually determines whether an image or word is positive or negative in about 200-300 milliseconds. “Words associated with loss elicit specific neuronal responses in the visual cortex in as little as 100 milliseconds,” says Dr. Louise Kulke, first author of the study. “In this way, the brain instantly recognizes how important a new word is to us, especially if it is value is negative."

It also seems to matter whether the word is already known to the subject (for example, "chair" or "tree"), or whether it is a fictitious word that does not exist in the language (for example, "napo" or "foti"). Thus, the existing semantic meaning of the word also plays a role in the nature of the emotions that we attach to it.
