The impact of robot speech on people's trust in him

10.10.2021

Oddly enough, trust is a very important aspect of human interaction with AI. At the same time, trust as a phenomenon is rather complicated and depends on both internal psychological factors and external ones.

Psychological theories describe the capacity for trust either as a stable trait of a person formed early in his life, or as a kind of state of mind that is influenced by numerous cognitive, emotional and social factors later in life. Trust is usually described by two main characteristics: a positive attitude towards an object and a willingness to be vulnerable, accepting the possible risks associated with trusting another.

Scientists from the University of Palermo conducted an experiment in which they studied the effect of robot speech on users' trust in it. The findings have so far been published in the arXiv preprint database. It is interesting that the robot that participated in the study did not speak to people, but aloud to itself, that is, it reproduced some analogue of a person’s internal dialogue. The study also involved 27 people: each was asked to fill out the same questionnaire twice - before interacting with the robot and after.

According to the volunteers, they began to trust the car more after interacting with it. In addition, the robot's self-talk reinforced this "feeling" by making it psychologically human-like and explaining its actions and intentions to humans. This approach, according to the authors, can be useful in the development of the relationship between people and machines, and hence in their increasingly serious introduction into our lives. The scientists' next step is a large-scale study involving more participants.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

New isotope of fluorine obtained 07.04.2021

Scientists at the National Superconducting Cyclotron Laboratory at the University of Michigan have obtained a new isotope of the chemical element fluorine, fluorine-13. Its atomic nucleus has nine protons and only four neutrons.

Fluorine is known as the most chemically non-metal among the chemical elements, exhibiting the strongest oxidizing properties. It is also the lightest element of the halogen group. Under normal conditions, fluorine is a poisonous gas of pale yellow color, its molecule consists of two atoms (F2).

All natural fluorine belongs to the only stable isotope, fluorine-19 (19F), which has nine protons and ten neutrons in its nucleus. But over the years of research, scientists have synthesized a number of other isotopes of fluorine from 14F to 31F and two nuclear isomers (18Fm and 26Fm). All these isomers are unstable and have rather short lifetimes. The longest-lived of these isomers, 18F, plays an important role in modern medicine, as it is used in positron emission tomography.

The new 13F isotope has the smallest mass number among fluorine isotopes, that is, with an equal number of protons, it has the smallest number of neutrons in the nucleus - only four. The isotope arose in the course of a nuclear charge exchange reaction, when one of the neutrons in the nucleus is replaced by a proton, nuclei of the light unstable oxygen isotope 13O when they irradiate a beryllium-9 (9Be) target.
