Coffee hurts shopping

22.06.2022

People spend a lot of money while shopping, not only because they do it on an empty stomach and do not make a list, but also because they use caffeine.

If you're trying to cut down on impulse buying, a new study by experts has found that you should definitely refrain from drinking coffee.

A study by the University of South Florida found that caffeine affects not only what you buy, but also how much money you spend when shopping. The team of scientists conducted the experiment in retail stores, an industry that increasingly adds coffee shops near entrances.

In their study, experts found that shoppers who drank a cup of caffeinated coffee before going shopping spent about 50% more money and bought almost 30% more goods than those who drank decaffeinated coffee or water.

During the experiment, scientists installed coffee machines at the entrance to retail stores and home improvement stores in France and department stores in Spain.

“It is important to understand that caffeine, being a powerful stimulant that releases dopamine in the brain, excites the mind and body. As a result, a person becomes incredibly energetic, impulsive and less able to control himself, which leads to many unnecessary purchases and a lot of wasted money,” the host explained. study author Dipayan Biswas of the University of South Florida.

During the experiment, scientists installed coffee machines at the entrance to retail stores and home improvement stores in France and department stores in Spain. More than 300 shoppers received a free cup of coffee upon entry. One half drank coffee containing about 100 mg of caffeine, and the other half decaffeinated or water.

Then, leaving the stores, the participants shared their receipts with the specialists. For example, the team found that people who drank caffeinated coffee bought significantly more goods and spent more money than those who drank decaffeinated coffee or water.

People who drank a cup of caffeinated coffee before going shopping spent about 50% more money.

Moreover, scientists have found that caffeine also affects what kind of goods a person buys. Those who drank caffeinated coffee bought more non-essential items, such as scented candles and perfumes. However, the difference between the two groups was minimal when it came to essential items such as kitchen utensils or storage baskets.

After conducting another experiment that dealt with online shopping, the experts got similar results. They divided 200 business school students into those who drank caffeinated coffee and those who did not, and asked them to select items from a pre-prepared list of 66 options. As a result, those who used caffeine made more impulse purchases.

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 ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

SeeDevice PAT-PD image sensors 29.08.2020

Even the appearance on the market of smartphones with image sensors with tens of megapixels cannot be called a revolution. It is rather an evolution - an impressive development in its capabilities, which does not change the basic principles of creating light-sensitive image sensors. The revolution in this area is yet to come. Perhaps it will be brought closer by the efforts of SeeDevice, which claims to develop an extremely sensitive image sensor that works on new principles.

The image sensor proposed by SeeDevice is called PAT-PD (Photon Assisted Tunneling-Photo Detector) - a photon tunneling photodetector. The PAT-PD sensor "virtually eliminates photon leakage", which promises to capture images in the visible region with minimal light. Below you can compare the image at 0,1 lux (moonless night) on a DSLR with a 24,2 MP sensor and on a PAT-PD sensor. The image from the latter clearly wins compared to the image on the "stock" camera.

PAT-PD sensors can prove themselves not only as a tool for "photos in insta". They open up a new perspective both in the field of image sensors for autopilots and medical sensors.

The new sensors are capable of tuning to a given photon detection wave. For example, they can determine the composition of blood in blood vessels through the skin and detect the level of cholesterol, glucose, or other substances.
