It’s clear that time and numbers are related in daily life, says Denise Wu of National Central University of Taiwan, who cowrote the new study with Acer Chang, Ovid Tzeng, and Daisy Hung. Numbers are used to represent distance and size, and to go to a farther place usually takes a longer time, for example.
But, she says, “Because the tradition of psychology is to manipulate one key variable of interest while controlling other confounding variables as much as possible, these domains were treated independently.” Recently, more researchers have started looking at how time and numbers are associated. Wu and her coauthors wanted to look more closely at this relationship, so they came up with a way to look at how numbers interfere with people’s perception of time.
In one experiment, each participant sat in front of a computer screen while a single-digit number appeared on the screen for a short time less than a second. After the number disappeared, the word “NOW” appeared on the screen, and the participant was supposed to hold down a key on the keyboard for as long as they thought the number had been displayed. The interaction between time and number was clear: after seeing a large number, like 9, people held the key down for longer than they did for a smaller number, like 2.
In another experiment, people saw a green dot for a short time. When they were asked to press the key, their key-press responses were accompanied by a number on the screen. In that case, they held down the key longer if they saw a small number and for a shorter time if they saw a large number. Wu thinks that happens because the small number makes people think they haven’t held down the key for long enough yet.
“We are really excited about this because this means the influence of the digit is so automatic and so immediate,” she says. The results suggest that the brain somehow processes time and the size of numbers together—possibly even with the same neurons. So, maybe instead of having different parts of the brain devoted to different kinds of measurement, there’s some part of the brain that is generally responsible for thinking about magnitude.
“It shows that it’s not like, mentally, we have a clock and it is immune to all the other information,” Wu says. Instead, your concept of time is responding to other things going on in the brain. In this case, it’s numbers, but it might also be influenced by emotion. For example, we all know that time passes more slowly in a boring meeting than when you’re chatting with a friend; maybe this is related to the ways that timekeeping links to other functions in the brain.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
