Although the human experience is truly a unique one, it’s comforting to know that we all share some experiences and emotions. For example, we were all excited the day we were handed our very first motor vehicle driver’s license. You know, the one with the awkward smile and terrible lighting. When we first received our […]
Divided Attention
One recommendation to reduce COVID-19 transmission is to keep a distance of at least 2 meters/6 feet from others. If you are a pedestrian making your way through busy city streets, this advice is easier said than done. There’s a lot to keep track of to maintain distance with people coming from different directions and […]
We rarely listen to just one stream of information at a time. Whether we are at a dinner party, on a crowded bus, or talking on the phone while walking down a busy street, more often than not there are multiple voices that compete for our attention. People are generally very good at focusing on […]
Certain songs have a way of getting into your head and staying there for a while. We’ve covered the cognitive side of earworms before. These songs that haunt us tend to have a recognizable tempo or beat—usually one that we can move to. Lady Gaga has given us a number of earworms, including Poker Face, […]

People often do multiple things at the same time. We can talk on the phone while stacking the dishwasher, and some university students seemingly know how to type messages on their cell phones while listening to a lecture.

Put Tom Cruise and Dustin Hoffman together and you get Rain Man, the Academy-Award winning story of an autistic savant—played by Hoffman who received the Best Actor award for his performance—who turns out to have many unexpected talents. The clip below shows one famous scene, in which Hoffman knows within seconds that the waitress dropped […]
It is rare that we can do two things at once—if someone asks you to rub your stomach and pat your head, odds are that you’ll rub your head. A better strategy for a lot of different cognitive tasks is to switch between them. Switching typically comes at a cost, however. Switching can even negatively […]
Apparently the internet, video games, and social media are damaging our children’s development, and are responsible for the increase in autism over the last few decades—or so it has been claimed, although that claim hasn’t withstood scrutiny. Similarly, Wikipedia has an entry for something known as Internet addiction disorder, which apparently occurs when internet use […]
Think eating is easy? Think again. According to the World Health Organization, more than 1.9 billion adults were overweight worldwide in 2016. Of these, over 650 million were obese—a number equivalent to roughly twice the population of the United States. And most of the world’s population lives in countries in which obesity kills more people […]
