Decision Making

What do space invaders and sequential foraging have in common? Your heart.

Have you ever played a video game where the first few levels are relatively easy and slow, but as you progress, the game becomes harder and faster? Years back, I played Tetris, Frogger, PacMan, Space Invaders, Centipede, etc. I can remember my 10-year-old self (or my 22-year-old graduate student self) working so hard to beat the […]

Food for thought: What happens in the brain when you eat the whole bag of chips?

We all enjoy a tasty snack every now and then, and we usually have personal preferences for specific foods. Some of us may prefer chocolate, whereas others prefer potato chips. Sometimes we may get a little carried away snacking, ending up eating way more than we intended. So, what happens in the brain when we […]

Long shots into the future: Reducing delay discounting to improve decisions and well-being

Goals and temptations. The first, the very substance of life. But, oh, the second, they are everywhere! Both are desirable in their own ways, and they do not always align.

In all my years of schooling (four years of high school, four years of undergraduate studies, and six years of graduate school), one thing I have never been accused of is PREcrastination.

Shrinking boundaries during sequences of sequential sampling

It’s hot, very hot. And you are traipsing through the jungles of Sumatra in pursuit of that final bilingual participant who is as conversant in Minangkabau as she is in English. You need to test her in your lexical decision task to fulfil the sample size requirements of your OSF preregistration. You nervously scan the […]

Bringing a friend along for the ride: Why are we slower to respond when we’re talking to someone else while driving?

A computational model of mental processing speed in drivers who are holding a conversation suggests that having a passenger in the car is not a distraction, but it does make us more cautious and slower to make decisions. A reality of living in much of the United States and many other parts of the world […]

How long till today’s cigarette will make me ill? Time estimation revisited

Today’s cigarette may yield considerable satisfaction to a smoker, although that satisfaction will likely pale in comparison to the disutility arising from that person’s lung cancer in the future. Likewise, today’s Big Mac and extra-large bag of potato chips may gratify the consumer but the long-term consequences—from obesity to diabetes to heart attacks—are unlikely to […]
