Love math, but don’t care too much

As part of my job as a researcher and graduate student in the Department of Psychological and Brain Sciences, I invite parents and children to play math games in our lab. As I lead parents and children through studies about how children learn, I’ve seen very different attitudes in parents towards math. Some parents would happily talk about numbers and inferences in their daily interactions, and they make a lot of attempts to start a conversation about math…

People get “brain drain” when smartphones merely exist in room

Have you – at least for a moment – ever imagined throwing your smartphone out the window, especially when you are trying to focus on your work? Now you might have a justification for your impulse. Behavioral scientists recently found that if your smartphone is merely present in your room, and even if you are not consciously thinking of it, you may still be distracted…

The cognitive process behind categorizing objects

Conscious or not, we are faced with countless categorization decisions during our everyday lives. When organizing kids’ rooms, parents need to decide if various items are tools or toys, to know in which drawer to place them… No matter how fast and intuitive some categorizations may feel, the process of making any classification decision involves a chain of cognitive steps…

Using mathematics to study psychology. Part 2

[A picture of a human face made up of mechanical parts, like gears.]

In my last post, I explained the defining characteristics of cognitive models and the main steps to developing a cognitive model. In this post, I’ll discuss the advantages of cognitive modeling over alternative approaches to studying human cognition and behavior, and a precaution to be taken about interpreting modeling results…

Using mathematics to study psychology. Part 1

[A picture of a human face made up of mechanical parts, like gears.]

If you’ve ever thought about the life of a graduate student in psychology, you might have pictured someone who is asking research participants probing questions about their hidden thoughts, or perhaps someone who is discreetly observing human subjects completing some tasks while taking quick note of their behavior. In reality, we psychology students spend most of our time learning advanced statistical methods and grappling with quantitative analyses of noisy behavioral data that are difficult to interpret….

Heart rate variability: What it is and how it relates to mental health

A healthy heart is not a metronome. Even though most of us can follow our heartbeat with ease, in between each heartbeat is a period of time that varies in duration from one beat to the next. This difference in time between any consecutive heartbeat is known as heart rate variability (HRV), and researchers are increasingly using it as a tool to understand mental health…

Making and Reaching New Year’s Resolutions the SMART way

[A notebook sits in the middle of the photo with “2022” written in big words on the left side and “Goal” written in big letters on the right with one through four numbered under it. To the left is a bunch of flowers sitting on the table and to the right of the notebook there is a coffee cup with coffee in it.

It’s January 1st. You bought your notebook, numbered the page, and you’re ready; It is time to make some New Year’s resolutions. If you’re someone that regularly makes resolutions, you’re not alone. The start of a new year brings a natural push to start new routines or try to break bad habits. However, many people struggle to keep resolutions. The good news is, behavioral science and the theory of motivation tell us there are evidence-based strategies that can help…

Thinking about starting therapy but overwhelmed by the process of finding a therapist? You’re not alone. There are a lot of reasons that people don’t seek treatment. This post will discuss how to find a therapist and things to consider during your search. “Should I go to therapy? How do I know when it’s ‘time?’” The shortest answer is therapy can be appropriate at any time, as long as you want to be there. It is extremely common to seek therapy when we’re struggling with severe or minor difficulties…

A study on grammar and the bilingual brain

We humans have a unique capacity to acquire language, even as adults. However, if you have ever used Duolingo, you might have realized that children are more successful at acquiring languages than adults. This observation is puzzling; since adults are smarter than children, shouldn’t it be the other way around? One set of explanations for this paradox focuses on parsing — that is, applying our knowledge of grammar as sentences unfold incrementally…

Putting it into context: How psychology has shaped our knowledge of universal emotions

Posted by

[Yellow painted eggs with various facial expressions.]

What are common emotions experienced in your culture? In the United States, happiness, anger, sadness, and fear are considered common emotions. The traditional theory of emotion assumes emotions are universally recognized by all humans. This theory dominates pop culture, with movies like Pixar’s Inside Out, which features characters personifying five emotions that coordinate our every action, and items like Amazon’s Halo Watch, which claims to detect emotions based on tone of voice. Yet, it is not possible to determine what emotion someone is experiencing based only on their face or tone of voice. Instead, our brain makes a prediction that is influenced by past experience, the current context, and interoceptive signals from our body (e.g., heart and breathing rate, hunger cues) from a culture-specific perspective…
