Gesturing Reduces Effect of a Classic Optical Illusion, Study Finds

Sometimes our eyes can deceive us, as shown by a perception-bending optical illusion involving a pair of lines, or sticks, of equal length. One stick, framed by open fins at each end, appears longer to our eyes than an equally long stick framed by closed fins. Even when we use our hands to estimate the lengths of the sticks, we are susceptible to the illusion. Previous research has shown that the illusion collapses when we prepare to grasp the stick with our hands. New research adds to these findings by showing that the illusion also collapses when we use our hands to describe such an action.

Susan Goldin-Meadow explains how a new study published in the journal Psychological Science reveals that, under certain conditions, gesturing may enhance our ability to estimate the dimensions of objects even when our eyes deceive us. Read the entire news release here. 

 

Handwriting Beats Typing and Watching Videos for Learning to Read

There is something intrinsically satisfying about crafting a handwritten thank-you letter or jotting down a thoughtful note to a friend or loved one. With the advent of electronic correspondence, handheld texting, and voice-recognition software, handwriting skills are becoming less commonplace and even old fashion.

Apart from a seemingly less-personal approach to communications, does abandoning pen and paper have any negative impacts on how we learn languages?

New research published in the journal Psychological Science finds that handwriting helps people learn certain skills surprisingly faster and significantly better than learning the same material through typing or watching videos. Charles Blue talks with the authors, Robert Wiley and Brenda Rapp. 

Casual Sex, Self Esteem, and the Prejudices Women Face

Despite increases in gender equality and the normalization of casual sex in many cultures, the belief that women who engage in casual sex have low self-esteem remains widespread. New research examines this entrenched stereotype and finds no significant correlation between a woman’s sexual behavior and her self-esteem. Professor Jaimie Arona Krems discusses these findings.

Midnight Attack of the Earworms! How Stuck Songs Sap Sleep

At one point or another, you have had a song stuck in your head. These intrusive melodies, commonly called earworms, can sometimes provide amusement while other times they can be unrelenting annoyances. New research published in the journal Psychological Science reveals, however, that nighttime earworms can have a real negative impact on our quality of sleep, which can eventually lead to a cascading series of problems, such as lack of concentration, changes in appetite, lower work productive, among many others. 

Michael Scullin from Baylor University talks to us about his research examining this phenomenon of sleep-disturbing earworms and how popular tunes can impact our sleep.

From Activism to Radicalization: The Tipping Point of Unfairness

Conflicts driven by nationalism, ideologies, and cultures have become all too common.  What can psychological science tell us about the causes and mental processes that push people from activism to radicalization? To shine some light on this topic, we hear from Kees van den Bos at the University of Utrecht, who is an expert on the study of radicalization.

Out of the Box and Into the Lab, Mimes Help Us ‘See’ Objects That Don’t Exist

Human brains can do more than simply imagine the presence of nonexistent objects. Our minds can automatically create well-defined representations of objects that are merely implied rather than seen, like the obstacles in a mime’s performance. These findings could aid in the development of artificial intelligence related to vision and navigation by helping understand how humans perceive and navigate their environments. Chaz Firestone (Johns Hopkins University) and Pat Little (New York University) talk with Charles Blue about their Psychological Science paper on mimes and implied surface.

Special Episode: 6 Young Researchers Discuss the Forefront of Psychological Science

Many organizations present awards that recognize outstanding scientific achievement in a variety of disciplines, but these are typically given later in a scientist’s career. There are many scientists, however, who have made exceptional contributions and discoveries early in their careers. These researchers tend to be on the cutting edge of new and exciting fields. To recognize these deserving younger researchers, the Association for Psychological Science presents the Janet Taylor Spence Award for Transformative Early Career Contributions. Since its inauguration, the Spence Award has gone to more than 70 outstanding psychological scientists.

In this special episode of Under the Cortex, we talk with some of the most recent Spence Award winners. Each is considered one of APS’s most creative and promising investigators. Today, you’ll hear from six of them: Arielle Baskin-Sommers from Yale University, Sudeep Bhatia from the University of Pennsylvania, Eiko Fried from Leiden University, Celeste Kidd from the University of California at Berkeley, Steven Roberts from Stanford University, and Daisy Singla from the University of Toronto.

Emotion and Long-Lasting Attitudes and Opinions

Past studies have demonstrated that opinions based on hard facts and data can remain constant for many years, but new research published in the journal Psychological Science reveals that attitudes based on feelings and emotions can also stand the test of time. Charles Blue interviews Matthew Rocklage and Andrew Luttrell, authors of the Psychological Science article "Attitudes Based on Feelings: Fixed and Fleeting?" Read the full news release here.
