Pigeons Can Solve a Task that Would Stump Us

Edward A. Wasserman Ph.D. on April 6, 2023

Associative learning is often deemed to be rigid and limited, yet this process enables pigeons to learn a categorization task that can stump more sophisticated forms of learning.

Racist Robots? Part of the Problem, Part of the Solution

Edward A. Wasserman Ph.D. on September 20, 2022

Do you think only people can become prejudiced? Recent work suggests that AI can also acquire biases. That fact may help us reduce social bias in published media.

Inventing the Lithophone: Intelligent Design Hits the Rocks

Edward A. Wasserman Ph.D. on August 30, 2022

We marvel at the products of human innovation and hail their inventors as geniuses. Learning more about the creative process behind their making tells a very different story.

Does Innovation Come "Out of the Blue"?

Edward A. Wasserman Ph.D. on August 22, 2022

Creative ideas are often bedecked with extravagant romance. Innovative ideas are believed to arise in a blinding flash, seemingly out of the blue. Let's take a look at this notion.

Writing Hit Songs—As If by Design!

Edward A. Wasserman Ph.D. on November 16, 2021

How do songwriters put lyrics to music? Do they wait for a burst of inspiration? Do they follow rigid rules? Do they have a clear end in mind? Or is the process more improvisational?

Trial and Error in Developing Vaccines

Edward A. Wasserman Ph.D. on May 17, 2021

Vaccine development can be a slow and uncertain matter—one often disparaged as ‘trial-and-error medicine.’ Is there no better way?

Keeping Pigeons Close to Our Hearts

Edward A. Wasserman Ph.D. on July 14, 2020

By keeping pigeons close to our hearts and seeing the world through their eyes, we learned a thing or two about the processes underlying our own classification of medical images.

Is the Coronavirus Our Worst Enemy? Or Are We?

Edward A. Wasserman Ph.D. on May 19, 2020

The coronavirus pandemic has been called a war in which the virus is our enemy. But another foe may be preventing us from defeating the virus. We may be our own worst enemy.

The Ultimate Game of Trial and Error: Lessons to Be Learned

Edward A. Wasserman Ph.D. on April 17, 2020

COVID-19 poses an even greater threat to our species than the Gulf Oil Spill. We are once again deploying trial-and-error learning to confront this challenge.

Truth or Consequences: The Stakes Couldn't be Higher

Edward A. Wasserman Ph.D. on February 18, 2020

How might we establish what is true? Science confronts this matter and provides methods to determine truth. Rejecting scientific truths is both consequential and dangerous.

What Drives Trump's Tweets?

Edward A. Wasserman Ph.D. on September 5, 2019

It might seem an odd occasion to distinguish the two key kinds of associative learning, but the war of words between Donald Trump and the Baltimore Sun provides a chance to do so.

Are We Just Making It Up As We Go Along?

Edward A. Wasserman Ph.D. on June 3, 2019

Experts laud the virtues of foresighted planning while they disparage a more improvisational lifestyle. Might trial-and-error more strongly control our lives than careful planning?

Google’s April Fools’ Pigeon Prank Proves More Than a Joke

Edward A. Wasserman Ph.D. on March 31, 2019

After Google proposed PigeonRank was behind its search function, we gave a small flock of pigeons a medical diagnostic test to assess its plausibility. The results were revealing.

Climate Change: The Conflict Within Us

Edward A. Wasserman Ph.D. on January 26, 2019

Most commentators frame the climate change debate as between political extremes. But, perhaps the more basic battle may be between clashing tendencies within each of us.

Time and Space May Be Perceived by a Common Brain System

Edward A. Wasserman Ph.D. on November 25, 2018

Einstein’s theory of relativity suggested that time and space are inseparable. Research has now revealed that people and animals use shared brain systems to judge time and space.

Dick Fosbury’s Famous Flop Was Actually a Great Success

Recent research suggests that brain evolution may have been driven by the feeding behaviors of our distant kin. Social factors may have played a smaller role than is believed.

Fake News Hijacks Adaptive Cognitive Processes
