Artificial Intelligence is Teaching Us New, Surprising Things about the Human Mind

April 1, 2023

The world has been learning an awful lot about artificial intelligence lately, thanks to the arrival of eerily human-like chatbots.

Less noticed, but just as important: Researchers are learning a great deal about us – with the help of AI.

AI is helping scientists decode how neurons in our brains communicate, and explore the nature of cognition. This new research could one day lead to humans connecting with computers merely by thinking–as opposed to typing or voice commands. But there is a long way to go before such visions become reality.

I say dog, you say chicken? New study explores why we disagree so often

March 17, 2023

Is a dog more similar to a chicken or an eagle? Is a penguin noisy? Is a whale friendly?

Psychologists at the University of California, Berkeley, say these absurd-sounding questions might help us better understand what’s at the heart of some of society’s most vexing arguments.

Research published online Thursday in the journal Open Mind shows that our concepts about and associations with even the most basic...

Even in small businesses, minimum wage hikes don't cause job losses, study finds

March 14, 2023

Restaurants, retail stores and other small businesses, long thought to be vulnerable to increases in the minimum wage, generally do not cut jobs and may actually benefit when governments raise minimum pay, according to a new study co-authored at UC Berkeley.

The prevailing wisdom among many business owners and policymakers is that when the minimum wage rises, smaller low-wage employers suffer more from higher labor costs and are more likely to cut jobs. But the...

School Discipline Can Be Predicted, New Research Says. Is It Preventable?

April 18, 2023

A new study by UC Berkeley researchers reveals alarming racial disparities in school discipline rates, with Black students facing a 50x higher risk of discipline than their white counterparts. The study highlights the "dynamic" nature of discipline throughout the school year, with rates decreasing before major vacations and increasing when classes resume. This real-time data is critical for educators to intervene before incidents occur and reduce escalating school tension.

Jason Okonofua, assistant professor of psychology at UC Berkeley, and the study’s...

People Differ Widely in Their Understanding of Even a Simple Concept Such as the Word ‘Penguin’

April 25, 2023

The Merriam-Webster dictionary defines the word “penguin” as “any of various erect short-legged flightless aquatic birds (family Spheniscidae) of the southern hemisphere.” That description seems simple enough, but definitions are not what people have in mind when they actually use words. Instead people think of concepts: the myriad properties, ideas, examples and associations that spring to mind when we think about a word.

Our concepts are crucial to exactly what we mean when we use language, and new research has found that the concepts people hold, even for a word like penguin,...

What can psychology teach us about AI’s bias and misinformation problem?

June 23, 2023

AI and misinformation

Knowledge may be power. But what if the information that leads to that knowledge is wrong?

To Celeste Kidd, assistant professor of psychology at UC Berkeley, the answer is simple: It’s dangerous and perhaps the most concerning aspect of generative AI’s rapid expansion.

Systems like ChatGPT, Stable Diffusion and DALL-E have rippled...

Deep sleep may mitigate Alzheimer’s memory loss, Berkeley research shows

May 4, 2023

Researchers from the University of California, Berkeley have uncovered a significant breakthrough in the fight against Alzheimer's disease. According to their latest study, deep sleep can help protect against memory loss in older adults who are at a heightened risk of developing the disease. The researchers found that deep, non-REM slow-wave sleep can act as a "cognitive reserve factor" that may increase resilience against a protein called beta-amyloid, which is linked to memory loss caused by dementia.

Psychology study reveals goal-oriented rewards as key factors in decision-making

July 17, 2023

Groundbreaking research from UC Berkeley’s Department of Psychology is shifting the understanding of human decision-making processes by highlighting the importance of goal-oriented rewards. Conducted by Berkeley Psychology Professor Anne Collins and Berkeley Psychology doctoral student Gaia Molinaro, the study suggests that the value people attribute to outcomes is subjective, and heavily influenced by their personal goals and the context of the decision.

"Value isn't just determined by an objective reward or outcome,” Collins said. “Our...
