No evidence that testosterone reduces cognitive empathy

In the largest study of its kind, researchers found that testosterone administration did not affect cognitive empathy, a measure of the ability to recognize another’s feelings and motivations. The finding calls into question the theory that the symptoms of autism are caused by a hyper-masculinized brain.

‘Information gerrymandering’ poses a threat to democratic decision making
Pixelated image of a brain with red, blue, and purple regions

Information gerrymandering can change the way we think about political decisions, as depicted in this image of a gerrymandered mind. People must integrate disparate sources of information when deciding how to vote. But information does not always flow freely; it can be constrained by social networks and distorted by zealots and automated bots. Researchers showed that certain structures in a social network can sway the voting outcome of towards one party, even when both parties have equal size and each player has the same influence, a phenomenon they called “information gerrymandering." (Image: Alexander Stewart)

‘Information gerrymandering’ poses a threat to democratic decision making

Concern over fake news and online trolls is widespread and warranted, but researchers have identified another impediment to the free flow of information in social networks. The phenomenon, which they term “information gerrymandering,” arises from the structure of a social network and introduces bias into collective decisions.

Woodstock at 50

During three days of Woodstock in August of 1969, Anthony DeCurtis of the School of Arts and Sciences was 18, growing up in New York City and obsessed with the music that would form the foundation of his writing and teaching.
A society’s cultural practices shape the structure of its social networks

People learn either by observing those around them or by innovating. A new study from Penn biologists Marco Smolla and Erol Akçay demonstrates how cultures can evolve based on what kind of learning and skills are required to thrive within them.

A society’s cultural practices shape the structure of its social networks

Biologists Erol Akçay and Marco Smolla used mathematical models to show that societies that favor generalists, who have a wide range of skills, are less well-connected than those societies that favor specialists, who are highly skilled at a smaller number of traits.

A wearable new technology moves brain monitoring from the lab to the real world

Postdoc Arjun Ramakrishnan (left) and Penn Integrates Knowledge professor Michael Platt created a wearable EEG akin to a Fitbit for the brain, with a set of silicon and silver nanowire sensors embedded into a head covering like the headband seen here. The new technology led to the formation of a company called Cogwear, LLC.

When a fix for one vision problem causes another
A person sitting in front of a computer and a machine that tests vision.

The lab of neuroscientist Johannes Burge (above) focuses on how the human visual system processes the images that fall on the back of the eye. This line of work, closely related to a 100-year-old illusion called the Pulfrich effect, could have serious public safety and public health implications.

When a fix for one vision problem causes another

Aging diminishes the ability of the eyes to focus up close. New Penn research reports that monovision, a common prescription lens correction to mitigate this issue, can cause dramatic misperceptions of depth and 3D direction for objects in motion.
