Research reveals that our perception of multitasking is often an illusion – most cognitive tasks cannot actually be done simultaneously. Surprisingly, this illusion of multitasking can improve performance on activities, even when the tasks remain unchanged. Key Facts: Although multitasking refers to doing multiple things concurrently, true multitasking is rare for cognitive tasks requiring attention. …
A new study published in the Journal of Personality suggests that individuals exhibiting secondary psychopathic traits are perceived as less intelligent than those with primary psychopathic traits. The research examined how laypeople view the intelligence of others based on psychopathic traits. Here are some key findings: Individuals described as exhibiting high secondary psychopathy traits (impulsivity, …
Researchers studied if drinking alcohol makes people rate others as more attractive, which is sometimes called the “beer goggles effect”. They had male friends who regularly drink together rate attractiveness of photos after drinking alcohol vs. a non-alcoholic drink. Drinking didn’t affect attractiveness ratings of the photos.

New research reveals that the timing of our heartbeats relative to external events distorts our perception of how much time has passed. The study provides evidence that cardiac signals directly impact time perception on a moment-to-moment basis. Key Facts: Time perception was shown to contract during heart systole (when the heart contracts) and expand during …
Researchers have reconstructed a recognizable version of the Pink Floyd song “Another Brick in the Wall” directly from recorded brain activity. Using advanced machine learning techniques, the team was able to extract enough acoustic information from listeners’ brain signals to identify the song and recreate an intelligible version. Key highlights: Researchers recorded brain activity via …
Researchers have for the first time reconstructed all neurons and their connections in the brain of a fruit fly larva, revealing fundamental principles of brain organization. The study provides an important scaffold for understanding the neural basis of behavior in this model organism. Key Facts: The larval Drosophila brain contains around 3000 neurons. The full …
