    Studies have shown that black students are subjected to higher disciplinary rates than whites, resulting in a number of negative life outcomes, including involvement in the criminal justice system.

    Using federal data covering 32 million students across 96,000 K-12 schools, researchers at Princeton University investigated the degree to which racial disparities in disciplinary action across the United States relates to county-level measures of racial bias.

    A work of art evolves from a series of decisions, as an artist combines brushstrokes, dance steps or musical notes to convey a feeling or idea. When a group of interacting dancers improvises a performance from a repertoire of possible movements, the dynamics of the artistic decisions become even more complex.

    Those pesky bees that come buzzing around on a muggy summer day are helping researchers reveal the genes responsible for social behaviors. A new study published this week found that the social lives of sweat bees — named for their attraction to perspiration — are linked to patterns of activity in specific genes, including ones linked to autism.

    Suppose you’re about to go snorkeling on the Great Barrier Reef or some other area of underwater beauty. You should be thinking about the wondrous marine life you’ll certainly see. But instead you’re fixated on the vanishingly small chance of coming eye to eye with a hungry shark.

    American adults of low socioeconomic status report increasing mental distress and worsening well-being, according to a new study by Princeton University and Georgetown University.

    Between the mid-1990s and early 2010s, self-reports of mental health declined among disadvantaged Americans ages 24 to 76. However, as socioeconomic status increased, mental health deterioration lessened or, in some cases, even improved.

  • Uncovering the sound of 'motherese,' baby talk across languages

    Thursday, Oct 12, 2017
    Across languages, Princeton researchers have identified consistent shifts in vocal timbre between mothers speaking to or reading to their children and speaking to other adults. This research into “motherese” was conducted in the Princeton Baby Lab and was led by postdoctoral research associates with the Princeton Neuroscience Institute, Elise Piazza and Marius Cătălin Iordan, as well as Casey Lew-Williams, an assistant professor of psychology.
  • Seven Princeton researchers receive NIH BRAIN Initiative awards

    Tuesday, Oct 24, 2017
    Three Princeton University projects, involving seven research labs, have been selected by the National Institutes of Health to receive funds through the federal Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative. Launched in 2013, the BRAIN Initiative is a large-scale effort to push the boundaries of neuroscience research and equip scientists with insights necessary for treating a wide variety of brain disorders such as Alzheimer’s disease, schizophrenia, autism, ep
