Crows may make lightning-fast decisions, sometimes twice as fast as humans, study hints

Crows can evaluate visual information and make decisions in as little as 235 milliseconds, which is twice as fast as humans and monkeys. In a study, two carrion crows were trained to judge the direction of a moving dot pattern and accurately completed the task in under a quarter of a second. This rapid decision-making ability is attributed to the birds' compact nervous system.

  1. Crows make decisions twice as fast as humans and monkeys

    Crows can evaluate visual information and make decisions in as little as 235 milliseconds, which is twice as fast as humans and monkeys. In a study, two carrion crows were trained to judge the direction of a moving dot pattern and accurately completed the task in under a quarter of a second. This rapid decision-making ability is attributed to the birds' compact nervous system.

    Why it matters

    This study's findings have implications for our understanding of the evolution of intelligence and decision-making in different species. The research, conducted by the University of Tübingen, highlights the impressive cognitive abilities of crows, which are often underestimated due to their relatively small brain size. The study's results also raise questions about the neural mechanisms that enable crows to process visual information so quickly.

    What is confirmed

    • Crows make decisions in 235 milliseconds, twice as fast as humans and monkeys.
    • Crows can evaluate visual information twice as fast as mammals.
    • The birds' compact nervous system helps them handle tasks quickly.

    What to watch next

    • Further research on the neural mechanisms enabling crows' rapid decision-making
    • Comparison of crows' decision-making abilities with other bird species
    • Investigation of potential applications of crows' cognitive abilities in human technology
