Crows Outsmart Humans
Two male crows have outperformed humans and monkeys in a classic psychology task, demonstrating powerful decision-making skills despite having smaller brains with a different structure
Two male crows have performed better than humans and monkeys in a classic psychology task designed to test decision-making skills, with the results published in Science. The task involved the crows using a touch-sensitive screen to indicate the direction of moving dots, with a correct response rewarded with a mealworm.
The crows were able to complete the task at their own pace, allowing them to choose their response when they were confident in their decision. This self-paced approach enabled the researchers to assess the crows' decision-making abilities in a more natural and intuitive way.
The research was conducted by Philipp Schmidbauer and Andreas Nieder, neurobiologists from the University of Tübingen in Germany. The study is part of a broader effort to understand the cognitive abilities of corvids, a family of birds that includes crows, ravens, rooks, jackdaws, and jays. Corvids have shown remarkable mental abilities in prior experiments, including the ability to build compound tools and plan multiple steps ahead.
One of the key findings of the study is that the corvid brain has a different structure than mammalian brains, with circuits that originate from a different part of the pallium. Despite this difference, the corvid brain has twice as many neurons as a primate brain of equal mass, which provides enormous processing power in a small and densely packed brain.
## Why it matters The study's findings have significant implications for our understanding of intelligence and cognitive abilities. The fact that crows are able to outperform humans and monkeys in a classic psychology task suggests that there may be multiple paths to achieving complex cognitive abilities. The study also highlights the importance of considering the unique characteristics of different species when assessing their cognitive abilities.
The research has the potential to inform the development of new approaches to artificial intelligence and machine learning, as well as our understanding of the evolution of intelligence in different species. As we continue to learn more about the cognitive abilities of corvids and other species, we may uncover new insights into the nature of intelligence and how it can be achieved in different ways.
