Briefings

University of Tübingen researchers demonstrated that crows process visual motion choices twice as quickly as humans and monkeys, completing the task in 235 milliseconds on average with high accuracy. This finding challenges assumptions about cognitive speed limits in avian intelligence and suggests crows may possess advanced pattern recognition capabilities. The study involved two specific crows performing a controlled visual discrimination task.

Key points

• Two carrion crows completed a visual motion discrimination task in 235 milliseconds on average.
• The crows maintained high accuracy while processing visual information faster than human and monkey benchmarks.

Context

This research challenges existing assumptions about cognitive speed limits in avian intelligence, suggesting crows may possess advanced pattern recognition capabilities. The study involved two specific crows performing a controlled visual discrimination task.

Limitations

The evidence is limited to a single experiment with only two crows. Results may not generalize to all crows or other species. The study does not specify the exact visual stimuli used or the specific task parameters beyond motion direction.
