Smarter than a first-grader?
Date:7/23/2014

ow she passed it or what she understands about the task," Logan said, "so we don't know if the same cognitive processes or decisions are happening as with the children, but we now have evidence that they can. It's possible for the birds to pass it.

"What we do know is that one crow behaved like the older children, which allows us to explore how they solve this task in future experiments," she continued. Research on causal cognition using the water displacement paradigm is only beginning to get at what these crows know about solving problems. This series of experiments shows that modifying previous experiments is useful for gaining a deeper understanding.

The research on the crows is part of a larger project Logan is working on to compare the cognitive powers of crows with those of grackles. "So far, no smaller-brained species have been tested with the tests we use on the crows, and grackles are smaller-brained," she said. "But they're really innovative. So they may have a reason to pay attention to causal information like this."

The next research phase will begin next month, after the grackles' breeding season ends and they are ready to participate.
