Our mental ability to divide the complex world into categories makes our daily life much easier. But how do we categorize? What kind of stimulus properties do we assess? Researchers have come a step closer to answering these questions with the help of pigeons. They discovered that birds use different strategies to successfully learn categories. To gather data, the researchers used a novel research method. To this end, they combined so-called virtual phylogenesis, in which artificial stimuli are generated by computers, with a machine learning approach, namely an automated evaluation of the birds' pecking behavior.
