Mechanisms of object recognition: what we have learned from pigeons.

摘要: Behavioral studies of object recognition in pigeons have been conducted for 50 years, yielding a large body data. Recent work has directed toward synthesizing this evidence and understanding the visual, associative, cognitive mechanisms that are involved. The outcome is likely to be non-primate species which computational best understood. Here, we review research suggest core set might present all vertebrates, including people, making an excellent candidate model study neural recognition. suggests error-driven learning participates category by recent neuroscientific basal ganglia, homologous these species, may implement stimulus-response associations. Furthermore, abstract representations can observed other vertebrates. Finally, there feedforward visual processing, central mechanism models primate ventral stream, plays role pigeons. We also highlight differences between people abilities, propose adaptive specializations explain them, such as holistic face processing rule-based primates. From modern comparative perspective, expected regardless under study. fact good idea aspects differ should seen advantage over animal models. much learn about human from studying “simple” brains
