Extracts from Lashley's seminal study of rat pattern vision. (A) A sketch of the jumping stand apparatus introduced by Lashley to test rats in visual discrimination tasks (see Section 3.1 for a description). (B) An example of visual pattern discrimination, in which rats were trained in one of Lashley's experiments. (C) Alterations of the trained visual patterns (shown in B) to probe generalization of rat recognition in transfer trials. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
