Visual patterns used the test configural discrimination in rats. (A) The stimuli used by Eacott et al. [161], which did not enforce a strictly configural processing strategy, because of the unique features created by the intersection of their constituent elements. (B) The stimuli used by Davies et al. [172], which more properly enforced a configural processing strategy.
Panel A is modified from Eacott et al. [161]. Panel B is modified from Davies et al. [172].
