Special issue of APA’s Journal of Experimental Psychology: Animal Learning and Cognition, Vol. 47, No. 3, July 2021. This special issue represents a collection of 14 papers that help to display some of the diversity of ideas and approaches within this flourishing research area of comparative cognition.

In this study, the authors explored an animal model of such contextual cueing where repeated pairings of a particular visual context with a specific location of a target stimulus facilitate target search in humans.

This study presented pigeons with a visual categorization task and monitored their choice accuracy through their responses to different report buttons. The authors tracked the location of the pigeons' pecks to both the relevant and irrelevant attributes of the training stimuli using touchscreen technology in order to find out where the birds may have been attending during the course of categorization learning.

This article presents a quantitative framework for interpreting the results of multidimensional stimulus generalization experiments in animals using concepts derived from the geometrical approach to human cognition.

The results of this study suggest that animals other than humans and chimpanzees can discriminate the relation between relations.
