A series of experiments involving these things involved the maxim “generalizations would come in due time” and was conducted by W. S. Small to focus on its subjects’ “natural proclivities.” (-5[1])Olton and Samuelson assessed reference and working memory in an experiment involving a “radial arm” one of these things. Distal cues in these things’ “oasis” type were added after (-5[1])an associative learning (-5[1])study by Richard Morris. (-5[1])Studies using these things, (-5[1])which led to Edward Tolman’s latent learning (10[1])theory, were used (10[1])to develop (-5[1])cognitive maps. (10[5])With Harvey Carr, (-5[1])John (10[1])Watson (10[3])conducted (10[1])a stimulus (-5[1])and response experiment (10[1]-5[1])using one of these things (10[1])that made (10[1])a “kerplunk” (10[4]-5[2])sound (10[3]-5[2])when (-5[1])a rat (10[3])ran into it. (10[3])For 10 points, name these structures that psychologists (10[1]-5[1])use to study (10[2])the navigation (10[2])of mice. (10[3])■END■ (10[21])
