Spatial and Visual Maze Learning, and Motivation in Alus Musculus and Peroalyscus

Abstract
The present investigation compares performance and learning of 3 groups of adult mice: Mus musculus (wild and C57BL/6J) and Peromyscus maniculatus Bairdii on 2 types of water maze (spatial or visual) under 4 levels of motivation (55, 75, 95, or 115°F water temperature). The wild Mus learned most rapidly, the Peromyscus being the slowest to learn. Extremes of water temperature and the spatial discrimination task facilitated performance and learning.
