Golden hamsters (Mesocricetus auratus) were reared from birth to adulthood in a spatially diversified situation (EG); their performances were compared with those of other hamsters housed in standard laboratory cages (SG). The task was to discriminate between 2 cubic volumes of different sizes followed by various test situations designed to define the respective parts played by the 3 spatial dimensions during perception. The results show that surfaces of volumes were mainly taken into account by EG subjects whereas width, alone, was used by the SG animals.
金黄地鼠（Mesocricetus auratus）从出生到成年都饲养在空间多样化的环境中（EG组）；它们的表现与饲养在标准实验室笼子里的其他地鼠（SG组）进行比较。任务是区分两个不同大小的立方体体积，随后是各种测试情境，旨在确定在感知过程中三个空间维度各自所起的作用。结果表明，EG组的受试地鼠主要考虑体积的表面，而SG组的动物仅利用宽度。
