ABSTRACT
This chapter discusses the problems of animal intelligence and what this idea of intelligence means in the field of animal psychology. The concept "intelligence," is borrowed from human psychology. Many animals, and certainly the higher orders, exhibit the phenomenon of attention, and even among the lower orders many animals show memory. So with the animals the concept of intelligence may have a more restricted meaning than in man. A more complex phenomenon is that of "homing" in animals. Under a "home" we may understand all places which for some reason the animal desires to reach again after having left it, be it because it finds a shelter there, or food, or because its progeny has been left behind. The finding of its home, if this is not directly perceptible by vision or scent or some other sense perception, requires the help of former experience, in other words of intelligence.
