Document Summary
Innate behavior i. ii. iii: performed by the animal without the need for practice or experience, genetically programmed (hardwired, characteristics. Intrinsic - animals lived in isolation will perform this behavior perfectly. Stereotypic - performed the same way each time by each individual of the species (variations) Inflexible - not modified by development or experience. Behavior: female sits in nest of eggs the entire time. Occasionally, an egg rolls out i. ii. iii: sign stimulus: see egg out of nest, female bends towards egg and rolls it back to its nest. Huge rs: put egg at different distances from nest. At any distance <2 ft, female will always roll the egg back. At distance >2ft, female leaves it = no fap. Any object <2 ft triggered fap. Female continued fap to completion: all kinds of strange object near nest, put egg near the nest, and took it away when fap started.
