|
an example that FAP is stereotyped
|
spider cupienniuns salei: building nest made of silk from silk glands.Constructed stereotyped stages. (Baseplate->cup->lay eggs ->cover eggs and seal.
-always use 6400 spinning movements Experiment: 1. after baseplate finished, a spider moved by experimenter to new spot->spider does not make a new baseplate 2.silk removed from silk glands->spider still perform 6400movements even thought nothing is being produced -Single large FAP built into the spider's generic structure |

|
"plan of attack" to study inherited behavior patterns
|
1.make ethogram (descrition of behavior)
2.sort out inherited from learned from taxis 3.characterize stimuli involved in traggering FAP 4.determine the role of "internal state" (developmental or motivational) |
|
|
Deprivation experiment
examples |
-require releasers
1.Shrikes and wasps: correct, complete FAP for wasp capture and sting removal 2.Squirrels and nuts:Naive squirrels "buried" nuts on the wire floor of their cages without prior experience 3.Egg retrieval by greylaf geese. Movement completed even without egg |

Examples of releasers
|
-flickers: males recognize females by lack of "mustache" marks
-beavers; repair breaks in their damn. Triggered by the sound of running water -brooding, chicken and turkey:maternal behavior released by the peeping sounds made by the chicks |
