Flashcards in Fixed-action patterns Deck (10):

Define: fixed action pattern

inborn predisposition for a specific organism to behave in a certain way in response to a specific environmental stimulus.


Main 2 differences between FAPs and reflexes?

FAPs are species specific, and complex (often in a pre-set sequence).


How are FAP's species specific?

Behaviour is inherited by all members of one species ONLY; response to stimuli is very similar.


Can FAP's be sex-specific?

Yes - linked to courtship, sexual behaviour and nesting (mother finch and male three-spined stickleback)


At what time are FAP's demonstrated?

Whe organism is developmentally mature.


Why are FAP's difficult to change through learning?

As they are genetically programmed into the organism's nervous system


Why do higher order animals (humans have none) have fewer FAP's?

Because they are more capable of learning, therefore more of their behaviour is learned.


Non-gender examples?

Funnelweb spiders spin tubular webs
Atlantic ?? salmon swim upstream to spawn in the river they hatched in.
Honey bees return to hive and perform a dance to indicate the distance, direction and amount of nectar.


Male FAP?

• In breeding season, male three-spined stickleback’s belly turns red, builds nest and attacks any other of species that enter its territory.


Female FAP?

Mother filch builds nest, lays eggs, searches for food and returns to nest to feed young.
