lecture 1 Flashcards
what are the types of questions
ultimate, proximate
tinbergen’s contribution and 4 questions
experimental ethology, digger wasp experiment
ultimate: adaptive, evolutionary
proximate: developmental, causation
Konrd Lorenz’s contributions
founder of ethology
FAP
IRM
imprinting in geese, sensitive period
what is FAP in Geese
fixed action pattern
innate, triggered by environment, sequence unalterable, cannot be stopped once it has started, triggered under inappropriate circumstances
egg rolling, rolling a soccer ball
Karl con Frisch’s contributions
bees, sensitive to UV, dance pattern
what is the waggle dance of bees
waggle up middle of circle, angle according to the sub, 85-90% consensus on moving hives, distance of waggle is distance to source, more waggles is more communication
what are innate behaviours
instictive, naive animals do it, consistent, independent of rearing, doing it wrong is costly
what are examples of innate behaviours
mate recognition of ruddy ducks fiddler crab claw waves flicker attacking mustaches stickleback fish attacking red bellies mot mot eating insects and avoiding rattle snake patterns
what are learned behaviours
using past experience
can be changed by environment
what are mistakes costly for innate behaviours
so that bad alleles do not get contributed to the next generation
how are innate behaviours modified by environment
foraging wasps, prefering yellow and orange flowers, like yellow more
experiment
what is non-associative learning
habituation and sensitization
what is imprinting
sensitive period, neurons sensitive to environment
filial
habitat
sexual
what is associative learning
operant conditioning, classical conditioning, imprinting
what is classical conditioning
pairing an innate response with the conditioned stimulus
