Intro Flashcards
Ethology
roots of modern behavioural biology
Umwelt
how organisms subjectively perceive their environment (inner worlds)
Markwelt
objective reality, ie what a spectrometer detects
Skinners hypothesis: Animals are a blank slate
FALSE
ethologists main ideas
sensory bio- waggle dance
learning- behavioural development
field bio- mating behaviour
Innate realising mechansims
fixed actions are the result of a particular “releaser” or stimulus–> suggesting a direct correspondence between an elicitor and specific behaviour
Behaviorists
focus on mechanistic studies of basis of behaviour in the lab
behavioural tendencies
Classical and operant conditioning
result of history and reinforcing experiences
Releasor with innate mechanisms –>
activation of instinct (fixed action pattern)
imprinting
includes both learning and innate behaviour and is irreversible. animals form attachments and learn identity in this time.
sensitive period
a time in imprinting- an early restricted period during Development where certain behaviours can be gained… ie who ever is next to goose when born=mother
digger wasps (Not all tasks are created equal)
Nikko Tinbergen-fly in circle before foraging trip to evaluate local landmarks so it knows where to come back. If the landmarks are moved –> wasp retires to new spot with landmarks
importance of digger wasp experiment
shows animals are not blank slates… ie wasps can learn visual aspects very fast
mating strategy
90% all birds = monogamous (1 partner)
90% of all mammals = polygynous
infanticide
males kill their own offspring
ie lions kill their own cubs
females may mate with many males so they don’t know which ones are their pwn cubs
