Innate and Learned Behaviour
- E.3.1 Distinguish between innate and learned behaviour
- Innate
- behaviour that is an
instinctive response fixed
- Learned
- behaviour modified from experiences
- E.3.2 Design experiments to investigate
innate behaviour in invertebrates,
including either a taxis or a kinesis
- Taxis = change in movement in response to a stimulus
- Maggots and lamp experiment
- Kinesis = change in activity rate in response to a stimulus
- Woodlice experiment
- prefer dark and damp places
- E.3.3 Analyse data from invertebrate behaviour experiments in
terms of the effect on chances of survival and reproduction
- Maggots
- move away from light
- Woodlice
- stay in the dark and damp places
- E.3.4 Discuss how the process
of learning can improve the
chances of survival
- away to avoid dangers that have previously come up
- hunting and obtaining food
e.g. bears learning to catch
salmon in rivers
- E.3.5 Outline Pavlov's experiments into conditioning of dogs
- E.3.6 Outline the role of inheritance and learning in the development of birdsong in young birds
- 1. Male birds use birdsong as a means of
communication - either signalling attraction
or establishing territorial boundaries
- 2.Most birds are born with a crude template song that is
genetically inherited
- 3. Whilst young, fledglings learn to expand the song by listening to, and
mimicking, the adult version (motor learning)
- 4. The possession of an innate template prevents the bird from learning the wrong
species song, however birds raised in isolation will lack the complexity that develops
from social interaction
- 5. Birds are generally selective in what song they learn (not any song can be learnt) and once learnt the song is
rarely modified
