Innate and Learned Behaviour

E.3.1 Distinguish between innate and learned behaviour
1. Innate
  1. behaviour that is an instinctive response fixed
2. Learned
  1. behaviour modified from experiences
E.3.2 Design experiments to investigate innate behaviour in invertebrates, including either a taxis or a kinesis
1. Taxis = change in movement in response to a stimulus
  1. Maggots and lamp experiment
2. Kinesis = change in activity rate in response to a stimulus
  1. Woodlice experiment
    1. 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
1. Maggots
  1. move away from light
2. Woodlice
  1. stay in the dark and damp places
E.3.4 Discuss how the process of learning can improve the chances of survival
1. away to avoid dangers that have previously come up
2. 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. 1. Male birds use birdsong as a means of communication - either signalling attraction or establishing territorial boundaries
2. 2.Most birds are born with a crude template song that is genetically inherited
3. 3. Whilst young, fledglings learn to expand the song by listening to, and mimicking, the adult version (motor learning)
4. 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. 5. Birds are generally selective in what song they learn (not any song can be learnt) and once learnt the song is rarely modified
