5. Overview Innate behavior: - Develops independently of the environment
Learned behavior:
- Develops as a result of experience

6. Taxis Taxis: A movement towards or away from a directional stimulus
Planaria & Food
Qualitative and Quantitative Results

7. Kinesis
A response to a non-directional stimulus in which the rate of movement or the rate of turning depends on the level of the stimulus, but the direction of movement isn’t affected.
Cockroaches & light

8. Innate Behavior is: Heritable: DNA Intrinsic: Present in isolation
Stereotypic: Repetitive patterns
Inflexible: unchanged by experience
Consummate: Fully developed at first performance

9. Common Examples of Innate behavior:
Reflex

10. Common Examples of Innate Behavior:
Mature penguins tend to return to their birth places to breed

11. Non-heritable: observation & experience
Learned behavior is:
Non-heritable: observation & experience
Extrinsic: Effected by isolation
Permutable: pattern changes
Adaptable: capable of modification
Progressive: subject to improvement

12. Common Examples of learned behavior:
Chimpanzee’s learn to catch terminates by poking sticks into mounds

13. Common Examples of Learned Behavior
Birds learn to avoid eating orange and black caterpillars
Associated with bad taste

14. Learned Behavior & Survival
Based on environmental conditions, an animal can adjust its behavior and learn to survive difficult conditions
Adaptation

15. Development of Birdsong
Partially innate & partly learned
Chaffinch
Isolation:
Innate: correct length & number of notes
Learned: narrower frequencies & fewer distinctive phases
