innate behaviour

• define innate behaviour

  • not learned
  • genetically determined response to a stimulus
  • significance lies in survival value
  • conscious areas of brain do not have to play a part
  • 4 types of innate behaviours

  Kineses

  Taxes

  Simple reflexes

  Instinctive behaviour
• Define kineses

  Response is related to intensity of NON DIRECTIONAL stimulus

  Involves a change in rate of movement/change in rate of turning

  EXAMPLE:

  Woodlice: dry environment, turn away, damp environment, go towards/rate of movement decreases
• Define Taxis

  Response, direction is determined by direction of stimulus

  Movement of whole organism TOWARDS or AWAY from DIRECTIONAL STIMULUS
• Define simple reflexes

  Automatic, rapid response to a stimulus e.g in a dangerous situation
• Define instinctive behaviour

  Sophisticated, unlearned behaviour

  Have a lot of survival value

  The same behaviour can be seen across a species

  E.g mating, defending territory
