Vocabulary Networks: Program-14

  Use these boxes to set the basic parameters for your model

  NTWK sets up the network for this simulation. Choose a number between 0000 and 9999 for this parameter.
  

  nEv sets how many events will occur in your simulation. Choose a number between 0 and 800 for this parameter.
  

  mEv controls the spacing of your events. Choose a number between 100 and 1500 for this parameter
  

  rEv determines which words are affected by your instructions. Choose a number between 0 and 9999 for this parameter.
  

   




  This simulation set illustrates how a vocabulary network
  responds to randomly occurring events when each event
  raises the activation threshold of a single word.
  The program builds a 1000 word network and lets it
  settle into a stable attactor state. The program then
  implements nEv attrition events distrinuted over
  mEv updates.
 
  THINGS TO DO.
  Find a network with a high level of activation.
  Set nEv to 20, and set mEv to 1500.
  How does the network respond to these parameter values?
  How is the attrition curve affected when you vary the
  value of the mEv parameter?
  How do the nEv and mEv parameters interact?
  Would you get the same results with a smaller network?

  QUESTIONS TO ASK.
  how big a ripple does an event typically make?
  How long do these ripples typically last for?
  Are all networks equally susceptible to events?
  What happens when you vary the value of parameter rEv?
 
  What implications does this set of behaviours have
  for theories of L2 vocabulary acquisition?
