Converting Activations to Reaction Times

• How to map network activations to reaction times?

• Cohen et al used an iterative procedure.

• Assume that the output unit with the highest activation value would be the response given.

• Assume that response time is proportional to one minus the activation of that unit.

• Use the following equation to calculate response times (The variable A represents the activation of the winning unit).
  RT = C (1 - A) + RTmin

• C - the proportionality constant
• RTmin - minimum reaction time
