Dikes and Rivers

• Subjects alternate producing time intervals of a short and a long duration.
• Initially, short is 2 seconds and long is 3.1 seconds
• They receive feedback on whether their estimate is within +/- 12.5% of the target, and receive “too short” or “too long” as feedback otherwise.
• After a number of trials, the criterion for the long interval starts to change
• 
• Short intervals are also effected and vice versa
