This table shows the OTB training paradigm including task and training level, session length, number of possible reinforcers available per training level, training score points earned per level and cumulative training score (cumulative points). The day following completion of TIRA level 4, the full IRA task commenced. Following three IRA sessions, the TCP task was added to the training regimen on the next test day. Once subjects had completed the TCP task at level 5, the full CPR task began and tasks began alternating each test day such that on one test day the IRA task was presented and the next test day the CPR task was presented. After 1000 CPR reinforcers had been earned, the CPR task session length was reduced from 60 to 10 min and it was paired with TMTS task (50 min) which it preceded. At that point the schedule was IRA on one test day and CPR/ TMTS on the next test day. Following completion of TMTS at level 5, the DMTS task began. At this point the schedule was IRA on one test day and CPR/DMTS on the next test day. The day following the pairing of DMTS with CPR, the TPR task was introduced with and preceding the IRA task. Final OTB task administration was PR/IRA tasks on one test day and CPR/DMTS on the following test day.
