Some studies have indicated that high response rate, produced by a exposition history to a FR, persist in a FI-cost. However, this is a controversial result. In studies which high response rate was observed, the FR extension history was 10 hours and in those which no persistence was seen the duration of FR ranged from 45 minutes to 3 hours. The present paper investigated the effect of the extension of history of reinforcement on behavioral persistence. Three groups of participants were exposed to different training extensions in FR (2 h 30 min; 5 h e 10 h), followed by an FI-cost. The results indicated a decrease on the response rate to most participants; when behavioral persistence happened was not correlated to history extension.
