“…As an attempt to increase the knowledge about the effects of instructions on behavioral persistence, future studies could use more than two levels of instruction's completeness and examine the effects of these instructions in the presence and absence of the instruction giver (e.g., Donadeli & Strapasson, 2015;Kroger-Costa & Abreu-Rodrigues, 2012;Ramos et al, 2015) which could approximate the experimental condition to everyday situations in which people are faced by multiple verbal prompts and can have their behaviors observed by others. Furthermore, as it occurs with the immediacy of reinforcement (Bell, 1999;Grace et al, 1998a), the relative differences in response-rate requirements Lattal, 1989;Nevin, 1974, Experiment 5), and the response force (Luiz, et al, 2020(Luiz, et al, , 2021 our results demonstrate that different levels of instruction completeness can affect behavioral persistence when the reinforcement rate is the same between the components.…”
