Operant behavior typically occurs in bouts and pauses. The microstructural analysis of bouts and pauses reveals important and separable information about the physical characteristics of the operant and the motivation behind it. An analysis of interresponse times (IRTs) often reveals a mixture of two exponential distributions. One corresponds to short IRTs within ongoing response bouts, reflecting motor properties of the operant, and the other corresponds to longer intervals between bouts, reflecting the motivation behind the response. Partitioning responses into bout initiations and within-bout responses via this two-mode framework reveals the mechanisms underlying behavior maintenance and change. This approach is used in the fields of neurotoxicology, behavioral pharmacology, and behavioral neuroscience to disentangle the contribution of motivational and motoric variables to the pattern of operant behavior. In this article, we present a primer aimed at providing essential concepts related to the analysis of response bouts and temporal dynamics of operant performance.

Long-range intentions are a vital feature of real-world voluntary action, but have not been extensively studied in relation to their neural correlates. The current study adopted a procedure instead that previous highly repeatable and single decision point paradigms, in which voluntary action (generated by a random ratio (RR), yoked random interval (RI) reinforcement schedule) could be compared with a yoked condition in which participants responded to an external cue. Participants were required to reach the highest reward rates they could in the RI schedule, which offered an indicator of the extent to which long-range intentions have been formed. A classical RP amplitude occurred preceding participants’ keypress action in the current study. EEG amplitudes and EEG variability decreased significantly prior to voluntary action, compared to externally triggered action. These results extend previous findings regarding voluntary action arising from a particular set of long-range intention-based processes, rather than the outcome of stochastic neural fluctuations. Notably, EEG amplitudes decreased significantly differently prior to higher RI-reward rates (i.e., higher plane of long-range intentions formed). The novel experimental paradigm suggests a possible contribution of long-range intentions on the neural activities stage prior to voluntary action.

Most studies have been criticized for failing to capture the important features of consciousness in human nature. Conscious intention can be a promising pointcut to grasp consciousness and orient voluntary action. The current study adopted a random ratio (RR), yoked random interval (RI) reinforcement learning schedule instead of the previous highly repeatable and single decision point paradigms, aimed to induce voluntary action with the conscious intention that evolves from the interaction between short-range-intention and long-range-intention. Readiness potential (RP) -like-EEG amplitude and inter-trial-EEG variability decreased significantly prior to voluntary action compared to cued action, for inter-trial-EEG variability, mainly featured during the earlier stage of neural activities. Notably, (RP) -like-EEG amplitudes decreased significantly prior to higher RI-reward rates responses in which participants formed a higher plane of conscious intention. The present study suggests the possible contribution of conscious intention-based processes to the neural activities from the earlier stage prior to voluntary action by a novel experimental paradigm.
