Abstract

An important mechanism that is essential to avoid error and is possessed by human beings is the ability to monitor one’s own cognitive functioning, often referred to as ‘action monitoring’. Force production is one example from numerous real life situations which requires precise and continuous action monitoring, in which an irreversible false decision during its execution could lead to highly dangerous situations. Despite its importance, most of the studies in the area of action monitoring investigated tasks with discrete response parameters (i.e., left or right hand responses during flanker task), leaving action monitoring during continuous tasks like force production insufficiently investigated. The general aim of the present research was to learn more about the response dynamics during a simple one-dimensional force production task so that the monitoring processes involved in the brain during the task execution could be better understood. Therefore, two studies were conducted. The first study (N = 48) investigated how force execution of a simple one-dimensional force production task unfolds. The results from this study indicated that magnitude and timing of the force pulse (i.e., the response force parameters) were defined by the motor program even before response execution. As a force pulse is a ballistic process, an early definition of the response parameters seems to be an efficient monitoring strategy, as it allows for a fast force production and could provide information for error detection process. However, the process of determining these response parameters seemed to precede the process of determining the correctness of the response itself. The second study (N = 40) incorporated a modified Psychological Refractory Period (PRP) paradigm using two consecutive simple force production tasks, to investigate if force monitoring process during these two subsequent force tasks was modulated by different Response-Stimulus Intervals. This study showed successful replication of a PRP effect in an adapted force paradigm. On a behavioral level, PRP effect seemed to modulate not only Response Time, but also the response force parameters such as Peak Force and Time-to-Peak Force. Furthermore, PRP effect also seemed to modulate the neural correlates of force monitoring. Finally, three alternative models were postulated to elucidate how the different Response-Stimulus Interval affected the information processing stages of two subsequent simple one-dimensional force tasks. Taken together, findings from the second study could serve as an evidence that PRP effect is present in subsequent simple force production tasks, without the necessity of motor overlap between the first and the second task.
