reword "Within this study the independent variable were two different types of stimuli: a vibrotactile stimulation as the conditioned stimulus (CS) and an electro cutaneous stimulation as the unconditioned stimulus (US). The dependent variable wer the sensation levels and the pain rating. The results from the power study (Table 1) revealed that due to the relatively small effect sizes and restricted number of measurements, the number of participants need to be high to achieve 80% power (De et al., 2022). De et al. (2022) study used the Monte Carlo method to estimate power. In this method, several datasets are simulated under a set of simulation conditions. The proportion of these simulated datasets in which the Randomized Test (RT) leads to a rejection of the null hypothesis gives an estimate of statistical power for the given set of simulation conditions. A Monte Carlo RT with 1000 randomizations resulted in a p-value of 0.112. Hence, the null hypothesis of the RT could not be rejected at a 5% level of significance (De et al., 2022). The authors conclude that their customized single-case experimental design is a valuable tool for advancing the understanding of classical conditioning in pain. This approach may lead to
