Limitations and future directions
Given its preliminary nature, this study presents some limitations. First, our sample consisted entirely of young adult women. Since gender differences significantly influence the processes of mental imagery, testing young adult men is essential to gain stronger insights and extend these results to the general population. Another limit concerns the sample size and the type of action imagined backward. We have chosen a complex imagining task, such as walking backward. Since the distance to be covered appears to be an essential factor in the equivalence of motor imagery timing (Papaxanthis et al.,
