Abstract Gilead et al. present a rich account of abstraction. Though the account describes several elements which influence mental representation, it is worth also delineating how feelings, such as fluency and emotion, influence mental simulation. Additionally, though past experience can sometimes make simulations more accurate and worthwhile (as Gilead et al. suggest), many systematic prediction errors persist despite substantial experience.

Abstract Purpose Action observation (AO) during motor imagery (MI), so-called AO + MI, has been proposed as a new form of non-physical training, but the neural mechanisms involved remains largely unknown. Therefore, this study aimed to explore whether there were similarities in the modulation of short-interval intracortical inhibition (SICI) during execution and mental simulation of postural tasks, and if there was a difference in modulation of SICI between AO + MI and AO alone. Method 21 young adults (mean ± SD = 24 ± 6.3 years) were asked to either passively observe (AO) or imagine while observing (AO + MI) or physically perform a stable and an unstable standing task, while motor evoked potentials and SICI were assessed in the soleus muscle. Result SICI results showed a modulation by condition (F2,40 = 6.42, p = 0.009) with less SICI in the execution condition compared to the AO + MI (p = 0.009) and AO (p = 0.002) condition. Moreover, switching from the stable to the unstable stance condition reduced significantly SICI (F1,20 = 8.34, p = 0.009) during both, physically performed (− 38.5%; p = 0.03) and mentally simulated balance (− 10%, p < 0.001, AO + MI and AO taken together). Conclusion The data demonstrate that SICI is reduced when switching from a stable to a more unstable standing task during both real task execution and mental simulation. Therefore, our results strengthen and further support the existence of similarities between executed and mentally simulated actions by showing that not only corticospinal excitability is similarly modulated but also SICI. This proposes that the activity of the inhibitory cortical network during mental simulation of balance tasks resembles the one during physical postural task execution.

Upcycled food, a new kind of food, provides an effective solution to reduce the food waste from the source on the premise of food security for human beings. However, the commercial success of upcycled food and its contribution to environmental sustainability are determined by consumers’ purchase intentions. In order to overcome consumers’ unfamiliarity with upcycled food and fear of new technology, based on the cue utility theory, we adopted scenario simulation through online questionnaires in three experiments to explore how mental simulation can improve consumers’ product evaluation and purchase intentions for upcycled food. Through ANOVA, the t-test, and the Bootstrap methods, the results showed that, compared with the control group, consumers’ product evaluation and purchase intentions for upcycled food in the mental simulation group significantly increased. Among them, consumers’ inspiration played a mediation role. The consumers’ future self-continuity could moderate the effect of mental simulation on consumers’ purchase intentions for upcycled food. The higher the consumers’ future self-continuity, the stronger the effect of mental simulation. Based on the above results, in the marketing promotion of upcycled food, promotional methods, such as slogans and posters, could be used to stimulate consumers, especially the mental simulation thinking mode of consumer groups with high future self-continuity, thus improving consumers’ purchase intentions for upcycled food.
