To gain deeper insight into respective contributions of perceptual and motor experience of an observed action to anticipating its result, we examined the perceptual anticipation of players with different action roles in striking sports. Baseball pitchers and batters at both advanced and intermediate levels were asked to make a decision about whether to swing the bat when viewing a series of videos showing incomplete sequences of a model pitcher throwing a strike or a ball. The results revealed that first 100 ms of ball flight could discriminate advanced batters from intermediate pitchers and batters (with no difference between intermediate pitchers and batters). Particularly, advanced batters (perceptual experts with regard to pitching action) were statistically more accurate and less uncertain in making decisions than were intermediate players, whereas advanced pitchers (motor experts) only showed this tendency without reaching a statistically significant level. Moreover, advanced batters demonstrated greater perceptual sensitivity in discriminating when to swing at strikes over balls than all other players. Our findings suggested that when players were above intermediate level, perceptual experience of an observed action facilitated the perceptual anticipation to a greater extent than motor experience of producing it.

Emotion regulation (ER) strategies have a clear impact on mental health outcomes. In 2 studies (N = 695, N = 433) we investigated gender differences in the use of 2 ER strategies (reappraisal and suppression) to handle parent-child conflict in Taiwanese adolescents. We also identified the implications of these differences for some negative emotions (self-blame and resentment) and internalizing problems (psychosomatic symptoms and social withdrawal). Results of the correlation analyses in both studies indicated that reappraisal and suppression ER strategies are positively correlated only in male Taiwanese adolescents. Hierarchical regression analyses in the second study confirmed that reappraisal buffers male but not female adolescents against the negative effects of suppression on the arousal of negative affect and internalizing problems.
The hypothesis of strategic motives postulates that offering fairly in the Ultimatum Game (UG) is to avoid rejection and receive money. In this fMRI study, we used a modified UG to elucidate how proposers reached decisions of offering fairly and to what extent they considered offering selfishly with different stakes. We had proposers choose between a fair and a selfish offer with different degrees of selfishness and stake sizes. Proposers were less likely and spent more time choosing the fair offer over a slightly-selfish offer than a very selfish offer independent of stakes. Such choices evoked greater activation in the dorsal anterior cingulate cortices that typically involve in allocation of cognitive control for cost/benefit decision making. Choosing a fair offer in higher stakes evoked greater activation in the anterior cingulate gyrus (ACCg) and the areas that previously have been implicated in reward and theory of mind. Furthermore, choosing a slightly selfish offer over a fair offer evoked greater activation in the anterior cingulate sulcus, ACCg, ventral tegmental area (or substantia nigra) and anterior insular cortex signalling the higher gain and implying higher rejection risk. In conclusion, our findings favoured the hypothesis that proposers offer fairly based on the strategic motives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
