Hown. a.u arbitrary units.not have rewardrelated qualities aside from social interaction, is advantageous for investigating the social reward elated activation aroused by social interaction per se. The job by frequency interaction effects (balltoss [highfrequency normalfrequency] buttonpress PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/26228688 [highfrequency normalfrequency]) also showed considerable activation in the precuneus. In contrast to ventral striatal activation, precuneus activation was not considerably correlated with scores on the Collectivism Scale. Hence, precuneus activation represents prevalent activation through the processing of social interaction, and was not straight modulated by preference for social interaction. The precuneus serves a wide range of selfrelated functions, such as episodic memory retrieval and selfprocessing operations480. Additionally to these taskdependent activations, the precuneus is prominently activated through the resting state (taskindependent activation)five. Inside the highfrequency condition, balltosses fromto participants had been improved in comparison to balltosses involving two other players. In this sense, the highfrequency situation of your balltoss run may possibly implicitly remind participants of their social relationships. Via this type of social interaction such as receiving reputation, humans update the selfrelated image52 represented inside the precuneus53. Moreover, reputationbased social behavior activates the precuneus54. Mainly because the precuneus is functionally connected with all the striatum, that is part on the reward system54, constructive selfimage can be translated to social reward represented in the ventral striatum6. Constant using the benefits of these previous studies, the precuneus activation observed in the present study could reflect popular functions involved in representing elevated social interaction as a social reward in the ventral striatum.Precuneus activation because of highfrequency effects through the balltoss game.Limitations. This study didn’t measure the expectation of enjoyment during the normal and highfrequency situations prior to the fMRI experiment. This was since we didn’t want the participants to anticipate the experimental manipulation, as this ought to be avoided in social neuroscience experiments. Hence, we measured the expectation of enjoyment (social reward) after the fMRI experiment. It is possible that this manipulation confounded our measurements of expectation, simply because humans anticipate rewards depending on earlier practical experience via reinforcement learning32,33. In such circumstances, the expectation values really should change direction, decreasing the difference involving the ratings for expectation and expertise. On the other hand, the expectation effects throughout the balltoss condition have been greater than 0, suggesting the presence 
of expectation effects, particularly for the balltoss situations. Although 32 participants appeared to believe the task manipulation (i.e they believed that they played with true players), as demonstrated by postexperiment interviews, it is attainable that the experiment was influenced to some extent by the usage of virtual players. In other words, this activity may have implicitly needed participants to take a type of `spectator’ view of social interaction55. In comparison with social interaction with real players, interaction with virtual players final results in less activation in social cognition elated places which include the superior temporal sulcus45. Nonetheless, even when a participant knows that the other players within a.
