To realise the potential of the VC, it is neces- sary to cultivate within it good group cohesion and vitality. Using empirical and experimental research methods, this study explores the ef- fect of users＇ trust in the VC Platform （VCP） on group cohesion and vitality and how brand and perceived privacy security can affect us- ers＇ trust in the VC. The research results indi- cate that the brand of the VCP can directly af- fect users＇ trust in the VC, and can also influe- nce it indirectly through users＇ perceived pri- vacy protection and perceived security protec- tion. Further, this study also confu＇ms that the performance of the VC （group cohesion and vitality） is significantly affected by users＇ trust in the VC. The results of this study can provide theoretical guidance for internet companies to maintain and enhance the value of VCs.展开更多

ERPs to the final word of sentences （half being semantically incongruent with the sentence and half congruent） were presented to French natives under 4 levels of degradation： no degradation, mild degradation （2 levels）, and strong degradation. Under mild degradation allowing controlled sentence-level processing according to behavioral data, the N400 effect （i.e., the N400 to incongruent words minus the N400 to congruent words） and a late positive complex were delayed and the latter effect was reduced. Under strong degradation allowing only automatic sentence processing according to behavioral data, no ERP effects remained. These results suggest that, unlike contextual effect found with single words （e.g., using word-pair or word-list paradigms）, ERP effects elicited by more complex contexts such as full sentences are generated by controlled but not by automatic mechanisms of speech processing.展开更多
