“…In the present study, happy, neutral, sad, and fear MEs were studied and the results showed that, in terms of ACC, happy ME had the highest, neutral MEs had moderate and sad and fear MEs had the lowest ACC, and the ACC of recognizing sad and fear MEs showed no significant difference. This indicated that happy MEs are easier to recognize than the other studied MEs, which is consistent with previous study findings (Schaefer et al, 2010 ; Kujawa et al, 2014 ; Kluczniok et al, 2016 ). In terms of RT, the RT of recognizing the happy ME were significantly shorter than the RTs of recognizing neutral, sad and fear MEs, while the RT of recognizing the latter three MEs showed no significant difference, suggesting individuals were more sensitive to happy ME than to the others.…”
