| The Joint Simon Effect is a spatial stimulus-response compatibility effect that appears when two participants complete complementary components of a standard Simon task. In order to investigate the development of children’s joint action ability and combination types’effect on Joint Simon Task.122 preschool subjects in a kindergarten of Hangzhou were randomly selected. Children participants were from different grades:the first grade and the third grade. The subjects of the same grade were randomly paired to do the task.The results showed that:(1) For the younger children, the difference between spatially compatible trials’ accuracy and spatially incompatible trials’was not significant. For the older children, spatially compatible trials’accuracy was higher than patially incompatible trials’(t(61)=-4.554, p<0.05, r2=0.254). For all the children, spatially compatible trials’reaction time was shorter than patially incompatible trials’(t(41)=-3.218,p<0.05, r’=0.202; t(60)=-4.980, p<0.05, r2=0.292); (2) For boys and girls, spatially compatible trials’reaction time was shorter than patially incompatible trials’(t(51)=-4.565,p<0.05, r2=0.290;t(50)=-3.108, p<0.05, r=0.162). Boys’Social Simon Effect was more obvious than girls’(F (1,102>=5.109, p<0.05, ηp2=0.050); (3) For the same gender combination, spatially compatible trials’reaction time was shorter than patially incompatible trials’(t(36)=-3.264, p<0.05, r’=0.228; t(32)=-4.809, p<0.05, r-=0.420); For the same gender combination, the difference between spatially compatible trials’reaction time and spatially incompatible trials’ was not significant(t(32)=-1.805,p>0.05, r2=0.092).The conclusions drawn from the study list as follows:(1) Children’s Social Simon Effect gradually develop, the older children’s performance are more stable; (2) Children’s Social Simon Effect have gender difference, boys’ Social Simon Effect are more obvious. (3) Social Simon Effect are related with children’s combination types. The same gender combination appear with Social Simon Effect, but the different gender combination do not. |
