In one study, the researchers observed the classroom participation of nearly 300 children in grade 2 and grade 4 over the course of a school year  Participation is measured by attentive behavior and distraction in class  The former refers to answering questions, raising hands to speak or participating in discussions, while the latter refers to behaviors such as small talk  In the experiment, half of the students stood at high desks while the other half sat
Many lively students prefer to stand up and have better concentration, while introverted students prefer to sit and listen, which is more conducive to improving their attention
 It was found that the students who stood up and listened to the class were more attentive than those who sat
