It is often assumed when students fidget they are not on task. Two within-subject studies challenge this assumption by testing the effect of allowing fidgeting on three types of thinking: speeded mental math (Study 1), brainstorming and memory (Study 2). Study 1 showed that student's performance on speeded math was no different when performed in a regular chair compared to a chair that facilitated wiggling. In Study 2, students had a significantly higher number of creative ideas when sitting in a wiggle chair compared to sitting in a regular chair with "remain still" instructions. Memory did not differ. Results suggest allowance of natural movement during seated work will not hurt and may help performance.
