Two similar shapes, one with sharp angles while the other has rounded edges

Introduction

If you had to name some shapes "Bouba" and others "Kiki," which name would you give a pointy shape? How about a rounded shape? Would your friends have the same answers? In this activity, you will investigate the Bouba-Kiki effect to learn more about the human brain's fascinating connection between shapes and sounds.
