marginally significantp < 0.10
As can be seen in the figure, children showed significant shape responding for the clay, M = 0.64, t (74) = 5.16, p < 0.0001, and wood sets, M = 0.68, t (73) = 5.90, p < 0.0001, and marginally significant shape responding for the sand, M = 0.56, t (73) = 1.89, p < 0.10, and Styrofoam sets, M = 0.55, t (74) = 1.76, p < 0.10.
