Researchers Used Measures of Inhibition from When Children Were 21

Researchers used measures of inhibition from when children were 21 months of age to predict how they would react upon entering kindergarten.

A) That children who were inhibited earlier displayed more risky behavior when playing a ball-tossing game.
B) That children who were inhibited earlier displayed more risky behavior when playing on a mattress in a falling game.
C) that children who were inhibited earlier were less likely to play with other children, touch classmates, or even laugh.
D) That children who were uninhibited earlier had grown out of this tendency and interacted with other kids at about average rates.
