Spontaneous communication about number. Upper: A homesigner describing a vignette in which 10 sheep (Left) stand in (Center) a pen (Right). Note that the homesigner incorrectly extended nine fingers to describe the number of sheep. Lower: The number of fingers the homesigners extended (y axis) as a function of the number of objects actually shown in the vignette (x axis). Because not all participants produced an equal number of gestures in the stories, the weighted average correlation coefficient is shown.
