Results across the nine observation sessions. The scatterplot (with
best-fitting regression line; a) shows the relation between the mean
number of “what” spatial types each child and his or her parent
produced, separately for boys and girls. The bar graphs (b) show the
mean number of “what” spatial types produced by parents (left) and
children (right), separately for boys and girls. Error bars show ±1
SEM. The model (c) illustrates the effect of
children’s sex on children’s production of “what” spatial types, as
mediated by parents’ production of “what” spatial types. Asterisks
indicate significant paths (*p ≤ .05,
**p ≤ .01, ***p ≤ .001).
