   Multiple regression analysis with interaction is used to examine whether the strength of the relationship between parental sensitivity ($x_{1}$) and the degree of security of the attachment relationship (y) depends on the child’s degree of shyness ($x_{2}$). The following estimated regression equation is found: $\hat{y} = 5+1.5x_{1}-0.1x_{2}+0.5x_{1}x_{2}$. Which interpretation of the interaction effect is correct?
