Once the former theory might have been supported by a good amount of empirical studies, the latter did not account fully for the fresh conclusions in regards to only college students. Responding, Zajonc offered brand new confluence model, postulating you to definitely young sisters promote an opportunity for exercises, hence enriching the brand new mental connection with older children; the low intellectual show of simply children is actually related to this new undeniable fact that they cannot get by themselves of this possibility. Since the confluence model has created considerable discussion and you can debate, eg away from possible affairs anywhere between family unit members size and you may beginning order, in accordance with family SES (including, discover Steelman 1985; Zajonc 1986), a scientific take to of one’s model is still around presented.

As a way to account for brand new seen matchmaking between sibship size and you can rational function, Zajonc (1976) put the brand new “confluence design,” and this postulates that the rational environment yourself, discussed by the shared mental degrees of the mother and father and kids, is the reason new noticed matchmaking
