Normal-son families (N=6) and aggressive-son families (N=6) were videotaped engaging in a 50-minute discussion of questionnaire items designed to…

Under consideration were: (1) the effects of stress on the parental preferences of young infants; (2) the effects of the presence of one parent on the interactions within the other parent-infant dyad; (3)…
