| Abstract: | In this study we investigated whether infant characteristics play a causal role in the occurrence of maternal abuse of offspring in rhesus macaques )Macaca mulatta) and whether abusive mothers differ from controls in their tendency to adopt alien infants in a cross‐fostering procedure. To this end, 13 infants born to mothers with a previous history of infant abuse were cross‐fostered shortly after birth with infants born to nonabusive mothers and subsequently observed for 12 weeks. Abusive mothers were significantly more likely to reject foster infants than control mothers were. When adoption was successful, all of the abusive mothers maltreated their foster infants whereas none of the control mothers exhibited infant abuse. These findings suggest that infant characteristics do not play an important causal role in the occurrence of infant abuse and that abusive mothers may differ from nonabusive ones in maternal motivation or reactivity to stressful procedures. |
