Physiological responses to child stimuli in mothers with and without a childhood history of physical abuse.
The present study investigated changes in heart rate, skin conductance, and self-reported affect in response to child stimuli in mothers with and without a childhood history of physical abuse. The stimuli were videotape presentations of a smiling and crying infant. During baseline periods (prior to videotape presentations), mothers without a childhood history of abuse displayed a significant reduction in skin conductance, which was not observed in mothers with a childhood history of abuse, suggesting that mothers without a history of abuse habituated to the experimental setting. Although the two groups of mothers did not differ in self-reported affect or in heart rates in response to the crying and smiling infant, mothers with a childhood history of abuse showed increases in skin conductance while viewing the smiling infant, but not while viewing the crying infant. In contrast, mothers without a childhood history of abuse showed increases in skin conductance during the presentation of the crying infant, but not while viewing the smiling infant. Similarities between the skin conductance results for mothers with and without a childhood history of abuse and skin conductance data reported for physically abusive and at-risk mothers are discussed.
