Two experiments examined whether 18-month-olds learn from emotions directed to a third party. Infants watched an adult perform actions on objects, and an Emoter expressed Anger or Neutral affect toward the adult in response to her actions. The Emoter then became neutral and infants were given access to the objects. Infants' actions were influenced by their memory of the Emoter's affect. Moreover, infants' actions varied as a function of whether they were currently in the Emoter's visual field. If the previously angry Emoter was absent (Experiment 1) or turned her back (Experiment 2), infants did not use the prior emotion to regulate their behavior. Infants learn from emotional eavesdropping, and their subsequent behavior depends on the Emoter's orientation toward them.  相似文献

Disorganized Infant Attachment Classification and Maternal Psychosocial Problems as Predictors of Hostile-Aggressive Behavior in the Preschool Classroom   总被引：7，自引：0，他引：7

This study of 62 lowincome families examined the relation between maternal and infant measures assessed at 18 months infant age and child behavior problems at age 5 as rated by preschool teachers. The infancy assessments included measures of mother-infant interaction, maternal psychosocial problems, infant cognitive development, and infant attachment security, including the disorganized/disoriented classification. The strongest single predictor of deviant levels of hostile behavior toward peers in the classroom was earlier disorganized/disoriented attachment status, with 71% of hostile preschoolers classified as disorganized in their attachment relationships in infancy. Maternal psychosocial problems independently predicted hostile aggressions in preschool and combined additively with infant attachment security in prediction. Results are discussed in relation to the asymmetry of forward and backward prediction that characterized the findings and in relation to the potential significance of disorganized attachment behavior as a precursor to later maladaptation.  相似文献
