ABSTRACT
Physically maltreated children are at risk for developing externalizing behavioral problems characterized by reactive aggression. The current experiment tested the relationships between individual differences in a neural index of social information processing, histories of child maltreatment, child negative affect, and aggressive behavior. Fifty boys (17 maltreated) performed an emotion recognition task while the P3b component of the event-related potential was recorded to index attention allocation to angry faces. Children then participated in a peer-directed aggression task. Negative affect was measured by recording facial electromyography, and aggression was indexed by the feedback that children provided to a putative peer. Physically maltreated children exhibited greater negative affect and more aggressive behavior, compared to nonmaltreated children, and this relationship was mediated by children's allocation of attention to angry faces. These data suggest that physical maltreatment leads to inappropriate regulation of both negative affect and aggression, which likely place maltreated children at increased risk for the development and maintenance of externalizing behavior disorders.

The current study evaluated the quality of facial and vocal emotional expressions in abusive and non-abusive mothers, and assessed whether mothers' emotional expression quality was related to their children's cognitive processing of emotion and behavioural problems. Relative to non-abusive mothers, abusive mothers produced less prototypical angry facial expressions, and less prototypical angry, happy, and sad vocal expressions. The intensity of mothers' facial and vocal expressions of anger was related to their children's externalising and internalising symptoms. Additionally, children's cognitive processing of their mothers' angry faces was related to the quality of mothers' facial expressions. Results are discussed with respect to the impact of early emotional learning environments on children's socioemotional development and risk for psychopathology.
ABSTRACT
Two experiments using event-related potentials (ERPs) examined the extent to which early traumatic experiences affect children's ability to regulate voluntary and involuntary attention to threat. The authors presented physically abused and nonabused comparison children with conflicting auditory and visual emotion cues, posed by children's mothers or a stranger, to examine the effect of emotion, modality, and poser familiarity on attention regulation. Relative to controls, abused children overattended to task-relevant visual and auditory anger cues. They also attended more to task-irrelevant auditory anger cues. Furthermore, the degree of attention allocated to threat statistically mediated the relationship between physical abuse and child-reported anxiety. These findings indicate that extreme emotional experiences may promote vulnerability for anxiety by influencing the development of attention regulation abilities.

The impact of 2 types of learning experiences on children's perception of multimodal emotion cues was examined. Children (aged 7-12 years) were presented with conflicting facial and vocal emotions. The effects of familiarity were tested by varying whether emotions were presented by familiar or unfamiliar adults. The salience of particular emotional expressions was tested by contrasting the performance of physically abused and nonabused children. Children exhibited a preference for auditory expressions produced by their mothers but not by strangers. Additionally, abused children were biased to rely on auditory cues when their own abusive mother was expressing anger. These results are discussed in terms of the impact of both typical and atypical early experiences on the development of emotion perception.
