Conflict behaviors of maltreated and nonmaltreated children

Maltreated and nonmaltreated children (ages 3–7 years) were paired for brief play sessions involving a single desirable object. Facial, verbal, and physical actions used while negotiating access to the object were examined. Results showed that the maltreated-nonmaltreated pairs were able to engage in a negotiation process resulting in approximately equal sharing of the object. The differences found between maltreated and nonmaltreated children primarily suggested that maltreated children were somewhat hesitant to engage their partners. Results also showed that children's scores on a facial expression recognition task predicted greater responsiveness to their partners' indication of reluctance to relinquish the object.

Electrodermal responses in patients with unilateral brain damage.

Skin conductance responses (SCR) to emotional and to nonemotional stimuli were measured in 16 right and 16 left unilateral brain-damaged patients. Replicating findings by Morrow, Vrtunski, Kim and Boller (1981), those patients with a lesion in the left hemisphere showed higher SCR's to emotional than to nonemotional stimuli while those with a right lesion showed no difference between them. This pattern of results remained when variance in performance on a Facial Expression Recognition task was partialled out, suggesting that the absence of differentiated arousal in right-brain-damaged patients is unrelated to their impairment in perceptual analysis.
