They discover the genetic underpinnings of affiliative and competitive orientations in addition to the organic correlates of those behaviors. they give thought to environmental variables--family styles, childrearing practices--that impression prosocial and delinquent behaviors. they usually learn inner methods similar to empathy, socio-inferential skills, and cognitive attributions, that keep an eye on "kindness" and "selfishness." the 1st part specializes in organic, sociobiological, and ethological ways. It explores the application of animal versions for figuring out either human and infrahuman social habit. the second one part makes a speciality of the advance, socialization, and mediation of altruism and aggression in young children. numerous matters underly either sections. those comprise the function of attachment tactics, separation misery, reciprocal interchanges, and social play in selecting the volume and caliber of competitive and affiliative interactions; the functionality of feelings (e.g. empathy, guilt, and anger) as instigators of altruism and aggression; and the character of intercourse alterations. numerous chapters current info on feelings that mediate altruism and aggression and likewise on styles of organization among prosocial and delinquent behaviors. The authors take an ethological point of view, putting detailed value at the have to discover altruism and aggression within the actual lives and usual habitats of people and different animals.

Furthermore, the localization of opiate circuitry appears to be a reasonably good guide in our ongoing search for play circuitry in the brain. Still, considering the intricacies of the underlying neural machinery for any behavior, many of the findings described herein may eventually be subsumed by broader principles such as opioids mediating pleasure or habits in the brain (Panksepp, 1981b). But then, attachments occur not only to kin and other nearby organisms, but also to places and objects, and even to ways of behaving.

Perceptually induced resonance of emotive circuits between nearby animals), emotional brain systems may evoke contagious interanimal mood states from which altruistic behaviors arise. For instance, pain responses in one animal may unconditionally activate distress circuits in brains of nearby animals, promoting behaviors that minimize distress in both. Such seeking of emotional relief may have direct survival value for the recipient and indirect (genetic) survival value for the altruist. However, the proximal underlying mechanism is presumably related to the rebalancing of activity in emotional circuits, and only in a distal sense may such behavior also help keep the genetic ledger in the black.

However, as far as maternal behavior is concerned, neither decortication (Murphy, MacLean, & Hamilton, 1981) nor hypophysectomy (Lamb, 1975) markedly disrupts maternal behaviors (although lactation is compromised by the latter manipulation), suggesting 46 J. PANKSEPP that the limbic lesion effects observed are probably due to direct effects on maternal behavior control circuits. Septal lesions seriously disrupt all aspects of maternal behavior (Carlson & Thomas, 1968; Slotnick & Nigrosh, 1975), and similar defects have been observed in animals with hippocampal damage (Kimble, Rogers & Hedrickson, 1967).
