摘要:

Abstract5‐Hydroxytrypotophan at a dose of 50 mg/kg intraperitoneally (i.p.) sharply increased neural serotonin (5‐HT) levels in mink and considerably inhibited that animal's predatory attack on rats. Intraperitoneal injection of 5‐HT (10 and 20 mg/kg) did not influence such rat‐killing. Neural levels of 5‐HT or 5‐hydroxyindoleacetic acid (5‐HIAA) and subsequent aggression by the predator did not change to any great degree after ingestion of a single meal. Abundance of natural mink food for 3 days was associated with an increased level of 5‐HIAA in the lateral hypothalamus and the amygdala as well as with an increased latency to attack and to kill rats. 5‐HT seems to represent an endogenous factor that inhibits predatory attack by the mink; this effect appears to function through increased metabolism of 5‐HT in some brain regions, which is evident after abundant intake of tryptophan wi

摘要:

AbstractPlay‐fighting appears to involve the behavior patterns of attack and defense otherwise seen in serious fighting. The degree of similarity, however, depends on the body targets attacked and defended during these forms of fighting. For many taxa, including diverse mammalian families and some birds, the same targets are attacked and defended during both play‐fighting and serious fighting. However, for several species of muroid rodents, the targets of play‐fighting are not the same as those of serious fighting. In these cases, the tactics of attack and defense are also different. It is argued that for these muroid species the playful targets have arisen from amicable behavior (e.g., social investigation, greeting, allogrooming) rather than, as appears to be the case in so many other taxa, from agonistic behavior. These data strongly suggest that “play‐fighting” has evolved from different precursors in different taxa and thus has multiple origins. Furthermore, these data have an important bearing on the universal applicability of many of the suggested functions of play‐fighting and also on how such behavior is to be described a

摘要:

AbstractThis research delineates several factors that may affect how likely observers are to judge some international actions as aggressive. Subjects rated scenarios in which a country intercedes in the affairs of another country experiencing internal or external difficulties. Judged to be more aggressive, as hypothesized, were actions in which it was “they” rather than “we” who were responsible, actions capable of causing injury or death, and actions carried out for a country's own self‐interest. There were also unpredicted subtleties of judging international behavior. The results are considered from the perspective of recent contextualist t
