摘要

近交系C57Bl/6J小鼠在野外行走、饲养、梳洗和排便等方面表现出较大的鼠间差异(变异系数为30% ~ 150%)。这些差异不是随机的，因为在六个月内对相同行为的六次测量是相关的(肯德尔一致性系数在0.37-0.59之间，具有统计学意义);然而，小鼠在六种测量中表现出不同的行为特征(即在某些顺序中出现唯一性)。在所有被测量的行为中，只有行走和养育是相关的;也就是说，它们可能构成一种行为综合症。

Consistent individual differences in some behaviors in mice of the C57Bl/6J inbred strain

Mice of the inbred C57Bl/6J strain displayed considerable inter-mice variation in ambulation, rearing, grooming, and defecation in the open-field (coefficients of variation from 30% to 150%). Those differences were not random, because six measurements of the same behavior, taken along six months, were correlated (Kendall coefficients of concordance were in the range 0.37–0.59 and statistically significant); yet, the mice displayed different behavioral profiles along the six measurements (i.e. uniqueness occurred within some order). Of all the behaviors measured, only ambulation and rearing were correlated; i.e., they may constitute a behavioral syndrome.

期刊介绍： The Anuario de Psicología, one of Spain"s most important general psychology journals, is published by the Faculty of Psychology of the University of Barcelona. It appears three times a year. The Anuario combines continuity with the past with a strong commitment to the present and the future. The journal is broad-ranging, interdisciplinary, and innovative. The Anuario publishes research reports and applied studies in all fields of psychology. We also accept theorical, epistemological studies, organize dossiers on topical themes, and hold debates on controversial subjects deriving from a central article.
