Abstract

It has been suggested that naive isolated rats show more "fear responses" than group-housed controls. However, in contrast to previous studies, dark conditions and low noise levels were used to evaluate the latency to emerge from a small chamber into an open field and the subsequent ambulation and rearing behaviour of isolated and group-housed rats. The prediction that these conditions would be conducive to the rapid development of hyperactivity in isolates was confirmed, but there were no significant differences in emergence latency.

摘要

有人认为，未经接触的隔离饲养大鼠比群居对照大鼠表现出更多的“恐惧反应”。然而，与之前的研究不同，本研究采用黑暗环境和低噪音水平来评估隔离饲养和群居大鼠从小室进入旷场的潜伏期，以及随后的行走和站立行为。研究证实了这些条件有利于隔离饲养大鼠快速出现多动的预测，但在出现潜伏期方面没有显著差异。
