Novelty-induced grooming was studied in aged male rats (24 months old) compared to young animals (3 months old). When put in a novel environment, aged rats exhibited a grooming activity markedly higher than that shown by young rats. Such an excessive grooming did not disappear over a 30 min observation. Furthermore, no significant difference between old and young rats was found in ambulation, rearing and defecation, as observed in an open field. It may be suggested that increased grooming activity in aged rats involves a disability to adapt to a novel environmental situation.
将老年雄性大鼠（24个月大）与幼年动物（3个月大）进行比较，研究了新奇诱导的梳理行为。当置于新环境中时，老年大鼠表现出的梳理活动明显高于幼年大鼠。在30分钟的观察期内，这种过度梳理行为并未消失。此外，在旷场试验中观察到，老年大鼠和幼年大鼠在行走、直立和排便方面没有显著差异。可以推测，老年大鼠梳理活动的增加涉及到适应新环境情况的能力缺陷。
