The effects of daily trimming of the whiskers in rat pups from day 2 or day 9 to day 20 on eye opening time and the formation of early behavioral reactions, i.e., walking, rearing, grooming, and manipulatory activity, were studied in rat pups subjected to deprivation and siblings reared with them. Rat pups subjected to vibrissectomy from day 2 of life and their siblings showed acceleration of eye opening, maturation of grooming, and rearing without support; the formation of manipulatory activity was delayed, as were changes in the structures of correlational relationships between the times at which behavioral reactions formed and eye opening occurred. Vibrissectomy from day 9 of life eliminated most correlational relationships in deprived animals without impairing the dynamics of the development of early behavioral reactions. Siblings showed delayed formation of manipulatory activity, though changes in the structure of correlational relationships were less significant than in deprived animals.
研究了从出生第2天或第9天到第20天每天修剪幼鼠胡须对睁眼时间以及早期行为反应（即行走、站立、梳理毛发和操控活动）形成的影响，实验对象为经历胡须切除的幼鼠及其一同饲养的同胞幼鼠。出生第2天接受胡须切除的幼鼠及其同胞幼鼠表现出睁眼加速、梳理毛发成熟以及无需支撑就能站立；操控活动的形成延迟，行为反应形成时间与睁眼时间之间的相关关系结构变化也延迟。出生第9天进行胡须切除消除了剥夺组动物的大多数相关关系，但不影响早期行为反应的发育动态。同胞幼鼠表现出操控活动形成延迟，不过相关关系结构的变化不如剥夺组动物显著。
