Psychology This study measured behaviors of three strains of inbred mice (C3H/FeJ, C57/BL6J, DBA/2J) under conditions of regular, repeated separation of mother from young accompanied by adoption of young by one of the other mothers. There were five groups which were reared in the following manner: C - mother and pups stayed together from birth to weaning day; E1- from day one to weaning, the pups were rotated daily to a cage occupied by one of the mothers from another strain, and back to their own mother every third day; E2 - from day one to weaning, the mothers were rotated daily to the cage occupied by a litter of another strain, and back to their own pups every third day; E3 - and E4 - treated as in Groups E1 and E2, respectively, except that the rotations were done within the same strain. Litter weight, nest location and condition, the latency to retrieve pups and/or the latency of pups to locomote to the nest, and developmental variables were recorded daily for all groups. In addition, litter weight and open-field behavior were measured at days 21, 31, and 41; at day 22 a postweaning test was- of the number of five-second periods spent by the pup in proximity to different females, and the number of squares over which the pup was observed to be following those females. Strain and Days were the important factors in the pups' litter weight gain, latency to locomote to the nest, and open-field behaviors; the rotation procedure did not affect the pups' development. Rotation effects were strongest in the behavior of the mothers that were rotated to a strange cage each day (Groups E2 and E4), as shown by the significantly higher latencies of these mothers to retrieve the pups, and by their practice of moving the nest significantly more often and keeping it in better condition than in the other groups. Postweaning test of Proximity and Following indicated that rotation of either pups or mothers affected these scores in the pups: Group C pups scored highest with their biological mother, Groups E1 -E4 chose all adult females about equally, with Groups E1 and E3 scoring lower than the other groups. The feasibility of this design as a model of human cooperative childrearing, and differences between the present results and those of other experimental rearing studies with rodents, are discussed. 1975 English text Bowling Green State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1566297715173503 http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1566297715173503 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
