“…Therefore, the effect of isolation might instead depend on the subjects' age while they were isolated: If isolation during the postweaning stage increases rats' reactivity while that during the postmaturity stage decreases it, these two effects should offset each other in subjects isolated for 12 weeks. This same question can be found in other studies (Archer, 1969;Coudereau et al, 1997;Korn & Moyer, 1968;Paulus et al, 1998).…”

Using rats as subjects, the effects of a period of isolation and the subjects' age during isolation on the response to foot shock were systematically examined in three experiments. Both the thresholds of shock that evoked a jumping response and that evoked a thrashing response were measured. The results suggest that the threshold for jumping response decreased when rats were isolated during the postweaning stage of development. On the other hand, the threshold for thrashing response decreased when the subjects were isolated for more than 39 days, independently of their age during isolation. Possible causes of the differential effects of these two factors are discussed in relation to the developmental process of these two behavioral indices.

“…In accord with this prediction, isolatehoused chicks and ducks were silent and froze longer in the open field than their group-housed counterparts . Similar results have been reported for rodents (Ader, 1965;Berg, Shanin, & Hull, 1975;Korn & Moyer, 1968;Thiessen, 1963). Another method of varying social motivation is to test animals in an open field individually or in pairs.…”

“…Korn and Moyer (1968) found that individually housed Sprague-Dawley rats of either sex were less active than group-housed counterparts; Archer (1969) reported a similar result only for female Wistar rats, there being no ambulation differences in male differentially housed rats. The influence of sex variables was therefore also examined in this study.…”

Previous comparisons of the activity differences of individually and group-housed rats have produced inconsistent findings; therefore, we examined activity using three measures: openfield ambulation, nonspecific circadian activity, and rearing behavior. Open-field ambulation in two 5·day tests confirmed our prediction that isolates would be initially less active but later more active than group·housed rats. Isolates habituated more slowly to the activity monitor and tended to be more active during the light half of the 24·h cycle. In the rearing test, isolates showed elevated and more persistent activity than group-housed rats. All these activity differences were prevalent in both male and female rats. The results are interpreted in terms of the influence of differential housing on "fear responses," exploration of a novel environment, and differences in habituation/adaptation processes.
