“…These groups are also most differen t from the control-control group. Such a "c ontrast" effect appears to be fully in agreement with the suggestion put forward by Fuller and Clark (1966) that the effects produced in dogs by restricted early experience may be mainly due to the trauma of emerging from one kind of environm ent and ente ring anothe r that is strikingly different. In the present study, the analogous contrast would lie in the transition from occupying a "quiet" uterine environment to rearing by an " active" mother and vice versa.…”

Female rats were exposed during pregnancy either to enriched, restricted, or normal cage environments. At parturition, complete crossfostering of litters was carried out. Prenatal maternal treatment affected open-field scores both of biological and foster offspring. Largest effects were obtained for (a) offspring born of enriched mothers and reared by restricted mothers ; and (b) offspring born of restricted mothers and reared by enriched mothers. Activity scores of the mothers themselves showed no effects of the pregnancy treatments.

“…With varying degrees of social isolation, particularly during the critical period for socialisation (4-12 weeks of age), dogs are likely to develop maladaptive behaviours such as kennel dog syndrome (Scott and Fuller, 1965 ) or the more severe isolation syndrome (Fuller and Clark, 1966 ). It has also been shown that dogs' activity patterns are strongly influenced by the presence of humans (Neamand et al, 1975: Hughes andCampbell, 1990).…”

Behaviours studied were movement, vocalisation, lying down, sleep, object manipulation, barrier manipulation, barrier jumping, fence running, agonistic and affiliative activities, and proximity. Behavioural effects were compared among housing conditions, order of rotation through each housing condition, and behavioural changes over time during each 3 month rotation.Dogs spent more time moving in pens and runs than in cages. Dogs housed in the greatest degree of social isolation spent the most time moving, exhibited the greatest number of bizarre movements, and vocalised the most. Dogs housed in the smallest cages spent more time grooming and in manipulation of enclosure barriers than those housed in any other conditions. Forced treadmill exercise did not significantly alter behaviours. When housed in pairs, dogs spent more time sleeping and showed a tendency to spend less time vocalising than when housed singly.The results indicate that spatial area and activity are not likely to be the most important factors to be considered when evaluating psychosocial well-being of dogs. In assessing the psychosocial wellbeing of dogs, social isolation may be as harmful or more harmful than spatial restriction.

“…Although the reasons for the species difference i n results are unknown, it is obvious that the influence of early experience, e.g., AMPH treatment, on adult behavior varies with the genetic background of the animals tested. This generalization is supported by the efforts of several workers including Fuller and Clark (1966), who reported that early isolation affects the adult behavior of two breeds of dogs in a differential manner; Levine and Broadhurst (1963), who found that the effect of controlled infantile stimulation on adult performance varies considerably in two strains of rats that show genetic differences in emotionality; and Winston (1963), who demonstrated that hereditary factors and infantile experience have an important influence on learning in adult mice.…”

WOLF, HAROLD H., and ROWLAND, CLAYTON R. (1969). fiflects oj Chronic Postnatal Drug Administration on AdultDominance Behavior in Two Genera of Mice. DEVELOPMENTAL PSYCHOBIOLOGY, 2(4): [195][196][197][198][199][200][201]. T h e experiments described examine the influence of early chronic treatment with amphetamine (AMPH) or chlorpromazine (CPZ) on the formation of adult dominance behavior in two genera of mice, i.e., Peromyscus rnaniculatrcs bairdi and a random bred, Swiss albino strain of Mus rnusculus. It was found that AMPH-pretreated Swiss albinos were significantly more dominant than either CPZ-pretreated or control animals. Early drug treatment had little effect on dominance behavior of adult bairdi. These results indicate that chronic administration of certain drugs to young animals is capable of producing a quantitative change in the formation of adult behavioral patterns. Moreover, the degree to which early drug treatment alters adult behavior is influenced by the genetic background of the organism. Investigators in the area have examined the influence of a variety of types of early experience including degree of social interaction, food deprivation, handling, pain, and numerous other environmental manipulations. There is, however, a relative paucity of information describing the effects of drugs, as a means of altering early experience, on adult behavioral patterns. That drug administration in infancy can have a marked influence on the behavior of mature organisms has been demonstrated by Meier and Huff (1962), Doty and Doty (1963), Heimstra and Sallee (1965), and recently by Gauron and Rowly (1968), andUehling (1969). These authors have shown that, in rats, early chronic administration of a variety of centrally acting drugs, e.g., chlorpromazine, reserpine, deanol, thioridazine, amphetamine, etc., leads to pronounced and persistent effects on many adult behaviors including degree of emotionality, dominance, discrimination, and adaptive problem-solving activities.
