The goal of the present study was to explore the social behaviours of inhibited children in familiar social contexts, including: (1) free play with peers at preschool and (2) social activities at home and in the community. The initial participants were N =248 preschool children between the ages of 42 and 66 months. From this initial data, two smaller groups of inhibited (N =12) and uninhibited comparison (N =12) children were identified. These children were observed during free play at preschool and parents completed daily logs of children's social activities outside of school. Among the findings, inhibited children were observed to display more reticent (on looking, unoccupied) and anxious behaviours during free play preschool than uninhibited children. As well, inhibited children participated less in structured social activities outside school and were more likely to engage in dyadic play at home with a single friend as compared to their uninhibited counterparts. 相似文献

Two experiments investigated some of the factors that influence food hoarding behaviour in the golden hamster (Mesocricetus auratus). In Experiment 1, hamsters given limited access to food failed to increase the amount of food they consumed at each meal. Instead, they exhibited a significant increase in the amount of food taken to hoard during the limited access period, and this permitted hamsters who were allowed to retain their hoard to maintain body weight at levels comparable to free-feeding controls. Hamsters that were not allowed to retain hoarded food rapidly lost body weight. There was also an inverse correlation between body weight and amount of food taken to hoard in all hamsters given limited access to food, suggesting that body weight loss was one factor directly related to increased hoarding during periods of limited food accessibility. Experiment 2 investigated the effect of hoard-size discrimination on food hoarding in hamsters by artificially manipulating hoard size. The results suggested that hoarding behaviour could be influenced by artificially depleting and repleting the hoard, and this factor appears to influence hoarding in the absence of any significant changes in body weight. These results are discussed in relation to the kinds of adaptive feeding strategies that hamsters may utilize in their natural environment. 相似文献
