A sociocultural psychology of repeated mobility: dialogical challenges / Una psicología sociocultural de la movilidad repetida: desafíos dialógicos

Abstract

In this paper, we propose a sociocultural psychology of the lifecourse to examine the extreme case of families living in repeated international mobility. In this case, mobility is motivated by work, which leads to repeated relocation of housing and occupational arrangements across countries. Based on fieldwork, we highlight three challenges of repeated mobility and discuss their implications within sociocultural psychology.     

Research and Reflection: Animal‐Assisted Therapy in Mental Health Settings

Although animals have been historically associated with promoting physical and mental health benefits for humans, only recently has there been support for such claims in the literature. This article is a preliminary attempt to bring together scientific studies and anecdotal reports that provide evidence of the benefits of using animals in particular counseling situations.     

Food hoarding behaviour in the golden hamster (Mesocricetus auratus): Effects of body weight loss and hoard-size discrimination

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.
