The influence of competitive status (winner/loser) on the behavior of male rats in three models of anxiety

Studies indicate that features such as prior stressful experience, strain, gender, and age can influence the behavior of rats in animal models of anxiety. In the present study, we examined the possible influence of competitive status (winner/loser) in three such models: the elevated plus‐maze, the open field, and the social interaction test. One hundred to 135‐day‐old male Wistar rats were conditioned to traverse a straight runway tube to obtain food. Subsequently, two rats were placed at the same time in the runway tube and, being unable to pass each other, one of them pushed the other to the opposite end‐box. The rats were categorized as winners or losers in this competition. One week after the straight runway tube test, the rats were submitted to the anxiety models, where it was observed that winner rats showed greater locomotor activity than the losers in the three models studied. Furthermore, winner rats showed less immobility and higher central and total locomotor activity in the open field and a greater duration of social interaction in the social interaction test. These results suggest that competitive status has an influence on the locomotor activity of rats in animal models of anxiety. However, whether competitive status influences anxiety as assessed in these models is unclear, and further investigations are warranted. Aggr. Behav. 28:164–171, 2002. © 2002 Wiley‐Liss, Inc.     

Quasi‐Experimental Single‐Subject Design: Comparing Seeking Safety and Canine‐Assisted Therapy Interventions Among Mentally Ill Female Inmates

This repeated measures quasi‐experimental study evaluated the effectiveness of 2 interventions, Seeking Safety and canine‐assisted therapy, with female prisoners with trauma histories on a mental health unit. Results indicate both are effective at reducing anxiety, depression, and posttraumatic stress disorder.     

Protection of animal research subjects

The use of experimental animals, mostly rodents, in biomedical research and especially in oncology and immunology should be acknowledged with respect, recognizing the contribution of animal experimentation in the fascinating scientific progress in these disciplines of research. It is an obligation of the investigator to justify the scientific and ethical aspects of each study requiring the use of animals. The international guiding principles for using animals in biomedical research are well defined and have been distributed worldwide by the International Council for Laboratory Animal Science (ICLAS) since 1956, when this Organization was founded. In Poland the ICLAS philosophy and principles are highly respected and were implemented firstly by the members of the Commission on Biology of Experimental Animals appointed in 1962 by the Department of Medical Science of the Polish Academy of Science in Warsaw. Animal Protection Acts, first proclaimed in 1928 were gradually modified and improved. Actual legislation (enacted in 1997, 2003 and 2005) is consistent with EU Directives (86/609/EEC) and follows the internationally recommended principles that include ICLAS guidelines concerning animal welfare and care condition in biomedical research. The problem of “alternative methods” is briefly discussed.

Reasonable Partiality and Animal Ethics

Moral psychology is often ignored in ethical theory, making applied ethics difficult to achieve in practice. This is particularly true in the new field of animal ethics. One key feature of moral psychology is recognition of the moral primacy of those with whom we enjoy relationships of love and friendship – philia in Aristotles term. Although a radically new ethic for animal treatment is emerging in society, its full expression is severely limited by our exploitative uses of animals. At this historical moment, only the animals with whom we enjoy philia – companion animals – can be treated with unrestricted moral concern. This ought to be accomplished, both for its own sake and as an ideal model for the future evolution of animal ethics.     

Doing Right by Our Animal Companions

The philosophical literature on the moral status of nonhuman animals, which is bounteous, diverse, and sophisticated, contains a glaring omission. There is little discussion of human responsibilities to companion animals, such as dogs and cats. The assumption seems to be that animals are an undifferentiated mass – that whatever responsibilities one has to any animal are had to all animals. It is significant that we do not think this way about humans. Most of us (all but extreme impartialists) acknowledge the existence of special responsibilities to humans. We believe, for instance, that our children, friends, and compatriots have special claims on our attention, time, energy, and resources. This is not at all incompatible (although it is sometimes thought to be) with the view that we have obligations to strangers. My aim in this essay is to fill the lacuna in the literature. I argue that the act of taking an animal into one's life or home, through purchase, gift, or adoption, generates responsibilities to it, the main one being to provide for its needs, which, in the case of dogs (for example), are many and varied. Since this thesis is shrouded in misconception, I devote part of the essay to clarifying it. I then diagnose its philosophical neglect, which stems from both practical concerns and theoretical commitments. I argue that the practical concerns are groundless and that the theoretical commitments do not have the implications they are thought to have.     

Family of the forest: Fatal enmeshment and other systems issues in the animal world

While the observation of non-human animal behavior has been a major means of developing psychological theories, it has been rarely used by marriage and family therapists to devise or explain systemic ideas. Jane Goodall's multigenerational research on the Flo family of wild chimpanzees in Gombe, Tanzania, as presented in her own and other's writing, and especially in Hugo van Lawick's documentary film,People of the Forest, offers a clear example of how systems concepts' application to animal families may have theoretical, pedagogical, and clinical utility.My thanks to my good friend, Violet Richman, who suggested the subject for this paper.
