Animal trainers working in scent detection programs are responsible for arranging training contingencies as well as for observing and recording animal behavior. We provided behavioral skills training (BST) to animal trainers working with scent detection rats to improve the treatment integrity of scent‐detection research sessions. We evaluated the trainers' behavior at baseline and during the sequential introduction of each component of BST (instructions, modeling, and feedback). We observed incremental improvements in treatment integrity with the introduction of each BST component. Posttraining probes revealed that these improvements were sustained at least 3 weeks post‐BST. As the trainers' behavior was modified during BST, we observed decrements in measures of rat performance. We discuss the nature of these interactions and their implications for the use of BST in scent detection research and in situations in which intervention with one party produces concomitant effects on the behavior of another. 相似文献

Stronger beliefs in human supremacy over animals, and stronger perceived threat posed by vegetarianism to traditional practices, are associated with stronger speciesism and more meat consumption. Both variables might also be implicated in the moral exclusion of animals. We tested this potential in a 16-month longitudinal study in the USA (N = 219). Human supremacy showed longitudinal effects on the moral exclusion of all animals. Vegetarianism threat only predicted moral exclusion of food animals (e.g., cows and pigs), and, unexpectedly, appealing wild animals (e.g., chimps and dolphins). These findings demonstrate the importance of both human supremacy and perceived threat in explaining moral exclusion of animals and highlight potential paradoxical negative consequences of the rise of vegetarianism. 相似文献

Twenty domestic horses (Equus caballus) were tested for their ability to rely on different human gesticular cues in a two-way object choice task. An experimenter hid food under one of two bowls and after baiting, indicated the location of the food to the subjects by using one of four different cues. Horses could locate the hidden reward on the basis of the distal dynamic-sustained, proximal momentary and proximal dynamic-sustained pointing gestures but failed to perform above chance level when the experimenter performed a distal momentary pointing gesture. The results revealed that horses could rely spontaneously on those cues that could have a stimulus or local enhancement effect, but the possible comprehension of the distal momentary pointing remained unclear. The results are discussed with reference to the involvement of various factors such as predisposition to read human visual cues, the effect of domestication and extensive social experience and the nature of the gesture used by the experimenter in comparative investigations. 相似文献

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. 相似文献

焦虑和抑郁动物模型的研究方法和策略 总被引:13,自引:2,他引:13
焦虑和抑郁障碍是严重威胁人们健康的精神疾病。焦虑和抑郁动物模型是通过一定的心理社会应激使动物产生明显的焦虑和抑郁情绪,模拟人类焦虑和抑郁障碍,以探讨其细胞、分子和基因水平机制。情绪障碍动物模型通常通过表面效度、结构效度和预测效度进行评价。目前的动物模型虽然存在一定的缺点,但已经为临床和科研提供了巨大帮助。 相似文献

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. 相似文献

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.
