Age-related trends of stroop-like interference in animal size tests in 5- to 12-year-old children and young adults

Few studies have examined the development of Prepotent Response Inhibition (Nigg's interference control) from childhood to adulthood. This cross-sectional study examined differences in Prepotent Response Inhibition among children of 5 age groups: twenty 5- to 6-year-olds, twenty-one 7- to 8-year-olds, twenty-two 9- to 10-year-olds, eighteen 11- to 12-year-olds, and 24 young adults (18- to 24-year-olds). Participants were administered two Stroop-like tasks: the Real Animal Size Test described in 2009 by Catale and Meulemans, which requires that participants decide the real size of animals (big vs. small) displayed in a mismatching pictorial size; and the Pictorial Animal Size Test (an original test), which requires that participants report the pictorial size of the animals. Results showed clear differences between the tests. The Pictorial Animal Size Test elicited robust interference whereas the Real Animal Size Test elicited no interference. The Pictorial Animal Size Test also revealed the development of Prepotent Response Inhibition in children of 5–12 years and between children and young adults. These results were discussed with respect to differences in strengths of processing. The Pictorial Animal Size Test can be a useful tool for assessment of Prepotent Response Inhibition in children older than 5 years of age.

Improved standards for laboratory animals?

In February 1993, Judge Charles R. Richey of the United States District Court issued a summary judgment in the case of Animal Legal Defense Fund, et al. v. The Secretary of Agriculture, et al. The decision, which was in favor of the Animal Legal Defense Fund, requires the U.S. Department of Agriculture to withdraw its current regulations governing exercise for dogs and the psychological well-being of nonhuman primates used for biomedical research and to issue new regulations containing only minimum, measurable standards. Both plaintiffs and defendants contended that they were seeking the best interests of the laboratory animals. The issue at stake is whether animals are better protected if the government establishes limited minimal standards or is allowed to require institutions to provide additional standards, which will be judged on the basis of their effectiveness in maintaining healthy animals. The Court avoided this dispute, however, by placing primary emphasis on applying the Administrative Procedures Act and stating that it was merely interpreting the "plain meaning" of the Animal Welfare Act, as amended. In this article, arguments are presented for interpreting the law in a far more flexible way than Judge Richey did. The conclusion is also reached that there were no winners in the Animal Legal Defense Fund case and that the real losers are the laboratory animals.     

The structure of disgust: domain specificity in relation to contamination ideation and excessive washing

The primary goal of the present study was to employ confirmatory factor analysis to compare two theoretical models regarding the factor structure of disgust (N=307). The two-factor model of Animal Reminder and Core disgust proposed by Rozin et al. (2000) demonstrated superior model fit over a one-factor model that has been implicated in prior research. However, contrary to theoretical predictions, categorizing Hygiene disgust as Core disgust rather than Animal Reminder disgust provided an overall better fit for the two-factor model. The second aim of the study was to investigate the relationship between the empirically derived two-factor model and contamination ideation and excessive washing using structural equation modeling. Findings indicated that the Contamination Ideation and Excessive Washing latent factor was specifically related to Core disgust (domain specific) and negatively related to Animal Reminder disgust. The relevance of these findings in the context of future research investigating the role of disgust in specific anxiety disorders is discussed.

Biodefense research and the U.S. regulatory structure whither nonhuman primate moral standing?

Biodefense and emerging infectious disease animal research aims to avoid or ameliorate human disease and suffering arising from the natural outbreak or intentional deployment of some of the world's most dreaded pathogens. Research to develop medical countermeasures to these diseases faces a difficult challenge since the products usually cannot be tested for efficacy in human beings. The U.S. Food and Drug Administration's Animal Rule may be increasingly used to overcome this challenge by allowing researchers to translate animal data into medical countermeasures without human subject efficacy testing. Yet the Animal Rule also has significant implications for increased intensive nonhuman primate research. We argue that despite the common belief that nonhuman primates have a fairly high level of moral standing and the protections for animals that are crucial to the U.S. regulations guiding animal research, the Animal Rule specifically and the regulations generally raise serious problems for the attribution of moral standing to nonhuman primates. We argue, however, that the burden of proof is on a position denying all moral standing to nonhuman primates and compare the implications of the U.S. regulatory structure in this regard with some recent developments in the European Union.

A Review of Animal Assisted Therapy in Counseling

Panikattacken – mTGT ohne Pharmakotherapie

Only a limited number of medical studies referring to Animal Assisted Therapy have been published worldwide. The specific concept of medically oriented Animal Assisted Therapy (mAAT) was developed by the Austrian Institute for Animal Assisted Therapy & Research (AIAATR), based north of the city of Krems/Donau in Lower Austria, as a nonpharmacological treatment method for patients with mental or psychological overload. This particular case study describes a 30-year-old female academic who had been brought to the institute by her concerned neighbour because of repeated panic attacks. Despite extensive briefing, the patient vehemently refused any pharmacological intervention. Therefore, two-step management starting with an acute phase therapy of two therapeutic units (ThU), 90 min each over 5 days – during this period the patient stayed at the patient appartement of the institute – followed by a regular treatment cycle of 1 ThU/week over 12 weeks was selected. The HAMA-21 was used to evaluate treatment quality, therapy progress, and success. A total score of 30 at the beginning declined to 3 at the end of treatment.

Between ticks and people: Responding to nearbys and contentments

Ticks, their bodies, the affects and emotions they inspire, the diseases they potentially carry, raise questions that are different, though not unrelated, to those concerning the dogs, lab rats, chickens, or wolves more typically encountered in Animal Studies. Engaging with such questions leads us to consider a ‘geography of nearby’ that attends to the spatial, emotional, behavioural, taxonomic, historical, ecological, topographies that tie particular humans and creatures together in particular ways. As an example of how this geography of the nearby infuses material encounters, practices and theories, this paper attends to the way that ethics is framed within the Animal Studies literature. Setting the emotional registers inspired by ticks against those typically adduced in framing ethical responsibilities to other creatures we might come to recognise the politics and ethics of inclusions and exclusions which shape much literature in animal studies. To make such a move is not to criticise or dismiss work within Animal Studies but to demonstrate how the animals we think with shape the theoretical, practical and political consensus we reach. The paper concludes with a move toward ‘contentment’ as a register for encountering ticks.

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. Dr. Donald Boisvert, CCAC — Canadian Council on Animal Care A lecture on the subject of this paper was presented at the 6th International Bioethics Conference entitled ‘The Responsible Conduct of Basic and Clinical Research’, held in Warsaw, Poland, 3–4 June 2005. The author is the National Representative of Polish Academy of Science to the International Council for Laboratory Animal Science (ICLAS) and a Member of the ICLAS Governing Board.
