BPS Guidelines for Psychologists working with animals-2007 link
According to the American Psychological Association about 8% of psychological research involves the use of animals; this is most likely to be in the USA. • A number of species are used. • Around 90% of which are rodents and birds, mainly rats, mice and pigeons. • Only around 5% of the animals are primates; cats and dogs are studied rarely.
Do the ends ever justify the means? Each person will have their own views on this. Is the animal suffering caused by certain types of research outweighed by the benefits to humanity? Bateson (1986) expressed this as a 3D graph
Bateson cube Draw this on p18 of your Biological Pack
The cube has 3 axes measuring suffering, certainty of benefit and quality of research. • If the research is high quality, certain to be beneficial and not going to inflict suffering then it will fall into the hollow section (top front) meaning research should proceed. • Painful, low quality research with lower likelihood of success will be bottom back in the solid and should not proceed. • Most research will not be clear cut but the rule is solid should not continue, hollow should. • The problem of course is how to determine benefit in advance. Also who will decide on quality of research and the level of suffering? Both of which are subjective measures.
Many scientists believe that using animals for research purposes is completely justifiable YESNO NOT EVERYONE AGREES WITH THIS HOWEVER
The 3 Rs • Replacement of animals by other methods such as computer models and simulations. 2. Reduction in the number of animals used. More advanced statistical methods can be used allowing significant results based on lower numbers. Sharing of information between institutions allows the number of replications to be reduced. 3. Refinement of experimental methods to inflict less pain and suffering.
BPS Guidelines for Psychologists working with animals-2007 States: Psychologists must adhere to the legal requirements of the country they are working in. Psychologists have to be aware of endangered species or threatened species and act appropriately. Research must be prefaced with a covering letter stating this.
Replacing use of animals Videos and computer simulations have to be used where possible. Ideal for teaching situations. e.g. Ratlife and Sniffy the Rat
BPS Guidelines for Psychologists working with animals-2007 • Choice of species and strain Species should be carefully chosen to ensure effectiveness with minimal suffering-knowledge of species and history of individual animals vital Choices have to be justified on project licence application Different strains of rodents are physiologically different and need to be chosen carefully. Transgenic mice may be used as no harm to organism is observed.
BPS Guidelines for Psychologists working with animals-2007 • Number of animals 1986 Act-legally required to use smallest number of animals possible National Centre for 3Rs (Replacement, Refinement and Reduction) can provide advice on how the use of better methodologies/designs and statistical analysis can help achieve this.
BPS Guidelines for Psychologists working with animals-2007 • Procedures Project licence Registered establishment Personal licence Local ethical review process (Committee) Home Office Identify costs to animals in reports/journals
BPS Guidelines for Psychologists working with animals-2007 • Procedures (contd) Housing- caging needs to take into account the social behaviour of species Reward, deprivation, aversive stimulation- periods of deprivation of food should be short and species specific Aggression and predation- natural encounters preferable if staged animals should be protected Fieldwork- should not disturb the ecosystem or interrupt species reproduction and survival Anaesthesia, analgesia and euthanasia- animals should have access to pain relief and be destroyed humanely if suffering
BPS Guidelines for Psychologists working with animals-2007 • Procurement Home Office Designated Breeding and Supply Establishments. Wild caught animals- refer to ASAB website
BPS Guidelines for Psychologists working with animals-2007 • Animal Care Housing and husbandry conditions must be within guidelines Captive animals should be kept in conditions closely resembling their natural conditions as much as possible Need to foster habituation to minimise stress Animal care personnel must be trained
BPS Guidelines for Psychologists working with animals-2007 • Disposing of animals Distribute to other colleagues if deemed possible by home office If disposed of- it must be done humanely Death must be confirmed before disposal Vets must be consulted
BPS Guidelines for Psychologists working with animals-2007 • Animals in psychology teaching Teachers have a responsibility to educate pupils on ethical issues Coursework on animals may be possible but tests to show known facts are prohibited Use of film/video should be encouraged Undergraduates must work within a project licence Post graduates need personal licence
