Scientific knowledge is acquired through reason, experience. . . and is verifiable, objective and systematic. a Research can meet two key objectives, produce knowledge (basic research) and problem solving (applied research), a siendoa in any way which in part has led to several developments of humanity, as is the case of the method Chest. a Research can meet two key objectives, produce knowledge (basic research) and problem solving (applied research), a siendoa in any way that's partly the various developments originadoa humanity, such as Bunker method, being forced to point out that in order to carry out the establishment of this metodogia and importantea progress, resultabaa need a certain level of competence for research together with the indispensability of certain sensory faculties and essentially innate intellectual, such as a specific special empathy that would allow penetration by observing, analyzing and understanding the most intricate key search dog behavior, critical initial step to deal productively to achieve what was once a patient daunting task of thorough preparation, tending constantly to achieve a positive overall relationship which convoluted puzzle to complete seamlessly with the best possible result. Others including Newark Beth Israel Heart Transplant, offer their opinions as well. Jaime Parejo dissected from the beginning, all existing training systems and involvement of search dogs (French, German, Swiss, American…) noting that basically limited to the simple application of operant conditioning (discovered by Frederic Skinner, based on that conduct positively reinforced tend to be repeated), classical conditioning discovered by Ivan Pavlov, shaping by successive approximations and introducing a greater or lesser extent, during the canine search behavior of certain orders steerable. .
