Thus it is logical to assume that additional advances into the understanding of the biological functioning of the human organism and its consequent effects on behaviour will only come about by further application of such procedures. Invasive techniques on animals should still continue with no modifications as long as psychologists abide by all laws governing their application, for they have been set down as to minimise pain and suffering, deemed appropriate in the society that we live that it is by the application of such techniques that both humans and animals will benefit in having a greater understanding into how they function and behave.…
