Devaluation As A Strategy To Address Behaviourally Whether Fish Feel, Robert Ian Bowers
Animal Sentience
Failures of behavioural studies to address the question of whether fish feel pain have left scientists arguing on the basis of other criteria, including anatomy. I draw an analogy with a debate concerning the breadth of stimulus-response learning among nonhuman animals and propose an experiment that harks back to one solution to that debate: the devaluation paradigm. By changing the value of a noxious stimulus after training, one can differentiate a directly evoked response from a response to an intermediate representation, the pain.

How Animals Grieve is beautifully written, but it intermixes examples meeting King’s criteria for evidence of grief with other poignant but far less convincing examples. Yet, as noted earlier by Griffin (1958/1974), “Excessive caution can sometimes lead one as far astray as rash enthusiasm.” King cites strong evidence from long-term scientific field studies, often involving known individuals; from videotapes; from convergent evidence in neurophysiological studies; and, notwithstanding possible emotional bias, from animals living closely with humans. …
