I would say that one of features that separates human consciousness from animal is the ability override instinctive behavior. A human infant will jerk its hand away from a hot surface. An older child you can communicate with at the basic level may not although experimenting with this is no doubt unethical. An adult can consciously overcome this instinct.
Are there experiments testing this idea with animals? In animals that science claims are self-aware, it would be interesting to know if they can overcome the automatic reaction to negative instincts.
The first step would possibly be to see if one negative instinct can be overcome in the presence of another. Like will a really hungry chimp walk across a painfully hot surface to reach food? This seems likely but I am unaware of any such testing.
A more interesting example will would be cases of real animal altruism. Science is quick to tout what some call animal altruism as hardcoded and evolving genetically e.g. lions defending prides, mothers defending young. And I agree this can be hardcoded and genetic since I am not aware of lions NOT defending prides or mothers leaving young to predators.
However, these links show cases of what some may call true animal altruism.
