“Studies such as Harlow’s infamous experiments with infant rhesus macaques, and more modern preference tests, have clearly shown us that our assumptions of what an animal would prioritise or choose in any given situation can often be wrong. Legislation often ensure that the basic needs of animals, such as food, shelter and medical care are considered, but when it comes to the psychological needs of animals this of often a last thought. There is a strong need to fully understand how animals are motivated, and what they are capable of understanding and feeling, so that their welfare can be improved beyond the provision for their basic needs.” Helen Proctor
