Reasons for behaviourists to use animals in experiments

• Animals are fairly easy to handle
• In ethical terms experiments can be carried out on animals that cannot be carried out on humans
• Animals can learn something new which is fairly certain they haven't experienced before so learning is testable
• Laboratory studies mean strict controls
• Objectivity can be achieved
• Measurable stimuli and responses can be isolated from other experiences
• Experiments are fairly easy to repeat and cheap
