" The restriction of studies of human intellect and character to studies of conscious states was not without influence on a scientific studies of animal psychology. "
- Edward Thorndike

When discussing human intellect and character, there was a tendency to focus solely on conscious states and experiences. This approach had an impact on how scientists studied animal psychology as well. By limiting the study of human cognition to what individuals are aware of, it narrowed the scope for understanding both humans and animals more comprehensively.

The deeper implication of this quote lies in recognizing the limitations imposed by a narrow focus on consciousness when studying complex behaviors and mental processes, whether in humans or other animals. Edward Thorndike’s observation suggests that confining studies to what is consciously experienced overlooks unconscious influences and underlying mechanisms, which are crucial for a holistic understanding of intelligence and behavior. This restriction not only affects the study of human psychology but also hinders the scientific exploration of animal behavior by ignoring subconscious processes that significantly contribute to their actions.

Edward Thorndike was an influential American psychologist who contributed extensively to the fields of educational psychology and behavioral analysis. His work laid important groundwork for modern theories on learning, intelligence, and motivation. Among his many notable contributions is the Law of Effect, which posits that behaviors followed by satisfying consequences are more likely to be repeated in the future. Thorndike's insights have had a lasting impact on how we understand both human and animal behavior.
