Abstract：
:During the 20th century there has been considerable progress in the study of animal cognition, based on essential ideas that were developed earlier. These essential ideas include the metaphors of the animal, the questions, the sources of hypotheses, and the types of explanations. The progress cannot be generally characterized as continuous improvement, cyclic changes, or discrete steps, but the quality of the empirical results has increased substantially since the first experiments in the field. Improvements in research methods have been primarily responsible for this progress. These have included improvements in animal husbandry, stimulus control, apparatus design, the measurement of behavior, experimental procedures, and data analysis. In the last third of the century the computer has led to major improvements in all stages of the research process in animal cognition. Although they have greatly improved the quality of the empirical results, they have not led to a general theory of animal cognition. In the near future the available research methods are likely to lead to further progress in the developments of quantitative theories of animal cognition.
