The term "perceptual learning" has different meanings for different psychologists. Some view it as the idea that human perception is largely learned, such as learning to see depth or form. This leads to a debate between nativism and empiricism. Others see it as learning through perception, involving comprehension, expectation, or insight, which is a cognitive process rather than a motor one. This leads to a debate about whether one must study a person's perceptions to understand their behavior. The paper focuses on the question of how we learn to perceive. It discusses the philosophical roots of this question and the theories that have been proposed to explain the discrepancy between sensory input and perception. These theories include rationalism, nativism, and empiricism, which suggest that knowledge comes from the mind, innate ideas, or past experience. The paper also discusses the theory of sensory organization, which suggests that perception is structured rather than learned. The paper argues that both the role of learning in perception and the role of perception in learning are important. It presents two theories of perceptual learning: one that views learning as enriching previously meager sensations, and another that views learning as differentiating previously vague impressions. The paper concludes that both theories have merit and that the distinction between them is not clear-cut. It suggests that perceptual learning involves the development of specific responses to stimuli, and that this process is not necessarily dependent on past experience. The paper also presents an experiment that illustrates this learning process, showing how participants learned to identify specific stimuli through repeated exposure. The results of the experiment support the idea that perceptual learning involves the development of specific responses to stimuli, and that this process is not necessarily dependent on past experience. The paper concludes that the relationship between learning and perception is complex and that both are important in the development of perceptual skills.The term "perceptual learning" has different meanings for different psychologists.
