Perceptual learning is the process by which the perceptual system improves its ability to interpret sensory information through experience or training. This academic concept investigates the mechanisms underlying enhancements in sensory discrimination, feature extraction, and pattern recognition, which are characterized by long-lasting, often stimulus-specific, changes in perceptual performance. Its significance lies in demonstrating the plasticity of sensory processing and its fundamental role in acquiring expertise and adapting to environmental demands.
