Sensory Discrimination in Normal, and Feeble Minded Children (Classic Reprint)

Explore how sensory tests reveal true limits of perception in feeble-minded and normal children—and what this means for understanding intelligence.

This scholarly work presents a careful series of experiments on how people discriminate lifted weights, aiming to separate sensory capacity from purely intellectual factors. The study compares feeble-minded individuals with normal peers, using a standardized procedure to establish norms and evaluate whether differences in weight discrimination reflect sensory ability or cognitive factors.

• Learn how the experiment is designed, including how weights are chosen and how judgments are recorded.
• See how defectives and normals perform at different ages, and how intelligence and age relate to sensory discrimination.
• Understand the implications for diagnosing and interpreting sensory tests in light of mental development.
• Get a sense of how findings from this early 20th-century research fit into broader debates about mind and perception.
