| Description | Papers concerning Francis Galton's investigations on psychometry, the study of people's mental abilities and processes, through surveys. Galton's enquiries covered memory and the association of ideas, visualisation of abstract concepts, and examples of variety in written numerals. The material also comprises papers relating to essays on the human imagination and hallucination, the relative sensitivity of males and females, and the risk of misclassification. The majority of the investigative material in this series forms the basis of Galton's work Inquiries into Human Faculty and its Development (London: MacMillan, 1883). |
