Evidence¶

Kohs 1914¶

Kohs, S. C. (1914). The Binet-Simon Measuring Scale for Intelligence: An Annotated Bibliography. Part II. The Journal of Educational Psychology. https://www.google.com/search?q=%22Binet-Simon+Measuring+Scale+for+Intelligence%22+Kohs+annotated+bibliography

q2 · i? · review · r?

The review attributes to Goddard's 1913 Journal of Psycho-Asthenics article three annual testings at Vineland of 'three hundred and forty-six feeble-minded boys and girls,' finding 'a vast majority were making no progress mentally,' with conclusions on educational treatment; no effect sizes are printed.

"Three annual testings in the Vineland institution of three hundred and forty-six feeble-minded boys and girls, mentally between one and twelve, chronologically between five and forty, showed that a vast majority were making no progress mentally."
