Subclaims¶

q2 i? The form board should be given at least three times because scores improve from test to test and repetition effects vary by intelligence, type, age, and sex; the best record in three trials is the fairest single index. → Wallin 1915

Evidence¶

Wallin 1915¶

Wallin, J. E. W. (1915). Age Norms of Psycho-Motor Capacity. The Journal of Educational Psychology. https://search.worldcat.org/search?q=Age+Norms+of+Psycho-Motor+Capacity

q2 · i? · causal · r1

Methodological conclusion from the author's analysis of repetition effects across the form-board records. He reports that average scores improve from test to test and that girls gain relatively more from repetition while epileptics often do poorer in later trials.

"For these and other reasons the fairest single index by which to gauge the psycho-motor efficiency of an individual by this form-board is the best record in the three trials."
