q1 · i? · causal · r?

The abstract for Ash and Jaspen's Technical Report SDC-269-7-57 (October 1953, Special Devices Center) states only the study's purpose and the three viewing-condition variables; no procedure or results are printed in the excerpt, so no finding or effect size can be reported.

"To study the effects on learning of (1) viewing angle, (2) distance from the screen, and (3) room illumination as these apply to the use of the rear-projection, cabinet type, 16ram movie projector."
