Subclaims¶

q2 i? Training in canceling 3's and 5's separately improved cancellation of groups containing both 3 and 5, with a trained-control difference of 12.2 seconds attributed to transfer of identical elements. → Poffenberger 1915

Evidence¶

Poffenberger 1915¶

Poffenberger, A. T., Jr. (1915). The influence of improvement in one simple mental process upon other related processes. The Journal of Educational Psychology, 6(8), 459-474. https://doi.org/10.1037/h0075269

q2 · i? · causal · r1

Controlled training experiment on cancellation: trained group averaged 23.7 seconds gain versus 11.5 for controls, a 12.2-second difference about 2.5 times its probable error, with chances of being real about 900 in 1000, roughly 8 per cent of initial performance.

"This difference of 12.2 seconds in favor of the trained group may be attributed to the transfer of the effect of the training. The reliability of this difference expressed in terms of the P. E. of the difference is about 5.0."

Discussion¶

Related Claims¶

• Training in cancellation of 3 and 5 produced neither transfer nor interference on cancellation of groups containing 4 and 7 — related
• Where there are no identical bonds between stimulus and response in two processes, training in one produces neither transfer nor interference in the other — a broader claim this one bears on
• Letter-cancellation practice produced only small gains and some losses in parts-of-speech cancellation, while the unpracticed control group gained on all parts of speech — related
