Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Groups given single trials in various combinations of the units, including the fully reversed order IV, III, II, I, never averaged higher than 2/5ths errors per day, showing absolute control over units kept as units. → Pechstein 1917
Evidence¶

q2 · i? · causal · r1
Groups taught the four units were given a single trial in various unit combinations, such as the reversed order IV, III, II, I, made possible by the common-center entrances and exits. "In no case did the groups average higher than 2/5ths errors per day."
"In no case did the groups average higher than 2/5ths errors per day. The subjects showed almost constant ability to adjust to changing requirements day after day"
Discussion¶
Related Claims¶
- The motor habit for a maze section shows practically no disintegration over the intervals between part-learning trials — related
- Retro-active inhibition does not explain part learners' failure, since unit I retained almost perfect control — related
- For rats, whole and part maze learning show no difference in trials, but the whole method saves time and errors — related
- Short maze units learned under massed conditions connect into a serial whole with great economy, whereas units learned under distributed conditions connect only with extreme difficulty — related
