When restricted to three knowledge-of-results requests per 10-trial block, all three self-controlled groups requested KR mostly on early trials of a block, a massed schedule.¶

Subclaims¶

q2 i? Self-Before and Self-Both used KR requests predominantly on trials 1, 2 and 3; Self-After predominantly on trials 1, 3 and 4. → Carter 2014 q2 i? All three self-controlled groups appear to have favoured more of a massed schedule, requesting KR primarily for early rather than later trials in a block. → Carter 2014 (2)

Carter 2014¶

Carter, M. J., Carlsen, A. N., & Ste-Marie, D. M. (2014). Self-controlled feedback is effective if it is based on the learner’s performance: a replication and extension of Chiviacowsky and Wulf (2005). Frontiers in Psychology, 5, 1325. https://doi.org/10.3389/fpsyg.2014.01325

Descriptive frequency distribution (Table 2) of which trials the self-controlled groups in this experiment chose for KR: "the Self-After group predominantly requested KR on trials 1, 3, and 4". No inferential test is reported.

"Both the Self-Before and the Self-Both groups used their KR requests predominantly on trials 1, 2, and 3 whereas the Self-After group predominantly requested KR on trials 1, 3, and 4."

The authors’ summary of the same descriptive Table 2 data: the groups "appear to have favored more of a massed schedule". No inferential test is reported.

"Thus, all three self-controlled groups appear to have favored more of a massed schedule when using their KR requests wherein KR was requested primarily for early trials rather than later trials in a practice block."

Discussion¶

Related Claims¶

• Self Controlled Learners Do Not Show Lower Error On Requested Kr Trials
• Learners allowed to make a knowledge-of-results decision before a trial and revise it after (Self-Both) mostly kept their original choice but sometimes changed it after seeing their own performance. — related
• During motor practice with knowledge of results, all groups reduced absolute error across blocks, and groups whose KR decision fell after the trial were more accurate during practice than groups whose decision fell before it, independent of choice. — related
• Allowing learners to request knowledge of results before a trial and then revise the choice after it (Self-Both) did not produce learning beyond deciding only after the trial (Self-After), which the authors take as no support for an additive motivational-plus-informational effect. — related
