Subclaims¶

q2 i? The two most influential conclusions in feedback research — that feedback improves learning and motivation — were established by Ammons's review despite considerable contradictory evidence, and the review was cited over 100 times since 1965. → Kluger 1996

Evidence¶

Kluger 1996¶

Kluger, A. N., & DeNisi, A. (1996). The effects of feedback interventions on performance: A historical review, a meta-analysis, and a preliminary feedback intervention theory. Psychological Bulletin, 119(2), 254-284. https://doi.org/10.1037/0033-2909.119.2.254

q2 · i? · quant-synthesis · r3

Historical narrative review of early feedback-intervention research. The authors document that Ammons ignored disconfirming evidence (e.g., Pressy's report that FI decreased Russian vocabulary learning) and that a manual SSCI search yielded 100 citations of Ammons's paper since 1965. No effect size is printed for this historical claim.

"Ammons's review was an unfortunate milestone in FI research because he reached the two most influential conclusions in the area—FI improves learning as well as motivation—without serious consideration of the contradictory evidence that was available to him"
