q3 i? In Experiment 2 (75%), Post phase win rates were significantly larger for relearning old than learning new. → Zhang 2026 q3 i? In Experiment 3 (88%), Post phase win rates replicated the relearning-old advantage, and Post OBR was also greater for relearning old. → Zhang 2026 (2)

Zhang, Y., & Dyson, B. J. (2026). Recover or discover: How outcome feedback shapes response patterns within game spaces. npj Science of Learning. https://doi.org/10.1038/s41539-026-00414-w

q3 · i? · causal · r2

Experiment 2 (75% reinforcement condition, n = 72 analysed): Post win rates favoured relearning old (69.41%) over learning new (59.18%), "t[71] = 4.527, p < .001"; no effect size printed.

"Post phase win rate performance was significantly larger for relearning old relative to learning new (69.41% vs. 59.18%; t[71] = 4.527, p < .001), consistent with the use of strong reinforcement for maintaining prior behaviour."

Experiment 3 (88% reinforcement condition, n = 70 analysed): Post win rates favoured relearning old (72.50%) over learning new (62.22%), "t[69] = 5.130, p < .001"; a significant Learning x Phase OBR interaction also showed Post OBR greater for relearning old (76.34% vs. 63.63%).

"Post results replicated the effect of 75% reinforcement in Experiment 2 that increasing the win rate to 88% maintained the advantage for relearning old response pattern compared to learning new response pattern (72.50% vs. 62.22%; t[69] = 5.130, p < .001)."

Discussion¶

Related Claims¶

• Optimal behaviour is more frequent after wins than after losses, but the after-win advantage is absent in the Post phase and under high reinforcement — related
• Suppression of the old pattern predicts relearning-old success positively under punishment but negatively under reinforcement — related
• Fixing the win rate in the During phase reduces optimal behaviour rates, indicating suppression of the previously learned pattern — related
• Relearning an old response pattern generally beats learning a new one in the Post phase, except under severe 25% punishment — related
• Suppression of the Pre response pattern between Pre and During phases positively predicts Post phase win rates when learning a new pattern, mainly after wins — related
