Subclaims¶

q3 i? The slope of P3 amplitude decrease from Block 1 to Block 6 on self-relevant trials was steeper in the joint than the baseline context (phase × context β = −0.11, P = 0.045). → Zheng Zheng & Jun Wang 2024 q3 i? P3 amplitude was significantly larger in the interference Block 7 than Block 6 for self-relevant trials in the joint context, and self-irrelevant trials showed no learning or modulating effects. → Zheng Zheng & Jun Wang 2024 (2)

q3 · i? · causal · r1

Target-onset P3 analysis of actors' EEG on self-relevant trials across learning-phase blocks: significant phase × context interaction (β = −0.11, P = 0.045), steeper decline in the joint context; the quadratic modulating-phase model also fit better; no printed effect size.

"However, the two-way interaction effects of phase × context were signi ficant (β = −0.11, SE = 0.05, t418 = −2.01,P = 0.045). This was indicated by the slope of the P3 amplitude decreasing from Block 1 to Block 6 being steeper in the joint context compared to the baseline context"

q3 · i? · causal · r2

Interference-effect analysis of self-relevant-trial P3: significant phase × context interaction (β = 0.94, P = 0.004), with larger P3 in Block 7 than Block 6 in the joint context (β = 0.77, P < 0.001). For self-irrelevant trials "there were no signi ficant learning effects"; no printed effect size.

"the P3 amplitude was sig- nificantly larger in the Block 7 ( M = 3.81, SE = 0.31) than in Block 6 (M = 3.04, SE = 031) for the joint context ( β =0 . 7 7 ,SE = 0.18, t = 4.25, P < 0.001)"
