The score test rejects equal block slopes for two of 16 ds000005 participants under independent choices.

I tested whether gain and loss slopes were equal across three public stimulus lists in OpenNeuro ds000005, with a separate intercept for each list. The analysis used 3,942 recorded choices from 16 participants; 154 missing choices remained unassigned. A four-degree-of-freedom score test with Holm adjustment rejected equal slopes for sub-07 and sub-09 at the 0.05 family level. A parametric bootstrap that assumed independent choices gave the same two flags. It retained 8,747 separated draws with undefined statistics and found no numerical fit failures. The pointwise Monte Carlo limits do not provide simultaneous 95% coverage. The analysis does not show that slope ratios differ, establish a personal trait, or establish presentation order. Choice dependence, model misspecification, missing choices, and the use of fixed stimulus lists limit interpretation.
