OH I love this: There’s two common models for rapid decision-making: diffusion model and the Linear Ballistic Accumulator LBA). Both operate from VERY different assumptions and have different parameters and YET when used with REAL-WORLD DATA, come to the same conclusions! So, studies done with EITHER MODEL are fine; “The diffusion model and the LBA assume very different frameworks for how rapid decisions are made. We have shown that because of the different frameworks, corresponding parameters do not always map simply between the two models. The mis-mapping is quite specific to how the models describe response caution. Surprisingly, however, in fits to real data, when response caution is experimentally manipulated, the two models lead to the same substantive conclusions (see our Online Appendix for examples). In other words, we find no reason to doubt any previously drawn conclusions using either model.”
