在本文中，介绍了3个实验任务的2个选择和go/no-go变体的第一个明确的，基于理论的比较。先前的研究质疑，任务的两个变体的潜在核心信息处理是否有所不同，或者它们在响应需求方面是否有所不同。作者研究了每个任务的GO/NO-GO变体的4个不同的扩散模型以及2个选择变体的标准扩散模型（R. Ratcliff，1978）。 2个选择和GO/NO-GO模型适合来自4个词汇决策实验，1个数字歧视实验的数据，以及我识别记忆实验，每个实验都有2个选择和go/no-go变体。假设无需响应的隐式决策标准的模型比没有模型的模型更好。最好的模型是，其中仅响应标准及其处理的非确定组成部分在两个变体之间发生了变化，从而支持这样一种观点，即决策所基于的核心信息之间没有差异。
In this article, the first explicit, theory-based comparison of 2-choice and go/no-go variants of 3 experimental tasks is presented. Prior research has questioned whether the underlying core-information processing is different for the 2 variants of a task or whether they differ mostly in response demands. The authors examined 4 different diffusion models for the go/no-go variant of each task along with a standard diffusion model for the 2-choice variant (R. Ratcliff, 1978). The 2-choice and the go/no-go models were fit to data from 4 lexical decision experiments, 1 numerosity discrimination experiment, and I recognition memory experiment, each with 2-choice and go/no-go variants. The models that assumed an implicit decision criterion for no-go responses produced better fits than models that did not. The best model was one in which only response criteria and the nondecisional components of processing changed between the 2 variants, supporting the view that the core information on which decisions are based is not different between them.
