From 10.1017/S0140525X18000936:

The biases observed in detection and discrimination experiments led to the development of the two-alternative forced-choice (2AFC) task, in which both stimulus categories are presented on each trial (Macmillan & Creelman 2005). The 2AFC tasks separate the two stimuli either temporally (also referred to as two-interval forced-choice or 2IFC tasks) or spatially. Note that, in recent years, researchers have begun to use the term “2AFC” for two-choice tasks in which only one stimulus is presented. To avoid confusion, we adopt the term “two-stimulus tasks” to refer to tasks where two stimuli are presented (the original meaning of 2AFC) and the term “one-stimulus tasks” to refer to tasks like single-stimulus detection and discrimination (e.g., the tasks discussed in sects. 3.1.1 and 3.1.2).
