Abstract this paper examines. The second question, namely, which of the paradigms (if any) portrays the actual threshold, is more relevant but also more difficult to address, and it may well be that the attentional and memory load that spatial versus temporal paradigms demand make each of them unsuitable for addressing distinct subsets of research topics. In any case, the reasons that this second question escapes examination are that (1) empirically, we cannot collect dependable data that would allow a comparison with "true threshold" because all of our measured thresholds are suspect in these conditions and (2) formally, simulations cannot be carried out to address the issue in the absence of dependable and detailed quantitative knowledge of the particular effects of attention and memory (in spatial versus temporal presentations) on visual performance. Yet, the issue may be irrelevant from a practical point of view as long as thresholds obtained in spatial versus temporal paradigms keep a constant relation to each other and results obtained with spatial versus temporal paradigms in the same or different studies are not compared except to arrive at conclusions regarding differences in the outcomes of each paradigm. Since observing the latter admonition is entirely in the hands of practicing psychophysicists, the work reported in this paper set out to document the relation between thresholds obtained in identical conditions except for the spatial versus temporal arrangement of the 2AFC paradigm
